AngularJS不提供任何直接实现服务继承的机制，但是对于您而言，您可以使用$
provide.decorator扩展
baseService自身或像
ChildService使用普通Javascript
的原型一样使用它。在我的实践中，为了使服务具有可配置的状态和行为，我使用provider。在以下所有示例中，控制台输出将为
World 。
装饰器
如果您
baseService的模块中不需要原件，则可以装饰它
柱塞
function alertService() { this.add = function(level, message) { switch(level) { case 'success': console.log(message); } }}function baseService(alertService) { this.message = "Hello"; this.perform = function () { alertService.add("success",this.message); };}angular. module('app',[]). config(['$provide', function($provide) { $provide.decorator('baseService', function($delegate) { $delegate.message = 'World'; return $delegate; }); }]). service('alertService', alertService). service('baseService', ['alertService',baseService]). controller('ctrl', ['baseService', function(baseService) { baseService.perform(); }]);原型继承
