SpringBoot引入WebSocket依赖报ServerContainer no avaliable

1、WebSocketConfig 文件报错

@Configuration
@EnableWebSocket
public class WebSocketConfig {

    @Bean
    public 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
