Java：如何获取调用者函数名称 [英] Java: How to get the caller function name

问题描述

要修复测试用例，我需要确定是否从特定的调用函数调用该函数。我无法承受添加布尔参数，因为它会破坏定义的接口。如何解决这个问题？

To fix a test case I need to identify whether the function is called from a particular caller function. I can't afford to add a boolean parameter because it would break the interfaces defined. How to go about this?

这就是我想要实现的目标。这里我不能改变operation（）的参数，因为它是一个接口实现。

This is what I want to achieve. Here I can't change the parameters of operation() as it is an interface implementation.

operation()
{
   if not called from performancetest() method
       do expensive bookkeeping operation
   ...       

}

推荐答案

你可以尝试

StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
StackTraceElement e = stacktrace[2];//maybe this number needs to be corrected
String methodName = e.getMethodName();
