Java 如果您使用的是WebLogic，则需要添加'；org.slf4j'；选择WEB-INF/weblogic.xml中的应用程序包：org.slf4j.impl.Log4jLoggerFactory

Maven生成错误：

Caused by: 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/ravisut/.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

调用

mvn dependency:tree

查看谁正在导入logback，谁正在导入slf4j-log4j，然后排除您不想要的一个。

@YMomb我猜是“我如何才能摆脱此异常”。
