[JAVA] I want to target static fields to @Autowired

Especially when designing utility classes, there are times when you want to target static fields to @ Autowired. In this case, it seems that you should define the setter of the target static field as a non-static method and add @Autowired to that setter. The following is an example.

public class SampleClass {

    private static StaticField staticField;

    public void setStaticField(StaticField staticField) {
        SampleClass.staticField = staticField;


However, since it is bad know-how, if you have to repeat the above frequently, it seems that you will need to review the design, such as making the class a singleton. The reality of system development is that the design cannot be reviewed so easily (´ ・ ω ・ `).
