thrift0.9.1简单教程（包含Java服务端和Java、python客户端）

一、Thrift Java服务端和客户端

​

• 官方网站下载thrift-0.9.1.exe，用于生成代码

• 编写hello.thrift，数据结构描述文件

namespace java com.test

service  HelloWorldService {
  string sayHello(1:string username)
}

• 生成java代码：thrift-0.9.1.exe -r -gen java hello.thrift

• 将当前目录gen-java文件夹下生产代码copy到Eclipse源码目录

• 服务端实现类HelloWorldImpl，服务器启动类HelloWorldServer，客户端类HelloWorldClient

package  com.abc;

import  org.apache.thrift.TException;

public  class  HelloWorldImpl  implements  HelloWorldService.Iface {

    public  HelloWorldImpl() {
    }

    @Override
    public  String sayHello(String username)  throws  TException {
        return  "hello, "  + username;
    }

}

 

package  com.abc;

import  org.apache.thrift.TProcessor;
import  org.apache.thrift.protocol.TBinaryProtocol;
import  org.apache.thrift.server.TServer;
import  org.apache.thrift.server.TSimpleServer;
import  org.apache.thrift.transport.TServerSocket;

public  class  HelloServer {
    public  static  final  int  SERVER_PORT =  8090 ;

    public  void  startServer() {
        try  {
            System.out.println( "HelloWorld TSimpleServer start ...." );

            TProcessor tprocessor =  new  HelloWorldService.Processor<HelloWorldService.Iface>( new  HelloWorldImpl());
            TServerSocket serverTransport =  new  TServerSocket(SERVER_PORT);
            TServer.Args tArgs =  new  TServer.Args(serverTransport);
            tArgs.processor(tprocessor);
            tArgs.protocolFactory( new  TBinaryProtocol.Factory());
            TServer server =  new  TSimpleServer(tArgs);
            server.serve();
        }  catch  (Exception e) {
            System.out.println( "Server start error!!!" );
            e.printStackTrace();
        }
    }

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

}

 

package  com.abc;

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;

public  class  HelloClient {

    public  static  final  String SERVER_IP =  "localhost" ;
    public  static  final  int  SERVER_PORT =  8090 ;
    public  static  final  int  TIMEOUT =  30000 ;

    public  void  startClient(String userName) {
        TTransport transport =  null ;
        try  {
            transport =  new  TSocket(SERVER_IP, SERVER_PORT, TIMEOUT);
            // 协议要和服务端一致
            TProtocol protocol =  new  TBinaryProtocol(transport);
            // TProtocol protocol = new TCompactProtocol(transport);
            // TProtocol protocol = new TJSONProtocol(transport);
            HelloWorldService.Client client =  new  HelloWorldService.Client(protocol);
            transport.open();
            String result = client.sayHello(userName);
            System.out.println( "Thrify client result =: "  + result);
        }  catch  (TTransportException e) {
            e.printStackTrace();
        }  catch  (TException e) {
            e.printStackTrace();
        }  finally  {
            if  ( null  != transport) {
                transport.close();
            }
        }
    }

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

    }

}

 

二、python客户端调用刚才创建Java Server示例

• 创建python客户端依赖文件：thrift-0.9.1.exe -r -gen py hello.thrift

• 编写客户端文件

#!/usr/bin/env python

import  sys
sys.path.append( './gen-py' )

from  hello  import  HelloWorldService

from  thrift  import  Thrift
from  thrift.transport  import  TSocket
from  thrift.transport  import  TTransport
from  thrift.protocol  import  TBinaryProtocol

try :
  transport  =  TSocket.TSocket( 'localhost' ,  9090 )
  transport  =  TTransport.TBufferedTransport(transport)
  protocol  =  TBinaryProtocol.TBinaryProtocol(transport)
  client  =  HelloWorldService.Client(protocol)
  transport. open ()

  msg  =  client.sayHello( "jack" )
  print  "server reponse: "  +  msg

except  Thrift.TException, ex:
  print  "%s"  %  (ex.message)
finally :
  transport.close()

 

• 调用：python client.py

• 如果在调用过程出现no module named thrift.thrift错误，需要解压缩thrift源码包，进入lib/python（或lib/py）目录下运行python setup.py install
