• Components such as services,directives,filters,and animations are defined by an injectable factory method or constructor function. These components can be injected with "service" and "value" components as dependencies.
  组件像 services,filters和 animations 都是通过可被注入的工厂函数或构造函数定义的。

• Controllers are defined by a constructor function,which can be injected with any of the "service" and "value" components as dependencies,but they can also be provided with special dependencies. See Controllersbelow for a list of these special dependencies.
  controllers是通过构造函数定义的，可被注入'service'或'value'组件来作为依赖，但他们也可以作为特殊的依赖被提供。可通过点击蓝色链接来查看controllers作为特殊依赖的情况。

• The runmethod accepts a function,which can be injected with "service","value" and "constant" components as dependencies. Note that you cannot inject "providers" into runblocks.

• The config method accepts a function,which can be injected with "provider" and "constant" components as dependencies. Note that you cannot inject "service" or "value" components into configuration.
  config方法接收一个函数，用来被注入'provider'和'constant'组件作为依赖。注意，你不能注入'service'和'value'组件进入配置。

Factory Methods

angular.module('myModule', []).factory('serviceId', ['depService', function(depService) { // ...}]).directive('directiveName',136)">// ...}]).filter('filterName',136)">// ...}]);

Module Methods

 []).config(['depProvider', function(depProvider) { // ...}]).run([ Controllers 
 
 

   Controllers are "classes" or "constructor functions" that are responsible for providing the application behavior that supports the declarative markup in the template. The recommended way of declaring Controllers is using the array notation: 
 
 
 

   Controllers 是 "classes"或"constructor functions"，负责提供应用的行为用来支持模板中的指令标签。推荐定义控制器的方法是使用array注释： 
 
 
 
someModule.controller('MyController',68)">'$scope', 'dep1',68)">'dep2', function($scope, dep1, dep2) { ... $scope.aMethod = function() { ... } ...}]);
 
 
 

   Unlike services,there can be many instances of the same type of controller in an application. 
 
 
 

   不像services，在一个应用中可以有很多同类controller的实例 
 
 
 
 
 

   Moreover,additional dependencies are made available to Controllers: 
 
 
 

   而且，追加的依赖 也可被Controllers获取。 
 
 
 
 
 
$scope: Controllers are associated with an element in the DOM and so are provided with access to thescope. Other components (like services) only have access to the$rootScopeservice.
 
 

    $scope: 控制器是和DOM中的一个元素关联的，所以能够访问$scope。其他组件(像services)只能访问$rootScope服务。 
 
 
 
resolves: If a controller is instantiated as part of a route,then any values that are resolved as part of the route are made available for injection into the controller.
 
 

       resolves: 如果一个controller 被作为route的一部分实例化，那么任何作为路由一部分得到的值 是可注入进controller的。 
 
 Dependency Annotation
 
 
 

   Angular invokes certain functions (like service factories and controllers) via the injector. You need to annotate these functions so that the injector knows what services to inject into the function. There are three ways of annotating your code with service name information: 
 
 
 

   Angular 调用某些函数（像工厂类的service和controllers）通过 注入器。你需要给这些函数注释，这样注入器知道什么样的services要被注入到这个函数。这里有3个方法注释你的代码带上service的名字信息。 
 
 
 
 
 
Using the inline array annotation (preferred)
 
 

       使用行内数组注释（首选） 
 
 
 
Using the$injectproperty annotation
 
 

       使用$inject属性注释 
 
 
 
Implicitly from the function parameter names (has caveats)
 
 

       从函数参数中隐式注释 
 
 
 
 
 

  Inline Array Annotation（内联数组注释） 
 
 
 

   This is the preferred way to annotate application components. This is how the examples in the documentation are written. 
 
 
 

   这是首选的方法注释应用组件。下面是文档中的例子： 
 
 
 
 For example:
 
'greeter', greeter) { // ...}]);
 
 
 

   Here we pass an array whose elements consist of a list of strings (the names of the dependencies) followed by the function itself. 
 
 
 

   这里我们传入一个数组，数组元素由字符串列表（依赖的名字）然后跟上被调用的函数。 
 
 
 
 
 

   When using this type of annotation,take care to keep the annotation array in sync with the parameters in the function declaration. 
 
 
 

   当使用这种类型的注释时，要注意保持注释数组和函数参数同步。 
 
 
 
 $injectProperty Annotation（$inject属性注释）
 
 
 

   To allow the minifiers to rename the function parameters and still be able to inject the right services,the function needs to be annotated with the 
  $injectproperty. The 
  $injectproperty is an array of service names to inject. 
 
 
 

   为了允许the minifiers 重命名函数参数，但仍能够注入正确的services，函数需要被注释$inject属性。$inject属性是一个包含需要被注入的service名字的数组。 
 
 
 
var MyController = function($scope,136)">// ...}@H_497_502@MyController.$inject = ['greeter']; someModule.controller( @H_497_502@MyController);
 
 
 

   In this scenario the ordering of the values in the 
  $injectarray must match the ordering of the parameters in 
  @H_497_502@MyController. 
 
 
 

   在这个场景中，$inject数组中的值的顺序必须和被注释的函数参数的顺序匹配。 
 
 
 
 
 

   Just like with the array annotation,you'll need to take care to keep the 
  $injectin sync with the parameters in the function declaration. 
 
 
 

   就像‘数组注释’，你需要注意保持$inject和函数声明中参数的同步。 
 
 
 
 
 
 
 

  Implicit Annotation（隐式注释） 
 
 
 Careful:If you plan to 
 minifyyour code,your service names will get renamed and break your app. 
 
 
 

   注意：如果你计划精简你的代码，你的service名会被重命名，这样会破坏你的应用。 
 
 
 
 
  
 
 
 
 

   The simplest way to get hold of the dependencies is to assume that the function parameter names are the names of the dependencies. 
 
 
 

   获取依赖最简单的方法是假定函数参数名是这些依赖的名字。 
 
 
 
// ...});
 
 
 

   Given a function,the injector can infer the names of the services to inject by examining the function declaration and extracting the parameter names. In the above example,$scopeand 
  greeterare two services which need to be injected into the function. 
 
 
 

   给定一个函数，注入器会通过检查函数声明并摘取参数名来推断services的名字来注入这些services。在上面的例子中，$scope和greeter是两个需要被注入到函数的services。 
 
 
 
 
 

   One advantage of this approach is that there's no array of names to keep in sync with the function parameters. You can also freely reorder dependencies. 
 
 
 

   这种方法的一个优势是不需要去关心 ‘包含名字的数组’和函数参数的同步问题。你可以不用关心依赖的顺序。 
 
 
 
 
 

   However this method will not work with JavaScript minifiers/obfuscators because of how they rename parameters. 
 
 
 

   无论如何不能够生效当使用JavaScript压缩器/ 因为他们会重命名参数。
