QUESTION:SpringBoot中Dubbo以及Zookeeper依賴包衝突?

出現以下異常： 

Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation (class org.slf4j.impl.Log4jLoggerFactory loaded from file:/C:/Users/zhanggong004/.m2/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory

當前使用的是org裏的包，正常的日誌打印需要的是logback的包。

ANSWER:

在原有的包後註明不再使用slf4j-log4j12方法。
