如何在Eclipse中屏蔽日志

//屏蔽日志 Eclipse Java

import org.apache.log4j.Level;

import org.apache.log4j.Logger;

Logger.getLogger("org.apache.spark").setLevel(Level.WARN);

Logger.getLogger("org.eclipse.jetty.server").setLevel(Level.OFF);

//Scala 屏蔽日志与在Java中是一样的

import org.apache.log4j.{Level, Logger} 
Logger.getLogger("org.apache.spark").setLevel(Level.WARN)

Logger.getLogger("org.eclipse.jetty.server").setLevel(Level.OFF)
