Question

我的项目使用Slf4j版本1.7.25和spring-boot-starter-log4j2 v1.5.21.RELEASE。我已经用Delete操作配置了一个log4j2.xml文件。删除似乎根本不起作用。我尝试添加

<configuration status="trace">

但是它没有显示与路径有关的任何错误日志。

以下是日志输出：

2019-05-25 18:41:20,124 main DEBUG Building Plugin[name=Delete, class=org.apache.logging.log4j.core.appender.rolling.action.DeleteAction].

也请在下面查看我的配置xml文件

正在使用适当的名称生成日志文件，该名称在运行时提供，并且滚动也可以正常进行。仅删除未发生。

另外，如果需要添加其他信息，请告诉我。

更新解决方案：

我提到的要删除的路径中的问题是“ /”正斜杠。删除它修复了它。但是我仍然想知道为什么它没有出现在日志中。

Answer 1

我有一个小型应用程序，尝试使用Delete动作。到目前为止，它对我有用。

请参见https://github.com/bigzidane/spring-boot-delete-log上的示例。检查READMe.md以查看以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，这将帮助您仅遵循在README.md文件中看到的日志，即可检测出删除操作对您不起作用的原因。

它可能来自您设置错误的路径（也许我在这里不正确），但是使用TRACE选项，我相信您可以自己找到信息。
