问题描述：

在使用thrift做开发的时候出现下面的问题：

[dp]2014-12-0217:55:23.520 WARN [Thread-4][AbstractNonblockingServer.java:520] - Exception while invoking!

org.apache.thrift.protocol.TProtocolException:Bad version in readMessageBegin

atorg.apache.thrift.server.TNonblockingServer$SelectAcceptThread.run(TNonblockingServer.java:158)[libthrift-0.9.1.jar:0.9.1]

该问题出现的原因是客户端与服务器端使用的协议格式不一样导致；

服务器端代码为：

TProcessor tProcessor = new TestThriftService.Processor<TestThriftService.Iface>(m_TestThriftService);TNonblockingServerSocket tnbSocketTransport = new TNonblockingServerSocket(m_thriftPort);TNonblockingServer.Args tnbArgs = new TNonblockingServer.Args(tnbSocketTransport);tnbArgs.processor(tProcessor);tnbArgs.transportFactory(new TFramedTransport.Factory());tnbArgs.protocolFactory(new <span style="color:#cc0000;">TBinaryProtocol</span>.Factory());// 使用非阻塞式IO，服务端和客户端需要指定TFramedTransport数据传输的方式m_server = new TNonblockingServer(tnbArgs);

客户端代码为：

TestThriftService.Client getServiceClient(){TProtocol protocol = null;m_transport = new TFramedTransport(new TSocket(THRIFT_HOST,THRIFT_PORT, 2000));// 协议要和服务端一致protocol = new TCompactProtocol(m_transport);return new TestThriftService.Client(protocol);}

这个问题是开发过程中可以避免的错误，在thrift工作于nonblock模式时，必须使用TFramedTransport，另外一点是无论采用哪种模式，在协议格式上，Thrift客户端必须与Thrift服务器保持一直
