我的项目使用Slf4j版本1.7.25和spring-boot-starter-log4j2 v1.5.21.RELEASE。我已经配置了带有删除操作的 log4j2.xml 文件。删除似乎根本不起作用。我尝试添加
<configuration status="trace">
但它不显示任何与路径相关的错误日志。
这是日志输出:
2019-05-25 18:41:20,124 main DEBUG Building Plugin[name=Delete, class=org.apache.logging.log4j.core.appender.rolling.action.DeleteAction].

日志文件正在按预期生成，并具有在运行时提供的适当名称，并且滚动也正在运行。只是删除没有发生。
此外，如果我需要添加更多信息，请告诉我。
更新解决方案:
“/”正斜杠是我提到要删除的路径中的问题。删除它修复了它。但我仍然想知道为什么它没有出现在日志中。
最佳答案
我有一个小应用程序来尝试使用删除操作。到目前为止，它对我有用。
请参阅 https://github.com/bigzidane/spring-boot-delete-log 中的示例。检查 READMe.md 以查看之前的日志是如何删除的。
请在您的 log4j 配置 ( <Configuration status="TRACE" monitorInterval="30"> ) 中启用 TRACE，只需跟踪您在我的 README.md 文件中看到的日志，它将帮助您检测删除操作对您不起作用的原因。
可能是你设置的路径不对(可能是我这里不正确)，但是有了TRACE选项我相信你可以自己查到信息。
