The content of this article basically comes from "angularjs authoritative course"An object typically has three ways to gain control over its dependencies: Create a dependency internally Referencing by global variables Pass through parameters where needed Dependency injection is implemented in the third way. Dependency Injection is a design pattern that removes hard-coded dependencies, which can change or even remove dependencies at run time.The ability to modify dependencie

Using object Simulation Injection We can very easily use the Angularjs $provider service with an object to simulate a dependency and inject. Examples are as follows Angular.module (' artists ', []). Factory (' Artists ', [' Imagestore ', function (Imagestore) {return { thumb:function ()] {return Imagestore.thumbnailurl (ID)}} ]) How to Achieve How to determine the service 1. Create a reference to a URL that will be captured later by a mock, and a variable

Objection is a lightweight, dependency injection framework"Dependency Injection" is a design pattern for object-oriented programming to reduce the coupling between code. is usually implemented based on an interface, which means that no new object is required, but the object is obtained through the associated controller. the Laravel of the 2013 's hottest PHP framework is typical. The specific use is as follows:1. First createProtocol file@protocol Pphomeviewcontrollerprotocol @end2. Initializat

);} The injector simply returns the value as is. But what if you want to compute the value? Then use a factory Provide.factory (' B ', function (a) {return a*2;}); function Controller (b) {expect (b). toequal (246);} So is factory a function which are responsible for creating the value. Notice The factory function can ask for other dependencies. But what if want to is more OO and has a class called Greeter? function Greeter (a) {This.greet = function

Injection1. Inferred typeThis injection method does not need to focus on the sequencing of the parameters, and Ng infers whether the service exists. You cannot handle compressed or obfuscated code, only the original code.2. Marker typeCall the $inject property directly to complete the dependency injectionvar ctrfunc=function ($scope, $show, $write) { $scope. funcBtn1=function () { $show. Show (); } $scope. funcBtn2=function() { $write. write

Requirements: Recently done a background run JAR package application, not using a Web container, using Java-jar xxxxx way to run. Database connection pool with C3P0, shutdown after application The discovery database session still exists. Solution: Use the Runtime.getruntime (). Addshutdownhook (Thread Hook) to close the database connection before the application is closed, which is suitable for using System.exit (int) exits the application mode. Because the jar package uses the Main method start

that the filter is also a service, so you can inject it into your code.Unlike the normal service, when the filter is registered in the injector, the name is appended with a suffix: filter. For example, the service name of the number filter is: Numberfilter, and the service name of the currency filter is: Currencyfilter.Usually our code is encapsulated in three places: controllers, services, instructions. These places support direct injection of servi

the modules that are relevant to the current test. The above is just a suggestion, you can rest assured according to your specific situation to adjust.A module is a collection of configurations and blocks of code that are attached to the application at the start-up phase. One of the simplest modules consists of a collection of two blocks of code:Configuration code block-executes during the injection provider injection and configuration phase. Only injected providers and constants can be injecte
