在使用Spring Boot框架开发过程中，遇到因Logback与Log4j同时存在导致的日志工厂冲突错误。文章详细记录了错误堆栈信息，指出在Spring Boot启动时出现java.lang.IllegalArgumentException异常，提示LoggerFactory不是一个LogbackLoggerContext。为解决此问题，需移除Logback或Log4j，若在WebLogic环境中，则需在WEB-INF/weblogic.xml中添加'org.slf4j'到prefer-application-packages。

问题：新建工程busr，采用pandora boot，引入了需要的包，简单写了点代码发布，
spring-boot启动报错：

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
