Sring与Struts整和目的，让struts2的action由容器管理，从容器里拿到对象
Spring与Hibernate整和目的
管理sessionFactory实例(只需要一个，单例)
Spring IOC容器 -->管理对象，管理单例对象，装配扫描注入对象 。。
AOP面向切面编程---> 管理实务。。
struts2配置
1.web.xml
<span style="font-size:18px;"> <!-- 配置Struts2的核心的过滤器 --> <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></span>
2.struts.xml
<span style="font-size:18px;"><?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 配置为开发模式 -->
<constant name="struts.devMode" value="true" />
<!-- 拓展名配置为action -->
<constant name="struts.action.extension" value="action" />
<!-- 将主题配置为simple -->
<constant name="struts.ui.theme" value="simple" />
<package name="default" namespace="/" extends="struts-default">
<!-- 配置测试struts的action,未于Spring整合,class属性写类的全名 -->
<action name="test" class="cn.linyi.oa.test.TestAction" method="execute">
<result name="success">/test.jsp</result>
</action>
</package>
</struts></span>
3.Jar包
4.struts2测试（jsp页面+Action类）
test.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Struts2测试页面</title>
<body>
struts2配置成功 !<br>
</body>
</html>
cn.linyi.oa.test.TestAction
<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></span><pre name="code" class="html">package cn.linyi.oa.test;
import com.opensymphony.xwork2.ActionSupport;
public class TestAction extends ActionSupport {
@Override
public String execute()throws Exception{
System.out.println("-->TestAction.execute()");
return "success";
}
}
URL输入http://localhost:8080/项目名/test.action(后缀名已设定，必须添加)
Spring配置
1.applicationContext.xml / bean.xml文件
<?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: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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <!-- 自动扫描与装配bean --> <context:component-scan base-package="cn.linyi.oa"></context:component-scan> </beans>
2.对Action类修改，添加注解注入
package cn.linyi.oa.test;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import com.opensymphony.xwork2.ActionSupport;
<span style="color:#ff0000;">@Component
@Controller
@Service
@Repository</span>
public class TestAction extends ActionSupport {
@Override
public String execute()throws Exception{
System.out.println("-->TestAction.execute()");
return "success";
}
}
3.spring测试类
package cn.linyi.oa.test;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringTest {
private ApplicationContext ac =new ClassPathXmlApplicationContext("applicationContext.xml");
@Test
public void testBean() throws Exception{
TestAction testAction= (TestAction)ac.getBean("testAction");
/*虽然spring定义了对cn.linyi.oa包的自动扫描与装配，但若TestAction没有注解注入，会导致输出testAction对象出错*/
System.out.println("testAction:"+testAction);
}
}
4.Spring Jar包+Junit4测试jar包
Struts与Spring整合
1.web.xml
<!-- 配置Spring的用于初始化容器对象的监听器 --> <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>
2.修改struts.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<!-- 配置为开发模式 -->
<constant name="struts.devMode" value="true" />
<!-- 拓展名配置为action -->
<constant name="struts.action.extension" value="action" />
<!-- 将主题配置为simple -->
<constant name="struts.ui.theme" value="simple" />
<package name="default" namespace="/" extends="struts-default">
<!-- 配置测试struts的action,未于Spring整合,class属性写类的全名 -->
<!-- 当striys2与spring整合后，class属性的属性值写bean的名称 -->
<action name="test" <span style="color:#ff0000;">class="testAction"</span> method="execute">
<result name="success">/test.jsp</result>
</action>
</package>
</struts>
3.applicationContext.xml文件如上，不修改
4.SpringTest.java类如上，不修改
5.整合struts-spring-plugin-2.1.8.1.jar
URL输入http://localhost:8080/项目名/test.action
Spring整合Hibernate
1.applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

</beans>
2.Hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

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

-->
<!-- 2，其他配置 (自动建表)(显示sql语句)(配置二级缓存)-->
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">update</property>
<!-- 3，导入映射文件 (空值需屏蔽掉，否则出错)-->
<!--

-->
</session-factory>
</hibernate-configuration>3.测试类（测试sessionFactory）
package cn.linyi.oa.test;
import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringTest {
private ApplicationContext ac =new ClassPathXmlApplicationContext("applicationContext.xml");
@Test
public void testBean() throws Exception{
TestAction testAction= (TestAction)ac.getBean("testAction");
/*虽然spring定义了对cn.linyi.oa包的自动扫描与装配，但若TestAction没有注解注入，会导致输出testAction对象出错*/
System.out.println("testAction:"+testAction);
}
<span style="color:#ff0000;"> // 测试SessionFactory
@Test
public void testSessionFactory() throws Exception {
SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");
System.out.println("sessionFactory:"+sessionFactory);
}
</span>
}
4.web.xml添加spring的监听器如上
测试事务
package cn.linyi.oa.test;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import cn.linyi.oa.domain.User;
//想要注入的话，当前对象必须在容器里
@Service
public class TestService {
//通过sessionFactory得到session
@Resource
private SessionFactory sessionFactory;
@Transactional
public void saveTwoUsers() {
Session session=sessionFactory.getCurrentSession();
session.save(new User());
//int a=1/0;//控制抛异常，会回滚
session.save(new User());
}
}测试时，自动建表（在数据库建好的情况下）
package cn.linyi.oa.test;
import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringTest {
private ApplicationContext ac =new ClassPathXmlApplicationContext("applicationContext.xml");
// 测试spring配置是否成功
@Test
public void testBean() throws Exception{
TestAction testAction= (TestAction)ac.getBean("testAction");
/*虽然spring定义了对cn.linyi.oa包的自动扫描与装配，但若TestAction没有注解注入，会导致输出testAction对象出错*/
System.out.println("testAction:"+testAction);
}
// 测试SessionFactory(测试Spring与Hibernate整合情况)
@Test
public void testSessionFactory() throws Exception {
SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");
System.out.println("sessionFactory:"+sessionFactory);
}
<span style="color:#ff0000;"> //测试事务(测试Spring与Hibernate整合情况)
@Test
public void testTransaction() throws Exception{
TestService testService=(TestService) ac.getBean("testService");
testService.saveTwoUsers();
}</span>
}
