使用log4j2时获取log4j1错误

Question

我已经尝试过了：将log4j 1.x和log4j 2与依赖于log4j 1.x 的第三方库混合

当我将jar文件部署到docker映像时，我得到了一个log4j1 appender错误，但当我在Eclipse中运行主方法时没有看到。

log4j:WARN找不到记录器的附加程序(等等(。log4j:WARN请正确初始化log4j系统。log4j:警告请参阅http://logging.apache.org/log4j/1.2/faq.html#noconfig了解更多信息。

以下是我的依赖

我已经尝试删除所有可能引用log4j1进行编译和测试的内容(包括log4j-1.2-api((除了在我的代码中删除对slf4j的引用和使用log4j-api之外(，但没有成功。

我启动jar文件的命令是：

java -Dlog4j.configurationFile=$LOGGING_CFG -Ddatacollector.config.dir=$CONFIG_DIR -jar blah.jar

我验证了我的参数是否有效，并确保配置在IDE中有效。我甚至尝试用Configurator.initialize(name，filePath(编程加载文件。我怀疑log4j1在我的环境中，我想把它清除掉。

谢谢你的帮助。

我通过将maven汇编插件版本更新到3.1.1解决了这个问题。
