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="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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/context/spring-context.xsd">

<!-- 数据源连接池 -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="hibernateProperties">
<props>

</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
#连接池中保留的最小连接数
jdbc.minPoolSize=1
#连接池中保留的最大连接数
jdbc.maxPoolSize=20
#初始化连接数
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>
<!-- 开启使用开发模式，详细错误提示 -->
<constant name="struts.devMode" value="true" />
<!-- 将对象交给spring管理 -->
<constant name="struts.objectFactory" value="spring" />

<constant name="struts.i18n.encoding" value="UTF-8" />
<!-- 指定每次请求到达，重新加载资源文件 -->

<!-- 浏览器是否缓存静态内容，生产环境下需要设置为true -->
<constant name="struts.serve.static.browserCache" value="true" />
<!-- 开启动态方法调用 -->
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<!--package包作用是管理action 通常一个业务模块 用一个包 在struts中包一定要继承struts-default包
还有一个namespace 作为路径的一部分 访问路径是项目名/命名空间/actionname
result name action处理方法返回值 type 跳转结果类型 标签体 指定跳转的页面
包名重复-->
<package name="xuantest" extends="struts-default">
<!-- name 访问路径 class 存储的位置 method是 调用Action中的访问方法-->
<action name="login" class="action.TestAction" method="login">
<!--result是返回的跳转界面-->
<result name="success">/WEB-INF/jsp/login.jsp</result>
</action>
<action name="logincontroller" class="action.TestAction" method="loginconrtoller">
<!--result是返回的跳转界面-->
<result name="success">/WEB-INF/jsp/success.jsp</result>
<result name="fail">/WEB-INF/jsp/fail.jsp</result>
</action>
</package>
</struts>
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、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 {
//获取前台的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");
/**
* 进入登录界面
* @return
*/
public String login(){
return "success";
}
public String loginconrtoller(){
System.out.println("来过");
//根据id进行查询
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层
* @author Xuan
* @date 2019/9/21 9:46
*/
public interface TestDao {
/**
* 通过id获取信息
* @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层实现类
* @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 {
/**
* 通过id获取信息
* @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 （这个在utils包下）
package 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、login.jsp

11、web.xml （这里去修改一下web.xml就行了）
<!DOCTYPE web-app PUBLIC

"http://java.sun.com/dtd/web-app_2_3.dtd" >

<!-- 上下文监听器 -->

9、配置tomcat
10、启动tomcat，访问地址 http://localhost:8080/ssh_war/login
