为什么我会收到来自 Log4J 1.2.17 的警告?我正在尝试在我的 java 项目中使用 log4j,但我不断收到以下警告。有人可以告诉我为什么吗?
警告:
log4j:WARN Continuable parsing error 2 and column 87
log4j:WARN Document root element "log4j:configuration", must match DOCTYPE root "null".
log4j:WARN Continuable parsing error 2 and column 87
log4j:WARN Document is invalid: no grammar found.
我的 log4j.xml 文件:

我知道这只是一个警告,但我想知道为什么我会得到它们并阻止它们来......谢谢
