}

This is a "field injection". You can usually choose one of three types:

Each has its own advantages and disadvantages. During testing, field injection is common practice.

In the case of @Autowiring in a class, for example:

public class Test {

    @Autowired
    TestService service;
    ...
}

Free your object from using reflection hence no need for Setter methods
