java - 减少 log4j.xml 中 Tomcat Digester 记录器的冗长程度

Question

据我所知，这些模糊的日志消息与 Tomcat 的 Digester 日志记录组件相关联。有谁知道如何减少这些日志的冗长程度？

以下调试消息似乎无限期地重复，消息之间有 100-10,000 行，并且由于重复的上下文切换，我正在使用的应用程序的启动时间至少增加了 20 分钟(据我所知知道)。除了 Digester 消息外，没有任何痕迹。

这个模糊的调试消息对任何人来说看起来都正常吗？

调试消息是如何进入的？我什至不希望这些日志出现在这里。

您想减少 tomcat 日志记录，对吗？删除 logging.properties 文件。从该附加程序中，删除包含 org.apache.log4j.net.SyslogAppender 的附加程序。整个一个。这将禁用您的 tomcat 日志记录。 Info也吐出很多信息是我观察到的。
