将Struts放入spring框架中

第一步：写好ACtion

package com.inspur.actions;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.actions.DispatchAction;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.inspur.forms.*;

public class LoginAction extends DispatchAction {
 //响应登录
  public ActionForward login(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response)
    throws Exception {
   System.out.println("******通过新的方式响应请求***********");
   /*
   
   EmployeeForm employeeForm=(EmployeeForm)form;
   //构建一个Employee对象
   Employee e=new Employee();
   e.setId(employeeForm.getId());
   e.setName(employeeForm.getName());
   e.setLeader(employeeForm.getLeader());
   e.setMid("111111");
   eif.addEmployee(e);
   request.getSession().setAttribute("adder", e);
   */
   return mapping.findForward("ok");
  }
  
}

第二步：配置structs:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//
DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
 <form-beans>
 <form-bean name="userForm" type="com.inspur.forms.UserForm" />
 </form-beans>
 <action-mappings>
 <action path="/login" parameter="flag" name="userForm" >
 <forward name="ok" path="/WEB-INF/welcome.jsp"/>
 <forward name="err" path="/WEB-INF/login.jsp"/> 
 </action>
 </action-mappings>
 <!-- 配置代理请求处理 DelegatingRequestProcessor ,它的用户是
 
  -->
 <!--这里配置代理，用spring 框架代理sruts-->
 <controller>
   <set-property property="processorClass" value="org.springframework.web.struts.DelegatingRequestProcessor"/>
 </controller>
</struts-config>

第三步：搭建spring框架：

（1）applicationContext.xml一般放在src目录下:

<?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: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/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

 

 

<!-- 配置action -->
<bean name="/login" scope="prototype" class="com.inspur.actions.LoginAction">
</bean>
</beans>

(2)让web.xml配置好，好让web容器初始化struts以及spring:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
  <display-name>VoteSystem</display-name>
 
 
  <!-- 开始配置struts -->
  <servlet>
 <servlet-name>struts</servlet-name>
 <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
 <init-param>
  <param-name>config</param-name>
  <param-value>/WEB-INF/struts-config.xml</param-value>
 </init-param>
 <load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
 <servlet-name>struts</servlet-name>
 <url-pattern>*.do</url-pattern>
</servlet-mapping>

<!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->
<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 对Spring容器进行实例化 -->
<listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

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