log4j-over-slf4j.jar和slf4j-log4j12.jar conflitct ...但我沒有log4j-over-slf4j

Question

我在我的maven項目中使用帶有log4j的SLF4J。當我在eclipse中的tomcat中運行項目時，以及在使用tomcat maven插件的maven中一切正常。

但是當我把戰爭放在我的tomcat生產服務器上時，項目不啓動，給我這個錯誤。

java.lang.IllegalStateException：檢測到的類路徑上都log4j的環比slf4j.jar 和約束SLF4J-log4j12.jar，搶佔 的StackOverflowError。有關更多詳細信息，另請參閱 http://www.slf4j.org/codes.html#log4jDelegationLoop。

我已經看到了很多關於這個錯誤的stackoverflow的答案，我已經明白我需要排除衝突的jar。問題是我沒有log4j-over-slf4j在我的項目中... .war的lib文件夾不包含這個jar，並且問題僅在我的生產服務器的tomcat服務器中存在。我不知道該怎麼辦。我在這裏放置我的依賴樹。

編輯：

經過很多很多很多其他的測試，這個問題只與我的生產服務器的tomcat發生，我部署在其他8臺服務器和系統運行正常。我想這是與我的生產服務器tomcat中運行的其他項目的衝突。可以這樣做嗎？

Answer 1

你應該在tomcat/lib文件夾中有一個log4j-over-slf4j.jar。你檢查過了嗎？
