Thrift java服务器与客户端示例

简单的实现一个PING的功能

1.安装thrift

http://thrift.apache.org/download/

人人网镜像下载:

http://labs.renren.com/apache-mirror/thrift/0.6.1/thrift-0.6.1.exe

2.编写Thrift文件（定义接口，结构，异常等）,保存为test.thrift

?

namespace java net.johnc.thrift

service Test{

 

 void ping(1: i32 length)

 

}

3.生成接口代码

把thrift-0.6.1.exe和test.thrift文件放在同一个目录，当然也可以把thrift-0.6.1.exe文件放进环境变量

进入DOS命令执行：thrift-0.6.1.exe --gen java test.thrift

生成文件 gen-java/net/johnc/thrift/Test.java

4.编写服务端接口实现类

在POM.xml文件加入以下依赖：

?

<dependency>

      <groupId>org.apache.thrift</groupId>

      <artifactId>libthrift</artifactId>

      <version>0.6.1</version>

  </dependency>

  把生成的Test.java复制到项目下

package net.johnc.thrift;

 import org.apache.thrift.TException;

 public class TestImpl implements Test.Iface {

    public void ping(int length) throws TException {
        System.out.println("calling ping ,length=" + length);
    }

}

5.编写启动服务代码

package net.johnc.thrift;

 import net.johnc.thrift.Test.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;

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

            TServerSocket serverTransport = new TServerSocket(1234);

            Test.Processor process = new Processor(new TestImpl());

            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) {
        Server server = new Server();
        server.startServer();
    }
}

6.编写客户端代码

package net.johnc.thrift;

 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 Client {

    public void startClient() {
        TTransport transport;
        try {
            transport = new TSocket("localhost", 1234);
            TProtocol protocol = new TBinaryProtocol(transport);
            Test.Client client = new Test.Client(protocol);
            transport.open();
            client.ping(2012);
            transport.close();
        } catch (TTransportException e) {
            e.printStackTrace();
        } catch (TException e) {
            e.printStackTrace();
        }
    }

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