禁止Mule ESB阻止一些請求

Question

有時（非常頻繁），ESB禁止某些SOAP請求。我如何阻止騾子這樣做？我不知道阻塞的原因是什麼。

這是多麼我已經配置HTTP偵聽器在騾子的配置：

<http:listener-config name="HTTP_listener" host="${MachineName}" port="${InboundPort}" doc:name="HTTP listener Configuration" />  
<flow name="etryFlow" > 
    <http:listener allowedMethods="POST" config-ref="HTTP_listener" path="/{name}" doc:name="HTTP"/> 

    <set-payload value="#[app.registry.pairFactory.createInputStreamWithStringKeyInstance(message.inboundProperties['http.uri.params']['name'],payload))]" />         
    <jms:outbound-endpoint connector-ref="jms-connector" ref="UnsortedOrders" /> 
    <logger level="INFO" doc:name="Logger" message="****Entry****" />       
</flow> 

注：被取締的請求被轉換成BlockingTransferInputStream而不是BufferInputStream。

謝謝。

**編輯**

這是createInputStreamWithStringKeyInstance實現：

public static Pair<String, byte[]> createByteArrayWithStringKeyInstance(String key, byte value[]) throws IOException { 
    return new Pair<String, byte[]>(key, value); 
} 

和Pair.java是一個簡單的序列化的類（同JavaFX.Pair） 注：輸入是一個XML SOAP

Answer 1

假設createInputStreamWithStringKeyInstance（你沒有描述，所以它真的很難幫你）返回InputStream，騾結束了建立一個JMS StreamMessage（每this call）。

從騾子代碼，你可以看到它水渠流的有效載荷送入這個邏輯StreamMessage：

while ((len = value.read(buffer)) != -1) 
{ 
    streamMessage.writeBytes(buffer, 0, len); 
} 

這是很好的，提供由createInputStreamWithStringKeyInstance返回的流不會做後面的任何特殊業務現場。

另請注意，JMS StreamMessage可能不是您想要的。你讀過its Javadoc嗎？它說：

StreamMessage對象用於發送Java編程語言中的原語類型流。

我很確定你想用JMS BytesMessage。如果有效負載是byte[]（根據上述鏈接轉換邏輯），Mule會創建此類消息，因此您寧願在jms:outbound-endpoint之前有<object-to-byte-array-transformer/>。
