通过 wso2 esb 中的计划任务运行的代理服务给出错误“发送回消息的意外错误”

Question

我们在 Eclipse 中使用 esb poject 在 wso2 esb 中创建了一个代理服务。该代理服务正在调用 2 个 Web 服务，第一个从遗留系统查询数据，另一个在 oracle fusion 中创建销售订单。

从soap ui 运行时，此代理服务成功执行并创建销售订单且没有错误。当从计划任务运行时，它运行并创建订单，但在 wso2carbon.log 文件中给出错误“意外错误发送消息 {org.apache.synapse.core.axis2.Axis2Sender}”。

定时任务的xml如下

<task class="org.apache.synapse.startup.tasks.MessageInjector"
        group="synapse.simple.quartz" name="testtask2">
        <trigger count="1" interval="60"/>
        <property name="proxyName" value="EslSfaOFAOMSOIntegrationPS" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="soapAction" value="operation" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="injectTo" value="proxy" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>
        <property name="to"
            value="http://10.1.6.176:8280/services/EslSfaOFAOMSOIntegrationPS.EslSfaOFAOMSOIntegrationPSHttpSoap11Endpoint" xmlns:task="http://www.wso2.org/products/wso2commons/tasks"/>

                <soapenv:Header/>
                <soapenv:Body>
                    <esl:operation/>
                </soapenv:Body>
            </soapenv:Envelope>
        </property>
    </task>

Answer 1

将<property name="OUT_ONLY" value="true"/> 放入您的EslSfaOFAOMSOIntegrationPS 代理。

而且我认为您可以删除 to 属性，因为消息被发送到proxyName 属性中给出的代理。
