Error creating bean with name 'webSocketServer'(springboot 整合webstock )

   今天踩了一個坑記錄下，springboot項目，整合webstock,總是報以下錯誤

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webSocketServer': Lookup method resolution failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class 
...
Caused by: java.lang.IllegalStateException: Failed to introspect Class [com.safesys.monitoring.util.WebSocketServer] from ClassLoader [org.springframework.boot.devtools.restart.classloader.RestartClassLoader@2f6f3352]
...
at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.determineCandidateConstructors(AutowiredAnnotationBeanPostProcessor.java:248)
...
Caused by: java.lang.ClassNotFoundException: javax.websocket.Session
...
Disconnected from the target VM, address: '127.0.0.1:50767', transport: 'socket'

剛剛開始，各種找錯，發現只要添加 ServerEndpointExporter 就報錯了

@Bean
public ServerEndpointExporter serverEndpointExporter() {
    return new ServerEndpointExporter();
}

也找過很多帖子，讓你注釋啟動test類的@RunWith(SpringRunner.class) 或者修改@SpringBootTest為測試環境之類的

反正各種找，准備放棄的時候，我嘗試看看tomcate自身問題，因為要打war，之前pom做過修改

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <!--聲明spring boot內嵌tomcat的作用范圍  在運行時不起作用-->
    <scope>provided</scope>
</dependency>

看了注釋，我注釋了<scope>provided</scope> ，然后刷新包，發現真可以啟動了，暫時先記錄下，這個還是容器依賴的問題，要讓springboot內置tomcate和web生效才行，沒時間，就到這把，記錄下
