[编程语言]SSH框架整合demo

Struts、Spring、Hibernate整合

一、创建web工程,搭建Struts框架开发环境:


这里只导入了项目中所需要的重要的jar包,以后根据业务要求继续导入相关的包。
  1. 步骤1::导入struts框架所需的jar包
  2. 步骤2:在web.xml中配置struts2.0主过滤器
  3. 步骤3:导入struts.xml配置文件

	<constant name="struts.action.extension" value="action"/>
    <package name="default" namespace="/" extends="struts-default">

    </package>
    
</struts>

二、搭建Hibernate开发环境:


创建数据库:

这里只导入了项目中所需要的重要的jar包,以后根据业务要求继续导入相关的包。

hibernate.cfg.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC

	"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.xbmu.oa.domain">
	
</hibernate-mapping>

三、搭建Spring开发环境:


这里只导入了项目中所需要的重要的jar包,以后根据业务要求继续导入相关的包。
[img]http://img.blog.csdn.net/20160403200720523?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
applicationContext.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: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.xbmu.oa"></context:component-scan>



</beans>
以上已经将Struts、Spring、Hibernate开发所需要的jar包及其配置文件已经配置到web工程中了。
接下来,我们两两整合在一起。

四、Spring与Hibernate整合:


让Spring来管理SessionFactory和事务。

		<!--最大空闲时间,1800秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->
		<property name="maxIdleTime" value="1800"></property>
	</bean>

	<!-- 配置SessionFactory -->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource"></property>
		<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
	</bean>


	<!-- 配置声明式的事务管理(采用基于注解的方式) -->
	<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<tx:annotation-driven transaction-manager="transactionManager" />

</beans>


jdbc.properties

jdbcUrl		= jdbc:mysql:///xbmuoa
driverClass	= com.mysql.jdbc.Driver
username	= root
password	= root
SpringTest.java
package cn.xbmu.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SessionFactory
	@Test
	public void testSessionFactory(){
		SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");
		System.out.println(sessionFactory);
	}
}
使用Junit测试,结果:
[img]http://img.blog.csdn.net/20160403204509428?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
启动tomcat没有报错,说明以上环境的搭建都完全正确,并进行测试,也没有报错。
User.java
package cn.xbmu.oa.domain;

public class User {
	private Long id;
	private String name;
	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
}
User.hbm.xml
<?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="cn.xbmu.oa.domain">
	<class name="User">
		<id name="id">
			<generator class="native"/>
		</id>
		<property name="name"/>
	</class>
</hibernate-mapping>

记得在hibernate.cfg.xml文件中引入映射文件。
TestService.java
package cn.xbmu.oa.test;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import cn.xbmu.oa.domain.User;
@Service("testService")
public class TestService {
	@Resource
	private SessionFactory sessionFactory;
	@Transactional
	public void saveTwoUser(){
		Session currentSession = sessionFactory.getCurrentSession();
		currentSession.save(new User());
		int i = 1 / 0;//这里会抛出异常
		currentSession.save(new User());
	}
}
SpringTest.java
package cn.xbmu.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SessionFactory
	@Test
	public void testSessionFactory(){
		SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");
		System.out.println(sessionFactory);
	}
	//测试事务
	@Test
	public void testTransaction(){
		TestService testService = (TestService) ac.getBean("testService");
		testService.saveTwoUser();
	}
}
测试事务,报错,因为在 int i = 1 / 0这里发生了异常。

查询数据库xbmuoa中的表,没有数据
[img]http://img.blog.csdn.net/20160403205320807?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
我们注释掉  int i = 1 / 0;这句代码,重新测试,成功。
[img]http://img.blog.csdn.net/20160403205625933?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
查询user表,里面已经有了保存的数据
[img]http://img.blog.csdn.net/20160403205723246?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
我们,继续打开抛异常的语句,再测试;再注释抛异常的代码,再测试。查看表中的数据,发现了事务回滚了。
[img]http://img.blog.csdn.net/20160403210624483?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
到此为止,我们顺利的将Spring与Hibernate整合在一起了。并测试了SessionFactory与事务,都正常。

五、Spring与Struts整合:


为了说明白,我们在整合之前写个Action,整合之后写个Action,看看他们之间的区别:

整合之前:


TestAction.java
package cn.xbmu.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";
	}
}
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>
	<!-- 配置为开发模式 -->
    <constant name="struts.devMode" value="true" />
    <!-- 配置扩展名为action -->
	<constant name="struts.action.extension" value="action"/>
    <package name="default" namespace="/" extends="struts-default">
    	<!-- 测试用的action -->
		<action name="test" class="cn.xbmu.oa.test.TestAction">
			<result name="success">/test.jsp</result>
		</action>
    </package>
    
</struts>
test.jsp

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

  <head>
  </head>
  <body>
  	Struts2.0添加成功<br/>
  </body>
</html>
运行:

整合之后:


导入jar包,已经完成了整合
[img]http://img.blog.csdn.net/20160403214841062?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQv/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center
TestAction.java
package cn.xbmu.oa.test;

import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.opensymphony.xwork2.ActionSupport;
@Controller
@Scope("prototype")
public class TestAction extends ActionSupport {
	
	@Override
	public String execute() throws Exception {
		System.out.println("---------->TestAction execute()");
		return "success";
	}
}
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>

    <!-- 配置扩展名为action -->
	<constant name="struts.action.extension" value="action"/>
    <package name="default" namespace="/" extends="struts-default">
    	<!-- 测试用的action,当与Spring整合后,class属性写的就是bean的名称-->
		<action name="test" class="testAction">
			<result name="success">/test.jsp</result>
		</action>
    </package>
    
</struts>
在浏览器上运行:http://localhost:8080/xbmuoa/test.action
发现,在控制台上报错,信息如下:
严重: ********** FATAL ERROR STARTING UP STRUTS-SPRING INTEGRATION **********
