如何在java中获取方法的字符串名称？ [英] How to get string name of a method in java?

问题描述

如何通过反射找出该方法的字符串名称是什么？

How can I find out through reflection what is the string name of the method?

例如给定：

class Car{
   public void getFoo(){
   }
}

我想得到字符串getFoo，如下所示：

I want to get the string "getFoo", something like the following:

 Car.getFoo.toString() == "getFoo" // TRUE

推荐答案

由于方法本身不是对象，因此它们没有直接属性（就像您期望的JavaScript语言中的第一类函数一样）。

Since methods aren't objects themselves, they don't have direct properties (like you would expect with first-class functions in languages like JavaScript).

你最接近的是致电 Car.class.getMethods（）

The closest you can do is call Car.class.getMethods()

Car.class 是 Class 对象，您可以使用它来调用任何反射m方法。

Car.class is a Class object which you can use to invoke any of the reflection methods.

但据我所知，一种方法无法识别自身。

However, as far as I know, a method is not able to identify itself.
