产生此错误的原因：logback-classic包和slf4j包冲突。

解决方法：

找到哪个依赖引入了logback-classic,然后用依赖排除标签排除掉。

spring-boot-starter-log4j2和spring-boot-starter-logging同时存在会产生冲突_spring

找到了，然后：

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId>  <exclusions> <exclusion> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> </exclusion> </exclusions> </dependency>
