我寫了這個pom.xml
基於春季啓動樣本。如何解決各種log4j軟件包衝突?
當我開始我的應用程序,我得到這個錯誤:
SLF4J: Detected both log4j-over-slf4j.jar AND bound slf4j-log4j12.jar on the class path, preempting StackOverflowError.
我完全新的Java和Maven的,並堅持在這裏相當長一段時間。
我試圖在dependency
中寫一些exclusions
。但它沒有解決。我不知道應該從哪個包中排除哪個包。如果是這樣,依賴的包裹怎麼能正常工作?

什麼是你用來運行你的應用程序的容器(服務器)? –
考慮關於spring引導日誌的[post](https://docs.spring.io/spring-boot/docs/current/reference/html/howto-logging.html)。這也是一個很好的[示例](https://www.mkyong.com/spring-boot/spring-boot-slf4j-logging-example/)。 –
