问题 I am using slf4j-log4j12 latest version 1.7.25. We are using kibana to view logs, but the Kibana fails to read logs from tomcat. I need to set filePermissions to read files from tomcat in log4j.properties file. filePermissions="rw-r-----" My log4j.properties file, # Put log messages in rolling log file log4j.rootLogger=info, file log4j.logger.com.sample=debug log4j.appender.file=org.apache.log4j.DailyRollingFileAppender log4j.appender.file.File=logs/MyService.log log4j.appender.file

JAR冲突问题的解决

今天碰到群里小伙伴问，线上程序好像有多个不同版本的Netty包，怎么去看到底加载了哪一个? 在说如何看之前，先来说说，当你开始意识到项目里有多个不同版本的Jar包，都是因为遇到了这几个异常： 1、java.lang.NoSuchMethodException：自己代码中调用了某个方法，因为加载了其他版本的jar，这个版本正好没这个方法。 2、java.lang.NoClassDefFoundError：编译时候是好的，但是运行的时候，因为加载的jar版本问题，没有这个类。 3、java.lang.ClassNotFoundException：在动态加载某个Class的时候，因为要加载的jar不是正确的版本，而导致找不到这个类。 当你在本地运行ok，但到服务器上发现出现这些错误的时候，就要意识到很可能是jar冲突了(有相同依赖存在多个版本)。这个问题往往也会有这样的表现：多实例部署的时候，有的实例是好的，有的实例则不行。 查看加载的类和方法 根据之前分析的异常种类，我们可以去运行中的现场确认当前加载的问题。 这里我们可以使用阿里开源的Arthas工具，如果第一次用，那么按下面操作先安装再运行： curl -O https://arthas.aliyun.com/arthas-boot.jar java -jar arthas-boot.jar 运行好之后

Stop displaying logger output to console from dependencies

由 半城伤御伤魂 提交于 2021-02-08 06:21:37
问题 I am new to log4j hence asking SOs help. In my Java project I have couple of Maven dependencies which clutter the console output with redundant log info. I want to disable such logging. I understand setting additivity property to false might help. But could not use it properly. I am looking for a log4j.xml config which will only print log output (warn, error ..) from my project and not from any dependencies. 回答1: Redirect all the third party lib logs in a target appender, use another appender
