Maven搭建springmvc hibernate環境

搭建SpringMVC4.1.4和Hibernate4.3.8，持久層採用Hibernate，數據源採用c3p0，數據庫採用MySQL

步驟如下：

  1、設計數據庫：設計好表結構，最好符合3NF，採用Hibernate tools將設計好的表自動生成對應的實體entity。 

     2、創建Maven項目，按需映入Maven包依賴。

     3、搭建Spring：配置Spring對控件層Bean的注入。

     4、搭建Hibernate：配置數據源，配置SessionFactory，配置事務，以及二級緩存ehcache的配置。

     5、測試Spring+Hibernate的框架搭建，寫單元測試JUnit，測試事務配置等。

     6、映入SpringMVC：配置SpringMVC配置信息。

     7、配置web.xml容器

     8、測試三個框架的整合：Maven編譯打包部署服務器，測試。

1、數據庫設計

       設計一個權限、角色、用戶的表。自然如果一個用戶可以有多個角色，一個角色多個用戶所擁有；一個角色擁有多個權限，一個權限對應多個角色。所以按照數據庫 表結構設計，符合3NF的話我們需要5張表進行存在。表的具體信息就不列出了（可以下在源碼，裏面還有數據庫），表關係如下：

       

      這裏面ID纔用到是java的UUID（36位）

2、創建Maven項目，編寫pom.xml文件

      創建一個Maven的webapp項目，編寫pom.xml文件，引入所需的包依賴，我這裏就將所需的全部的映入了。

        

      pom.xml文件內容如下:

       

  <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3、引入Spring配置

    編寫配置文件，配置文件放在src/main/resources資源目錄下（下同）。

   項目所需的配置信息config.properties

  

#application configs

#jdbc c3p0 config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/work?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = 12345

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update
hibernate.cache.use_second_level_cache = true
hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path = ehcache.xml

3.1、spring配置

spring.xml的配置文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
			http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
			http://www.springframework.org/schema/context
			http://www.springframework.org/schema/context/spring-context-4.1.xsd">
	<!-- 加載配置文件 -->
	
	<context:property-placeholder location="classpath:config.properties"/>
	<!-- 掃描service自動注入爲bean -->
	<context:component-scan base-package="org.andy.work.service.impl,org.andy.work.dao.impl" />

</beans>

上面spring配置了對應包下組件bean自動注入管理，我們需要將dao,service的實現類交由spring管理，如（@Repository，@Service）。

3.2、引入日誌文件配置Log4j

  log4j.properties的配置文件如下：

 

### set log levels ###
log4j.rootLogger = INFO , C , D , E 

### console ###
log4j.appender.C = org.apache.log4j.ConsoleAppender
log4j.appender.C.Target = System.out
log4j.appender.C.layout = org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### log file ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = ../logs/springmvc_hibernate_demo.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = INFO 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = [springmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

### exception ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File = ../logs/springmvc_hibernate_demo_error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [sspringmvc_hibernate_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n

4、Hibernate配置

      Hibernate的配置主要包括：配置數據源c3p0，配置SessionFactory，配置事務管理器，配置事務管理，其spring-hibernate.xml文件如下：

     

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
		http://www.springframework.org/schema/tx 
		http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
		http://www.springframework.org/schema/aop 
		http://www.springframework.org/schema/aop/spring-aop-4.1.xsd">

	<!-- 配置數據源 c3p0 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
		destroy-method="close">
		<property name="driverClass" value="${jdbc.driver}" />
		<property name="jdbcUrl" value="${jdbc.url}" />
		<property name="user" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />

		<!-- 請求超時時間 -->
		<property name="checkoutTimeout" value="30000" />
		<!-- 每60秒檢查所有連接池中的空閒連接。默認值: 0，不檢查 -->
		<property name="idleConnectionTestPeriod" value="30" />
		<!-- 連接數據庫連接池最大空閒時間 -->
		<property name="maxIdleTime" value="30" />
		<!-- 連接池初始化連接數 -->
		<property name="initialPoolSize" value="5" />
		<property name="minPoolSize" value="5" />
		<property name="maxPoolSize" value="20" />
		<!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。默認值: 3 -->
		<property name="acquireIncrement" value="5" />
	</bean>

