1、創建項目

2、在main文件夾下新建一個java文件夾，設置爲sourceRoot類型

3、在main文件夾下新建一個Resources文件夾，設置爲Resources Root類型

4、導入pom文件的相關依賴

5、在Resources文件目錄下創建如下配置文件

1、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">
    <!-- 引入資源文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!-- 自動掃描與裝配bean-->
    <context:component-scan base-package="dao.*,service.*"/>
    <!--引入註解解析器-->
    <context:annotation-config/>
    <!-- 數據源連接池 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClass}"/>
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"/>
        <property name="user" value="${jdbc.user}"/>
        <property name="password" value="${jdbc.password}"/>
        <property name="minPoolSize" value="${jdbc.minPoolSize}"/>
        <property name="maxPoolSize" value="${jdbc.maxPoolSize}"/>
        <property name="initialPoolSize" value="${jdbc.initialPoolSize}"/>
    </bean>
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="hibernateProperties">
            <props>
                <!--配置Hibernate的方言-->
                <prop key="hibernate.dialect">
                    org.hibernate.dialect.MySQLDialect
                </prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>

                <!--格式化輸出sql語句-->
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.use_sql_comments">false</prop>
            </props>
        </property>
        <!-- 自動掃描實體 -->
        <property name="packagesToScan"  value="entity" />
    </bean>
    <!-- 配置 HibernateTemplate 對象 -->
    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate">
        <!-- 注入 SessionFactory 對象 -->
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <!-- 用註解來實現事務管理 -->
    <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <tx:annotation-driven transaction-manager="txManager"/>
</beans>

2、jdbc.properties

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/hibernate?characterEncoding=utf-8&autoReconnect=true&useSSL=false
jdbc.user=root
jdbc.password=root
#連接池中保留的最小連接數
jdbc.minPoolSize=1
#連接池中保留的最大連接數
jdbc.maxPoolSize=20
#初始化連接數
jdbc.initialPoolSize=1

3、struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <!-- 開啓使用開發模式，詳細錯誤提示 -->
    <constant name="struts.devMode" value="true" />
    <!-- 將對象交給spring管理 -->
    <constant name="struts.objectFactory" value="spring" />
    <!-- 指定資源編碼類型 -->
    <constant name="struts.i18n.encoding" value="UTF-8" />
    <!-- 指定每次請求到達，重新加載資源文件 -->
    <constant name="struts.i18n.reload" value="false" />
    <!-- 指定每次配置文件更改後，自動重新加載 -->
    <constant name="struts.configuration.xml.reload" value="false" />
    <!-- 默認後綴名 -->
    <constant name="struts.action.extension" value="action," />
    <!-- 指定上傳文件的大小上限 -->
    <constant name="struts.multipart.maxSize" value="209715200" />
    <!-- 瀏覽器是否緩存靜態內容，生產環境下需要設置爲true -->
    <constant name="struts.serve.static.browserCache" value="true" />
    <!-- 開啓動態方法調用 -->
    <constant name="struts.enable.DynamicMethodInvocation" value="false" />
    <!--package包作用是管理action 通常一個業務模塊 用一個包  在struts中包一定要繼承struts-default包
        還有一個namespace 作爲路徑的一部分 訪問路徑是項目名/命名空間/actionname
        result  name  action處理方法返回值 type  跳轉結果類型 標籤體   指定跳轉的頁面
     包名重複-->
    <package name="xuantest" extends="struts-default">
        <!-- name 訪問路徑   class 存儲的位置   method是 調用Action中的訪問方法-->
        <action name="login" class="action.TestAction" method="login">
            <!--result是返回的跳轉界面-->
            <result name="success">/WEB-INF/jsp/login.jsp</result>
        </action>
        <action name="logincontroller" class="action.TestAction" method="loginconrtoller">
            <!--result是返回的跳轉界面-->
            <result name="success">/WEB-INF/jsp/success.jsp</result>
            <result name="fail">/WEB-INF/jsp/fail.jsp</result>
        </action>
    </package>
</struts>

6、連接數據庫（以MySQL爲例）在連接數據庫之前，需創建好數據庫

7、生成持久化類

8、完善項目結構，如下圖，代碼在圖下面，根據圖去決定文件放置的位置，也可以下載源碼

1、TestAction

package action;

import entity.TestEntity;
import service.TestService;
import utils.Singleton;

import java.util.Arrays;

