JAXB 转换在 Mule 中不起作用

Question

我正在按照 Mule 教程执行 JAXB 转换。下面是我得到的异常跟踪，然后是我的配置

我在 JDK 1.7

上使用 Mule 3.6.2 EE

我的 XML 配置如下所示

<http:request-config name="United_REST_Request_Configuration" host="localhost" port="8112" basePath="essentials/united/flights" doc:name="HTTP Request Configuration"/>
<http:request-config name="Bank_REST_Request_Configuration" host="training.cloudhub.io" port="80" basePath="/build/banking/rest" doc:name="HTTP Request Configuration">
    <http:raml-api-configuration location="http://localhost:8112/build/banking/raml"/>
</http:request-config>

<mulexml:jaxb-context name="JAXB_Context" packageNames="com.mulesoft.training" doc:name="JAXB Context" />

<flow name="getDeltaFlightsFlow">
    <http:listener config-ref="HTTP_Listener_Configuration" path="/delta" allowedMethods="GET" doc:name="/delta"/>
    <ws:consumer config-ref="Delta_Web_Service_Consumer" operation="listAllFlights" doc:name="listAllFlightsWS"/>
    <mulexml:jaxb-xml-to-object-transformer returnClass="com.mulesoft.training.FlightArray" jaxbContext-ref="JAXB_Context" doc:name="XML to JAXB Object"/>
    <logger message="#[payload]" level="INFO" doc:name="Logger"/>
</flow>

我的包结构如下所示

Answer 1

eclipse (mule studio) 中的 Mule 项目是 Java 项目类型的扩展。 Java 项目中的所有资源都必须进入资源类型 class 路径条目，简而言之，src/main/resources 是这些类型的文件必须存在的位置。您可以在那里创建一个包并放置资源，它应该可以工作。

对于 mule 项目从中获取结构的 Maven 也是如此。

JAXB 转换在 Mule 中不起作用
