一、java自带log:java.util.logging.Logger使用三步曲

public class HelloLogWorld {     private static String name = HelloLogWorld.class.getName();         private static Logger log = Logger.getLogger(name);// <= (2)     public void sub() {       log.info("Hello Logging World");    // <= (3)     }     public static void main(String[] args) {       HelloLogWorld logWorld = new HelloLogWorld();       logWorld.sub();     }   }

 

二、使用 org.apache.log4j.Logger;

具体代码：

Logger logger=Logger.getLogger(ECntrCbsChargingService.class);logger.info("success");
