我正在开发一个spring mvc项目。有时在启动SpringBoot应用程序时，我遇到了错误。

org.springframework.context.ApplicationContextException：无法启动嵌入式容器;嵌套异常是 java.lang.ClassCastException：

详细日志如下：

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is java.lang.ClassCastException: org.apache.tomcat.websocket.WsWebSocketContainer cannot be cast to io.undertow.websockets.jsr.ServerWebSocketContainer

在你的pom.xml中删除它:)

   <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-undertow</artifactId>
    </dependency>

org.apache.tomcat.websocket.WsWebSocketContainer无法强制转换为io.undertow.websockets.jsr.ServerWebSocketContainer
