springboot MDC 日志线程标识

 

MDC是线程级别的

1、监听器

@WebListener
public class LogListener implements ServletRequestListener {

    private final Logger log = LoggerFactory.getLogger(this.getClass());

    @Override
    public void requestDestroyed(ServletRequestEvent servletRequestEvent) {
        MDC.clear();
    }

    @Override
    public void requestInitialized(ServletRequestEvent servletRequestEvent) {
        String mdcseq = RandomStringUtils.randomNumeric(16);
        MDC.put("mdcseq", mdcseq);
    }
}

2、logback.xml 放在 resources下

    
    
    
    
        
            ${LOG_FILE}-%d{yyyy-MM-dd}.%i.log}
            100MB
            360
            50GB
        
        
            ${MY_FILE_LOG_PATTERN}
            utf8
        
    

    
        
            ${MY_FILE_LOG_PATTERN}
            utf8
        
    

    
        
        
    

3、启动器注解：@ServletComponentScan(basePackages = {"com.*"})

4、日志前显示当前线程序号