	<!-- 配置hibernate的SessionFactory -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
		<!-- 注入數據源 相關信息看源碼 -->
		<property name="dataSource" ref="dataSource" />
		<!-- hibernate配置信息 -->
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">${hibernate.dialect}</prop>
				<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
				<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
				<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>

				<!-- 開啓二級緩存 ehcache -->
				<prop key="hibernate.cache.use_second_level_cache">${hibernate.cache.use_second_level_cache}</prop>
				<prop key="hibernate.cache.use_query_cache">${hibernate.cache.use_query_cache}</prop>
				<prop key="hibernate.cache.region.factory_class">${hibernate.cache.region.factory_class}</prop>
				<prop key="hibernate.cache.provider_configuration_file_resource_path">${hibernate.cache.provider_configuration_file_resource_path}
				</prop>
			</props>
		</property>
		<!-- 掃描hibernate註解配置的entity -->
		<property name="packagesToScan" value="org.andy.work.entity" />
	</bean>

	<!-- 配置事務管理器 -->
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate4.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

	<!-- 配置事務增強處理Bean，指定事務管理器 -->
	<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
		<!-- 配置詳細事務處理語義 -->
		<tx:attributes>
			<tx:method name="insert*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />
			<tx:method name="delete*" propagation="REQUIRED" />

			<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="find*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="select*" propagation="SUPPORTS" read-only="true" />
			<tx:method name="load*" propagation="SUPPORTS" read-only="true" />

			<!-- 其他採用默認事務方式 -->
			<tx:method name="*" />

		</tx:attributes>
	</tx:advice>

	<!-- Spring aop事務管理 -->
	<aop:config>
		<!-- 配置切入點 -->
		<aop:pointcut id="transactionPointcut"
			expression="execution(* org.andy.work.service..*Impl.*(..))" />
		<!-- 指定在txAdvice切入點應用txAdvice事務增強處理 -->
		<aop:advisor pointcut-ref="transactionPointcut"
			advice-ref="transactionAdvice" />
	</aop:config>

</beans>

     上面配置了二級緩存，ehcache，相關的具體信息查看上一篇Hibernate二級緩存以及ehcache的搭建配置，下面是二級緩存的配置。

4.1、ehcache.xml的配置

       

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
	<diskStore path="D:/ehcache" />
	<!-- DefaultCache setting. -->
     <defaultCache
            maxElementsInMemory="1000"
            eternal="false"
            timeToIdleSeconds="120"
            timeToLiveSeconds="120"
            maxElementsOnDisk="1000000"
            overflowToDisk="true" 
            memoryStoreEvictionPolicy="LRU">
            
    </defaultCache>

	<!-- Special objects setting. -->

	<cache 
	     name="org.andy.work.entity.AcctUser"
		 maxElementsInMemory="2"
		 memoryStoreEvictionPolicy="LRU" 
		 eternal="true" 
		 diskPersistent="false"
		 overflowToDisk="false" 
		 maxElementsOnDisk="1000000" /> 



</ehcache>

   上面Hibernate二級緩存ehcache存放磁盤是D:/ehcache

5、生成業務entity實體

      設計好數據表後，Hibernate的實體有工具Hibernate tools自動生成，Eclipse需要安裝Hibernate tools插件（我在線安裝過幾次都不成功，推薦使用links離線安裝，附錄將介紹），所以不需要手工的書寫，下面就貼一個用戶信息的實 體，AcctUser.java

     

package org.andy.work.entity;

// Generated 2015-2-3 10:43:00 by Hibernate Tools 4.0.0

import java.util.Date;
import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.Table;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

/**
 * AcctUser generated by hbm2java
 */
@Entity
@Table(name = "acct_user", catalog = "work")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class AcctUser implements java.io.Serializable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 6980093847795726310L;
	private String id;
	private String nickName;
	private String telephone;
	private Date registerTime;
	private Set<AcctRole> acctRoles = new HashSet<AcctRole>(0);

	public AcctUser() {

	}

	public AcctUser(String id, String nickName) {
		this.id = id;
		this.nickName = nickName;
	}

	public AcctUser(String id, String nickName, String telephone,
			Date registerTime, Set<AcctRole> acctRoles) {
		this.id = id;
		this.nickName = nickName;
		this.telephone = telephone;
		this.registerTime = registerTime;
		this.acctRoles = acctRoles;
	}

