Spring RabbitMQ教程导致Connection Refused错误

时间：2015-05-13 19:01:05

标签： java spring rabbitmq spring-amqp

我是一位经验丰富的Java程序员，我第一次尝试使用Spring Rabbit MQ。

我使用Maven跟踪了messaging-rabbitMQ教程完全。 http://spring.io/guides/gs/messaging-rabbitmq/

我作为用户帐户在CentOS上运行。

当我在教程的最后用java -jar target/gs-messaging-rabbitmq-0.1.0.jar运行应用程序时，我收到以下连接拒绝错误。有人可以帮忙吗？

prompt> java -jar target/gs-messaging-rabbitmq-0.1.0.jar

答案 0 :(得分：8)

您没有安装RabbitMQ服务器。幸运的是，这很容易做到。您提到您使用的是CentOS，在这里您可以下载RabbitMQ服务器：https://www.rabbitmq.com/install-rpm.html

您需要遵循几个步骤，包括安装Erlang。

Spring示例假设您已经了解了使用消息代理的一些信息。这本身就是您需要使用的技术，例如您必须学习使用数据库或操作系统时。

这是一个老问题，但无论如何我都会发布我的答案，因为它解决了Spring教程中这一特定步骤的问题，而其他答案却没有。

如果您使用Spring教程中指定的docker-compose.yml文件在Docker容器中启动RabbitMQ服务器，您可能会遇到我连接到它的相同问题，我在这个问题中概述了这个问题;

Docker image for Spring/RabbitMQ tutorial results in connection refused

几天后回到它之后虽然我找到了解决方案;

遗憾的是，Spring教程没有说明在选择使用docker-compose文件而不是手动安装RabbitMQ时需要配置连接信息，这很不幸，因为Docker方法看起来更简单，更直接。
