ssm整合時的配置文件

一、web.xml

1、配置監聽器，用來掃描classpath:applicationContext-*.xml下面的各類配置文件

<!-- 配置Spring的配置文件 去加載spring的配置文件 -->
    <listener>
	<!-- 默認是去WEB-INF下找 applicationContext.xml配置文件-->
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	
	</listener>  
	
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext-*.xml</param-value>
	</context-param>

2、配置SPringMVC的核心處理器 DispatcherServlet

url-patten標籤說明：

• 1./* 攔截所有請求 css img js jsp html action
• 2.*.action/*.do *.action 可以攔截以.action結尾的請求 
• 3./ 攔截css js image action請求 不攔截jsp(推薦) 

<servlet>
		<servlet-name>DispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<!-- contextConfigLocation固定 -->
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-mvc.xml</param-value>
		</init-param>
		<!-- 啓動服務器就實例化 -->
		<load-on-startup>1</load-on-startup>

	</servlet>

	<servlet-mapping>
		<servlet-name>DispatcherServlet</servlet-name>
		<!-- 1./* 攔截所有請求 css img js jsp html action 2.*.action/*.do *.action 可以攔截以.action結尾的請求 
			3./ 攔截css js image action請求 不攔截jsp(推薦) -->
		<url-pattern>/</url-pattern>

	</servlet-mapping>

 

3、SPring解決POST請求亂碼

<filter>
		<filter-name>characterEncodingFilter</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>characterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

 

4、form表單只支持 Get和POST  如果想支持rest風格  得配置該過濾器  然後該過濾器會幫我們實現

<filter>
		<filter-name>HiddenHttpMethodFilter</filter-name>
		<filter-class>
			org.springframework.web.filter.HiddenHttpMethodFilter
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>HiddenHttpMethodFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

5、rest請求的過濾器

     <filter>
		<filter-name>HiddenHttpMethodFilter</filter-name>
		<filter-class>
			org.springframework.web.filter.HiddenHttpMethodFilter
		</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>HiddenHttpMethodFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

二、spring-mvc.xml中的配置

靜態資源static文件夾放在webapp文件夾下面

<?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:p="http://www.springframework.org/schema/p"
	    xmlns:context="http://www.springframework.org/schema/context"
	    xmlns:aop="http://www.springframework.org/schema/aop"
	    xmlns:tx="http://www.springframework.org/schema/tx"
	    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
       http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">
       
       <!-- 開發SpringMvc的配置文件 -->
      
       <context:component-scan base-package="com.ssm.controller"></context:component-scan>
        <!-- 開啓組件掃描 -->
     	<mvc:annotation-driven></mvc:annotation-driven>
     	
       <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       		
       		<property name="prefix" value="/WEB-INF/jsp/"></property>
       		<property name="suffix" value=".jsp" ></property>
       		
       </bean>
       
       <!-- 用來過濾靜態資源法 -->
       <mvc:resources location="/static/" mapping="/static/**"></mvc:resources>
       
       <!-- 配置文件上傳相關 -->
       	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"
       	p:defaultEncoding="utf-8"
       	p:maxUploadSize="1048576"
       	p:uploadTempDir="file:D:\temp"
   		>
       	</bean>
       </beans>

三、applicationContext-service.xml中的配置

 開啓事務註解驅動的情況下需要要在service層加@Transactional註解，不然就用如下注釋中的<tx:advice id="txAdvice" transaction-manager="transactionManager">的方式

<?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:p="http://www.springframework.org/schema/p"
	    xmlns:context="http://www.springframework.org/schema/context"
	    xmlns:aop="http://www.springframework.org/schema/aop"
	    xmlns:tx="http://www.springframework.org/schema/tx"
	    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
       http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">
       
       <!-- 開發SpringMvc的配置文件 -->
       <!-- 開啓組件掃描 -->
       <context:component-scan base-package="com.ssm.service"></context:component-scan>
       
       	<!-- 配置事務 -->
       	<!-- 配置平臺事務管理器 -->
       	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       		<!-- 現在注入dataSource -->
       		<property name="dataSource" ref="dataSource"></property>
       	</bean>
       	<!-- 事務註解驅動 -->
       <tx:annotation-driven transaction-manager="transactionManager"/>
       	
