基于slf4j实现多线程日志

对于多线程的程序来说，排错是一件特别麻烦的事情，特别是针对日志，多线程有可能发生日志写阻塞，那我们有没有可能每一个线程一个日志文件呢？答案是可以的，基于slf4j的MDC，具体MDC原理各位看官自行百度

直接上代码

/**
 * Created by shengjk1 on 2017/11/30
 */
public class Main {
	protected final static org.slf4j.Logger logger = LoggerFactory.getLogger(Main.class);
	
	public static void main(String[] args) {
		String[] destinations = {"a","b","c"};
		logger.info("开始启动  ");
		Thread thread=null;
		for (final String destination:destinations ) {
			thread=new Thread(new Runnable() {
				@Override
				public void run() {
					MDC.put("logFileName", destination);
					//自己要运行的代码如  ClusterCanalClient.run(destination);
					MDC.remove("logFileName");
				}
			});
			thread.setName(destination);
			thread.start();
		}
	}
}

logback.xml

    

    
    
        
            %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
        
    

    
    
    
        
            logFileName
            logback
        
        
            
            
            <-以logFileName开头的log文件->
                ${log.path}/${logFileName}.log
                
                    
                        %d{yyyy-MM-dd HH:mm:ss.SSS} %mdc [%thread] %-5level %logger{36} - %msg%n
                    
                
                
                
                
                
                
                
                
                    
                    ${log.path}/${logFileName}.%d{yyyy-MM-dd}.log
                    
                    30