/**
 * @author Xuan
 * @date 2019/9/21 9:57
 */
public class TestAction {
    //獲取前臺的id
    private Integer id;

    public Integer getId() {
        return id;
    }

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

    private TestService testService = (TestService) Singleton.GetApplicationContext().getBean("TestServiceImpl");
    /**
     * 進入登錄界面
     * @return
     */
    public String login(){
        return "success";
    }

    public String loginconrtoller(){
        System.out.println("來過");
        //根據id進行查詢
        TestEntity testEntity =  testService.findById(this.id);
        if (testEntity!=null){
            System.out.println("id是："+testEntity.getId()+"\t"+"name是："+testEntity.getName());
            return "success";
        }
        return "fail";
    }

}

2、TestDao

package dao;

import entity.TestEntity;

/**
 * Dao層
 * @author Xuan
 * @date 2019/9/21 9:46
 */
public interface TestDao {
    /**
     * 通過id獲取信息
     * @param id
     * @return
     */
    TestEntity findById(Integer id);
}

3、TestDaoImpl

package dao.impl;

import dao.TestDao;

import entity.TestEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.stereotype.Repository;

import javax.annotation.Resource;

/**
 * Dao層實現類
 * @author Xuan
 * @date 2019/9/21 9:48
 */
@Repository
public class TestDaoImpl implements TestDao {
    //提供Hibernate模板
    @Autowired
    @Resource
    private HibernateTemplate hibernateTemplate;

    public HibernateTemplate getHibernateTemplate() {
        return hibernateTemplate;
    }

    public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
        this.hibernateTemplate = hibernateTemplate;
    }

    @Override
    public TestEntity findById(Integer id) {
        return this.hibernateTemplate.get(TestEntity.class, id);
    }
}

4、TestEntity

package entity;

import javax.persistence.*;

/**
 * @author Xuan
 * @date 2019/9/21 9:40
 */
@Entity
@Table(name = "test", schema = "hibernate")
public class TestEntity {
    private int id;
    private String name;

    @Id
    @Column(name = "id")
    public int getId() {
        return id;
    }

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

    @Basic
    @Column(name = "name")
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        TestEntity that = (TestEntity) o;

        if (id != that.id) return false;
        if (name != null ? !name.equals(that.name) : that.name != null) return false;

        return true;
    }

    @Override
    public int hashCode() {
        int result = id;
        result = 31 * result + (name != null ? name.hashCode() : 0);
        return result;
    }
}

5、TestService

package service;

import entity.TestEntity;

/**
 * @author Xuan
 * @date 2019/9/21 9:51
 */
public interface TestService {
    /**
     * 通過id獲取信息
     * @param id
     * @return
     */
    TestEntity findById(Integer id);
}

6、TestServiceImpl

package service.impl;

import dao.impl.TestDaoImpl;
import entity.TestEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import service.TestService;

import javax.annotation.Resource;

/**
 * @author Xuan
 * @date 2019/9/21 9:51
 */
@Service("TestServiceImpl")
public class TestServiceImpl implements TestService {
    @Autowired
    @Resource
    private TestDaoImpl testDao;

    public TestDaoImpl getTestDao() {
        return testDao;
    }

    public void setTestDao(TestDaoImpl testDao) {
        this.testDao = testDao;
    }

    @Override
    public TestEntity findById(Integer id) {
        return testDao.findById(id);
    }
}

7、Singleton （這個在utils包下）

package utils;


import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * 單列雙檢索模式
 * @author Xuan
 *
 */
public class Singleton {
	/**
	 * 進行訪問控制
	 */
	private Singleton(){
		
	}
	private volatile static ApplicationContext applicationcontext;
	/**
	 * 得到ApplicationContext對象的方法
	 * @return
	 */
	public static ApplicationContext GetApplicationContext(){
		if (applicationcontext==null) {
			synchronized (Singleton.class) {
				if (applicationcontext==null) {
					applicationcontext = new ClassPathXmlApplicationContext("applicationContext.xml");
				}
			}
		}
		return applicationcontext;
	}
}

8、login.jsp