       	<!-- 配置事務通知 -->
       	<!-- <tx:advice id="txAdvice" transaction-manager="transactionManager">
       		<tx:attributes>
       			<tx:method name="select*" propagation="SUPPORTS" read-only="true"/>
       			<tx:method name="query*" propagation="SUPPORTS" read-only="true"/>
       			<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
       			<tx:method name="search*" propagation="SUPPORTS" read-only="true"/>
       			<tx:method name="get*" propagation="SUPPORTS" read-only="true"/>
       			
       			
       			<tx:method name="add*" propagation="REQUIRED" />
       			<tx:method name="save*" propagation="REQUIRED" />
       			<tx:method name="insert*" propagation="REQUIRED" />
       			<tx:method name="delete*" propagation="REQUIRED" />
       			<tx:method name="update*" propagation="REQUIRED" />
       			<tx:method name="modify*" propagation="REQUIRED" />
       			<tx:method name="remove*" propagation="REQUIRED" />
       			
       			<tx:method name="*" propagation="REQUIRED" />
       		
       		</tx:attributes>
       	
       	</tx:advice> -->
       	
       	<!-- 配置aop -->
       	
       	<!-- <aop:config proxy-target-class="true">
	       	<aop:pointcut expression="execution( public * com.ssm.service.impl.*.*(..))" id="cut"/>
	       	<aop:advisor advice-ref="txAdvice" pointcut-ref="cut"/>
       	</aop:config> -->
      
       
       </beans>

四、applicationContext-dao.xml的配置

此處省去了頭文件，使用了druid連接池，c3p0，dbcp,連接池單獨放下面

       <!-- 開啓組件掃描 -->
       <context:component-scan base-package="com.ssm.mapper"></context:component-scan>
       
        <context:property-placeholder location="classpath:*.properties"/>
       
        <!-- 配置數據源 -->
        <!-- 配置druid連接池 -->
       <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<property name="driverClassName" value="${jdbc.driver}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
		<!-- 配置初始化大小、最小、最大 -->
		<property name="initialSize" value="20" />
		<property name="minIdle" value="3" />
		<property name="maxActive" value="100" />

		<!-- 配置獲取連接等待超時的時間 -->
		<property name="maxWait" value="10000" />

	<!-- 配置間隔多久才進行一次檢測，檢測需要關閉的空閒連接，單位是毫秒 -->
		<property name="timeBetweenEvictionRunsMillis" value="60000" />

		<!-- 配置一個連接在池中最小生存的時間，單位是毫秒 -->
		<property name="minEvictableIdleTimeMillis" value="300000" />

		<property name="testWhileIdle" value="true" />

		<!-- 這裏建議配置爲TRUE，防止取到的連接不可用 -->
		<property name="testOnBorrow" value="true" />
		<property name="testOnReturn" value="false" />

		<!-- 打開PSCache，並且指定每個連接上PSCache的大小 -->
		<property name="poolPreparedStatements" value="true" />
		<property name="maxPoolPreparedStatementPerConnectionSize"
			value="20" />

		<!-- 這裏配置提交方式，默認就是TRUE，可以不用配置 -->

		<property name="defaultAutoCommit" value="true" />

		<!-- 驗證連接有效與否的SQL，不同的數據配置不同 -->
		<property name="validationQuery" value="select 1 " />
		<property name="filters" value="stat" />
	</bean>
  
       <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
       	<property name="dataSource" ref="dataSource"></property>
       	<!-- 配置別名,類名不區分大小寫 -->
       	<property name="typeAliasesPackage" value="com.ssm.model"></property>
       
       	<!-- 引入sql映射文件 -->
       	<property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>
       	
       	<!-- 配置分頁 -->
	    <property name="plugins">
		<array>
			<bean class="com.github.pagehelper.PageInterceptor">
				<!-- 配置參數 -->
				<property name="properties">
					<value>
						helperDialect=mysql
					</value>
				</property>
			</bean>
		</array>
	</property>
       	
