前台代码：

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

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html ng-app="notesApp">
<head>
<base href="<%=basePath%>">

<script src="angular1.4.6.min.js"></script>
</head>

<body>
<table ng-controller="MainCtrl as ctrl" border="1px">
<tr ng-repeat="member in ctrl.items">
<td><span ng-bind='member.id'/></td>
<td><span ng-bind='member.name'/></td>

</tr>
</table>
</body>
</html>

<script type="text/javascript">
<!--
angular.module('notesApp',[])
.controller('MainCtrl',['$http',function($http){

var self=this;
self.items=[];

var url="/angularjsAjax/Members";
$http.get(url).then(function(response){
self.items=response.data;
},function(errResponse){
alert('error'+errResponse);
});
}]);
//-->
</script>

后台代码：

package com.test;

import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;

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

import net.sf.json.JSONArray;

public class MembersServlet extends HttpServlet {
private static final long serialVersionUID = 56890894234786L;

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
request.setCharacterEncoding("UTF-8");
PrintWriter out = response.getWriter();

List<Member> ls=new ArrayList<Member>();
ls.add(new Member("001","Andy",20));
ls.add(new Member("201","Bill",40));
ls.add(new Member("501","Cindy",60));
ls.add(new Member("901","Eintein",88));

JSONArray jArray=JSONArray.fromObject(ls);
String json=jArray.toString();

System.out.println("json="+json);
out.print(json);
out.flush();

return;
}

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, java.io.IOException {
doPost(request, response);
}
}

Member类代码：

package com.test;

public class Member{
public Member(String id,String name,int age){
this.id=id;
this.name=name;
this.age=age;
}

private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
private int age;
}
