一、SSH框架整合原理

1、Spring和Struts2整合就是将Action对象交给Spring容器进行创建

2、Spring和Hibernate整合就是将sessionFactory交给Spring来负责维护（session维护以及aop事物）

二、导包

先创建一个空的javaweb项目然后进行导包操作。

Hibernate

-hibernate-release-5.0.7.Final\lib\required

SSH框架整合

-hibernate-release-5.0.7.Final\lib\jpa（java persist api java的持久化规范-接口）

SSH框架整合

-数据库驱动包

SSH框架整合

Struts2

-struts-2.3.24\apps\struts2-blank\WEB-INF\lib

SSH框架整合

-struts-2.3.24\lib\struts2-spring-plugin-2.3.24.jar （struts整合spring插件包）注意:如果单用Struts2不使用Spring不要导入这个包，一旦导入那么Struts2在启动时就会寻找spring容器，找不到就会抛出异常。

SSH框架整合

Spring

-spring-framework-4.2.4.RELEASE\libs (四个基本包)

SSH框架整合

三、配置Spring容器

1、创建配置文件,并导入约束(4个)beans|context|aop|tx

SSH框架整合

</beans>

2、配置spring随项目启动

SSH框架整合

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>ssh_integrate</display-name>


<listener>
<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>

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>

</web-app>

阶段测试：启动项目确认sping整合是否成功。如果正常启动（控制台没有报错误信息）继续下面操作，如果不能正常启动重新执行以上步骤或排查问题。

四、配置Struts2

1、准备工作

-创建一个service接口

SSH框架整合

package com.ssh.service;

public interface UserService {
}

-创建一个实现类

SSH框架整合

package com.ssh.service.impl;

import com.ssh.service.UserService;
public class UserServiceImpl implements UserService{

}

-创建欢迎页

SSH框架整合

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
success
</body>

</html>

-创建Action,生成service的set方法

SSH框架整合

package com.ssh.action;
import com.opensymphony.xwork2.ActionSupport;
import com.ssh.service.UserService;

public class UserAction extends ActionSupport {
UserService userService;
public String login(){
System.out.println(userService);
return SUCCESS;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
}

2、配置struts2主配置文件

-创建struts2配置文件

SSH框架整合

<?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>
<package name="ssh" namespace="/" extends="struts-default">
<action name="UserAction_*" class="com.ssh.action.UserAction" method="{1}">
<result name="success">/</result>
</action>
</package>

</struts>

-配置struts2核心过滤器到web.xml

SSH框架整合

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>ssh_integrate</display-name>


<listener>
<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>


<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>

</web-app>

阶段测试：启动项目确认struts2整合是否成功。如果正常启动（控制台没有报错误信息）继续下面操作，如果不能正常启动重新执行以上步骤或排查问题。

五、struts2与spring整合

-导包（之前已经导入过了）

SSH框架整合

-配置整合方案:spring负责创建action以及组装.

SSH框架整合

-配置常量

SSH框架整合

<?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>

<constant name="struts.objectFactory" value="spring"></constant>


<package name="ssh" namespace="/" extends="struts-default">
<action name="UserAction_*" class="userAction" method="{1}">
<result name="success">/success.jsp</result>
</action>
</package>

</struts>

阶段测试：启动项目测试spring和struts2整合是否成功。如果正常启动,访问http://localhost:8080/ssh_integrate/UserAction_login能显示页面,且控制台打印service地址则整合成功，继续下面操作，否则重新执行以上步骤或排查问题。

SSH框架整合

六、单独配置hibernate

-创建数据库和表

SSH框架整合

CREATE TABLE `user` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

-创建实体类

SSH框架整合

package com.ssh.bean;

public class User {
/*
*
CREATE TABLE `user` (
`id` int(10) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
*/
private Integer id;
private String username;
private String password;

public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

-创建ORM元数据

SSH框架整合

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.ssh.bean" >
<class name="User" table="user" >
<id name="id" >
<generator class="native"></generator>
</id>
<property name="username" ></property>
<property name="password" ></property>
</class>

</hibernate-mapping>

-配置hibernate主配置文件

SSH框架整合

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>

<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>

<property name="hibernate.connection.url">jdbc:mysql:///ssh</property>

<property name="hibernate.connection.username">root</property>

<property name="hibernate.connection.password">mysql</property>

<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>


<property name="hibernate.show_sql">true</property>

<property name="hibernate.format_sql">true</property>

<property name="hibernate.hbm2ddl.auto">update</property>
<mapping resource="com/ssh/bean/User.hbm.xml" />
</session-factory>

</hibernate-configuration>

阶段测试：

编写hibernate测试类

SSH框架整合

package com.ssh.test;

import org.hibernate.Session;

import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;
import com.ssh.bean.User;

//测试hibernate框架
public class HibernateTest {

@Test
public void fun1() {
Configuration configuration = new Configuration().configure();

SessionFactory sessionFactory = configuration.buildSessionFactory();

Session session = sessionFactory.openSession();

Transaction transaction = session.beginTransaction();

