这是对virgo47的答案(如上)的扩展。

它提供了一些静态方法来获取当前和调用类/方法名。

/* Utility class: Getting the name of the current executing method 
 * https://stackoverflow.com/questions/442747/getting-the-name-of-the-current-executing-method
 * 
 * Provides: 
 * 
 *      getCurrentClassName()
 *      getCurrentMethodName()
 *      getCurrentFileName()
 * 
 *      getInvokingClassName()
 *      getInvokingMethodName()
 *      getInvokingFileName()
 *
 * Nb. Using StackTrace's to get this info is expensive. There are more optimised ways to obtain
 * method names. See other stackoverflow posts eg. https://stackoverflow.com/questions/421280/in-java-how-do-i-find-the-caller-of-a-method-using-stacktrace-or-reflection/2924426#2924426
 *
 * 29/09/2012 (lem) - added methods to return (1) fully qualified names and (2) invoking class/method names

Thread.currentThread().getStackTrace()通常会包含你调用它的方法，但有陷阱(参见Javadoc):

在某些情况下，一些虚拟机可能会从堆栈跟踪中省略一个或多个堆栈帧。在极端情况下，允许没有关于此线程的堆栈跟踪信息的虚拟机从此方法返回零长度数组。

这可以使用StackWalker自Java 9。

public static String getCurrentMethodName() {
    return StackWalker.getInstance()
                      .walk(s -> s.skip(1).findFirst())
                      .get()
                      .getMethodName();
}

public static String getCallerMethodName() {
    return StackWalker.getInstance()
                      .walk(s -> s.skip(2).findFirst())
                      .get()
                      .getMethodName();
}

StackWalker被设计成懒惰的，所以它可能比Thread更有效。getStackTrace，它为整个调用堆栈急切地创建一个数组。更多信息请参见JEP。

这里的大多数答案似乎都是错的。

    public static String getCurrentMethod() {
            return getCurrentMethod(1);
    }
    public static String getCurrentMethod(int skip) {
            return Thread.currentThread().getStackTrace()[1 + 1 + skip].getMethodName();
    }

例子:

    public static void main(String[] args) {
            aaa();
    }

    public static void aaa() {
            System.out.println("aaa  -> "  + getCurrentMethod( ) );
            System.out.println("aaa  -> "  + getCurrentMethod(0) );
            System.out.println("main -> "  + getCurrentMethod(1) );
    }

输出:

aaa  -> aaa
aaa  -> aaa
main -> main

这两个选项都适合我使用Java:

new Object(){}.getClass().getEnclosingMethod().getName()

Or:

Thread.currentThread().getStackTrace()[1].getMethodName()

 public class SomeClass {
   public void foo(){
      class Local {};
      String name = Local.class.getEnclosingMethod().getName();
   }
 }

Name的值为foo。
