环境:eclipse+struts

要实现的效果:点击按钮提交数据到后台之后回到前台显示出来数据

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" 
  pageEncoding="UTF-8"%> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 
<title>Insert title here</title> 
</head> 
<body> 
<input type="text" id="userinput"> 
<input type="button" id="submit"> 
<div id="msg"></div> 
</body> 
<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-2.1.0.js">

 struts.xml

<action name="TestAction" class="com.action.Test"> 
  <result>index.jsp</result> 
</action> 

Test.java

package com.action; 
 
import java.io.PrintWriter; 
import java.util.Map; 
 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
 
import org.apache.struts2.ServletActionContext; 
 
import com.opensymphony.xwork2.ActionContext; 
import com.opensymphony.xwork2.ActionSupport; 
 
public class Test extends ActionSupport { 
  @Override 
  public String execute() throws Exception { 
    // TODO Auto-generated method stub 
    HttpServletRequest request = org.apache.struts2.ServletActionContext.getRequest(); 
    HttpServletResponse response = ServletActionContext.getResponse(); 
    request.setCharacterEncoding("utf-8"); 
    response.setCharacterEncoding("utf-8"); 
    PrintWriter out = response.getWriter(); 
    out.write(request.getParameter("username")); 
    out.flush(); 
    out.close(); 
    return SUCCESS; 
  } 
} 

以上这篇ajax提交到java后台之后处理数据的实现就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。
