thrift的简单实现

1.使用windows实现，首先在apache官网下载一个thrift的编译工具，在项目中建一个文件叫add.thrift的文件，内容如下：

namespace java com.vipshop.sample.server

service AdditionService{
      i32 add(1:i32 n1,2:i32 n2)
}

使用下载的thrift工具进行编译，命令如下thrift --gen java add.thrift(本人使用的是java实现)  编译后会生成一个叫AdditionService.java 的文件

2 把这个文件添加到项目中（需要的jar包有两个，一个是thrift的jar包，要自己去生成，一个是slf4j  jar包），目录结构如下：

3 新建一个名叫AdditionServiceHandle的java文件，来实现我们在AdditionService中所需要实现的方法

import org.apache.thrift.TException;

public class AdditionServiceHandle implements AdditionService.Iface{

    @Override
    public int add(int n1, int n2) throws TException {
        // TODO Auto-generated method stub
        return n1+n2;
    }

}

4 编写服务端，代码如下

import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TSimpleServer;
import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TServerTransport;

public class MyServer {

    public static void startsImpleServer(AdditionService.Processor<AdditionServiceHandle> processor){
        try
        {
            TServerTransport serverTransport=new TServerSocket(9090);
            TServer server=new TSimpleServer(new TServer.Args(serverTransport).processor(processor));

            System.out.println("starting the simple server....");
            server.serve();
        }
        catch (Exception e)
        {
            // TODO: handle exception
        }
    }

    public static void main(String[] args) {
        startsImpleServer(new AdditionService.Processor<AdditionServiceHandle>(new AdditionServiceHandle()));
    }

}

5 编写客户端

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

public class AdditionClient {
    public static void main(String[] args) {
        try
        {
            TTransport transport;
            transport=new TSocket("localhost",9090);
            transport.open();

            TProtocol protocol=new TBinaryProtocol(transport);
            AdditionService.Client client=new AdditionService.Client(protocol);
            System.out.println(client.add(100, 200));
            transport.close();
        }
        catch (Exception e)
        {
            // TODO: handle exception
        }
    }
}

6运行服务器端和客户端，结果客户端为300
