                com.mysql.jdbc.Driver
                             
               
                jdbc:mysql://127.0.0.1:3306/databaseName
                             
               
                root
                             
               
                root
                                      -->
              
             
            
           
          
         
        
       
      
     
    

代码中使用方法：

protected Logger logger = LoggerFactory.getLogger(this.getClass());logger.info("XXXXXXXXXXXX");logger.debuglogger.errorlogger.warn
