感谢这两位朋友游目骋怀和一梦春秋的原创分享

想通过在jsp页面上点击某个按钮用Ajax实现与服务器端的交互,然后是通过配置struts.xml跳转到服务器端某个Action进行处理,最常用的就是注册,登录的用户名验证了.主要的思路:

1、客户端是通过$.ajax()方法向struts2.action传递数据；

2、其中action中execute()方法返回值为空，并通过【ServletActionContext.getResponse().getWriter().print(result);】方法将数据传到jQuery中。

TestAjax.jsp代码:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

    <base href="<%=basePath%>">

    .divFrame .divTitle{padding:5px;background-color:#eee}

    .divFrame .divContent{padding:8px}

    .divFrame .divContent .clsShow{font-size:14px}

    .btn{border:#666 1px solid;padding:2px;width:50px;

    form{padding:0px;margin:0px}

    }

             // alert(mName);
              $.ajax(

                  success:function(strValue)
                  {
                     alert(strValue);
                     if(strValue=="true"){
                         $("#divTip").html("操作提示，登录成功！");
                     }else

struts.xml配置信息:

LoginCheckAction.java代码:

package test;
import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

public class LoginCheckAction extends ActionSupport {
        /**
   *
   */
   private static final long serialVersionUID = 1L;
       private String mname;
        private String mpass;
        /*getter和setter方法*/
        public void setMname(String mname){
           this.mname=mname;
        }
        public String getMname(){
           return this.mname;
        }
        public String getMpass(){
           return this.mpass;
        }
        public void setMpass(String mpass){
           this.mpass=mpass;
        }

        public String execute() throws Exception {
               boolean result=false;
               if("abc".equals(mname)&& "123".equals(mpass))
               {
                       result=true;
               }
           //向客户端传递数据
              ServletActionContext.getResponse().getWriter().print(result);
            return null;
        }
   }
