Question

我试图在WSO2（4.8.1）中使用消息转发处理器。

上下文如下：

1）我在消息存储区中发送了消息 2）我使用我的消息转发处理器从商店中提取消息并调用wso2代理 3）我的代理调用外部服务

我正在测试外部服务的SOAP Fault。

这是你的代码

我的消息转发处理器配置如下

<?xml version="1.0" encoding="UTF-8"?><messageProcessor xmlns="http://ws.apache.org/ns/synapse"  class="org.apache.synapse.message.processor.impl.forwarder.ScheduledMessageForwardingProcessor" name="AnotherCapForwardMessageProcessor" targetEndpoint="AnotherCapProxyEndPoint" messageStore="OperCupIDStore">
 <parameter name="message.processor.reply.sequence">AnotherCapProcessorReply</parameter>
<parameter name="max.delivery.attempts">2</parameter>
<parameter name="client.retry.interval">5000</parameter>
<parameter name="interval">5000</parameter>
<parameter name="message.processor.fault.sequence">AnotherCapProcessorFault</parameter>
<parameter name="is.active">true</parameter>

我的代理是以下

<?xml version="1.0" encoding="UTF-8"?>
  <proxy xmlns="http://ws.apache.org/ns/synapse" name="AnotherCapProxy" transports="http https" startOnLoad="true" trace="disable">

            <property name="ERROR_EXCEPTION" expression="get-property('ERROR_EXCEPTION')"/>
        </log>
        <send/>
    </faultSequence>
</target>
<publishWSDL key="gov:wsdl/AnotherWSDL.wsdl"/>

所以我的消息处理器尝试了两次，然后自行退出。

执行日志时是以下内容......

我看到执行没有在消息处理器重试序列中交叉，并且当我关闭代理输出序列时可能出现问题。

有什么建议吗？非常感谢你提前!!!

Answer 1

当您将soap故障发送回代理outSequence中的消息处理器时，消息处理器执行它的故障序列：HTTP消息的状态代码必须具有不同于'500'的值。你应该记录它（使用属性$ axis2：HTTP_SC）

当故障序列执行'max.delivery.attempts'次时，消息处理器被取消激活，如果您希望它无限期地重新发送消息，请将此值设置为-1

错误阻止WSO2中的消息处理器的消息队列
