Wildfly中的Spring Boot Websockets [英] Spring Boot Websockets in Wildfly

问题描述

我需要将Spring Boot应用程序部署到Wildfly 8.1中，并且出现以下异常:

Hi I need to deploy my Spring Boot app into Wildfly 8.1 and I'm getting the following exception:

原因:java.lang.RuntimeException:java.lang.ClassCastException:org.apache.tomcat.websocket.server.WsServerContainer无法转换为io.undertow.websockets.jsr.ServerWebSocketContainer 在io.undertow.servlet.core.DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:219) 在org.wildfly.extension.undertow.deployment.UndertowDeploymentService.startContext(UndertowDeploymentService.java:87) 在org.wildfly.extension.undertow.deployment.UndertowDeploymentService.start(UndertowDeploymentService.java:72) 在org.jboss.msc.service.ServiceControllerImpl $ StartTask.startService(ServiceControllerImpl.java:1948)[jboss-msc-1.2.2.Final.jar:1.2.2.Final] 在org.jboss.msc.service.ServiceControllerImpl $ StartTask.run(ServiceControllerImpl.java:1881)[jboss-msc-1.2.2.Final.jar:1.2.2.Final] ...另外3个 由以下原因引起:java.lang.ClassCastException:org.apache.tomcat.websocket.server.WsServerContainer无法转换为io.undertow.websockets.jsr.ServerWebSocketContainer 在io.undertow.websockets.jsr.Bootstrap $ WebSocketListener.contextInitialized(Bootstrap.java:69) 在io.undertow.servlet.core.ApplicationListeners.contextInitialized(ApplicationListeners.java:173) 在io.undertow.servlet.core.DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:190) ...还有7个

似乎我的网络套接字和消息传递设置可能是罪魁祸首? 我在看这个 https://github.com/joshlong/boot-examples/issues/2 所提出的解决方案似乎都不适合我.这是我pom的依赖项:

It seems that my setup for websockets and messaging might be the culprit? I was looking at this https://github.com/joshlong/boot-examples/issues/2 And none of the proposed solutions seem to work for me. Here are the dependencies from my pom:

    <groupId>org.springframework.boot</groupId>

我也尝试使用直接spring-boot-starter-websocket，但是得到了同样的东西. 这也是我的websocket配置:

I tried using the direct spring-boot-starter-websocket as well but get the same thing. Here is my websocket config too:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer{

@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
    super.configureMessageBroker(registry);
    registry.enableSimpleBroker("/ssp");
    registry.setApplicationDestinationPrefixes("/inc");
}

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/update/applications");
}
}

感谢您抽出宝贵的时间阅读本文档.任何帮助我将不胜感激. 另外，这是我的第一个启动应用程序. :/

Thanks for taking the time to read this. Any help would me most appreciated. Also, this is my first boot application. :/

推荐答案

您需要排除tomcat-embed-websocket

You need exclude tomcat-embed-websocket

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.apache.tomcat.embed</groupId>
                <artifactId>tomcat-embed-websocket</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