//========================================================
User user = new User();
user.setUsername("username");
user.setPassword("password");
session.save(user);
transaction.commit();
session.close();

sessionFactory.close();
}

}

执行成功且数据库保存数据成功则表示成功

七、spring整合hibernate

1、整合原理

将sessionFactory对象交给spring容器管理

2、在spring中配置sessionFactory

SSH框架整合

</beans>

阶段测试：执行以下测试方法测试保存数据是否成功

package com.ssh.test;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.ssh.bean.User;

//测试hibernate框架
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class HibernateTest {

@Resource(name="sessionFactory")
private SessionFactory sessionFactory ;

// @Test
// public void fun1() {
// Configuration configuration = new Configuration().configure();
//
// SessionFactory sessionFactory = configuration.buildSessionFactory();
//
// Session session = sessionFactory.openSession();
//
// Transaction transaction = session.beginTransaction();
//
// //========================================================
// User user = new User();
// user.setUsername("username");
// user.setPassword("password");
// session.save(user);
// transaction.commit();
// session.close();
//
// sessionFactory.close();
// }

@Test
//测试spring管理sessionFactory
public void fun2(){
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
//-------------------------------------------------
User user = new User();
user.setPassword("22");
user.setUsername("11");
session.save(user);

//-------------------------------------------------
tx.commit();

session.close();

}
}

八、spring整合c3p0连接池

1、配置db.properties

SSH框架整合

jdbc.jdbcUrl=jdbc:mysql:///ssh
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root

jdbc.password=mysql

2、引入连接池到spring中并将连接池注入给SessionFactory

SSH框架整合

<?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:aop="http://www.springframework.org/schema/aop"
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/aop
http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-4.2.xsd ">


<context:property-placeholder location="classpath:db.properties" />


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


<bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

<property name="dataSource" ref="dataSource" ></property>


<property name="hibernateProperties">
<props>






<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>



<prop key="hibernate.show_sql">true</prop>

<prop key="hibernate.format_sql">true</prop>

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

</props>
</property>


<property name="mappingDirectoryLocations" value="classpath:com/ssh/bean" ></property>
</bean>



<bean name="userAction" class="com.ssh.action.UserAction" scope="prototype">
<property name="userService" ref="userService"></property>
</bean>


<bean name="userService" class="com.ssh.service.impl.UserServiceImpl"></bean>

</beans>

阶段测试：再次执行上一步的测试方法测试保存数据是否成功

九、spring整合hibernate环境操作数据库

1、类创建Dao接口和实现类（实现类需要继承HibernateDaoSupport）

-创建Dao接口

SSH框架整合

package com.ssh.dao;

import com.ssh.bean.User;

public interface UserDao {
public User getByUserName(String username);

}

-创建Dao实现类

SSH框架整合

package com.ssh.dao.impl;

import java.util.List;

import org.hibernate.criterion.DetachedCriteria;
import org.hibernate.criterion.Restrictions;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

import com.ssh.bean.User;
import com.ssh.dao.UserDao;

public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

@Override
public User getByUserName(final String username) {
//HQL
/*return getHibernateTemplate().execute(new HibernateCallback<User>() {
@Override
public User doInHibernate(Session session) throws HibernateException {
String hql = "from User where username = ? ";
Query query = session.createQuery(hql);
query.setParameter(0, username);
User user = (User) query.uniqueResult();
return user;
}
});*/
//Criteria
DetachedCriteria dc = DetachedCriteria.forClass(User.class);

dc.add(Restrictions.eq("username", username));

List<User> list = (List<User>) getHibernateTemplate().findByCriteria(dc);

if(list != null && list.size()>0){
return list.get(0);
}else{
return null;
}
}

}

2、spring中配置dao

SSH框架整合

</beans>

阶段测试：执行测试方法，如果能查询到数据表示成功

package com.ssh.test;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.ssh.bean.User;
import com.ssh.dao.UserDao;

//测试hibernate框架
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class HibernateTest {

@Resource(name="sessionFactory")
private SessionFactory sessionFactory ;

// @Test
// public void fun1() {
// Configuration configuration = new Configuration().configure();
//
// SessionFactory sessionFactory = configuration.buildSessionFactory();
//
// Session session = sessionFactory.openSession();
//
// Transaction transaction = session.beginTransaction();
//
// //========================================================
// User user = new User();
// user.setUsername("username");
// user.setPassword("password");
// session.save(user);
// transaction.commit();
// session.close();
//
// sessionFactory.close();
// }
//
// @Test
// //测试spring管理sessionFactory
// public void fun2(){
// Session session = sessionFactory.openSession();
// Transaction tx = session.beginTransaction();
// //-------------------------------------------------
// User user = new User();
// user.setPassword("55");
// user.setUsername("66");
// session.save(user);
//
// //-------------------------------------------------
// tx.commit();
//
// session.close();
//
// }

@Resource(name="userDao")
private UserDao ud;

@Test
//测试Dao Hibernate模板
public void fun3(){

User u = ud.getByUserName("username");

System.out.println(u);
}

}

十、spring的AOP事务
