1、代码如下：
//app.js
import angular from "angular";
import uiRouter from "angular-ui-router";
import routing from "./app.config";
import HomeController from "./controllers/home.controller";
let app = angular.module('app', [uiRouter]);
app.config(routing)
.controller('HomeController', HomeController)2、home.controller.js代码如下：
class HomeController{
constructor($scope){
console.info('为什么这里运行了两次？');
}
}
HomeController.$inject = ['$scope'];
export default HomeController;3、app.config.js代码如下：
routing.$inject = ['$stateProvider', '$urlRouterProvider', '$locationProvider'];
export default function routing($stateProvider, $urlRouterProvider, $locationProvider){
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('home', {
url: '/home',
templateUrl: require('../views/home.html'),
controller: 'HomeController',
title: '社区综合受理平台'
})
.state('record', {
url: '/record',
templateUrl: 'views/record.html',
controller: 'RecordController',
title: '社区服务综合受理记录'
})
.state('guide', {
url: '/guide',
templateUrl: 'views/guide.html',
title: '社区受理服务事项'
})
.state('proof', {
url: '/proof',
templateUrl: 'views/proof.html',
controller: 'ProofController',
title: '居住证明'
})
.state('poor', {
url: '/poor',
templateUrl: 'views/poor.html',
controller: 'PoorController',
title: '就业困难人员待定'
})
};4、html如下：
<!DOCTYPE html>
<html xmlns:ng="http://angularjs.org" id="ng-app" lang="en" ng-app="app">
<head>
<meta charset="UTF-8">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"/>
<title ng-bind="title"></title>
</head>
<body ng-controller="MainController" ui-view>
</body>
</html>5、home.html:
<p id="root">
<p class="head clearfix">
<ul class="title clearfix">
<li>
<h3 ng-bind="title"></h3>
</li>
</ul>
</p>
<p class="content">
<p class="content-wrap clearfix index-content" ng-controller="HomeController">
这个是模板！！！
</p>
</p>
</p>6、问题：为什么constrcutor()运行了2次？

라우팅 구성 및 html 조각 페이지를 볼 수 있나요?
일반적으로 컨트롤러는 라우팅에 구성되고 ng-controller는 라우팅 html 조각에 선언됩니다.
------선 구분------
당연하지 않나요! 경로에 HomeController를 구성하고 home.html에 ng-controller="HomeController"를 선언했습니다. 물론 두 번 실행됩니다!
