girdle dependency

The DIP dependency reversal principle Dependency inversion Principle is defined as follows:high-level modules should not be dependent on low-class modules, they should all rely on abstraction .Suppose the controller relies on the instance/implementation of repository, not interface:In this example, the controller is a high-level module, and the repository is a low-class module.But by definition: high-level

InheritedRefers to a class or interface that inherits another class or interface and can add its own new functionality.RealizeRefers to a class that implements the interface interface.DependentSimply put, the method in one class uses another class, and the general dependency in Java is either a local variable, a formal parameter to a method, or a call to a static method. is a weak relationship. For example, when a person writes with a pen, the relatio

There are two ways of defining Controller,module,service,and directive,Way One:var mymodule = angular.module (' myApp ', []); Mymodule.controller (function($scope, Project) { }]);Way two:var mymodule = angular.module (' myApp ', []); function Myctrl ($scope, Project) { }mymodule.controller (' Myctrl ', Myctrl);There is no difference in nature between the two approaches, but the second one will cause the pollution of the scope.You may also realize that the methods of

The benefits of Dependency injection (DI) are no longer mentioned, as is known with the spring Framework. Angularjs as the foreground JS framework, also provides the support for Di, this is javascript/jquery not have the characteristic. In Angularjs, Angular.module (), Angular.injector (), $injector, $provide are associated with Di.

In C #-thanks to the automatic properties in c#3.0-we can easily create a property called "AuthorName" with the following code. public string AuthorName {get; set;} The code above is our familiar CLR attribute, and we can easily read/take the value of this property. In the Silverlight world, however, if you want to do something more, the CLR attribute is a bit out of the box. They include-animation, data binding, styles/templates, and so on. As a result, Microsoft has introduced the concept o

In Maven's dependency management, dependent scope settings are often used. Here is a list of various scope usage scenarios and instructions, as well as practical experience in use. Scope of use scenarios and descriptions 1.compile The compilation scope, default scope, is valid in the CLASSPATH (compilation environment) of the engineering environment and packaged (if the war package is included in the war package). 2.provided A container or JDK provi
