在方法内部获得调用者信息

相关的实现思路,过程跟log4j异曲同工,不错!!


public static String getCaller ( ) {
    int i;
    StackTraceElement stack [ ] = ( new Throwable ( ) ). getStackTrace ( );
    for (i= 0; i < stack. length; i++ ) {
      StackTraceElement ste=stack [i ];
        System. out. println (ste. getClassName ( )+"."+ste. getMethodName ( )+" (... )" );
       System. out. println (i+"--"+ste. getMethodName ( ) );
       System. out. println (i+"--"+ste. getFileName ( ) );
       System. out. println (i+"--"+ste. getLineNumber ( ) );
    }
  }
