Java Log4j2-为什么不'；t已注册自定义级别

我正在学习log4j2。我试图编写一个在xml配置文件中定义的自定义级别过滤器的示例

由于某种原因，他们似乎没有被认出

为什么不能识别自定义级别？

---

我希望自定义级别能够被识别。以及要根据其intLevel“附加”的记录事件。

我没有得到官方支持的答案。但是根据前面的测试，为了使配置文件中定义/声明的级别可用，必须满足两个条件

该级别的名称必须为ALL CAPITAL，才能在配置文件中使用。（这也适用于配置文件中使用的java定义的级别）

必须至少调用一个记录器（使用

LogManager.getLogger（“logger\u name”）

或

LogManager.getRootLevel（）

）才能在java代码中注册和使用所有级别。在尝试使用任何配置文件定义的级别筛选器之前，必须调用记录器
