    (1) 后台AngularController.java代码

    package com.amy.controller;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import net.sf.json.JSONArray;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class AngularController {
    
        /**
         * 获取所有客户信息
         * 
         * @return
         */
        @RequestMapping(value = "/angular/postCustomersList", method = RequestMethod.POST, produces = "text/html;charset=UTF-8")
        @ResponseBody
        public String postCustomersList(String userName) {
            System.out.println(userName);
            List<String> customers = new ArrayList<>();
            customers.add("post");
            customers.add("张三");
            customers.add("李四");
            customers.add("老王");
            customers.add("老张");
            customers.add("amy");
            JSONArray array = JSONArray.fromObject(customers);
            System.out.println(array.toString());
            return array.toString();
        }
        
        @RequestMapping(value = "/angular/getCustomersList", method = RequestMethod.GET, produces = "text/html;charset=UTF-8")
        @ResponseBody
        public String getCustomersList(String userName) {
            System.out.println(userName);
            List<String> customers = new ArrayList<>();
            customers.add("get");
            customers.add("张三");
            customers.add("李四");
            customers.add("老王");
            customers.add("老张");
            customers.add("amy");
            JSONArray array = JSONArray.fromObject(customers);
            System.out.println(array.toString());
            return array.toString();
        }
    
        @RequestMapping(value = "/angular/customersList", method = RequestMethod.GET)
        public String CustomersList() {
            return "angular/customerList";
        }
    }

    (2)customerList.jsp页面

    <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"%>
    <%@ 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">

    </body>
    </html>

    (3)customerList.js代码

    /**
     * 客户信息列表
     */
    
    var app = angular.module("myApp", []);
    
    // post方法
    app.controller("postCustomersController", function($scope, $http){
    
        // 原谅我吧,我不知道这一句是用来干什么的。换成将text换成‘’,似乎也没有什么影响
        // 但是必须有
        var postData  = {
            text:'long blob of text'
        };
    
        var myData = {
            userName : "张三"
        };
        $http.post("angular/postCustomersList",postData, {params:myData}).success(function(data, status, headers, config) {
            $scope.names = data;
        }).error(function(data, status, headers, config) {
            console.log(data);
            console.log(status);
            console.log(headers);
            console.log(config);
        });
    });
    
    // get方法获取数据
    app.controller("getCustomersController", function($scope, $http){
        $http.get("angular/getCustomersList", {params:
            {userName : "张三"}
        }).success(function(data, status, headers, config) {
            $scope.names = data;
        }).error(function(data, status, headers, config) {
            console.log(data);
            console.log(status);
            console.log(headers);
            console.log(config);
        });
    });

    (4)测试

      输入地址:http://localhost:8080/SpringMVC01/angular/customersList

      页面展示为:

      

      说明:只有post方法进入后台了,推测controller一个页面只有一个。

    后台打印的代码如下:

    张三
    ["post","张三","李四","老王","老张","amy"]
    张三
    ["post","张三","李四","老王","老张","amy"]
    张三
    ["post","张三","李四","老王","老张","amy"]
    张三
    ["post","张三","李四","老王","老张","amy"]
    张三
    ["post","张三","李四","老王","老张","amy"]
