LOG4J generates a separate log file for a separate class

Recent company projects need to go to the network to download pictures, according to different circumstances to save the log to a different file. Specifically, the ordinary log information output to a separate file, the picture download failed to save the log separately to another file for later backtracking.

Using the example in your application

Import Org.apache.log4j.Logger;

public class Logutil {
	private static Logger Clogger = Logger.getlogger ("Commonlog");
	private static Logger Elogger = Logger.getlogger ("ErrorLog");
	
	public static void Downerror (Class clz,string message) {
		elogger.error (message+ "[" +clz.getname () + "]");
	}
	
	public static void info (Class clz,string message) {
		clogger.info (message+ "[" +clz.getname () + "]");
	}
	
	public static void Debug (Class clz,string message) {
		clogger.debug (message+ "[" +clz.getname () + "]");
	}
	
	public static void Warn (Class clz,string message) {
		Clogger.warn (message+ "[" +clz.getname () + "]");
	}
	
	public static void error (Class clz,string message) {
		clogger.error (message+ "[" +clz.getname () + "]");
	}

Here's the Commonlog, Errorlog is configured in the log4j configuration file.
