java - Spring Boot Websocket配置错误

造成原因：java.lang.NoSuchMethodError：“ org.springframework.scheduling.concurrent.ThreadPoolTask​​Scheduler org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurationSupport.messageBrokerTaskScheduler（）”

@Configuration
@EnableWebSocketMessageBroker
 public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    registry.addEndpoint("/ws").setAllowedOrigins("https://localhost.com").withSockJS();
}

@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
    config.enableSimpleBroker("/aq-topic", "/aq-queue");
    config.setApplicationDestinationPrefixes("/aq-broker");
}

@Override
public void configureClientInboundChannel(ChannelRegistration channelRegistration) {
    channelRegistration.taskExecutor().corePoolSize(4).maxPoolSize(8);
}

@Override
public void configureClientOutboundChannel(ChannelRegistration channelRegistration) {
    channelRegistration.taskExecutor().corePoolSize(4).maxPoolSize(8);
}

}

这是附件的截图

最佳答案

在activeMQ的pom.xml文件中添加了附加的依赖项，因此从active-mq-all.jar中选择了AbstractMessageBrokerConfiguration类，而应该从simp / spring-messaging.jar中进行了选择。

删除外部Active mq依赖关系解决了我的问题。
