Spring+Struts2+Hibernate整合
整合过程
1、 配置srping启动监听器，使spring容器在web应用启动的时候启动，在web.xml中（
参考文档：H:\struts-2.2.1.1\docs\WW\spring-plugin.html）：
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
      
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:bean.xml</param-value>
</context-param>
2、 由Spring来管理Action
a、注解方式
@Component(value="testAction")
@Scope(value="prototype")
public class TestAction extends ActionSupport {
public String test(){
System.out.println("action........");
return this.SUCCESS;
}
}
b、也可以通过xml方式，把Action当作普通的bean
配置spring文件的头部引用：在spring-framework-2.5.6/docs/reference/html-single 输入XML查找然后复制
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
</beans>
（1）注入service到action中（注意：scope="prototype"表示不为单例模式，即每次执行增加或者修改操作都新创建一个action；property中的name值是class类中的变量）
 <bean id="userAction" class="com.action.UserAction" scope="prototype">
        <property name="userService">
            <ref bean="userService" />
        </property>
</bean>
      
（2）读src下的属性文件的bean配置
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="locations">
      <value>classpath:myserver.properties</value>
    </property>
  </bean>
3、 由Spring来管理Hibernate
（1）配置数据源，连接数据库：value中的值在myserver.properties文件中定义，注意变量名要一致
<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName"><value>${jdbc.driverClass}</value></property>
    <property name="url"><value>${jdbc.url}</value></property>
    <property name="username"><value>${jdbc.user}</value></property>
    <property name="password"><value>${jdbc.password}</value></property>
  </bean>
（2）配置SessionFactory
<bean id="mySessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource"/>
    <property name="mappingResources">
      <list>
        <value>User.hbm.xml</value>
      </list>
    </property>
    <property name="hibernateProperties">
      <props>
        <prop key="hibernate.dialect">${hibernate.dialect}</prop>
        <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
      </props>
    </property>
  </bean>
（3）配置事务管理
模板化hibernate持久层
<bean id="myTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
       <property name="sessionFactory" ref="mySessionFactory"/>
</bean>
<bean id="myTxManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
         <property name="sessionFactory">
            <ref bean="mySessionFactory" />
        </property>
    </bean>
<tx:advice id="txAdvice" transaction-manager="myTxManager">
    <tx:attributes>
      <tx:method name="*" propagation="REQUIRED"/>
    </tx:attributes>
  </tx:advice>
       
  <aop:config>
    <aop:pointcut id="myServiceMethods" expression="execution(* com.service.*.*(..))"/>
    <aop:advisor advice-ref="txAdvice" pointcut-ref="myServiceMethods"/>
  </aop:config>
定义Dao父类模板,要为抽象的，把模板化的hibernate持久层注入到dao中
<bean id="baseDao" abstract="true">
<property name="hibernateTemplate">
            <ref bean="myTemplate" />
        </property>
</bean>
把dao注入到service层
 <bean id="userDao" class="com.dao.impl.UserDaoImpl" parent="baseDao" ></bean>
         
     <bean id="userService" parent="myProxy" >
        <property name="target"> 
            <bean class="com.service.impl.UserServiceImpl" >
  <property name="userDao">
      <ref bean="userDao" />
  </property>
    </bean>
        </property>
    </bean>
<!-- 配置事务代理机制 -->
    <bean id="myProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">
     <property name="transactionManager" ref="myTxManager"/>
     <property name="transactionAttributes">
      <props>
        <prop key="*">PROPAGATION_REQUIRED</prop>
      </props>
    </property>
  </bean>
      
（4）Properties中sqlserver与mysql的连接方式
#jdbc.driverClass="com.microsoft.jdbc.sqlserver.SQLServerDriver"
jdbc.driverClass=com.mysql.jdbc.Driver
#jdbc.url="jdbc:sqlserver://127.0.0.1:3306;DatabaseName=test"
jdbc.url=jdbc:mysql://localhost:3306/test
jdbc.user=root
jdbc.password=root
      
#hibernate.dialect="org.hibernate.dialect.SQLServerDialect"
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.show_sql=true
      
4、 Hibernate的*.hbm.xml的配置
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
      
<hibernate-mapping>
<class name="com.model.User" table="SHOPUSER">
        <id name="id" column="USER_ID">
            <generator class="native"/>
        </id>
        <property name="userName" type="java.lang.String" column="USER_NAME"/>
    </class>
</hibernate-mapping>
      
5、 Struts2的配置
(1）写struts2.xml文件：
复制：struts-2.2.1.1\apps\struts2-blank\web-inf\classes\struts.xml,粘贴在项目src下，内容如下
<?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>
      
    <constant name="struts.enable.DynamicMethodInvocation" value="true" />
    <constant name="struts.devMode" value="true" />
      
    <package name="default" namespace="/" extends="struts-default">
        <action name="userAction" class="com.action.UserAction" method="query">
            <result name="list">/user_list.jsp</result>
        </action>
    </package>
      
</struts>
（2）导入包：struts-2.2.1.1\apps\struts2-blank\web-inf\lib下的所有包,粘贴在lib下
（3）配置web.xml文件：
找到struts-2.2.1.1\apps\struts2-blank\web-inf\web.xml,复制其中的<filter>……</filter-mapping>,粘贴在项目中的web.xml中，如：
<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>