       </bean>
       
      <!--  <bean id="userMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
       	注入接口 模擬類
       	<property name="mapperInterface" value="com.ssm.mapper.userMapper"></property>
       	注入sqlsossionfactory
       	<property name="sqlSessionFact" value="sqlSessionFactory"></property>
       </bean> -->
       
       <!-- id默認是接口名小寫 -->
       <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
       	<property name="basePackage" value="com.ssm.mapper"></property>
       	<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
       
       </bean> 
       </beans>

java自己的連接池

 <bean id="dateSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="username" value="root"></property>
		<property name="password" value="123"></property>
		<property name="url" value="jdbc:mysql:///hibernate?useUnicode=true&amp;characterEncoding=utf8"></property>
		<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
	</bean>

c3p0連接池配置

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    	<property name="user" value="${jdbc.username}"></property>
    	<property name="password" value="${jdbc.password}"></property>
    	<property name="jdbcUrl" value="${jdbc.url}"></property>
    	<property name="driverClass" value="${jdbc.driverClassName}"></property>
    	<property name="maxPoolSize" value="${jdbc.maxPoolSize}"></property>
    	<property name="initialPoolSize" value="${jdbc.initialPoolSize}"></property>
    </bean>

DBCP連接池

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="username" value="${jdbc.username}"></property>
		<property name="password" value="${jdbc.password}"></property>
		<property name="url" value="${jdbc.url}"></property>
		<property name="driverClassName" value="${jdbc.driverClassName}"></property>
	</bean>

 jdbc.properties文件

jdbc.username=root
jdbc.password=123
jdbc.url=jdbc:mysql:///hibernate?useUnicode=true&characterEncoding=utf8
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.maxPoolSize=200
jdbc.initialPoolSize=20

五、log4j.properties測試文件，需要引入相關jar包

# Global logging configuration
log4j.rootLogger=INFO, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.err
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

 六、service層

在service實現類中直接注入mybatis的UserMapper接口類，前提是在applicationContext-dao.xml中配置瞭如下內容，以實現接口的實現類

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
       	<property name="basePackage" value="com.ssm.mapper"></property>
       	<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
       </bean>

 

@Service
@Transactional
public class UserServiceImpl implements UserService{
	@Autowired
	private UserMapper userMapper;
	@Override
	public List<User> queryAllUser() {
		List<User> list = userMapper.queryAllUser();
		//System.out.println("service");
		return list;
	}

}

七、mapper包

UserMapper接口

public interface UserMapper {

	List<User> queryAllUser();
	
}

UserMapper.xml映射文件：

resultType="user"前提是在applicationContext-dao.xml中配置了別名

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.ssm.mapper.UserMapper">

	<select id="queryAllUser"  resultType="user">
		select * from tb_user 
	</select>
</mapper>

 別名：

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
       	<property name="dataSource" ref="dataSource"></property>
       	<!-- 配置別名,類名不區分大小寫 -->
       	<property name="typeAliasesPackage" value="com.ssm.model"></property>
       
       	<!-- 引入sql映射文件 -->
       	<property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>
      
       </bean>

若要使用分頁需要在pom中引入依賴：

<dependency>
			<groupId>com.github.pagehelper</groupId>
			<artifactId>pagehelper</artifactId>
			<version>${mybatis.pagehelper.version}</version>
		</dependency>

七、控制器層測試

@Controller
public class UserController {
	@Autowired
	private UserService userService;
		
	@RequestMapping("/showUser")
	public String showUser(Model model,@RequestParam(defaultValue="4")Integer pageSize,
			@RequestParam(defaultValue="1")Integer currentPage) {
		Page<Object> page = PageHelper.startPage(currentPage, pageSize);//
		
		List<User> list = userService.queryAllUser();
		
		PageInfo<User> pageInfo = new PageInfo<>(list, 4);
		model.addAttribute("list", list);
		model.addAttribute("NavigatepageNums", pageInfo.getNavigatepageNums());
		
		model.addAttribute("page",pageInfo);
		
		return "allusers";
		//return "allUser";
	}
}
