当我们使用Thrift 通信的时候，服务端有时候需要注册多个类，去实现通信，这时候我们就不能再使用单一Processor的方式，就要使用多个Processor，那么如何去实现呢？

多个Process

服务端

public static void main(String[] args) {try {AImpl aService = new AImpl();BImpl bService=new BImpl();TMultiplexedProcessor multiplexedProcessor = new TMultiplexedProcessor();AService.Processor<AImpl> aProcessor = new AService.Processor<>(aService);multiplexedProcessor.registerProcessor("aService", aProcessor);BService.Processor<BImpl> bProcessor = new BService.Processor<>(bService);multiplexedProcessor.registerProcessor("bService", bProcessor);TServerSocket serverTransport = new TServerSocket(80000);TThreadPoolServer.Args serverArgs = new TThreadPoolServer.Args(serverTransport);serverArgs.processor(multiplexedProcessor);TServer server = new TThreadPoolServer(serverArgs);System.out.println("Starting the multi-processor server...");server.serve();} catch (Exception e) {e.printStackTrace();System.out.println(e.getMessage());}}

客户端

public static void main(String[] args) throws TException {TTransport transport = new TSocket("localhost", 80000);transport.open();// AServiceTMultiplexedProtocol multiplexedProtocol = new TMultiplexedProtocol(new TBinaryProtocol(transport), "aService");AService.Client aClient = new AService.Client(multiplexedProtocol);aClient.method();System.out.println("Calling AService method...");// BServicemultiplexedProtocol = new TMultiplexedProtocol(new TBinaryProtocol(transport), "bService");BService.Client bClient = new BService.Client(multiplexedProtocol);BClient.method();System.out.println("Calling SystemLogService method...");transport.close();}

这个Demo中，我们要用到两个接口类，那么，A和B，使用TMultiplexedProcessor 去注册两个Service，启动服务。

单个Process

服务端

            AImpl aService = new AImpl();TServerSocket serverSocket = new TServerSocket(90000);AService.Processor<AImpl> aProcessor= new AService.Processor<>(aService);TThreadPoolServer.Args serverArg = new TThreadPoolServer.Args(serverSocket);serverArg.processor(aProcessor);TThreadPoolServer server = new TThreadPoolServer(serverArg);server.serve();

客户端

 TTransport transport = new TSocket("localhost", 90000);transport.open();TBinaryProtocol protocol = new TBinaryProtocol(transport);AService.Client aClient = new AService.Client(protocol);aclient.method();

附单个process的方式。
