springboot 日誌問題記錄

問題：新建工程busr，採用pandora boot，引入了須要的包，簡單寫了點代碼發佈，
spring-boot啓動報錯：

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 
jar:file:/opt/**.jar!/BOOT-INF/lib/log4j-slf4j-impl-2.6.2.jar!/). If you are using WebLogic you will need to add 'org.slf4j' 
to prefer-application-packages in WEB-INF/weblogic.xml Object of class [org.apache.logging.slf4j.Log4jLoggerFactory] 
must be an instance of class ch.qos.logback.classic.LoggerContext
