利用Java获取文件名、类名、方法名和行号的方法小结

public static int getLineNumber( ){
  StackTraceElement[] stackTrace = new Throwable().getStackTrace();

  return stackTrace[1].getLineNumber( );
}

public static String getMethodName( ){
  StackTraceElement[] stackTrace = new Throwable().getStackTrace();

  return stackTrace[1].getMethodName( );
}

public static String getFileName( ){
  StackTraceElement[] stackTrace = new Throwable().getStackTrace();

  return stackTrace[1].getFileName( );
}

public static String getClassName( ){
  StackTraceElement[] stackTrace = new Throwable().getStackTrace();

  return stackTrace[1].getClassName();
}
