How to check which class invoked a method

Question

I need to get the name of the class in an over-ridden method which has called the method

How can it be done?

Answer 1

Throwable t = new Throwable(); 
StackTraceElement[] elements = t.getStackTrace(); 

Class StackTraceElement has various methods like

String calleeMethod = elements[0].getMethodName(); 
String callerMethodName = elements[1].getMethodName(); 
String callerClassName = elements[1].getClassName(); 

Answer 2

您可以使用this.getClass()方法内部的当前对象的类，或使用Thread.currentThread().getStackTrace()遍历调用路径。

Answer 3

You can get the class with:

class.getMethod("your_over-ridden_method_name").getDeclaringClass();

For example:

System.out.println(class.getMethod("your_over-ridden_method_name") + " declared by " + class.getMethod("your_over-ridden_method_name").getDeclaringClass());
