具有持久套接字的Mule TCP轮询监听器？

时间：2014-01-17 23:17:23

标签： tcp mule

我正在尝试将Mule配置为连接到外部TCP服务器，然后通过已建立的连接接收流式消息（XML文档）。我已经创建了一个从InputStream中提取XML的自定义协议，但是，TCP轮询连接器似乎正在关闭套接字，然后重新打开套接字，因为我的TCP服务器不断通知我新的连接。下面是我的Mule Flow，任何人都可以建议如何让Mule建立TCP连接并保持连接打开，在打开连接的消息后轮询消息？

UPDATE 根据要求，我启用了登录org.mule.transport.tcp，结果如下（为简洁起见，删除了一些输出）：

2 个答案:

答案 0 :(得分：0)

我真的很惊讶套接字没有保持打开状态：在阅读3.4.0的源代码之后，很明显如果连接器上有keepSendSocketOpen=true，套接字将返回到池中并保留在钝化时打开（参见：https://github.com/mulesoft/mule/blob/mule-3.4.0/transports/tcp/src/main/java/org/mule/transport/tcp/TcpConnector.java#L211和https://github.com/mulesoft/mule/blob/mule-3.4.0/transports/tcp/src/main/java/org/mule/transport/tcp/AbstractTcpSocketFactory.java#L68）

您可以将org.mule.transport.tcp记录器设置为DEBUG并跟踪发生的情况吗？

答案 1 :(得分：0)

好的，所以写完我自己的协议（从流中的每个消息去掉前2个字节，第二个是消息长度），然后使用MuleStudio调试每个步骤完成代码后，我注意到套接字正在“释放”到池中两次，第二次池确定套接字处于空闲状态并关闭所述套接字。这当然不应该发生。套接字被“释放”两次的原因是因为MessageDispatcher确定套接字没有流式传输，下一个问题变成了“如何将套接字设置为流式传输”。事实证明，在我的自定义协议中，当'read'方法传递给InputStream时，我需要将InputStream转换为TcpInputStream，然后使用布尔参数'true'调用它的'setStreaming'方法。这一切看起来都非常混乱，因为我的协议，没有创建InputStream应该不在一般实践中修改InputStream。我原本预计连接器上某处会有一个XML标志来确定流式传输与非流式传输，或者在协议本身设置一些值，将其标识为流式传输协议。我认为我做错了什么，并且'read'方法虽然有效但不适合干扰流媒体/非流媒体，但是在查看Mule流媒体协议的源代码时，这是它是如何完成的 - 所以我只能假设这是故意的，并且会要求在将来的版本中以更干净，适当或至少明显的方式完成。
