ESB 4.0.3 中的 WSO2 数据服务 (DS) 返回错误的故障消息

【问题标题】：WSO2 data service (DS) in ESB 4.0.3 returns wrong fault messageESB 4.0.3 中的 WSO2 数据服务 (DS) 返回错误的故障消息
【发布时间】：2017-02-13 07:49:17
【问题描述】：

我在 Apple 工作，我们正在使用带有数据服务功能的 WSO2 ESB 开发原型。我正在使用带有 DSS 功能的 WSO2 ESB 4.0.3。我已经部署了数据服务并从 ESB 中的代理服务调用数据服务。我使用的是MAC OS X 10.7.4，java 版本详情如下。

java版本“1.6.0_31” Java(TM) SE 运行时环境 (build 1.6.0_31-b04-415-11M3635) Java HotSpot(TM) 64 位服务器 VM（内部版本 20.6-b01-415，混合模式）

我的 DS 服务需要某个参数，比如参数 A，但我没有在输入 XML 中传递该参数，我在 WSO2 ESB 控制台上看到以下错误。

查看 SOAP 错误我必须将错误消息返回给客户端，但即使认为正确的错误消息必须“参数缺失”SOAP 错误的原因文本是“javax.xml.stream.XMLStreamException”

我做错了什么还是DSS中的BUG？

    【解决方案1】：

    通过查看堆栈跟踪，我可以看到您在调用服务时启用了 SOAP 跟踪器，禁用了 SOAP 跟踪器，您应该会收到正确的错误消息。

    干杯， 安佳娜。

    【讨论】：

      【解决方案2】：

      正如错误消息所解释的那样，它需要输入参数，而这些参数并未进入请求。它可以通过两种方式修复：

      1. 从 ESB 传递空标记而没有值。
      2. 在 DSS 中设置默认值。

      第一个选项适用于所有版本，这里是设置默认值的示例。 

      <payloadFactory media-type="xml">
    <format>
        <ds:DATA_SERVICE_REQUST xmlns:ds="http://ws.wso2.org/dataservice">
            <ds:INPUT_PARAM_1>$1</ds:INPUT_PARAM_1>
        </ds:DATA_SERVICE_REQUST>
    </format>
    <args>
        <arg xmlns:ds="http://ws.wso2.org/dataservice" evaluator="xml" expression="get-property('INPUT_PARAMETER')"/>
    </args>
</payloadFactory>
<call>
    <endpoint>
        <address uri="DSS_END_POINT"/>
   </endpoint>
</call>

      对于第二个选项，请检查您的 DSS 版本是否支持空值

      最新版本的 DSS 支持查询参数列表中的默认参数值。 您能否通过在数据服务 (dbs) 文件的查询参数列表中添加 defaultValue="#{NULL}" 来尝试一下？

      <query id="QUERY-ID" useConfig="DATA-SOURCE-ID">
    <sql>-------------SQL QUERY HERE -----</sql>
    <result ----------- >
        <element ------------ />  
    </result>
    <param defaultValue="#{NULL}" name="PARAM-NAME" ordinal="1" sqlType="INTEGER"/>
</query>

      如果此问题仍未解决，那么最好能提供您的 API 详细信息。
