是否有一种方法来获得Java中当前正在执行的方法的名称?


当前回答

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

Name的值为foo。

其他回答

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

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);

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())}));
    }
}
MethodHandles.lookup().lookupClass().getEnclosingMethod().getName();

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
    }
}
