Question

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 WSO2 ESB 4.0.3 和 DSS 功能。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 MAC OS X 10.7.4 ，java版本的详细信息如下。

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

我的DS服务期望某个参数说参数A而我没有在输入XML中传递这个参数我在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是甚至认为正确的错误消息必须是“参数丢失”SOAP错误的原因文本是“javax.xml.stream.XMLStreamException”

我在做什么事情或DSS中是否有错误？

Answer 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，您应该得到正确的错误消息。

干杯，长香。

Answer 2

当错误消息解释自己时，它期望输入参数，它不会出现在请求中。它可以通过两种方式修复：

从ESB传递空标记而没有值。
在DSS中设置默认值。

第一个选项适用于所有版本，以下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。您能否尝试在数据服务（dbs）文件的查询参数列表中添加defaultValue="#{NULL}"？

<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，那么您可以提供API详细信息。
