            </resource>
        </resources>
    </build>
</project>

5、在Resources文件目录下创建如下配置文件

1、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
						http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
						http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">
    <!-- 加载数据库连接信息配置文件 -->
    <context:property-placeholder location="classpath:db.properties" />
    <!--druid连接池  -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${druid.driver}"/>
        <property name="url" value="${druid.url}"/>
        <property name="username" value="${druid.username}"/>
        <property name="password" value="${druid.password}"/>
    </bean>
    <context:component-scan base-package="xuan.dao.*,xuan.service.*"/>
    <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>

                <!--格式化输出sql语句-->
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.use_sql_comments">false</prop>
            </props>
        </property>
        <!-- 自动扫描实体 -->
        <property name="packagesToScan"  value="xuan.entity" />
    </bean>
    <!-- 配置 HibernateTemplate 对象 -->
    <bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate">
        <!-- 注入 SessionFactory 对象 -->
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <!-- 用注解来实现事务管理 -->
    <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    <tx:annotation-driven transaction-manager="txManager"/>
</beans>

2、springmvc.xml

<?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:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       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/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!-- SpringMVC使用<mvc:annotation-driven>自动加载RequestMappingHandlerMapping和RequestMappingHandlerAdapter -->
    <mvc:annotation-driven />
    <!-- 启动注解 -->
    <!-- 配置扫描注解  @Controller -->
    <context:component-scan base-package="xuan.controller"/>
    <!-- 配置静态资源映射 -->
    <!--
    <mvc:resources location="/js/" mapping="/js/**"/>
    <mvc:resources location="/css/" mapping="/css/**"/>
     <mvc:resources location="/imgs/" mapping="/imgs/**"/>
     <mvc:resources location="/font/" mapping="/font/**"/>
     -->

    <!-- 配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 配置逻辑视图的前缀 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
        <!-- 配置逻辑视图的后缀 -->
        <property name="suffix" value=".jsp" />

    </bean>
</beans>

3、db.properties

druid.driver=com.mysql.jdbc.Driver
druid.url=jdbc:mysql://localhost:3306/xuan?characterEncoding=utf-8
druid.username=root
druid.password=root

6、连接数据库（以MySQL为例）在连接数据库之前，需创建好数据库

7、生成持久化类

8、完善项目结构，如下图，代码在图下面，根据图去决定文件放置的位置，也可以下载源码

1、TestController

package xuan.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import xuan.entity.TestEntity;
import xuan.service.TestService;
import xuan.utils.Singleton;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

/**
 * 控制层
 * @author Xuan
 * @date 2019/9/17 17:53
 */
@Controller
public class TestController {
    private TestService testService = (TestService) Singleton.GetApplicationContext().getBean("TestServiceImpl");

    /**
     * 获取所有数据并且返回到index.jsp页面
     * @param request
     * @return
     */
    @RequestMapping("/GetAll")
    public String test(HttpServletRequest request){
        System.out.println("来过");
        List<TestEntity> list = testService.GetAll();
        for (TestEntity arr:list) {
            System.out.println(arr.getId());
        }
        request.getSession().setAttribute("xuanlist",list);
        return "show";
    }
}

2、TestDaoImpl

package xuan.dao.impl;

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

import javax.annotation.Resource;
import java.util.List;

/**
 * @author Xuan
 * @date 2019/10/2 3:23
 */
@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 List<TestEntity> GetAll() {
        return this.hibernateTemplate.loadAll(TestEntity.class);
    }
}

3、TestDao

package xuan.dao;

import xuan.entity.TestEntity;

import java.util.List;

/**
 * 映射类接口
 * @author Xuan
 * @date 2019/9/17 17:51
 */
public interface TestDao {
    /**
     * 查询所有列表
     * @return
     */
    List<TestEntity> GetAll();
}

4、TestEntity

package xuan.entity;

import javax.persistence.*;

/**
 * @author Xuan
 * @date 2019/10/2 4:35
 */
@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、TestServiceImpl

package xuan.service.impl;

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

import javax.annotation.Resource;
import java.util.List;

/**
 * Service服务层
 * @author Xuan
 * @date 2019/9/17 17:54
 */
@Service("TestServiceImpl")
public class TestServiceImpl implements TestService {

    @Autowired
    @Resource
    private TestDao testmapper;

    public TestDao getTestmapper() {
        return testmapper;
    }

    public void setTestmapper(TestDao testmapper) {
        this.testmapper = testmapper;
    }

    @Override
    public List<TestEntity> GetAll() {
        return testmapper.GetAll();
    }
}

6、TestService

package xuan.service;

import xuan.entity.TestEntity;

import java.util.List;

/**
 * @author Xuan
 * @date 2019/9/17 17:53
 */
public interface TestService {
    /**
     * 查询所有列表
     * @return
     */
    List<TestEntity> GetAll();
}

7、Singleton

package xuan.utils;


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

/**
 * 单列双检索模式
 * @author Xuan
 *
 */
public class Singleton {
	/**
	 * 进行访问控制
	 */
	private Singleton(){
		
	}
	private volatile static ApplicationContext applicationcontext;
	/**
	 * 得到ApplicationContext对象的方法
	 * @return
	 */
	public static ApplicationContext GetApplicationContext(){
		if (applicationcontext==null) {
			synchronized (Singleton.class) {
				if (applicationcontext==null) {
					applicationcontext = new ClassPathXmlApplicationContext("applicationContext.xml");
				}
			}
		}
		return applicationcontext;
