如何得到调用这个方法的类的class name 和method name?

[waterborn]

class A {
public static void log() {
System.out.println(是谁调用了我?);
}
}

class B {
public static void main(String[] args) {
A.log();
}
}

输出结果:classname=A methodname=main

[crazycy]

写个堆栈类，把类名写入，到调用时，找其上层结点，大概原理

关注。

com.didoleo.demo.B调用了我
do something...

哪个方法调用的做不出。

[vcshcn]

是谁调用了我
System.out.println(getClass().getName());
