Spring+struts 集成方案一：

1. web.xml

   <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath*:applicationContext-*.xml</param-value>

  </context-param>

  

    <listener>

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

    </listener>

 

2、在struts的Action中调用如下代码取得BeanFactory

     BeanFactory factory = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getSession().getServletContext());

 

3、通过BeanFactory取得业务对象，调用业务逻辑方法

 

     UserManager userManager = (UserManager)factory.getBean("userManager");   

spring+struts的集成(第二种集成方案)

 

原理：将业务逻辑对象通过spring注入到Action中，从而避免了在Action类中的直接代码查询

 

 

 

 

1. web.xml

<context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath*:applicationContext-*.xml</param-value>

  </context-param>

  

    <listener>

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

    </listener>

2、因为Action需要调用业务逻辑方法，所以需要在Action中提供setter方法，让spring将业务逻辑对象注入过来

public class LoginAction extends Action {

 

    private UserManager userManager;

   

    public ActionForward execute(ActionMapping mapping, ActionForm form,

           HttpServletRequest request, HttpServletResponse response)

           ……

    }

    public void setUserManager(UserManager userManager) {

       this.userManager = userManager;

    }

}

3、在struts-config.xml文件中配置Action

     * <action>标签中的type属性需要修改为org.springframework.web.struts.DelegatingActionProxy

      DelegatingActionProxy是一个Action，主要作用是取得BeanFactory，然后根据<action>中的path属性值到IoC容器中取得本次请求对应的Action

      <action path="/login"

       type="org.springframework.web.struts.DelegatingActionProxy"

              name="loginForm"

              scope="request"  

       >

           <forward name="success" path="/success.jsp"/>

       </action>

4、在spring配置文件中需要定义struts的Action,如：

     * 必须使用name属性，name属性值必须和struts-config.xml文件中<action>标签的path属性值一致

     * 必须注入业务逻辑对象

     * 建议将scope设置为prototype,这样就避免了struts Action的线程安全问题

<bean name="/login" class="com.bjsxt.usermgr.actions.LoginAction" scope="prototype">

       <property name="userManager" ref="userManager"/>

</bean>

 

 

SSH集成 web.xml

<context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath*:applicationContext-*.xml</param-value>

  </context-param>

  

   <listener>

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

   </listener>

  

  <filter>

    <filter-name>Spring character encoding filter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <init-param>

    <param-name>encoding</param-name>

    <param-value>GBK</param-value>

    </init-param>

  </filter>

 

  <filter-mapping>

    <filter-name>Spring character encoding filter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

 

  <filter>

    <filter-name>hibernateFilter</filter-name>

    <filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>

  </filter>

 <filter-mapping>

    <filter-name>hibernateFilter</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>
