產生此錯誤的原因:logback-classic包和slf4j包衝突。
解決方法:
找到哪個依賴引入了logback-classic,然後用依賴排除標籤排除掉。
找到了,然後:
<!--springboot-websocket服務--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> <!--排除--> <exclusions> <exclusion> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> </exclusion> </exclusions> </dependency>
