SSH的整合

我发表下SSH的整合,为了我能更好地记住。

struts2和hibernate的配置我这里就不多说了,先把两个有关的东西说下。一个是所有的包。struts2+hibernate3+spring2.5我包准备放上去给大家下载。

放在的我百度云盘里面

闲话不说:开始。

先是struts2和hibernate的配置

web.xml:

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- structs2的配置 --> <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> </web-app>

 然后在src下添加一个struts.xml:

<?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> </struts>

 然后在src下添加一个hibernate.cfg.xml:(这是一些数据库的配置)

<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <!-- Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <session-factory> <property name="connection.username">sa</property> <property name="connection.url"> jdbc:jtds:sqlserver://localhost:1433;DatabaseName=LQQ </property> <property name="dialect"> org.hibernate.dialect.SQLServerDialect </property> <!--<property name="myeclipse.connection.profile"> LoginSystem </property> --> <property name="connection.password">sa</property> <property name="connection.driver_class"> net.sourceforge.jtds.jdbc.Driver </property> <property name="show_sql">true</property> <!-- POJO 类映射配置--> <mapping resource="sedion/xq/ORM/Stuinfo.hbm.xml" /> </session-factory> </hibernate-configuration>

重点讲Spring:1. src下面新建applicationContext.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:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd"> <!-- 这是个例子待会会用到 可以先不要 --> <bean id="TUser_id" class="test.TUser"> <property name="username" value=""></property> <property name="allname" value=""></property> <property name="address" value="温州市"></property> </bean> </beans>

 然后在web-xml:

<context-param> <param-name>contextConfigLocation</param-name> <!--spring 的配置文件加载路径--> <param-value>classpath:applicationContext.xml</param-value> </context-param>

 

2.Spring基本配置完毕

下面我们测试下:src建个test包

建两个类User和SpringTest类:

 

public class User implements java.io.Serializable { /** * */ private static final long serialVersionUID = 1L; private String username; private String allname; private String address; public String getUsername() { return this.username; } public void setUsername(String username) { this.username = username; } public String getAllname() { return this.allname; } public void setAllname(String allname) { this.allname = allname; } public String getAddress() { return this.address; } public void setAddress(String address) { this.address = address; }

 

 

public class SpringTest { public static void main(String[] args) { // 加载spring配置文件,初始化IoC容器 ApplicationContext ac = new ClassPathXmlApplicationContext( "applicationContext.xml"); // 从容器 接管Bean TUser user = (TUser) ac.getBean("TUser_id"); // 输出欢迎信息 System.out.println("Hello:" + user.getUsername() + ";u is in " + user.getAddress() + " ; and u is " + user.getAllname()); } }

 

别忘了:applicationContext.xml中配置一个bean,在xml中增加如下代码:

 

<!-- 这是个例子待会会用到 可以先不要 -->   <bean id="TUser_id" class="test.TUser"> <property name="username" value="你"></property> <property name="allname" value="李"></property> <property name="address" value="温州市"></property> </bean>

 

 

 

运行main方法后

控制台出现:Hello:你;u is in 温州市 ; and u is  李

下面开始整合

整合struts2

  1.整合struts2配置web.xml文件。在web.xml中加入以下代码:

 

<!-- Spring与Struts的整合其实就是把Struts的Action类交给Spring来管理 --> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener>

 

 2.举个例子:

  把strutsaction交给spring:

  先把 

<action name="login" class="test.LoginAction ">

 改为

<action name="login" class="loginAction_id">

 

 

然后在

applicationContext.xml中增加如下代码:

 

<bean id="loginAction_id" class="test.action.LoginAction" scope="prototype"> </bean>

 

 

整合Hibernate

 Spring整合Hibernate主要是对hibernateSession进行管理,包含Session的创建、提交、关闭的整个生命周期。Spring对事务的管理应用了AOP的技术

1)        配置sessionFactoryspring来创建Session

我们原来是用HibernateSessionFactory.java来创建Session的,现在删除即可,交给Spring创建。(这样就spring来整合hibernate来创建session)

这里,创建了一个Session工厂类的Bean,其ID为“sessionFactory”.

 

applicationContext.xml中增加如下代码:

 

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

 

还有个例子上的配置:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list>      <value>sedion/xq/bean/User.hbm.xml</value><!--这里是将映射文件加载--> </list> </property> </bean>

 

2.

然后DAO层匹配一个session工厂,<ref bean="sessionFactory"/>这个sessionFactory是指session工厂的ID。

 

<bean id="userDao" class="sedion.xq.dao.iml.UserDAOImpl" scope="singleton"> <property name="sessionFactory"> <ref bean="sessionFactory" /> </property> </bean>

 

 3.service层注入DAO层

<bean id="userService" class="sedion.xq.sevice.iml.UserServiceImpl"> <property name="userDAO" ref="userDao"></property> </bean>

 然后就是各个action注入service层:(随便写个)

<bean id="saveUesrAction" class="sedion.xq.action.user.SaveUserAction" scope="prototype"> <property name="userService" ref="userService"></property> </bean>

 整合就这样好
