Question

我已经read自从2.2.0版开始，Spring Boot就支持Kotlin Coroutines。但是，当我使用spring amqp（版本2.2.0）尝试这样做时：

@RabbitListener(...)
@Component
class EventConsumer {

    @RabbitHandler
    suspend fun consumeEvent(e: MyEvent) {
        ...
    }
}

然后发布一个事件：

rabbitTemplate.convertAndSend("my-exchange", "my-routing-key", MyEvent("data"))

我收到以下错误：

org.springframework.amqp.rabbit.support.ListenerExecutionFailedException: Listener method could not be invoked with the incoming message

如果我删除了suspend关键字，那么一切都会按预期进行。

我需要对Spring AMQP进行一些特殊配置才能与Kotlin Coroutines一起使用吗？

如何使用Kotlin协程在Spring AMQP中使用消息？
