我是一名经验丰富的 Java 程序员，并且是第一次尝试 Spring Rabbit MQ。
我遵循了 messages-rabbitMQ 教程exactly使用 Maven。http://spring.io/guides/gs/messaging-rabbitmq/ http://spring.io/guides/gs/messaging-rabbitmq/
我在 CentOS 上作为用户帐户运行。
当我在教程最后运行应用程序时java -jar target/gs-messaging-rabbitmq-0.1.0.jar，我收到以下连接被拒绝错误。有人可以帮忙吗？
prompt> java -jar target/gs-messaging-rabbitmq-0.1.0.jar

您没有安装 RabbitMQ 服务器。幸运的是，这很容易做到。你提到你使用的是CentOS，在这里你可以下载RabbitMQ服务器：https://www.rabbitmq.com/install-rpm.html https://www.rabbitmq.com/install-rpm.html
您需要执行几个步骤，包括安装 Erlang。
Spring 示例假设您已经了解一些有关使用消息代理的信息。这本身就是您需要使用的一项技术，就像您必须学习使用数据库或操作系统一样。
