未使用 WSO2 DSS 跟踪到 DB 的记录答案

【问题标题】：Record not traced into DB using WSO2 DSS未使用 WSO2 DSS 跟踪到 DB 的记录
【发布时间】：2020-11-25 13:21:47
【问题描述】：

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，记录被跟踪到数据库中，但是当我尝试通过编码执行相同的操作时，记录不会被跟踪到数据库中，但是如果我在端点调用之后得到成功作为响应。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>

【解决方案1】：

您可以尝试在呼叫中介之前添加操作标头吗？

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

嗨@Shanaka Premarathna，感谢您的回复，尝试了同样的方法，但此操作标题对我没有帮助。

【解决方案2】：

我通过在有效负载工厂调解器的 arg 参数中提供输入值解决了上述问题。但仍然不知道为什么直接映射不起作用。

    <payloadFactory media-type="xml">
