使用方法:-

 StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
 stackTraceElement e = stacktrace[2];//maybe this number needs to be corrected
 System.out.println(e.getMethodName());

方法示例代码的调用者在这里:-

public class TestString {

    public static void main(String[] args) {
        TestString testString = new TestString();
        testString.doit1();
        testString.doit2();
        testString.doit3();
        testString.doit4();
    }

    public void doit() {
        StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
        StackTraceElement e = stacktrace[2];//maybe this number needs to be corrected
        System.out.println(e.getMethodName());
    }

    public void doit1() {
        doit();
    }

    public void doit2() {
        doit();
    }

    public void doit3() {
        doit();
    }

    public void doit4() {
        doit();
    }
}

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.PrintWriter;

class DBConnection {
    String createdBy = null;

    DBConnection(Throwable whoCreatedMe) {
        ByteArrayOutputStream os = new ByteArrayOutputStream();
        PrintWriter pw = new PrintWriter(os);
        whoCreatedMe.printStackTrace(pw);
        try {
            createdBy = os.toString();
            pw.close();
            os.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

public class ThrowableTest {

    public static void main(String[] args) {

        Throwable createdBy = new Throwable(
                "Connection created from DBConnectionManager");
        DBConnection conn = new DBConnection(createdBy);
        System.out.println(conn.createdBy);
    }
}

OR

public static interface ICallback<T> { T doOperation(); }


public class TestCallerOfMethod {

    public static <T> T callTwo(final ICallback<T> c){
        // Pass the object created at callee to the caller
        // From the passed object we can get; what is the callee name like below.
        System.out.println(c.getClass().getEnclosingMethod().getName());
        return c.doOperation();
    }

    public static boolean callOne(){
        ICallback callBackInstance = new ICallback(Boolean){
            @Override
            public Boolean doOperation() 
            {
                return true;
            }
        };
        return callTwo(callBackInstance);
    }

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

Java 9 - JEP 259:栈遍历API

JEP 259为堆栈遍历提供了一个有效的标准API，允许对堆栈跟踪中的信息进行轻松过滤和延迟访问。在栈遍历API之前，访问栈帧的常见方法有:

的数组返回 包含类名和方法的StackTraceElement对象 每个堆栈跟踪元素的名称。 SecurityManager::getClassContext是一个受保护的方法 SecurityManager的子类来访问类上下文。 JDK-internal sun.reflect。Reflection::getCallerClass方法，你不应该使用它

使用这些api通常效率很低:

这些api要求VM急切地捕获整个快照 堆栈，它们返回表示整个堆栈的信息。 没有办法避免检查所有帧的代价，如果 调用者只对堆栈上的前几帧感兴趣。

为了找到直接调用者的类，首先获取一个StackWalker:

StackWalker walker = StackWalker
                           .getInstance(StackWalker.Option.RETAIN_CLASS_REFERENCE);

然后调用getCallerClass():

Class<?> callerClass = walker.getCallerClass();

或者遍历StackFrame并获得前面的第一个StackFrame:

walker.walk(frames -> frames
      .map(StackWalker.StackFrame::getDeclaringClass)
      .skip(1)
      .findFirst());

     /**
       * Get the method name for a depth in call stack. <br />
       * Utility function
       * @param depth depth in the call stack (0 means current method, 1 means call method, ...)
       * @return method name
       */
      public static String getMethodName(final int depth)
      {
        final StackTraceElement[] ste = new Throwable().getStackTrace();

        //System. out.println(ste[ste.length-depth].getClassName()+"#"+ste[ste.length-depth].getMethodName());
        return ste[ste.length - depth].getMethodName();
      }

例如，如果你试图获得用于调试目的的调用方法行，你需要通过编写这些静态方法的Utility类: (旧的java1.4代码，只是为了说明StackTraceElement的潜在用法)

        /**
          * Returns the first "[class#method(line)]: " of the first class not equal to "StackTraceUtils". <br />
          * From the Stack Trace.
          * @return "[class#method(line)]: " (never empty, first class past StackTraceUtils)
          */
        public static String getClassMethodLine()
        {
            return getClassMethodLine(null);
        }

        /**
          * Returns the first "[class#method(line)]: " of the first class not equal to "StackTraceUtils" and aclass. <br />
          * Allows to get past a certain class.
          * @param aclass class to get pass in the stack trace. If null, only try to get past StackTraceUtils. 
          * @return "[class#method(line)]: " (never empty, because if aclass is not found, returns first class past StackTraceUtils)
          */
        public static String getClassMethodLine(final Class aclass)
        {
            final StackTraceElement st = getCallingStackTraceElement(aclass);
            final String amsg = "[" + st.getClassName() + "#" + st.getMethodName() + "(" + st.getLineNumber()
            +")] <" + Thread.currentThread().getName() + ">: ";
            return amsg;
        }

     /**

      public static StackTraceElement getCallingStackTraceElement(final Class aclass)

      static private StackTraceElement onClassfound(Class aclass, String className, StackTraceElement st)

          StackTraceElement   resst = null;
          if(aclass != null && aclass.getName().equals(className) == false)
          {
              resst = st;
          }
          if(aclass == null)

              resst = st;
          }
          return resst;
      }

使用方法:-

 StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
 stackTraceElement e = stacktrace[2];//maybe this number needs to be corrected
 System.out.println(e.getMethodName());

方法示例代码的调用者在这里:-

public class TestString {

    public static void main(String[] args) {
        TestString testString = new TestString();
        testString.doit1();
        testString.doit2();
        testString.doit3();
        testString.doit4();
    }

    public void doit() {
        StackTraceElement[] stacktrace = Thread.currentThread().getStackTrace();
        StackTraceElement e = stacktrace[2];//maybe this number needs to be corrected
        System.out.println(e.getMethodName());
    }

    public void doit1() {
        doit();
    }

    public void doit2() {
        doit();
    }

    public void doit3() {
        doit();
    }

    public void doit4() {
        doit();
    }
}

这个方法做同样的事情，但更简单一点，可能性能更好一点，在你使用反射的情况下，它会自动跳过那些帧。唯一的问题是它可能不会出现在非sun的jvm中，尽管它包含在JRockit 1.4—>1.6的运行时类中。(重点是，它不是一个公共类)。

sun.reflect.Reflection

    /** Returns the class of the method <code>realFramesToSkip</code>
        frames up the stack (zero-based), ignoring frames associated
        with java.lang.reflect.Method.invoke() and its implementation.
        The first frame is that associated with this method, so
        <code>getCallerClass(0)</code> returns the Class object for

        frames skipped. */
    public static native Class getCallerClass(int realFramesToSkip);

至于realFramesToSkip的值应该是什么，Sun 1.5和1.6虚拟机版本的java.lang. lang. js。系统中，有一个名为getCallerClass()的包保护方法，它调用sun.reflect. reflect. getCallerClass(3)，但在我的助手实用程序类中，我使用了4，因为有添加的助手类调用的帧。
