Util.java:

public static String getCurrentClassAndMethodNames() {
    final StackTraceElement e = Thread.currentThread().getStackTrace()[2];
    final String s = e.getClassName();
    return s.substring(s.lastIndexOf('.') + 1, s.length()) + "." + e.getMethodName();
}

SomeClass.java:

public class SomeClass {
    public static void main(String[] args) {
        System.out.println(Util.getCurrentClassAndMethodNames()); // output: SomeClass.main
    }
}

我有解决方案使用这个(在Android)

/**
 * @param className       fully qualified className
 *                        <br/>
 *                        <code>YourClassName.class.getName();</code>
 *                        <br/><br/>
 * @param classSimpleName simpleClassName
 *                        <br/>
 *                        <code>YourClassName.class.getSimpleName();</code>
 *                        <br/><br/>
 */
public static void getStackTrace(final String className, final String classSimpleName) {
    final StackTraceElement[] steArray = Thread.currentThread().getStackTrace();
    int index = 0;
    for (StackTraceElement ste : steArray) {
        if (ste.getClassName().equals(className)) {
            break;
        }
        index++;
    }
    if (index >= steArray.length) {
        // Little Hacky
        Log.w(classSimpleName, Arrays.toString(new String[]{steArray[3].getMethodName(), String.valueOf(steArray[3].getLineNumber())}));
    } else {
        // Legitimate
        Log.w(classSimpleName, Arrays.toString(new String[]{steArray[index].getMethodName(), String.valueOf(steArray[index].getLineNumber())}));
    }
}

我把maklemenz的回答重写了一下

private static Method m;

static {
    try {
        m = Throwable.class.getDeclaredMethod(
            "getStackTraceElement",
            int.class
        );
    }
    catch (final NoSuchMethodException e) {
        throw new NoSuchMethodUncheckedException(e);
    }
    catch (final SecurityException e) {
        throw new SecurityUncheckedException(e);
    }
}


public static String getMethodName(int depth) {
    StackTraceElement element;

    final boolean accessible = m.isAccessible();
    m.setAccessible(true);

    try {
        element = (StackTraceElement) m.invoke(new Throwable(), 1 + depth);
    }
    catch (final IllegalAccessException e) {
        throw new IllegalAccessUncheckedException(e);
    }
    catch (final InvocationTargetException e) {
        throw new InvocationTargetUncheckedException(e);
    }
    finally {
        m.setAccessible(accessible);
    }

    return element.getMethodName();
}

public static String getMethodName() {
    return getMethodName(1);
}

String methodName =Thread.currentThread().getStackTrace()[1].getMethodName();
System.out.println("methodName = " + methodName);

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。

使用以下代码:

    StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
    StackTraceElement e = stacktrace[1];//coz 0th will be getStackTrace so 1st
    String methodName = e.getMethodName();
    System.out.println(methodName);
