Springboot报错：Exception in thread "main" java.lang.IllegalArgumentException: LoggerFactory is not a L

报错

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:/Users/leesin/.m2/repository/org/slf4j/slf4j-log4j12/1.5.11/slf4j-log4j12-1.5.11.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
