1、创建项目
2、在main文件夹下新建一个java文件夹,设置为sourceRoot类型
3、在main文件夹下新建一个Resources文件夹,设置为Resources Root类型
4、导入pom文件的相关依赖

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"

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="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="hibernateProperties">

</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>

</props>
</property>
<!-- 自动扫描实体 -->

</bean>
<!-- 配置 HibernateTemplate 对象 -->

</bean>

<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/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 -->

<!-- 配置视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/WEB-INF/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;
}
}
8、show.jsp
<%@ page import="java.util.List" %>
<%@ page import="xuan.entity.TestEntity" %><%--

<body>
<%
List<TestEntity> list = (List<TestEntity>) request.getSession().getAttribute("xuanlist");
for (TestEntity arr :list) {
response.getWriter().println("ID是"+arr.getId()+"姓名是:"+arr.getName());
}
%>
<%-- <c:forEach var="r" items="${xuanlist}" varStatus="vs">--%>
<%-- ID是:${r}--%>
<%-- 姓名是:${r.name}--%>
<%-- </c:forEach>--%>
</body>
</html>
9、配置web.xml
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>

</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
10、配置tomcat
11、启动tomcat,访问地址 http://localhost:1314/springspringmvchibernate_war/GetAll
1、我的数据库数据
2、访问效果
