为angular-ui-router（https://github.com/angular-ui/ui-router）的示例代码（ui-router / sample / index.html）看起来像这样的任何解释。具体做法是：
为什么依赖的规范如下：
angular.module（'sample'，['ui.compat']） 的.config（ ['$ stateProvider'，'$ routeProvider'，'$ urlRouterProvider'， function（$ stateProvider，$ routeProvider，$ urlRouterProvider）{

ui-router并不完全支持这一点。您可以检查此库以获取嵌套路由：http://angular-route-segment.com
它提供了创建树状路由层次结构的功能，可以在不丢失状态的情况下进行更改。
$routeSegmentProvider.
when('/section1', 's1.home').
when('/section1/prefs', 's1.prefs').
when('/section1/:id', 's1.itemInfo.overview').
when('/section1/:id/edit', 's1.itemInfo.edit').
when('/section2', 's2').
segment('s1', {
templateUrl: 'templates/section1.html',
controller: MainCtrl}).
within().
segment('home', {
templateUrl: 'templates/section1/home.html'}).
segment('itemInfo', {
templateUrl: 'templates/section1/item.html',
controller: Section1ItemCtrl,
dependencies: ['id']}).
within().
segment('overview', {
templateUrl: 'templates/section1/item/overview.html'}).
segment('edit', {
templateUrl: 'templates/section1/item/edit.html'}).
up().
segment('prefs', {
templateUrl: 'templates/section1/prefs.html'}).
up().
segment('s2', {
templateUrl: 'templates/section2.html',
controller: MainCtrl});

嵌套只是做这个例子的一种方式。你可以写
'navTitle@': {
templateUrl : 'pages/mypage.html',
controller: 'myController',
},
然后只需在应用中的任何其他位置定义myController。
function myController ($scope) {
};
就依赖性问题而言...这是以角度注入依赖项的一种方式，因此您可以在其他地方重用代码。
.factory('appLoading', function($rootScope, $state) {
return {
loading : function() {
$rootScope.status = 'loading';
if(!$rootScope.$$phase) $rootScope.$apply();
},
ready : function(delay) {
function ready() {
$rootScope.status = 'ready';
$rootScope.title = $state.current.data.title;
if(!$rootScope.$$phase) $rootScope.$apply();
}
}
};
})
然后，如果我想在一个模块中调用这个加载器，它将进入[]
喜欢在ui-router内的状态的onExit ...
onExit: ['appLoading',
function ( appLoading) {
appLoading.loading();
}],
