log4j禁止标准输出

package test
import java.io.IOException

import org.apache.log4j.FileAppender
import org.apache.log4j.Level
import org.apache.log4j.Logger
import org.apache.log4j.SimpleLayout

object LoggerUtil {
  def getLogger(clazz: Class[_], fileName: String): Logger = {
		val logger = Logger.getLogger(clazz)
		logger.setLevel(Level.INFO)
		//设置是否继承父Logger,默认会有标准输出,false不会标准输出
		logger.setAdditivity(false)
		try {
			logger.addAppender(new FileAppender(new SimpleLayout(), "/tmp/prop_logs/" + fileName + ".sql"))
		} catch {
		  case e1: IOException => e1.printStackTrace()
		}
		return logger
	}
}

logger.setAdditivity(false)可以关闭标准输出
