Java gets the implementation code for the current function name

Without further ado, go straight to the code

import java.text.SimpleDateFormat; 
import java.util.Date; 
/** 
* Java Achieve similar C/C++ In the __FILE__ , __FUNC__ , __LINE__ Etc. , Mainly used for logging and other functions.  
* 
* @version 1.0  
* 
*/ 
public abstract class CommonFunction {

StringBuffer toStringBuffer = new StringBuffer("[").append( 
traceElement.getFileName()).append(" | ").append( 
traceElement.getLineNumber()).append(" | ").append( 
traceElement.getMethodName()).append("]"); 
return toStringBuffer.toString(); 
} 
//Current file name
public static String _FILE_() { 
StackTraceElement traceElement = ((new Exception()).getStackTrace())[1]; 
return traceElement.getFileName(); 
} 
//Current method name
public static String _FUNC_() {

return traceElement.getMethodName(); 
} 
//The current line number
public static int _LINE_() { 
StackTraceElement traceElement = ((new Exception()).getStackTrace())[1];
