highcharts跟后台交互的demo

highcharts跟后台如何进行交互小demo，一个servlet，一个jsp页面，servlet用来往jsp页面输出数据，后台数据是随便写的，你可以根据需要改成自己需要的数据。
我这里的servlet往前台传的数据是字符串，然后在前台用js处理成json对象的，也可以往前台直接传json对象，我这里为了简单起见采用输出字符串。不多说了上代码：
servlet：
package com.highcharts.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet(name="lineServlet",urlPatterns="/lineServlet")

public class LineServlet extends HttpServlet {

private static final long serialVersionUID = 366512729238484827L;

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
// TODO Auto-generated method stub
this.doPost(req, resp);
}

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();

List data = new ArrayList();
for(int i = 1; i < 10; i++){
data.add(i);
}
List ll = new ArrayList();
for(int i=0; i <10; i++){
ll.add("\"data"+i+"\"");
}
String str = "";
str += "{\"title\":\"this is demo\",\"data\":"+data+",\"xAxis\":"+ll+"}";

out.println(str.toString());
   out.flush();
   out.close();
}

}
