What are the ways to implement dependency injection? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The implementation methods of dependency injection are: 1, interface injection, define the information to be injected in the interface, and complete the injection through the interface; 2, set injection, define a set method in the class that accepts injection, and define the elements that need to be injected in the parameters; 3, construct injection, define a construction method in the class that accepts injection, and define the elements that need to be injected in the parameters.

There are three ways of dependency injection:

1: interface injection: refers to defining the information to be injected in the interface and completing the injection through the interface.

2:set injection: this means defining a set method in the class that accepts the injection and defining the elements to be injected in the parameters.

3: construction injection: refers to defining a constructor in the class that accepts the injection and defining the elements that need to be injected in the parameters.

The most commonly used method is setter () method injection. Let's take the property setter () method injection as an example to explain how the Spring container implements dependency injection in the application.

This is the answer to the question about the implementation of dependency injection. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
