在wso2esb中使用迭代器介體時出錯

[英]Error while using iterator mediator in wso2esb

 原文  2014-09-23 07:22:20  8   1    loops/ wso2/ wso2esb/ wso2dss

問題描述

我正在使用wso2esb 4.7.0和wso2dss 3.1.0。我的場景是我希望選擇關於特定clientid的所有partybranch。 為此，我有一個類似的查詢： 

select partybranchid,clientid from mpartybranch where clientid = 473906852857651

它給了我2條記錄的清單，例如： 

partybranchid    clientid

-2500000000      473906852857651
796243010946586  473906852857651

我希望將這兩個分開並找出每個地址。​​我在dss中使用以下查詢，對我來說單獨工作是： 

select * from address where partybranchid = ? and clientid =?

現在我在wso2esb中使用了迭代器中介器，只需單擊即可實現此功能。我的配置是： 

     <iterate xmlns:f="http://ws.wso2.org/dataservice" continueParent="true" preservePayload="true" expression="//f:Datalist" id="iterate1" sequential="true">
        <target>
           <sequence>
              <property xmlns:s="http://ws.wso2.org/dataservice" name="partybranchid1" expression="//s:partybranchid/text()" scope="default" type="STRING"/>
              <property xmlns:s="http://ws.wso2.org/dataservice" name="latitude" expression="get-property('latitude')"/>
              <property xmlns:s="http://ws.wso2.org/dataservice" name="longitude" expression="get-property('longitude')"/>
              <property xmlns:s="http://ws.wso2.org/dataservice" name="radius" expression="get-property('radius')"/>
              <payloadFactory media-type="xml">
                 <format>
                    <p:select_addresses_op xmlns:p="http://ws.wso2.org/dataservice">
                       <p:latitude>$1</p:latitude>
                       <p:longitude>$2</p:longitude>
                       <p:radius>$3</p:radius>
                       <p:objectid>$4</p:objectid>
                    </p:select_addresses_op>
                 </format>
                 <args>
                    <arg xmlns:s="http://ws.wso2.org/dataservice" expression="get-property('latitude')" evaluator="xml"/>
                    <arg xmlns:s="http://ws.wso2.org/dataservice" expression="get-property('longitude')" evaluator="xml"/>
                    <arg xmlns:s="http://ws.wso2.org/dataservice" expression="get-property('radius')" evaluator="xml"/>
                    <arg xmlns:s="http://ws.wso2.org/dataservice" expression="get-property('partybranchid1')" evaluator="xml"/>
                 </args>
              </payloadFactory>
              <property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/>
              <property name="messageType" value="application/json" scope="axis2"/>
              <send receive="spatial_seq3">
                 <endpoint>
                    <address uri="http://localhost:9764/services/Aspatialtrial_Dataservice/" format="soap11"/>
                 </endpoint>
              </send>
           </sequence>
        </target>
     </iterate>

此配置有效，但未提供預期的輸出。以下是客戶端和服務器端的輸出：

在服務器端（ESB）輸出：

在客戶端輸出

要求是： 

 curl -v -H "Accept: application/json" -H "Content-Type:application/json" -H "ModifiedOn:0"   -H "username:vikash|214057357158656" -H "password:gbadmin" -d '{"usercode":"suresh","clientid":"473906852857651","longitude":"72.8258","radius":"10","latitude":"18.975"}' http://youtility-desktop:8282/services/spatial_proxy_test

服務器端日志顯示它正在迭代，但是在客戶端僅給出了一次迭代的響應。為什么？它們對諸如ContinueParent或preservepayload等序列選項的任何更改是嗎？請告訴我。

昨晚我測試了您的方案，我的代理如下所示： 

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="AddressProxy"
       transports="https http"
       startOnLoad="true"
       trace="disable">
   <description/>
   <target>
      <inSequence>
         <property xmlns:p="http://www.example.org/Address/"
                   name="clientid"
                   expression="//p:getAddress/clientid"
                   scope="default"
                   type="STRING"/>
         <sequence key="conf:/sequencesStackOverFlow/getmpartybranch"/>
      </inSequence>
      <outSequence>
         <aggregate>
            <completeCondition>
               <messageCount min="-1" max="2"/>
            </completeCondition>
            <onComplete xmlns:add="http://ws.wso2.org/dataservice"
                        expression="//add:Addresses/add:Address">
               <send/>
            </onComplete>
         </aggregate>
      </outSequence>
   </target>
   <publishWSDL key="conf:/wsdls/Address.wsdl"/>
</proxy>

和序列中使用的序列：

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

            </send>
         </sequence>
      </target>
   </iterate>
</sequence>

您需要使用聚合介體來收集響應並創建一條唯一的消息以返回到客戶端。 檢查我的結果。 就我而言，我只需要使用轉換器介體來根據WSDL更改我的有效負載。
