Constructor injection should be the main way that you do dependency injection. It’s simple: A class needs something and thus asks for it before it can even be constructed. By using the guard pattern, you can use the class with confidence, knowing that the field variable storing that depende...

依赖注入(dependency injection)最通俗的讲解 这篇文章解释了什么是依赖注入(又称控制反转),以及它如何改善定义业务逻辑的代码。 服务和依赖 服务可以是您编写的类,也可以是来自导入库的类。例如,它可以是一个 logger 或一个 database connection。因此,您可以编写一个无需任何外部帮助即可单独运行的服务,但也可能您...
I.e. passing the skills from outside the class. We could say that we injected an object in class Person. The example is really simple, but it perfectly illustrates how helpful could be this approach. In the example above we used injection to make our class looks better. We solved two ...
6.1. Setter Injection Setter-based DI is realized by calling setter methods on your beans after invoking a no-argument constructor or no-argument static factory method to instantiate your beans. In this example, we create a setter method for theApplicationContext, which Spring will use to inject...
