是否可以使用Log4J仅记录一个级别的消息 [英] Is it possible to log only one level messages with Log4J

问题描述

如果我将日志级别设置为DEBUG，则将记录/打印所有日志级别> = DEBUG的消息。
但是我可以将日志级别设置为仅DEBUG，以便打印仅具有DEBUG的日志级别的消息。或者可以给出一个范围，比如打印日志级别> = DEBUG但是<错误？

If I set the log level to DEBUG, All messages with log level >= DEBUG will be logged/printed. But can I set log level to only DEBUG, such that messages with log level only with DEBUG will be printed. Or can give a range like print all messages whose log level is >=DEBUG but < ERROR?

推荐答案

也许你可以使用LevelMatchFilter？
