做一个HelloWorld的例子，基本上跑通了。

过程如下：

环境准备：

开始我选择的是最新的版本：Apache Thrift v0.9.0 ，

1.在linux下有一些lib库没有安装成功，问题： configure: error: "Error: libcrypto required."

2.在windows下了一个windows版本, 运行 thrift-0.9.0.exe -r --gen java Hello.thrift ，发现不是win32版本。

3.重新下载了0.7.0 windows版本，此版本OK，可以在win 32使用

4.下载相关jar包：org.apache.servicemix.bundles.libthrift-0.7.0_1.jar ， libfb303-0.7.0.jar

5.接下来就在windows环境下开发

例子：

1. thrift接口定义:Hello.thrift

 namespace java service.demo
service Hello{

    string helloString(1:string para)
    i32 helloInt(1:i32 para)
    bool helloBoolean(1:bool para)
    void helloVoid()
    string helloNull() 

} 

2. 生成java接口
     thrift-0.7.0.exe -r --gen java Hello.thrift
     会生如下代码：

/**
 * Autogenerated by Thrift Compiler (0.7.0)
 *
 * DO NOT EDIT UNLESS YOU ARE SURE THAT YOU KNOW WHAT YOU ARE DOING
 */
package service.demo;

import java.util.List;
import java.util.ArrayList;
import java.util.Map;
import java.util.HashMap;
import java.util.EnumMap;
import java.util.Set;
import java.util.HashSet;
import java.util.EnumSet;
import java.util.Collections;
import java.util.BitSet;
import java.nio.ByteBuffer;
import java.util.Arrays;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Hello {

  public interface Iface {

    public String helloString(String para) throws org.apache.thrift.TException;

    public int helloInt(int para) throws org.apache.thrift.TException;

    public boolean helloBoolean(boolean para) throws org.apache.thrift.TException;

    public void helloVoid() throws org.apache.thrift.TException;

    public String helloNull() throws org.apache.thrift.TException;

  }
  .....此处省略，详细请看自己生成文件
 

}

 

3. 将生成的service.demo.Hello.java的导入eclipse中

4. 编写Server端实现类HelloServiceImpl： 即 Hello.Iface 的实现

package service.demo;

import org.apache.thrift.TException;

public class HelloServiceImpl implements Hello.Iface {
    @Override
    public boolean helloBoolean(boolean para) throws TException {
        return para;
    }

    @Override
    public int helloInt(int para) throws TException {
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        return para+1;
    }

    @Override
    public String helloNull() throws TException {
        return null;
    }

    @Override
    public String helloString(String para) throws TException {
        return para;
    }

    @Override
    public void helloVoid() throws TException {
        System.out.println("Hello World");
    }
}

5. Server启动类: HelloServiceServer

package service.server;

import service.demo.Hello.Processor;

import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TBinaryProtocol.Factory;
import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TThreadPoolServer;
import org.apache.thrift.server.TThreadPoolServer.Args;
import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TTransportException;

import service.demo.Hello;
import service.demo.HelloServiceImpl;

public class HelloServiceServer {
    public void startServer() {
        try {

            TServerSocket serverTransport = new TServerSocket(1234);

            Hello.Processor process = new Processor(new HelloServiceImpl());

            Factory portFactory = new TBinaryProtocol.Factory(true, true);
            Args args = new Args(serverTransport);
            args.processor(process);
            args.protocolFactory(portFactory);

            TServer server = new TThreadPoolServer(args);
            server.serve();
        } catch (TTransportException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        HelloServiceServer server = new HelloServiceServer();
        server.startServer();
    }
}

6. 客户端类：HelloClient

package service.client;

import org.apache.thrift.TException;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;
import org.apache.thrift.transport.TTransportException;

import service.demo.Hello;

public class HelloClient {

    public void startClient() {
        TTransport transport;
        try {
            transport = new TSocket("localhost", 1234);
            TProtocol protocol = new TBinaryProtocol(transport);
            Hello.Client client = new Hello.Client(protocol);
            transport.open();
            System.out.println(client.helloInt(12));
            transport.close();
        } catch (TTransportException e) {
            e.printStackTrace();
        } catch (TException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        HelloClient client = new HelloClient();
        client.startClient();
    }
}

7.运行:

a. 启动HelloServiceServer

b. 启动HelloClient
运行结果：client端会显示13  即：helloInt是进行+1操作。


附：c#客户端代码(参考http://blog.youkuaiyun.com/kc87654321/article/details/7226675)
1.   thrift -gen csharp Hello.thrift
2.   导入thrift的C#库工程：/thrift/lib/
3.   将生成的Hello.cs加入到项目
4.   客户端代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Thrift.Transport;
using Thrift.Protocol;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
  
            TTransport transport = new TSocket("localhost", 1234); 
            TProtocol protocol = new TBinaryProtocol(transport); 
            Hello.Client client = new Hello.Client(protocol); 
            transport.Open(); 
            Console.WriteLine("Client calls .....");
            while (true)
            {
                String str=Console.ReadLine();
                    
                Console.WriteLine(client.helloInt(Convert.ToInt32(str)));

            }
            transport.Close();

            Console.ReadLine();
        }
    }
}
