登录时显示登录名

1.编写后台代码LoginController.java

package com.xxx.user.controller;import java.util.HashMap;import java.util.Map;import org.springframework.security.core.context.SecurityContextHolder;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestController    @RequestMapping("/login")    public class LoginController {        @RequestMapping("/name")        public Map name(){            String name = SecurityContextHolder.getContext().getAuthentication().getName();            Map map = new HashMap();            map.put("loginName", name);            return map;        }    }

2.编写前端代码,引入loginService.js

app.service('loginService',function($http){    this.loginName=function(){        return $http.get("../login/name.do");    }})

3.引入indexController.js

app.controller('indexController',function($scope,loginService){    $scope.showLoginName = function(){        loginService.loginName().success(function(response){            $scope.loginName = response.loginName;        })    }})

4.引入base.js

var app=angular.module('xxx',[]);

5.在主页面里引入js

<script type="text/javascript" src="./plugins/angularjs/angular.min.js"></script><script type="text/javascript" src="./js/base.js"></script><script type="text/javascript" src="./js/service/loginService.js"></script><script type="text/javascript" src="./js/controller/indexController.js"></script>

6.在body里添加模板ng-app,控制器ng-controller,初始化ng-init

<body ng-app="xxx" ng-controller="indexController" ng-init="showLoginName()">

7.使用angularjs表达式引入用户名

<span class="name">{{loginName}}</span>
