LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation

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.helpers.NOPLoggerFactory loaded from file:/Users/jack/.m2/repository/org/slf4j/slf4j-api/1.7.25/slf4j-api-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.helpers.NOPLoggerFactory

大概就是说Logback已经在classpath中存在，这时候就应该意识到有Logback依赖冲突，在多个地方都有Logback的依赖。
