lightweight shipping container

About Docker:Docker is an open-source engine that makes it easy to create a lightweight, portable, self-sufficient container for any application. Developers who compile tests on notebooks can be deployed in batches in a production environment, including VMS (virtual machines), bare metal, OpenStack clusters, and other underlying application platforms.Docker is typically used for the following scenarios:

, and then into the Usermanager interface Usermanager Usermanager = ( Usermanager) Factory.getbean ("Usermanager") Usermanager.adduser ("Jiuqiyuliang", "123456");}} spirng configuration file: Applicationcontext.xml In the above configuration file can be free to switch the implementation of various databases, DAO layer of flexibility imaginable.Test structure of the project:People do not understand the place to see the comments in the code, I will provide you with two versions of the source:Spr

OverviewUnity is a lightweight and extensible dependency injection container that supports constructors, properties, and method invocation injections. Unity can handle the problems faced by developers who work on component-based software engineering. The key to building a successful application is to implement a very loosely coupled design. Loosely coupled applications are more flexible and easier to mainta

Dependency Injection, Di (Dependency injection), its role naturally needless to say, mentioned di containers, such as SPRING,PICOCONTAINER,EJB containers, and so on, recently, Google has created a more lightweight DI container ... Guice! No more nonsense, first see how guice is to achieve the injection. Define a simple service interface and its implementation: Package com.zuidaima.demo.guice; Public i
