本文主要是介绍SpringBoot引入WebSocket依赖报ServerContainer no avaliable，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1、WebSocketConfig 文件报错
@Configuration
@EnableWebSocket
public class WebSocketConfig {@Beanpublic ServerEndpointExporter serverEndpointExporter() {return new ServerEndpointExporter();}
2、报错内容

3、排查步骤
1）第一次排查时只以为时jar冲突问题，以为时引入的封装好的jar包与srping-boot-websocket加入冲突
将引入的dep依赖排除发现启动也报错
2）跟踪报错的源码如下：serverContriner不能为null
点击ServerContainer发现他有很多依赖来自不同的jar，初步排查出来时因为websockets.jsr与websocket.server jar冲突，spring不知道需要用哪个实现，所以跑车
移除spring-boot-starter-undertow依赖即可
