Thrift 中以GBK传输中文字符跟分词服务搭建

Thrift 中以GBK传输中文字符和分词服务搭建
     项目中需要将分词做成线上服务形式，服务后端用c++实现，客户端用java实现，来调用分词的服务。由于分词程序默认是以GBK编码为准，但是JAVA读写字符串的固定编码为utf-8，需要在数据传输的时候以GBK编码方式传输，Thrift 的JAVA库中不支持以GBK方式传输字符串，而且预期不会增加如此功能(Support non-UTF-8 in Java and C#)，原因参考Support non-UTF-8 in Java；c/c++中传输的字符串是字节序列，不存在编码的问题。通过阅读TProtocol相关代码，只需要重写readString 和writeString中的字符串读写编码方式即可，重写的类的完整实现如下：
int main(int argc, char **argv) { int port = 9999; shared_ptr/<spservicehandler> handler(new SpServiceHandler() ); shared_ptr/<tprocessor> processor(new SpServiceProcessor(handler)); shared_ptr/<tservertransport> serverTransport(new TServerSocket(port)); shared_ptr/<ttransportfactory> transportFactory(new TBufferedTransportFactory()); shared_ptr/<tprotocolfactory> protocolFactory(new TCompactProtocolFactory()); int multinum = 100; shared_ptr/<threadmanager> threadManager = ThreadManager::newSimpleThreadManager(multinum); shared_ptr/<posixthreadfactory> threadFactory = shared_ptr/<posixthreadfactory>(new PosixThreadFactory()); threadManager-/>threadFactory(threadFactory); threadManager-/>start(); printf("start segmentor server...%d thread\n", multinum); TThreadPoolServer server(processor, serverTransport, transportFactory, protocolFactory, threadManager); server.setTimeout(20); server.serve(); return 0;}</posixthreadfactory></posixthreadfactory></threadmanager></tprotocolfactory></ttransportfactory></tservertransport></tprocessor></spservicehandler>