	@Id
	@Column(name = "id", unique = true, nullable = false, length = 36)
	public String getId() {
		return this.id;
	}

	public void setId(String id) {
		this.id = id;
	}

	@Column(name = "nick_name", nullable = false)
	public String getNickName() {
		return this.nickName;
	}

	public void setNickName(String nickName) {
		this.nickName = nickName;
	}

	@Column(name = "telephone")
	public String getTelephone() {
		return this.telephone;
	}

	public void setTelephone(String telephone) {
		this.telephone = telephone;
	}

	@Temporal(TemporalType.TIMESTAMP)
	@Column(name = "register_time", length = 19)
	public Date getRegisterTime() {
		return this.registerTime;
	}

	public void setRegisterTime(Date registerTime) {
		this.registerTime = registerTime;
	}

	@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})
	@ManyToMany(fetch = FetchType.LAZY)
	@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
	@JoinTable(name = "acct_user_role", catalog = "work", joinColumns = { @JoinColumn(name = "user_id", nullable = false, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "role_id", nullable = false, updatable = false) })
	public Set<AcctRole> getAcctRoles() {
		return this.acctRoles;
	}

	public void setAcctRoles(Set<AcctRole> acctRoles) {
		this.acctRoles = acctRoles;
	}

}

上面有幾個需要注意的：

     上面大多數都是Hibernate tools自動生成的，但是有幾個需要手動添加：

              1、如果這個實體使用二級緩存的話，需要添加@cache註解；

              2、如果該實體裏面還有集合元素（set， map，list），如果實體要採用二級緩存，那麼這些集合元素必須也添加@cache註解。

              3、@JsonIgnoreProperties註解是爲了防止SpringMVC在json返回時產生循環輸出使用，如果不配置的話就會出現json死循環（還有多對多，一對多的屬性時）。

             4、@JsonIgnore這個是在轉換成json是忽略該屬性，而@JsonIgnoreProperties(value={"acctUsers", "acctAuthorities"})則是忽略acctRoles裏面的acctUsers和acctAuthorites屬性。

6、創建Dao層

6.1Dao接口

              Dao層和Service層我們肯定採用的是面相接口編程的思想，所以，我們先定義一個通用的Dao接口，GenericDao.java

            

package org.andy.work.dao;

import java.io.Serializable;
import java.util.List;

/**
 * 創建時間：2015-2-6 下午2:26:42
 * 
 * @author andy
 * @version 2.2
 * 
 * Dao通用接口
 */

interface GenericDao<T, PK extends Serializable> {
	
	T load(PK id);
	
	T get(PK id);
	
	List<T> findAll();
	
	void persist(T entity);
	
	PK save(T entity);
	
	void saveOrUpdate(T entity);
	
	void delete(PK id);
	
	void flush();
}

            在定義具體的UserDao.java接口

           

package org.andy.work.dao;

import org.andy.work.entity.AcctUser;

/**
 * 創建時間：2015-2-6 下午2:43:50
 * 
 * @author andy
 * @version 2.2
 * 
 * 用戶Dao接口
 */

public interface UserDao extends GenericDao<AcctUser, String> {

}

6.2、Dao層實現類

    我們需要將Dao層的實現類注入爲bean，所以需要添加@Repository註解，UserDaoImpl如下：

package org.andy.work.dao.impl;

import java.util.List;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctUser;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

/**
 * 創建時間：2015-2-6 下午2:45:14
 * 
 * @author andy
 * @version 2.2
 */
@Repository("userDao")
public class UserDaoImpl implements UserDao {

	@Autowired
	private SessionFactory sessionFactory;

	private Session getCurrentSession() {
		return this.sessionFactory.getCurrentSession();
	}

	@Override
	public AcctUser load(String id) {
		return (AcctUser) this.getCurrentSession().load(AcctUser.class, id);
	}
	
	@Override
	public AcctUser get(String id) {
		return (AcctUser) this.getCurrentSession().get(AcctUser.class, id);
	}

	@SuppressWarnings("unchecked")
	@Override
	public List<AcctUser> findAll() {
		List<AcctUser> acctUsers = this.getCurrentSession().createQuery("from AcctUser").setCacheable(true).list();
		return acctUsers;
	}

	@Override
	public void persist(AcctUser entity) {
		this.getCurrentSession().persist(entity);

