spring与struts2的整合

工程文件结构图：

1，创建名为loginSpringStruts2的web工程，具体机构如上图，在该工程的/WebRoot/WEB-INF/lib路径下添加struts2常用的JAR包（参见“struts2配置”），同时添加名为spring.jar,  commons-loggin.jar(已经添加），cglib-nodep-2.1_3.jar(AOP用到），struts2-spring-plugin-2.0.11.jar等4个Spring运行库文件。

2，创建前台视图login.jsp  success.jsp  error.jsp,　　具体参见（“struts2配置”

3，在src下创建applicationContext.xml,配置如下：

View Code

<?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:p="http://www.springframework.org/schema/p"

    xsi:schemaLocation="http://www.springframework.org/schema/beans 

    http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

    

    <!-- 配置Struts2里的Action对象 -->

    <bean id="login" class="action.LoginAction"></bean>

</beans>

4，在src下创建struts.properties消息文件，添加“struts.objectFactory=spring"语句，使得Struts2类的生成交给spring完成，具体代码：

View Code

struts.objectFactory=spring

struts.action.extension=action

struts.locale=en_GB

5，在src下创建struts.xml, 具体配置如下：

View Code

<?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>

    



<package name="main" extends="struts-default">

    <action name="login" class="action.LoginAction">

        <result name="error">/error.jsp</result>

        <result name="success">/success.jsp</result>

    </action>

</package>



</struts>

　　相应的action.LoginAction代码如下：

View Code

package action;



import com.opensymphony.xwork2.ActionSupport;



public class LoginAction extends ActionSupport {

    private String userName;

    private String userPsw;

    



    public String getUserName() {

        return userName;

    }





    public void setUserName(String userName) {

        this.userName = userName;

    }





    public String getUserPsw() {

        return userPsw;

    }





    public void setUserPsw(String userPsw) {

        this.userPsw = userPsw;

    }





    /**

     * @return

     */

    public String execute() {

        if(getUserName().equals("123")&& getUserPsw().equals("123")){

            return SUCCESS;

        }



        

        else return ERROR;

    }

}

　　相应的filter.CharacterEncodingFilter.java的代码如下：

View Code

package filter;



import java.io.IOException;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;



public class CharacterEncodingFilter implements Filter {

    private String characterEncoding;//编码方式在web.xml中

    private boolean enabled;//是否启动filter，初始值在web.xml中

    

    @Override

    public void init(FilterConfig config) throws ServletException {

        // TODO Auto-generated method stub

        //初始化时加载参数

        //从配置文件中读取设置到编码方式

        characterEncoding=config.getInitParameter("characterEncoding");

        //启动该过滤器完成编码方式到修改

        enabled="true".equalsIgnoreCase(characterEncoding.trim())

            ||"1".equalsIgnoreCase(characterEncoding.trim());

        

    }

    

    @Override

    public void doFilter(ServletRequest request, ServletResponse response,

            FilterChain chain) throws IOException, ServletException {

        // TODO Auto-generated method stub

        if(enabled||characterEncoding!=null){

            request.setCharacterEncoding(characterEncoding);//设置request编码方式

            response.setCharacterEncoding(characterEncoding);//设置response编码方式

        }

        chain.doFilter(request, response);//doFilter将修改好的request和response参数向下传递；

        

    }



    @Override

    public void destroy() {

        // TODO Auto-generated method stub

        characterEncoding=null;

        

    }



    







}

6，配置web.xml，包括struts2监听，字符集过滤，spring的web监听，并通过<context-param>标签来配置applicationContext.xml文件的位置

View Code

<?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>

  

  <!-- struts2过滤器 -->

    <filter>

      <filter-name>struts</filter-name>

      <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>

      <init-param>

          <param-name>struts.action.extension</param-name>

          <param-value>action</param-value>

      </init-param>

  </filter>

  <filter-mapping>

      <filter-name>struts</filter-name>

      <url-pattern>/*</url-pattern>

  </filter-mapping>

  

  <!-- 字符集过滤器 -->

  <filter>

      <filter-name>characterEncodingFilter</filter-name>

      <filter-class>filter.CharacterEncodingFilter</filter-class>

      <init-param>

          <param-name>characterEncoding</param-name>

          <param-value>UTF-8</param-value>

      </init-param>

      <init-param>

          <param-name>enable</param-name>

          <param-value>true</param-value>

      </init-param>

  </filter>

  <filter-mapping>

      <filter-name>characterEncodingFilter</filter-name>

      <url-pattern>/*</url-pattern>

  </filter-mapping>

  

  <!-- spring的监听 -->

  <listener>

      <listener-class>

          org.springframework.web.context.ContextLoaderListener

      </listener-class>

  </listener>

  <context-param>

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

      <param-value>/WEB-INF/classes/applicationContext.xml</param-value> 

  </context-param>

  

  

</web-app>
