Java记录器，自动确定调用者的类名 [英] Java logger that automatically determines caller's class name

问题描述

public static Logger getLogger() {
    final Throwable t = new Throwable();
    final StackTraceElement methodCaller = t.getStackTrace()[1];
    final Logger logger = Logger.getLogger(methodCaller.getClassName());
    logger.setLevel(ResourceManager.LOGLEVEL);
    return logger;
}

此方法将返回一个记录器，该记录器知道它正在记录的类。
反对它的任何想法？

This method would return a logger that knows the class it's logging for. Any ideas against it?

推荐答案

我想这会为每个课程增加很多开销。每个班级都必须抬头。你创建了新的Throwable对象......这些throwable不是免费的。

I guess it adds a lot of overhead for every class. Every class has to be 'looked up'. You create new Throwable objects to do that... These throwables don't come for free.
