使用System.Logger

System.Logger
getName()
isLoggable()
log() 只用了String方法，其他的先放着

System.Logger log = System.getLogger("asd");
		System.out.println(log.getName());
		System.out.println("ALL:"+log.isLoggable(System.Logger.Level.ALL));
		System.out.println("FINER:"+log.isLoggable(System.Logger.Level.TRACE));
		System.out.println("FINE:"+log.isLoggable(System.Logger.Level.DEBUG));
		System.out.println("INFO:"+log.isLoggable(System.Logger.Level.INFO));
		System.out.println("WARNING:"+log.isLoggable(System.Logger.Level.WARNING));
		System.out.println("SEVERE:"+log.isLoggable(System.Logger.Level.ERROR));
		System.out.println("OFF:"+log.isLoggable(System.Logger.Level.OFF));

		log.log(System.Logger.Level.INFO,"他们都是傻逼，都是傻逼");
		log.log(System.Logger.Level.WARNING,"他们都是傻逼，都是傻逼");
		log.log(System.Logger.Level.ERROR,"他们都是傻逼，都是傻逼");
		log.log(System.Logger.Level.OFF,"他们都是傻逼，都是傻逼");
