struts2+hibernate3.2+spring2.0整合篇（三）

      在上篇文章中，我们已经将各层之间相关的类创建完毕，这篇我们主要讲解如何通过spring管理类之间的依赖关系。

   步骤八：通过spring管理类之间的依赖关系。

   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: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">

	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
		<property name="url" value="jdbc:mysql://localhost:3306/mytest"></property>
		<property name="username" value="root"></property>
		<property name="password" value="root"></property>
		<property name="maxActive" value="100"></property>
		<property name="maxIdle" value="30"></property>
		<property name="maxWait" value="500"></property>
		<property name="defaultAutoCommit" value="true"></property>
	</bean>

	<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.MySQLDialect</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
		<property name="mappingResources">
			<list>
				<value>com/tgb/bean/User.hbm.xml</value>
			</list>
		</property>
	</bean>

	<bean id="userDao" class="com.tgb.dao.impl.UserDAOImpl" scope="singleton">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>

	<bean id="userService" class="com.tgb.service.impl.UserServiceImpl">
		<property name="userDao">
			<ref bean="userDao" />
		</property>
	</bean>

	<bean id="saveUserAction" class="com.tgb.action.user.SaveUserAction">
		<property name="userService">
			<ref bean="userService" />
		</property>
	</bean>

	<bean id="listUserAction" class="com.tgb.action.user.ListUserAction">
		<property name="userService">
			<ref bean="userService" />
		</property>
	</bean>
</beans>

           我们可以通过Spring Explorer查看在applicationContext.xml中配置的类之间的依赖关系，效果图如下：

  

    步骤九：通过web.xml中管理jsp页面的显示。

    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">

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

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

	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>

	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>
</web-app>

       到此，我们已经完成struts2+hibernate3.2+spring2.0整合的全部工作，把项目发布到Tomcat上，看看运行效果吧。
