听起来好像您试图避免将this的引用传递到方法中。传递这个比通过当前堆栈跟踪查找调用者要好得多。重构为更面向对象的设计更好。你不需要认识打电话的人。必要时传递回调对象。

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();
    }
}

下面是我根据本主题中显示的提示制作的部分代码。 希望能有所帮助。

(请随时提出任何建议来改进此代码，请告诉我)

柜台:

public class InstanceCount{
    private static Map<Integer, CounterInstanceLog> instanceMap = new HashMap<Integer, CounterInstanceLog>();
private CounterInstanceLog counterInstanceLog;


    public void count() {
        counterInstanceLog= new counterInstanceLog();
    if(counterInstanceLog.getIdHashCode() != 0){
    try {
        if (instanceMap .containsKey(counterInstanceLog.getIdHashCode())) {
         counterInstanceLog= instanceMap .get(counterInstanceLog.getIdHashCode());
    }

    counterInstanceLog.incrementCounter();

            instanceMap .put(counterInstanceLog.getIdHashCode(), counterInstanceLog);
    }

    (...)
}

对象是:

public class CounterInstanceLog{
    private int idHashCode;
    private StackTraceElement[] arrayStackTraceElements;
    private int instanceCount;
    private String callerClassName;

    private StackTraceElement getProjectClasses(int depth) {
      if(depth< 10){
        getCallerClassName(sun.reflect.Reflection.getCallerClass(depth).getName());
        if(getCallerClassName().startsWith("com.yourproject.model")){
            setStackTraceElements(Thread.currentThread().getStackTrace());
            setIdHashCode();
        return arrayStackTraceElements[depth];
        }
        //+2 because one new item are added to the stackflow
        return getProjectClasses(profundidade+2);           
      }else{
        return null;
      }
    }

    private void setIdHashCode() {
        if(getNomeClasse() != null){
            this.idHashCode = (getCallerClassName()).hashCode();
        }
    }

    public void incrementaContador() {
    this.instanceCount++;
}

    //getters and setters

    (...)



}

注意:如果你使用Java 9或更高版本，你应该使用Ali Dehghani的回答中描述的StackWalker.getCallerClass()。

由于历史原因，下面不同方法的比较非常有趣。

可以在此请求的注释中找到替代解决方案。 它使用自定义SecurityManager的getClassContext()方法，似乎比堆栈跟踪方法快。

下面的程序测试了不同建议方法的速度(最有趣的部分是内部类SecurityManagerMethod):

/**
 * Test the speed of various methods for getting the caller class name
 */
public class TestGetCallerClassName {

  /**
   * Abstract class for testing different methods of getting the caller class name
   */
  private static abstract class GetCallerClassNameMethod {
      public abstract String getCallerClassName(int callStackDepth);
      public abstract String getMethodName();
  }

  /**
   * Uses the internal Reflection class
   */
  private static class ReflectionMethod extends GetCallerClassNameMethod {
      public String getCallerClassName(int callStackDepth) {
          return sun.reflect.Reflection.getCallerClass(callStackDepth).getName();
      }

      public String getMethodName() {
          return "Reflection";
      }
  }

  /**
   * Get a stack trace from the current thread
   */
  private static class ThreadStackTraceMethod extends GetCallerClassNameMethod {
      public String  getCallerClassName(int callStackDepth) {
          return Thread.currentThread().getStackTrace()[callStackDepth].getClassName();
      }

      public String getMethodName() {
          return "Current Thread StackTrace";
      }
  }

  /**
   * Get a stack trace from a new Throwable
   */
  private static class ThrowableStackTraceMethod extends GetCallerClassNameMethod {

      public String getCallerClassName(int callStackDepth) {
          return new Throwable().getStackTrace()[callStackDepth].getClassName();
      }

      public String getMethodName() {
          return "Throwable StackTrace";
      }
  }

  /**
   * Use the SecurityManager.getClassContext()
   */
  private static class SecurityManagerMethod extends GetCallerClassNameMethod {
      public String  getCallerClassName(int callStackDepth) {
          return mySecurityManager.getCallerClassName(callStackDepth);
      }

      public String getMethodName() {
          return "SecurityManager";
      }

      /** 
       * A custom security manager that exposes the getClassContext() information
       */
      static class MySecurityManager extends SecurityManager {
          public String getCallerClassName(int callStackDepth) {
              return getClassContext()[callStackDepth].getName();
          }
      }

      private final static MySecurityManager mySecurityManager =
          new MySecurityManager();
  }

  /**
   * Test all four methods
   */
  public static void main(String[] args) {
      testMethod(new ReflectionMethod());
      testMethod(new ThreadStackTraceMethod());
      testMethod(new ThrowableStackTraceMethod());
      testMethod(new SecurityManagerMethod());
  }

  private static void testMethod(GetCallerClassNameMethod method) {
      long startTime = System.nanoTime();
      String className = null;
      for (int i = 0; i < 1000000; i++) {
          className = method.getCallerClassName(2);
      }
      printElapsedTime(method.getMethodName(), startTime);
  }

  private static void printElapsedTime(String title, long startTime) {
      System.out.println(title + ": " + ((double)(System.nanoTime() - startTime))/1000000 + " ms.");
  }
}

运行Java 1.6.0_17的2.4 GHz英特尔酷睿2双核MacBook的输出示例:

Reflection: 10.195 ms.
Current Thread StackTrace: 5886.964 ms.
Throwable StackTrace: 4700.073 ms.
SecurityManager: 1046.804 ms.

内部反射方法比其他方法快得多。从新创建的Throwable中获取堆栈跟踪比从当前线程中获取堆栈跟踪要快。在寻找调用者类的非内部方法中，自定义SecurityManager似乎是最快的。

更新

正如lyomi在这条评论中指出的那样，sun.reflect. reflect. getcallerclass()方法在Java 7 update 40中默认被禁用，在Java 8中被完全删除。有关这方面的更多信息，请参阅本期Java错误数据库。

更新2

正如zammbi所发现的，Oracle被迫退出删除sun.reflect. reflect. getcallerclass()的更改。在Java 8中仍然可用(但已弃用)。

更新3

3年后:更新当前JVM的计时。

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();
    }
}

private void parseExceptionContents(
      final Exception exception,
      final OutputStream out)
   {
      final StackTraceElement[] stackTrace = exception.getStackTrace();
      int index = 0;
      for (StackTraceElement element : stackTrace)
      {
         final String exceptionMsg =
              "Exception thrown from " + element.getMethodName()
            + " in class " + element.getClassName() + " [on line number "

            out.write((headerTitlePortion + index++ + newLine).getBytes() );
            out.write((headerLine + newLine).getBytes());
            out.write((exceptionMsg + newLine + newLine).getBytes());
            out.write(
