在返回上述接口的泛型接口中创建静态变量(或者至少在Spring中的映射器中)

public interface MyInterface<T> {
    static final int MY_STATIC_VARIABLE = 10;
    // ...
}

public interface MyInterface<T> {
    static final int MY_STATIC_VARIABLE = 10;

    void myMethod();

    default void myDefaultMethod() {
        System.out.println("My static variable: " + MY_STATIC_VARIABLE);
    }
}

@Component
public class MyMapper {

    public static final String MY_STATIC_VARIABLE = "Hello";

    // ...
}

MyInterface.myMethod();
System.out.println(MyInterface.MY_STATIC_VARIABLE);

MyMapper.MY_STATIC_VARIABLE;
