我最近设置了一个 SpringSource CloudFoundry 微云实例，并尝试使用此处找到的 RabbitMQ（带有代码）运行他们相当简短的消息传递示例：

http://support.cloudfoundry.com/entries/20322602-getting-started-with-the-rabbitmq-service-from-a-spring-application

此处提供了该应用程序的公共工作实例：

http://rabbit-simple.cloudfoundry.com

当我尝试这样做时，环境设置正确，代码构建、部署（使用 vmc 命令行工具）并毫无问题地绑定到 rabbitmq 服务。这是运行“vmc 应用程序”的控制台输出：

Macintosh-2:target wlaprise$ vmc push rabbit-simple

当我尝试从浏览器运行该应用程序时，它最初会正确显示输入表单，但是当我输入一条消息并点击“发布”时，我会返回此 500 错误：

Exception--------

    org.springframework.amqp.rabbit.core.RabbitTemplate.convertAndSend(RabbitTemplate.java:175)
    com.c3works.msg.HomeController.publish(HomeController.java:25)

有没有人成功地完成了这项工作并且知道我可能做错了什么（RabbitMQ 问题、CloudFoundry 问题、我自己的问题 :0 ）？

我所做的唯一与 SpringSource 的教程代码不同的事情是将 HomeController 中的返回字符串从：return "WEB-INF/views/home.jsp"; 到“home”以与在 spring-context.xml 文件中设置 viewResolver 的方式一致（这甚至是让输入表单正确显示所必需的）。

谢谢。

我在没有使用 STS 编辑器的情况下从头开始重新构建它并且它运行正常。我无法真正解释为什么从 STS IDE 中的 Maven 项目构建它会导致我遇到的问题，但是只使用文本编辑器和 vmc 命令行指令对所有内容进行干净构建是有效的。
