我正试图使用

Spring 4

向安装在我的

localhost

上的

RabbitMQ

发送消息，但由于某种原因，消息没有被发送，我也没有收到任何错误。在我看来，我的Spring配置（

beans.xml

）不正确

请导游

pom.xml

您需要告诉RabbitMQ如何路由消息

由于您没有创建exchange或将队列绑定到exchange，因此可以使用队列名称路由到默认exchange（

“”

）

您需要将模板上的

routingKey

属性（

routing key

属性）设置为队列名称，或者需要将其包含在

convertAndSend

调用中：

template.convertAndSend("", "helloQueue", helloWorld.getMessage());

RabbitMQ只是删除成功传递到exchange但未路由到任何队列的消息

请参阅以了解交换、路由密钥等

有Spring引导版本的教程。
