LoggerFactory is not a Logback LoggerContext but Logback is on the classpath（springboot项目部署到tomcat报）

springboot项目部署到tomcat报错误

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.apache.logging.slf4j.Log4jLoggerFactory loaded from file:/data/website/magic-api/WEB-INF/lib/log4j-slf4j-impl-2.7.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.apache.logging.slf4j.Log4jLoggerFactory

错误代码：
