在父类中记录静态方法 [英] logging static methods in a parent class

问题描述

我有一个抽象类Parent，有2个子类A和B.Parent有一个称为do()的静态方法.我想知道是否有一种静态方法可以在Logger中为类A添加日志信息(称为A.do())，并在日志B中添加日志信息(称为B.do()).通常

I have an abstract class Parent, with 2 subclasses A and B. Parent has one static method called do(). I am wondering if there is a way for that static method to add log info in Logger for class A when it's called as A.do() and log B when it's called as B.do(). The usual

protected final Logger LOGGER = Logger.getLogger(getClass());

不会像do()是静态方法那样工作，因此Logger也需要是静态的，但是getClass()方法显然不是静态的.

won't work as do() is a static method so Logger needs to be static as well, but the getClass() method is obviously not static.

谢谢.

推荐答案

我不推荐使用，但是如果您真的想要...

I wouldn't recommend it, but if you really want it...

public class A {
  public static void do() {
    doImpl(A.class);
  }
  protected static void doImpl(Class<?> refClass) {
  }
}

public class B extends A {
  public static void do() {
    doImpl(B.class);
  }
}
