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。
