Question

我尝试按如下方式发送消息：

rabbitTemplate.convertAndSend("my.exchange", "my.queue", "Test Message");

并尝试接收如下消息：

@RabbitListener(bindings = @QueueBinding(value = @Queue(value = "my.queue", durable = "true"), exchange = @Exchange(value = "my.exchange", durable = "true", type = ExchangeTypes.TOPIC)))
public void receiveAuditMessage(String message) {
    log.info("Received <" + message + ">");     
}

没用。

但是如果我在@SpringBootApplication中指定了Queue，TopicExchange，Binding，那么它的工作正常。

@Bean
Queue queue() {
    return new Queue("my.queue");
}

@Bean
TopicExchange exchange() {
    return new TopicExchange("my.exchange");
}

@Bean
Binding binding(Queue queue, TopicExchange exchange) {
    return BindingBuilder.bind(queue).to(exchange).with("my.queue");
}

是否必须在SpringBootApplication中指定Queue，TopicExchange，Binding？如果是，那么如何在SpringBootApplication中指定多个Queue，TopicExchange，Binding？

请在这里帮助我。感谢。

在第一种情况下，您正在创建队列和交换，但没有绑定的路由键;你需要一个TOPIC交换的路由密钥......

if (!preg_match('/[^A-Za-z0-9]+/', $string)) {
    // $string contains only English letters and digits
}

或@RabbitListener(bindings = @QueueBinding(value = @Queue(value = "my.queue", durable = "true"), exchange = @Exchange(value = "my.exchange", durable = "true", type = ExchangeTypes.TOPIC), key = "my.queue")) public void receiveAuditMessage(String message) { System.out.println("Received <" + message + ">"); }获取所有讯息。

如果我没有在SpringBootApplication
