本文详细解析了在项目中引入Log4j和SLF4J导致的日志框架冲突问题，提供了具体的POM文件配置示例，并指导如何通过调整依赖关系来解决此类冲突，确保日志记录的一致性和项目的顺利运行。

Exception in thread "main" 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.impl.Log4jLoggerFactory loaded from file:/F:/repository/org/slf4j/slf4j-log4j12/1.7.25/slf4j-log4j12-1.7.25.jar). If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Log4jLoggerFactory

pom文件日志文件冲突

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
</dependency>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>2.0.0-alpha1</version>
</dependency>

一般正常情况下不会出现这种报错,删掉一个就好
