java - spring boot websocket配置错误

Question

Caused by: java.lang.NoSuchMethodError: 'org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler 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);
}

}

这是所附的屏幕截图

Answer 1

在 activeMQ 的 pom.xml 文件中添加了额外的依赖项，因此 AbstractMessageBrokerConfiguration 类是从 active-mq-all.jar 中选取的，而不是应该从 simp/spring-messaging.jar 中选取的。

删除外部 Active mq 依赖关系解决了我的问题。
