Question

它应该很简单，但我无法设置它。我的XML看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:ws="http://www.mulesoft.org/schema/mule/ws" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:data-mapper="http://www.mulesoft.org/schema/mule/ee/data-mapper" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

    <ws:consumer-config name="Web_Service_Consumer" wsdlLocation="http://procese/sysworkflow/en/classic/services/wsdl2" service="ProcessMakerService" port="ProcessMakerServiceSoap" serviceAddress="http://procese:80/sysworkflow/en/classic/services/soap2" doc:name="Web Service Consumer"/>
    <data-mapper:config name="JSON_To_XML" transformationGraphPath="json_to_xml.grf" doc:name="JSON_To_XML"/>
    <flow name="ws_pm_login3Flow">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/>
        <set-payload value="#[{&quot;userid&quot;:&quot;xyz.qwe&quot;, &quot;password&quot;:&quot;12345&quot;}]" doc:name="Set Payload"/>
        <data-mapper:transform config-ref="JSON_To_XML" doc:name="JSON To XML"/>
        <ws:consumer config-ref="Web_Service_Consumer" operation="login" doc:name="Web Service Consumer"/>
    </flow>
</mule>

WS工作正常。

映射器文件json_to_xml.grf如下所示：

当我开始这个过程时，我得到了：

Error executing graph: ERROR (com.mulesoft.mule.module.datamapper.api.exception.DataMapperExecutionException). Message payload is of type: HashMap

我正在使用3.6.1 EE

我错过了什么？

原来在骡子中使用JSON中的双引号是一个问题。我转向XML，现在它工作正常。

如何使用mule setvariable和datamapper从WSDL获取变量？消息有效内容的类型为：HashMap
