我有一个需要限制访问的后端服务。我正在尝试使用此处描述的方法:http: //blogs.mulesoft.org/synchronous-and-asynchronous-throttling-2/
我从一个简单的传递流开始,它接收一个 SOAP 请求并转发它。当我使用 SOAPUI 实用程序点击它时,我会在一两秒内得到预期的响应。
<http:connector name="httpConnector" doc:name="HTTP\HTTPS">
<receiver-threading-profile maxThreadsActive="1" maxBufferSize="100" />
</http:connector>
<jms:activemq-connector name="amqConnector" brokerURL="tcp://localhost:61616" specification="1.1" doc:name="AMQ" />
<flow name="Flow1" processingStrategy="synchronous" doc:name="Flow1">
<http:inbound-endpoint exchange-pattern="request-response"
host="localhost" port="8088" path="test" doc:name="HTTP"
mimeType="text/xml" encoding="UTF-8" connector-ref="httpConnector"/>
<http:outbound-endpoint
address="http://dnbdirect-api.dnb.com/DnBAPI-11"
exchange-pattern="request-response" doc:name="HTTP" mimeType="text/xml"/>
</flow>
如果我随后将出站呼叫移动到单独的流并添加请求-回复块,则行为会发生变化。我没有得到回复(我也没有从记录器中得到“队列后”消息),并且 SOAPUI 最终超时。
<http:connector name="httpConnector" doc:name="HTTP\HTTPS">

<message-properties-transformer doc:name="Message Properties">
<add-message-property key="AMQ_SCHEDULED_DELAY" value="5000"/>
</message-properties-transformer>
<logger message="Before queue" level="INFO"/>
<request-reply>
<jms:outbound-endpoint queue="request" connector-ref="amqConnector"></jms:outbound-endpoint>
<jms:inbound-endpoint queue="response" connector-ref="amqConnector"></jms:inbound-endpoint>
</request-reply>
<logger message="After queue" level="INFO"/>
</flow>
<flow name="flow2" doc:name="Flow2">
<jms:inbound-endpoint queue="request" connector-ref="amqConnector" doc:name="JMS"/>
<http:outbound-endpoint
address="http://dnbdirect-api.dnb.com/DnBAPI-11"
exchange-pattern="request-response" doc:name="HTTP" mimeType="text/xml" />
</flow>
如果我取消对后端服务的调用,则限制行为会起作用,因为我会看到延迟。但我无法让它与那里的服务调用一起工作。
我错过了什么?
