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

原因：java.lang.RuntimeException: java.lang.ClassCastException: org.apache.tomcat.websocket.server.WsServerContainer 无法在 io.undertow.servlet.core.DeploymentManagerImpl 强制转换为 io.undertow.websockets.jsr.ServerWebSocketContainer。在 org.wildfly.extension.undertow.deployment.UndertowDeploymentService.startContext(UndertowDeploymentService.java:87) 在 org.wildfly.extension.undertow.deployment.UndertowDeploymentService.start(UndertowDeploymentService.java:72) 部署（DeploymentManagerImpl.java:219）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 $StartTask.run(ServiceControllerImpl.java:1881) [jboss-msc-1.2.2.Final.jar:1.2.2.Final] ... 3 更多原因：java.lang。ClassCastException：org.apache.tomcat.websocket.server.WsServerContainer 无法在 io.undertow.websockets.jsr.Bootstrap$WebSocketListener.contextInitialized(Bootstrap.java:69) 处转换​​为 io.undertow.websockets.jsr.ServerWebSocketContainer。 undertow.servlet.core.ApplicationListeners.contextInitialized(ApplicationListeners.java:173) at io.undertow.servlet.core.DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:190) ... 还有 7 个DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:190) ... 还有 7 个DeploymentManagerImpl.deploy(DeploymentManagerImpl.java:190) ... 还有 7 个

看来我的 websockets 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并且提议的解决方案似乎都不适合我。以下是我的 pom 中的依赖项：

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

        <artifactId>postgresql</artifactId>
        <version>9.1-901.jdbc4</version>
    </dependency>
</dependencies>

我也尝试使用直接的 spring-boot-starter-websocket，但得到了同样的结果。这也是我的 websocket 配置：

@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");
}
}

感谢您抽时间阅读。我将不胜感激任何帮助。此外，这是我的第一个启动应用程序。：/

您需要排除 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>

spring-boot-starter-web 和 spring-boot-starter-websocket 默认包含 spring-boot-starter-tomcat 所以排除 tomcat，如下所示

     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>${spring-boot.version}</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-websocket</artifactId>
        <version>${spring-boot.version}</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-tomcat</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

并包括undertow，确保tomcat在类路径中不存在。

我不确定，但是您围绕 websockets 的 POM 应该是这样的：

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

<dependency>
    <groupId>org.apache.tomcat.embed</groupId>
    <artifactId>tomcat-embed-websocket</artifactId>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>

spring-messaging, spring-websocket, jackson-databind,spring-boot-starter-web是多余的。

还有spring-boot-starter-thymeleaf.

但是，我认为您的原因的根源是tomcat-embed-websocket.

使用以下命令查找所有依赖项，其中包括spring-boot-starter-tomcat：

mvn dependency:tree -Dincludes=org.springframework.boot:spring-boot-starter-tomcat

从此命令列出的所有依赖项中排除 Tomcat 启动程序。

之后，您可能需要添加javax.servlet-api作为提供的依赖项：

<dependency>
    <artifactId>javax.servlet</artifactId>
    <groupId>javax.servlet-api</groupId>
    <scope>provided</scope>
</dependency>

好吧，上面给出的解决方案都不适合我。

实际上是父版本中的版本造成了问题。

不工作：

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.3.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

在职的：

     <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.0</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

对我来说，spring-boot-starter-websocket 和 spring-boot-starter-web 默认包含 spring-boot-starter-tomcat 所以排除 tomcat，如下图没有 spring boot 版本：

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