SpringBoot项目遇到的问题

1。import org.springframework.web.socket.config.annotation.AbstractWebSocketMessageBrokerConfigurer弃用

解决：改用import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;

并且将配置类需要继承的extends AbstractWebSocketMessageBrokerConfigurer改为

            implements WebSocketMessageBrokerConfigurer
