日志系统无法使用来自“null”的配置进行初始化 java.lang.IllegalStateException：检测到 Logback 配置错误：

Question

我想在我的 logback-spring.xml 中使用一个通用的 xml？如何在 logback-spring.xml 中包含 xml 而不会出错。我得到了在我们需要使用的 logback-spring.xml 中包含一个 xml，但不知何故这对我不起作用。我投入了很多时间，但没有结果。 https://dennis-xlc.gitbooks.io/the-logback-manual/content/en/chapter-3-configuration/configuration-file-syntax/file-inclusion.html

必须在 logback-spring.xml 中使用的文件不能包含<xml> 标签。该文件应如下所示。 <included> 标记必须用于必须加载到另一个文件中的文件。

    <included>
            <property name="LOGS" value="./logs" />
            <property resource ="application.yml"/>
