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:/D:/maven/repository/org/slf4j/slf4j-log4j12/1.7.30/slf4j-log4j12-1.7.30.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含义

这个错误信息表示你的项目中Logback和Log4j发生了冲突。两个日志框架都在classpath中,但是LoggerFactory不是Logback LoggerContext。为了解决这个问题,你应该从项目中删除Logback或Log4j,具体取决于你更喜欢使用哪个日志框架。或者,如果你正在使用WebLogic,你可以通过将'org.slf4j'添加到WEB-INF/weblogic.xml的prefer-application-packages中来优先使用Log4j。org.slf4j.impl.Log4jLoggerFactory是Log4j的一个实现类,它与Logback发生冲突导致了这个错误。

LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation
日志错误信息中的“LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. Either remove Logback or the competing implementation”表示日志工厂(LoggerFactory)不是Logback的LoggerContext,但是Logback在类路径上存在。这意味着存在与Logback冲突的其他日志实现。
解决这个问题有两种方法:
1. 移除Logback:您可以从项目的依赖中移除Logback,这样就不会与其他日志实现发生冲突了。
2. 排除冲突实现:如果您希望继续使用Logback,而且需要解决与其他实现的冲突,可以通过在项目的依赖配置中排除冲突实现来解决。例如,在Maven项目中,您可以使用<exclusions>标签来排除冲突的实现,如上文引用中所示。
如果您正在使用WebLogic服务器,还需要将'org.slf4j'添加到WEB-INF/weblogic.xml文件的prefer-application-packages中,以解决这个问题。
请根据您的实际需求选择适合的解决方案。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

loggerfactory is not a logback loggercontext but logback is on the classpath. either remove logback or the competing implementation
这句话的意思是:loggerfactory不是logback的loggercontext,但是logback在classpath中。要么移除logback,要么移除竞争的实现。
简单来说,就是说loggerfactory和logback不兼容,但是logback又被引入了。所以要么移除logback,要么移除与之竞争的实现。
