使用Mule Server 3.8.1中的选择流程（Anypoint Studio 6.2.1）

时间：2017-01-14 23:43:56

标签： mule mule-component

我是Mule的新手，并试图了解产品如何运作的细微差别。作为我尝试的几个实验的一部分，我碰巧尝试了选择流程。但我无法上班。当我尝试在我的Mule流程中使用它时，总是会出现XML错误。当我从调色板中拖动选项时，编辑器也不允许我添加流元素。我总是需要处理XML以使其显示在消息流编辑器中。这可能是一件简单的事情，但我发现很难弄清楚这里有什么问题。我正在尝试的样本如下。它只是根据http请求中发布的语言打印问候语。但它不起作用。

我收到以下错误

此外，还有从将调色板中的choice元素添加到消息流的情况。它不允许我在when构造下添加任何东西来定义Route消息。我必须始终将xml粘贴到配置XML中，以便在消息流中显示流enter image description here

非常感谢任何帮助。

答案 0 :(得分：0)

问题：在当行中键入要使用的条件很棘手。

解决方案： 请完全按照this example中的说明进行操作。这一系列步骤根本不直观。

  1. 在Studio中，在属性编辑器中单击下面的“何时”。出现一个对话框。输入并保存第一个条件。第一个条件出现在When。
    2. 下的属性编辑器中
  2. 在属性编辑器中，在第一个条件下方单击下一个“时”行以再次显示该对话框。输入并保存第二个条件。

    3. 陷阱：不要使用软返回在对话框中键入多个条件。此外，请勿单击此示例的对话框中的“否则”选项。按照上面文档链接中的说明进入其他代码。

    Re：将Set Payload或其他组件从调色板拖到画布连接到Choice的问题，诀窍是在看到指示符时删除其他组件。在连接到Choice的情况下，会立即显示黑色垂直线，如下所示：enter image description here
