【问题讨论】：

您确定要将日志写入标准输出吗？
我猜，相应的 log4j 文件本身并没有被选中，所以没有进一步的日志被打印
这能回答你的问题吗 - stackoverflow.com/questions/40762547/…
@RakeshGupta 由于安全原因，我已经替换了某些部分
@RakeshGupta，这个链接有帮助。我的 log4j2 文件中缺少记录器。非常感谢。你拯救了我的一天。很多东西要学！！

【解决方案1】：

@Rakesh Gupta 的回答解决了我的问题。 Pod 已启动，问题是未设置日志记录级别，我认为 Pod 本身有问题。作为这个项目的新手，我错过了检查日志级别的要点这是否回答了您的问题 - stackoverflow.com/questions/40762547/... -
