我正在使用带有 WSO2 ESB 4.6.0 和数据服务功能的 MAC OS X - 10.7.5 - 4.0.5

Java java 版本“1.6.0_37” Java(TM) SE 运行时环境（内部版本 1.6.0_37-b06-434-11M3909） Java HotSpot(TM) 64 位服务器 VM（内部版本 20.12-b01-434，混合模式）

我正在尝试使用 ref 游标执行存储过程。

这是我的DS

<data name="RZM">
   <config id="RZS_Data">
      <property name="driverClassName">oracle.jdbc.driver.OracleDriver</property>
      <property name="url">XXXX</property>

      <property name="defaultTransactionIsolation">TRANSACTION_READ_COMMITTED</property>
   </config>
   <query id="TEST" useConfig="RZS_Data">
      <sql>call RT_PROC_GET_VERSION(:in_app_id,:in_version_id,?,?,?)</sql>
      <result element="Results" rowName="Result">

   </query>
   <operation name="TOP">

         <with-param name="in_version_id" query-param="in_version_id"/>
      </call-query>
   </operation>
</data>

我一直收到以下错误

我不确定为什么会收到此错误。我正在尝试使用“TryIt”服务执行 DS。输入 XML 如下

<body>
   <p:TOP xmlns:p="http://ws.wso2.org/dataservice">
      <!--Exactly 1 occurrence-->
      <p:in_app_id>1296</p:in_app_id>
      <!--Exactly 1 occurrence-->
      <p:in_version_id>2.2</p:in_version_id>
   </p:TOP>
</body>

存储过程定义从以下开始

     create or replace procedure RT_PROC_GET_VERSION (in_app_id                in number,
                                                    in_version_id           in varchar2,
                                                    out_version_detail      out sys_refcursor,
                                                    out_message             out varchar2,
                                                    out_err_message         out varchar2)
    is
    begin
            open out_version_detail for
            select
                    app_url, switch_board_url, version
.
.

end RT_PROC_GET_VERSION;

你能帮忙吗？谢谢阿比吉特

我也一直在与它作斗争，我花了一些时间调试代码，并认为原因是 MessageContext 中的请求为“空”。所以它导致了 Axis2 传输配置影响了它的事实。事实上，WSO2 ESB 4.6.0 带有默认的直通 http 传输，它不会创建消息正文，这就是为什么您传递给服务的任何内容都不起作用的原因。因此，为了使其工作，您需要重新启用替代 http 传输（例如 find 和 uncomment org.wso2.carbon.core.transports.http.HttpTransportListener），repository/conf/axis2/axis2.xml 这应该以禁用路径为代价来解决您的问题。也许有办法在不同的端口上并排配置传输（稍后的任务）

需要注意的是，通常您应该将 ESB 和 DSS 分开保存，因为解决不同的任务并需要特定的配置。

试试这个调用 RT_PROC_GET_VERSION(?,?,?,?,?)

并在输入映射选项中列出所有带有序数的 in 和 out 参数。序数将基于问号。一件事是上述查询中出现的问号应该与您的存储过程相同。在此之后，如果有任何数据来自存储过程，则将它们列在 out 参数中

例如：如果您的结果集带有 id 和 address，则在输出映射中列出这两个。注意：输入映射名称应与存储过程中的名称相同。

阿比吉特，

同时使用“命名参数”和“序数”（参数以数字排序）会导致参数提取和分配中的一些问题。我建议您统一使用“命名参数”选项或“序数”（两者中只有一个）来分配所有输入参数映射。那将解决问题。

希望这可以帮助！