	}

	@Override
	public String save(AcctUser entity) {
		return (String) this.getCurrentSession().save(entity);
	}

	@Override
	public void saveOrUpdate(AcctUser entity) {
		this.getCurrentSession().saveOrUpdate(entity);
	}

	@Override
	public void delete(String id) {
		AcctUser entity = this.load(id);
		this.getCurrentSession().delete(entity);
	}

	@Override
	public void flush() {
		this.getCurrentSession().flush();

	}

}

 

7、創建Service層

  7.1、Service層接口

package org.andy.work.service;

import java.util.List;

import org.andy.work.entity.AcctUser;

/**
 * 創建時間：2015-2-6 下午3:18:57
 * 
 * @author andy
 * @version 2.2
 *  userService接口
 */

public interface UserService {
	AcctUser load(String id);

	AcctUser get(String id);

	List<AcctUser> findAll();

	void persist(AcctUser entity);

	String save(AcctUser entity);

	void saveOrUpdate(AcctUser entity);

	void delete(String id);

	void flush();
}

  7.2、service層實現類

   UserServiceImpl就需要注入上面定義的Dao層bean。

 

package org.andy.work.service.impl;

import java.util.List;

import org.andy.work.dao.UserDao;
import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * 創建時間：2015-2-6 下午3:24:16
 * 
 * @author andy
 * @version 2.2 UserService 的實現
 */
@Service("userService")
public class UserServiceImpl implements UserService {

	@Autowired
	private UserDao userDao;

	@Override
	public AcctUser load(String id) {
		return userDao.load(id);
	}

	@Override
	public AcctUser get(String id) {
		return userDao.get(id);
	}

	@Override
	public List<AcctUser> findAll() {
		return userDao.findAll();
	}

	@Override
	public void persist(AcctUser entity) {
		userDao.persist(entity);
	}

	@Override
	public String save(AcctUser entity) {
		return userDao.save(entity);
	}

	@Override
	public void saveOrUpdate(AcctUser entity) {
		userDao.saveOrUpdate(entity);
	}

	@Override
	public void delete(String id) {
		userDao.delete(id);
	}

	@Override
	public void flush() {
		userDao.flush();
	}

}

 

8、測試Spring和Hibernate的整合

    我們可以在src/test/java編寫測試類，測試上面的配置，如果測試成功已經基本大功告成。

 

package org.andy.work.service;

import java.util.Date;
import java.util.List;
import java.util.UUID;

import org.andy.work.entity.AcctUser;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.alibaba.fastjson.JSON;

/**
 * 創建時間：2015-2-6 下午3:31:07
 * 
 * @author andy
 * @version 2.2
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:spring.xml",
		"classpath:spring-hibernate.xml" })
public class TestUserService {

	private static final Logger LOGGER = Logger
			.getLogger(TestUserService.class);

	@Autowired
	private UserService userService;

	@Test
	public void save() {
		AcctUser acctUser = new AcctUser();
		acctUser.setId(UUID.randomUUID().toString());
		acctUser.setNickName("andy");
		acctUser.setRegisterTime(new Date());
		acctUser.setTelephone("13022221111");
		String id = userService.save(acctUser);
		LOGGER.info(JSON.toJSONString(id));
	}

}

 

9、引入SpringMVC

     添加spring-mvc.xml文件

  

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans-4.1.xsd 
		http://www.springframework.org/schema/context 
		http://www.springframework.org/schema/context/spring-context-4.1.xsd 
		http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">

	<!-- 自動掃描@Controller注入爲bean -->
	<context:component-scan base-package="org.andy.work.controller" />

	<!-- 以下爲SpringMVC配置 -->
	<mvc:annotation-driven>
		<!-- 返回json數據，@response使用 -->
		<mvc:message-converters register-defaults="true">
			<bean
				class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
				<property name="supportedMediaTypes">
					<list>
						<value>text/html;charset=UTF-8</value>
						<value>application/json;charset=UTF-8</value>
					</list>
				</property>

			</bean>
		</mvc:message-converters>
	</mvc:annotation-driven>

	<!-- 對模型視圖名稱的解析，即在模型視圖名稱添加前後綴 -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/views" />
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

