我将数据映射器（将xml转换为POJO）迁移到数据编织。但是在执行流程时，我看到了以下异常
“值选择器”运算符的类型不匹配 发现：string，：name required：datetime，：name或 required：localdatetime，：name或 required：object，：name或 要求：时间，：名称或 required：array，：name或 要求：日期，：名称或 必需：localtime，：name或 required：period，：name。
输入（Payload）是如下的XML：

和dw变换看起来像
%dw 1.0
%output application/java

{
brwrFirstName: payload.RESPONSE_GROUP.RESPONSE.RESPONSE_DATA.FLOOD_RESPONSE.BORROWER.@"_FirstName",
brwrLastName: payload.RESPONSE_GROUP.RESPONSE.RESPONSE_DATA.FLOOD_RESPONSE.BORROWER.@"_LastName" default '',
我在brwrFirstName看到错误：payload.RESPONSE_GROUP.RESPONSE.RESPONSE_DATA.FLOOD_RESPONSE
答案 0 :(得分：4)
正如Chad所说，你应该发布你的输入和实际的mule XML（不仅仅是DW代码），这将有助于人们更好地理解它。
根据提供的信息，看起来有效载荷是一个字符串，DW说它不能应用“。”字符串上的选择器。这就是你得到的错误。选择器只能应用于错误中所述的类型。
现在您希望DW将您的字符串解释为XML并进行相应的解析。有时，DW不知道这样做。但是，您可以在有效内容上强制使用DW类型将字符串解释为XML。只需将下面的子元素与适当的mimeType一起添加到<dw:transform-message>元素。
<dw:input-payload mimeType="application/xml"/>
这将强制DW将字符串解析为XML，并且您的应用程序应该在那时工作。您也可以将mimeType属性应用于<dw:input-variable>。
mule xml文件中的完整DW示例：
<dw:transform-message doc:name="Transform Message">
<dw:input-payload mimeType="application/xml"/>
<dw:set-payload>

}]]>
</dw:set-payload>
</dw:transform-message>

面临错误：
ERROR 2017-03-07 12:49:50,060 [[bulk_create_poc].HTTP_Listener_Configuration.worker.01] org.mule.exception.DefaultMessagingExceptionStrategy:
Message : Exception while executing:

为解决方案添加以下代码段
<dw:input-payload mimeType="application/xml"/>
在此处
<dw:transform-message doc:name="Transform Message" metadata:id="b12f4d65-2bb0-43e9-b775-c2077863ba48">

添加mime类型的数据类型对我来说真的很有用
我遇到的错误：

****Resolution that worked for me :****
