使用 WSO2 DSS 记录未追踪到数据库中

Question

我正在 WSO2 EI 6.1.1 中执行 DSS 操作。在管理控制台中检查 DSS 操作时，记录被追踪到数据库中，但是当我尝试通过编码执行相同的操作时，记录没有被追踪到数据库中，但是如果我在端点调用之后进行响应，则会获得成功作为响应。谁能告诉我这里出了什么问题？

数据服务(XML):

<data name="CarSalesDSS" transports="http https local">
   <config enableOData="false" id="CarSales_DataSource">
      <property name="driverClassName">com.mysql.jdbc.Driver</property>
      <property name="url">url</property>
      <property name="username">username</property>
      <property name="password">password</property>
      <property name="autoCommit">true</property>
      <property name="dataSourceProps"/>
      <property name="dynamicUserAuthMapping">
         <configuration/>
      </property>
   </config>
   
   <query id="Staging_Leads_Query" useConfig="CarSales_DataSource">
      <sql>insert into :Staging_LeadsTable(LeadID,Type,Salutation,FirstName,LastName,Email,MobilePhone) &#xd;values (:LeadID,:Type,:Salutation,:FirstName,:LastName,:Email,:MobilePhone)&#xd; ON DUPLICATE KEY UPDATE Type =:Type,Salutation =:Salutation,FirstName =:FirstName,LastName =:LastName,Email =:Email,MobilePhone =:MobilePhone</sql>
      <param name="Staging_LeadsTable" sqlType="QUERY_STRING"/>
      <param name="LeadID" sqlType="STRING"/>
      <param name="Salutation" sqlType="STRING"/>
      <param name="Type" sqlType="STRING"/>
      <param name="FirstName" sqlType="STRING"/>
      <param name="LastName" sqlType="STRING"/>
      <param name="Email" sqlType="STRING"/>
      <param name="MobilePhone" sqlType="STRING"/>
   </query>
   
   <operation name="Staging_Leads_Opr" returnRequestStatus="true">
      <call-query href="Staging_Leads_Query">
         <with-param name="Staging_LeadsTable" query-param="Staging_LeadsTable"/>
         <with-param name="LeadID" query-param="LeadID"/>
         <with-param name="Salutation" query-param="Salutation"/>
         <with-param name="Type" query-param="Type"/>
         <with-param name="FirstName" query-param="FirstName"/>
         <with-param name="LastName" query-param="LastName"/>
         <with-param name="Email" query-param="Email"/>
         <with-param name="MobilePhone" query-param="MobilePhone"/>
      </call-query>
   </operation>
</data>

管理控制台（TryIt 工具）：

Answer 1

你能试试在调用调解器之前添加 action header 吗？

 <header name="Action" value="urn:Staging_Leads_Opr" scope="default"/>

Answer 2

我通过在 payload Factory 的 arg 参数中提供输入值解决了上述问题Mediator.but仍然不知道为什么直接映射不起作用。

    <payloadFactory media-type="xml">
                            <format>
                                <soapenv:Envelope xmlns:dat="http://ws.wso2.org/dataservice" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
                                    <soapenv:Header/>
                                    <soapenv:Body>
                                        <p:Staging_Leads_Opr xmlns:p="http://ws.wso2.org/dataservice">
                                            <!--Exactly 1 occurrence-->

                                            <!--Exactly 1 occurrence-->
                                            <xs:LeadID xmlns:xs="http://ws.wso2.org/dataservice"></xs:LeadID>
                                            <!--Exactly 1 occurrence-->
                                            <xs:Salutation xmlns:xs="http://ws.wso2.org/dataservice"></xs:Salutation>
                                        </p:Staging_Leads_Opr>

                            <args>
                                <arg evaluator="xml" expression="get-property('Staging_LeadsTable')"/>

                            </args>
                        </payloadFactory>
                        <call description="CarSalesDSS">
