IDL文件
编写IDL文件 EchoService.thrift

namespace java service.demoservice EchoService {    string echo(1:string para)   }

编译

thrift -o <output directory> -gen java EchoService.thrift

实现接口

public class EchoServiceImpl implements EchoService.Iface {    public String echo(String para) throws TException {        return para;    }}

服务端

public class HelloServiceServer {    public static void main(String arge[]) {        try {            // 设置服务端口为 7911            TServerSocket serverTransport = new TServerSocket(7911);            // 设置协议工厂为 TBinaryProtocol.Factory            TBinaryProtocol.Factory proFactory = new TBinaryProtocol.Factory();            // 关联处理器与 Hello 服务的实现            TProcessor processor = new HelloService.Processor(new HelloServiceImpl());            TServer server = new TThreadPoolServer(                                new TThreadPoolServer.Args(serverTransport)                                .protocolFactory(proFactory)                                .processor(processor)                             );            System.out.println("Start server on port 7911...");            server.serve();        } catch (TTransportException e) {            e.printStackTrace();        }    }}

客户端

public class HelloServiceClient {    public static void main(String args[]) {        try {            // 设置调用的服务地址为本地，端口为 7911            TTransport transport = new TSocket("localhost", 7911);            transport.open();            // 设置传输协议为 TBinaryProtocol            TProtocol protocol = new TBinaryProtocol(transport);            HelloService.Client client = new HelloService.Client(protocol);            // 调用服务的 helloVoid 方法            System.out.print(client.echo("hello"));            transport.close();        } catch (TTransportException e) {            e.printStackTrace();        } catch (TException e) {            e.printStackTrace();        }    }}

异步IO

服务端

public static void main(String[] args) {        try {            //传输通道 - 非阻塞方式            TNonblockingServerSocket serverTransport = new TNonblockingServerSocket(7911);            //异步IO，需要使用TFramedTransport，它将分块缓存读取。            TTransportFactory transportFactory = new TFramedTransport.Factory();            //使用高密度二进制协议            TProtocolFactory proFactory = new TCompactProtocol.Factory();            //设置处理器 HelloImpl            TProcessor processor = new Hello.Processor(new HelloImpl());            //创建服务器            TServer server = new TThreadedSelectorServer(                    new Args(serverTransport)                    .protocolFactory(proFactory)                    .transportFactory(transportFactory)                    .processor(processor)                );            System.out.println("Start server on port 7911...");            server.serve();        } catch (Exception e) {            e.printStackTrace();        }    }

客户端

/** 调用[非阻塞IO]服务，异步 */    public static void main(String[] args) {        try {            //异步调用管理器            TAsyncClientManager clientManager = new TAsyncClientManager();            //设置传输通道，调用非阻塞IO。            final TNonblockingTransport transport = new TNonblockingSocket("localhost", 7911);              //设置协议            TProtocolFactory protocol = new TCompactProtocol.Factory();              //创建Client            final Hello.AsyncClient client = new Hello.AsyncClient(protocol, clientManager, transport);            // 调用服务             System.out.println("开始：" + System.currentTimeMillis());            client.helloBoolean(false, new AsyncMethodCallback<Hello.AsyncClient.helloBoolean_call>() {                public void onError(Exception exception) {                    System.out.println("错误1： " + System.currentTimeMillis());                }                public void onComplete(helloBoolean_call response) {                    System.out.println("完成1： " + System.currentTimeMillis());                    try {                        client.helloBoolean(false, new AsyncMethodCallback<Hello.AsyncClient.helloBoolean_call>() {                            public void onError(Exception exception) {                                System.out.println("错误2： " + System.currentTimeMillis());                            }                            public void onComplete(helloBoolean_call response) {                                System.out.println("完成2： " + System.currentTimeMillis());                                transport.close();                            }                        });                    } catch (TException e) {                        e.printStackTrace();                    }                }            });            System.out.println("结束：" + System.currentTimeMillis());            Thread.sleep(5000);        } catch (Exception e) {            e.printStackTrace();        }    }

跨语言调用

reference:
http://itindex.net/detail/52661-thrift-%E8%AF%AD%E8%A8%80-%E5%BC%80%E5%8F%91

例如本文中使用c++调用对应的java服务。服务端和客户端的请求调用是通过网络完成的，因此需要保证，请求协议、编码格式以及服务调用的格式都保持一致。
因此针对跨语言的调用，只要生成对应的服务接口，按照不同语言提供的客户端服务接口编写对应的代码。保持协议和编码合适一致即可。

安全协议

使用SSL安全传输协议

服务端

TSSLTransportParameters parameters = new TSSLTransportParameters();params.setKeyStore("../.keystore", "thrift" , null, null);TServerTransport serverTransport = TSSLTransportFactory.getServerSocket(9091, 0, null, param);

客户端

TSSLTransportParameters parameters = new TSSLTransportParameters();params.setKeyStore("../.keystore", "thrift" , "SunX509", "JKS");TServerTransport serverTransport = TSSLTransportFactory.getServerSocket("localhost", 9091, 0, param);
