如何解决当在Quarkus中的无功消息传递中没有设置任何使用者时发生异常

我遵循了Quarkus官方消息传递指南，并创建了一个简单的示例来使用AMQP（Apache Artemis）来体验Reactive消息传递功能。

完整的代码是here。

该示例正在运行，但是存在一个小问题，我必须先启动curl来使用消息，然后再使用另一个curl发送消息。

// start consumer side.
curl http://localhost:8080/messages -H "Accept:text/event-stream"

// start sending.
curl http://localhost:8080/messages -d "Hello,Quarkus" -H "Content-Type:text/plain"

// then the consumer exit.
// and sending a message will cause an exception.

如果取消使用者，然后发送消息，则会引发异常。

即使没有连接使用者也可以在Apache Artemis中缓存消息。

解决方法

Apache ActiveMQ Artemis具有强大而灵活的addressing model。如果您的方案是点对点消息传递，则可以定义地址以定制代理配置，即：

<address name="messages">
    <anycast>
        <queue name="messages" />
    </anycast>
</address>

代理将在启动时创建配置中定义的所有地址和队列，因此，发件人发送消息时，它将被路由到现有队列。
