（四）配置之SSH2整合

之前讲的内容已经或多或少和整合挂上钩了，当然，之前的内容就不过多的重复。现在在把这个钩真正的挂上。废话不多说。GO！
struts.xml的配置：

<?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>
    <!-- 把Struts2交给Spring管理 -->
    <constant name="struts.objectFactory" value="spring"></constant>//必须的
    <package name="xxx" extends="struts-default" namespace="">
        <action name="LoginAc" class="bean的id">//这里的class不是全路径，只是Spring的Bean组件而已了。例如有个Bean的id为adminLogin,则class="adminLogin"。
            <result name="success">/index.jsp</result>
        </action>
    </package>
</struts>

applicationContext.xml的配置：

<?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: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-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/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
   <context:component-scan base-package="com.lrl"></context:component-scan>
   <!--数据源的定义-->//数据源需commons-pool.jar、commons-dbcp.jar
   <bean id="bbsDateSource" class="org.apache.commons.dbcp.BasicDataSource">
	<property name="driverClassName" value="com.mysql.jdbc.Driver">
        </property>                    
	<property name="url" value="jdbc:mysql://localhost:3306/bbspro">
        </property>
	<property name="username" value="root"></property>
	<property name="password" value="123"></property>
	</bean>
   <!--sessionFactory的定义-->
<bean id="sessionFactory"		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource">
	<ref bean="bbsDateSource" />
    </property>
    <property name="hibernateProperties">
	<props>
	<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
	<prop key="hibernate.hbm2ddl.auto">update</prop>
	<prop key="hibernate.show_sql">true</prop>
	</props>
    </property>
    <property name="packagesToScan">
	<value>com.bbs.entity</value>//这里写Entity的包路径,也就是实体类的包路径
    </property>
</bean>
<bean id="testDao" class="com.junit.test.TestDao">
		<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
</beans>

之前用的是Annotation的Entity，代码如上，下面的代码可以配置使用xxx.hbm.xml的SessionFactory。

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
   <property name="dataSource">
	<ref bean="mySqlDateSource" />
   </property>
   <property name="hibernateProperties">
	<props>
	<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
	<prop key="hibernate.hbm2ddl.auto">update</prop>
	<prop key="hibernate.show_sql">true</prop>
	</props>
   </property>
   <property name="mappingResources">
	<list>
		<value>com/lrl/entity/User.hbm.xml</value>//这里是xml
	</list>
   </property>
</bean>

web.xml的配置：

<?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">
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
  	<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>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationContext.xml</param-value>
	</context-param>
//字符编码
	<filter>
		<filter-name>encoding</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encoding</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

</web-app>

基本配置就如此而已。如果用MyEclipse开发。把JavaEE5.0的jar拷出，导入lib里。避免部分冲突。详情本博客的其他文章。。
总结：
（1）主要开发过程：applicationContext.xml+struts.xml+web.xml
（2）spring管理Hibernate，那么hibernate.cfg.xml就不需要了，在applicationContext配置数据源等信息即可
