我已经成功地从 here 运行了示例使用 SimpleBroker。
我的配置是这样设置的:
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
//registry.enableStompBrokerRelay("/queue/","/topic/").setRelayHost("localhost").setRelayPort(61614);
registry.setApplicationDestinationPrefixes("/app");
}
当我注释掉 SimpleBroker 并尝试使用 StompBroker 时,出现以下错误。

我是否缺少某些资源,因此它不会创建 bean stompBrokerRelayMessageHandler?
在 STS 内部的 Tomcat v7.0 上运行它,并使用 ActiveMQ 作为消息代理。
最佳答案
你需要在 pom.xml 添加这个
<!-- Reactor -->
