运行 mule 应用程序时出错

Question

我是 Mule 的新手，正在尝试关注 http://www.mulesoft.org/documentation/display/current/JDBC+Transport+Reference#JDBCTransportReference-LargeDataset

这是我的 mule 配置文件

        <vm:inbound-endpoint exchange-pattern="one-way" path="vm://next.batch"/>
        <spring-object bean="noArgsWrapper" /> 
 </flow>

</mule>

但是，在运行 mule 应用程序时，我收到以下错误：

Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'vm:inbound-endpoint'. One of '{"http://www.mulesoft.org/schema/mule/core":abstract-message-processor, "http://www.mulesoft.org/schema/mule/core":abstract-outbound-endpoint, "http://www.mulesoft.org/schema/mule/core":abstract-mixed-content-message-processor, "http://www.mulesoft.org/schema/mule/core":response}' is expected.

我试图在谷歌上搜索它，但没有得到任何可行的解决方案。 仅供参考 - 我的班级路径中有 mule-transport-vm-3.4.1.jar（在某处给出的解决此问题的建议之一）

Answer 1

您不能直接在流程中使用spring-object，而是可以使用Java组件并引用spring object，如下所示。

<component doc:name="Java">
        <spring-object bean="noArgsWrapper"/>
    </component>

Answer 2

同一流中不能有两个入站端点。你想达到什么目的？短期内，移除 vm:inbound-endpoint。

您可能想在 spring-object 之后使其成为 outbound-endpoint？

Answer 3

您在这里有一个有效且详细的示例：

Answer 4

如果您有多个入站端点，请在复合范围内定义它们。
