		./logs
	

	
	
		
			
		
		
		
		
			


			
				
				
				
				
			

			
				
					
						
							
							
						
						
					
				
			
		
	
//异步日志，保留7天，每天翻转
	
			
			
			
			
			
				
				
			
			
			 
			   
         	 
        
			
		
	
	
	
	     
        
        
    
		
		     
        
			
			
		
	

1. 4代码：

---

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.MDC;

/**
 * Hello world!
 *
 */
public class App 
{

	 static public Logger logger = LoggerFactory.getLogger(App.class);
    public static void main( String[] args )
    {
    
    	new Thread(new Runnable() {
			
			@Override
			public void run() {
				int ii=1;
				while(true) {
//						Thread.sleep(1000);
						MDC.put("uuid", StringUtils.getUUID());
						ii++;
						logger.info( "Hello World!" );
						logger.error("haha"+ii,"haha"+ii);
	
				}
			}
		}).start();
    	
    }
}

Utils：

package com.zh.logtest;

import java.util.ArrayList;
import java.util.UUID;

public class StringUtils {
	 /** 
	    * 获得指定数目的UUID 
	    * @param number int 需要获得的UUID数量 
	    * @return String[] UUID数组 
	    */ 
	    public static ArrayList getUUID(int number){
	        ArrayList list=new ArrayList<>();
	    if(number < 1){ 
	    return null; 
	    } 
	    for(int i=0;i

标准日志输出如下：

	
	
		./logs
