在MULE CE 3.3.0中，我有这个配置XML文件（我在下面复制了它）

之后我在浏览器中运行我的mule项目，我输入http://localhost:8089/services/Echo?wsdl然后我可以看到wsdl的代码。但有时，我的mule项目由于某种原因而停止，所以当我输入http://localhost:8089/services/Echo?wsdl时，我在浏览器中看到此消息could not connect to localhost:8089 或 page could not find。

我想控制此消息，实际上当我的服务（mule项目）关闭时，我发布了我设置它的自定义消息。例如，我在浏览器中向客户显示此消息：此时服务已关闭，请稍后再试!!!!

Answer 1

在生产环境中，可以通过在后端服务器关闭时放置一个知道该做什么的前端（即负载均衡器）来实现。

相反，当您尝试直接连接到后端（即您在工作室中运行的项目）并且此后端已关闭时，请由客户端（即您的浏览器）显示与404 http错误代码关联的错误消息。

您可以找到有关404 http状态如何工作的信息here