   上面配置了包掃描Controller，[email protected]��，和視圖層的配置。

10、配置web.xml容器

      web容器是web項目的大腦，所以web容器，首先需要引入spring，讓spring管理各個框架，並將其注入爲bean。然後配置控制層的filter信息。並且配置了springmvc攔截的url爲以.hmls結尾的請求。

web.xml文件如下：

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">

	<display-name>springmvc_demo</display-name>

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
	</context-param>

	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- openSessionInView配置 作用是延遲session關閉到view層 -->
	<filter>
		<filter-name>openSessionInViewFilter</filter-name>
		<filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>
		<init-param>
			<param-name>singleSession</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>

	<!-- 監聽servletContext，啓動contextConfigLocation中的spring配置信息 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- 防止spring內存溢出監聽器 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>

	<servlet>
		<description>spring mvc servlet</description>
		<servlet-name>rest</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<!-- 此處配置的是SpringMVC的配置文件 -->
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>rest</servlet-name>
		<url-pattern>*.htmls</url-pattern>
	</servlet-mapping>

	<filter-mapping>
		<filter-name>openSessionInViewFilter</filter-name>
		<url-pattern>*.htmls</url-pattern>
	</filter-mapping>

	<!-- 配置session超時時間，單位分鐘 -->
	<session-config>
		<session-timeout>30</session-timeout>
	</session-config>

	<welcome-file-list>
		<welcome-file>/index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

 

11、創建控制層Controller

     控制層UserController

package org.andy.work.controller;

import java.util.List;

import org.andy.work.entity.AcctUser;
import org.andy.work.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**  
 * 創建時間：2015-2-7 上午11:49:00  
 * @author andy  
 * @version 2.2  
 * 描述： 用戶Controller
 */
@Controller
@RequestMapping("/user")
public class UserController {

	private static final Logger LOGGER = Logger.getLogger(UserController.class);
	
	@Autowired
	private UserService userService;
	
	@RequestMapping("/showInfo/{userId}")
	public String showUserInfo(ModelMap modelMap, @PathVariable String userId){
		LOGGER.info("查詢用戶：" + userId);
		AcctUser userInfo = userService.load(userId);
		modelMap.addAttribute("userInfo", userInfo);
		return "/user/showInfo";
	}
	
	@RequestMapping("/showInfos")
	public @ResponseBody List<AcctUser> showUserInfos(){
		LOGGER.info("查詢用戶全部用戶");
		List<AcctUser> userInfos = userService.findAll();
		return userInfos;
	}
}

12、創建視圖層

   在src/main/webapp/WEB-INF/views下 創建user/showInfo.jsp

      

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>

<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<base href="<%=basePath%>" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>
<title>userInfo</title>
</head>
<body>
	用戶信息 暱稱： ${userInfo.nickName} 用戶id：${userInfo.id} 用戶電話:${userInfo.telephone } 註冊時間：
	<fmt:formatDate value="${userInfo.registerTime }" pattern="yyyy-MM-dd HH:mm:ss" />
	角色：[
	<c:forEach items="${ userInfo.acctRoles}" var="role">
	                    ${role.name }   權限[
	                       <c:forEach items="${ role.acctAuthorities}" var="authority">
	                         ${authority.name } 
	                       </c:forEach> ]
	                  </c:forEach>
	]

	<br /> ajax顯示全部用戶信息：
	<div id="show_all_user"></div>
</body>
<script type="text/javascript">
	$.ajax({
		type : "get",
		url : "user/showInfos.htmls",
		dataType : "json",
		success : function(data) {
			$(data).each(
					function(i, user) {
						var p = "<p>暱稱:" + user.nickName + "    電話:"
								+ user.telephone + "    註冊時間:"
								+ user.registerTime + "    id:" + user.id +
						"</p>";
						$("#show_all_user").append(p);
					});
		},
		async : true
	});
</script>
</html>

13、部署服務器測試

          使用Maven打包部署：clean compile  package

          部署到tomcat，測試

          主要測試上面的  http://localhost:8080/springmvc_hibernate_demo/user/showInfo/6e5afb1d-50e1-45fe-b6fe-b9e399415387.htmls

                                  和http://localhost:8080/springmvc_hibernate_demo/user/showInfos.htmls  （json數據返回）

          上面視圖層就包含了這兩條url請求的測試：

        

     ok，到此Spring+SpringMVC+Hibernate搭建完畢。
