从后端向前端传递数据到ajax

1.创建Java工程

js 插件引入

highcharts.js

jquery-1.8.3.min.js

myjs.js 引入ajax

2.前端代码

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>

3.后端代码：

public class DataConverterServlet extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

request.setCharacterEncoding("utf-8");

response.setContentType("text/html;charset=utf-8");

response.setCharacterEncoding("utf-8");

PrintWriter out = response.getWriter();

String jString ="["

+ "{name: '奥特曼',data: [800, 32, 40]},"

+ "{name: '怪兽boss',data: [1000, 27, 25]}"

+ "]";

out.print(jString);//将文本传递到前端ajax

}

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

this.doGet(request, response);

}

}
