Struts1.2 + Spring2.0 + Hibernate3.1

web.xml 配置：

1. <!-- Struts 1 Configuration --> 
2. <servlet> 
3.         <servlet-name>action</servlet-name> 
4.         <servlet-class> 
5.             org.apache.struts.action.ActionServlet  
6.         </servlet-class> 
7.         <init-param> 
8.             <param-name>config</param-name> 
9.             <param-value>/WEB-INF/struts-config.xml</param-value> 
10.         </init-param> 
11.         <init-param> 
12.             <param-name>debug</param-name> 
13.             <param-value>2</param-value> 
14.         </init-param> 
15.         <init-param> 
16.             <param-name>detail</param-name>

22.     <servlet-mapping> 
23.         <servlet-name>action</servlet-name> 
24.         <url-pattern>*.do</url-pattern> 
25.     </servlet-mapping> 
26. <!-- Spring 2 Configuration --> 
27. <context-param> 
28.         <param-name>contextConfigLocation</param-name> 
29.         <param-value>/WEB-INF/applicationContext.xml</param-value>

31.  
32.     <listener> 
33.         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
34.     </listener> 
35.  
36.     <filter> 
37.         <filter-name>CharacterEncoding</filter-name> 
38.         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

45.         <filter-name>CharacterEncoding</filter-name> 
46.         <url-pattern>/*</url-pattern> 
47.     </filter-mapping> 

struts-config.xml

    这里的Action使用DelegatingActionProxy进行托管，所有Action应该托管此类

1. <!-- Bean Configuration --> 
2. <form-beans> 
3.         <form-bean name="user" type="com.ssh1.beans.User"></form-bean> 
4.     </form-beans> 
5.  
6. <!-- Action Configuration --> 
7.     <action-mappings> 
8.         <action name="user" path="/login" input="/input.jsp" scope="request" 
9.             type="org.springframework.web.struts.DelegatingActionProxy"> 
10.             <forward name="success" path="/success.jsp"></forward> 
11.             <forward name="failure" path="/failure.jsp"></forward> 
12.         </action> 
13.     </action-mappings> 

applicationContext.xml

   这里需要注意的是，applicationContext中的Action配置的name要与struts-config.xml中Action的path值相同

1. <!-- Service Configuration -->
2. <bean id="userService" class="com.ssh1.service.UserService" factory-method="getInstance" lazy-init="true"/> 
3.     
4. <!-- Action Configuration -->
5. <bean name="/login" class="com.ssh1.actions.LoginAction" lazy-init="true" depends-on="userService"> 
6.         <property name="service"><ref local="userService"/></property> 
7.     </bean>
