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

1 package net.johnc.thrift;
2
3  import org.apache.thrift.TException;
4
5  publicclass TestImpl implements Test.Iface {
6
7 publicvoid ping(int length) throws TException {
8 System.out.println("calling ping ,length="+ length);
9 }
10
11 }

5.编写启动服务代码

1 package net.johnc.thrift;
2
3  import net.johnc.thrift.Test.Processor;
4
5  import org.apache.thrift.protocol.TBinaryProtocol;
6  import org.apache.thrift.protocol.TBinaryProtocol.Factory;
7  import org.apache.thrift.server.TServer;
8  import org.apache.thrift.server.TThreadPoolServer;
9  import org.apache.thrift.server.TThreadPoolServer.Args;
10  import org.apache.thrift.transport.TServerSocket;
11  import org.apache.thrift.transport.TTransportException;
12
13  publicclass Server {
14 publicvoid startServer() {
15 try {
16
17 TServerSocket serverTransport =new TServerSocket(1234);
18
19 Test.Processor process =new Processor(new TestImpl());
20
21 Factory portFactory =new TBinaryProtocol.Factory(true, true);
22
23 Args args =new Args(serverTransport);
24 args.processor(process);
25 args.protocolFactory(portFactory);
26
27 TServer server =new TThreadPoolServer(args);
28 server.serve();
29 } catch (TTransportException e) {
30 e.printStackTrace();
31 }
32 }
33
34 publicstaticvoid main(String[] args) {
35 Server server =new Server();
36 server.startServer();
37 }
38 }

 

6.编写客户端代码

1 package net.johnc.thrift;
2
3  import org.apache.thrift.TException;
4  import org.apache.thrift.protocol.TBinaryProtocol;
5  import org.apache.thrift.protocol.TProtocol;
6  import org.apache.thrift.transport.TSocket;
7  import org.apache.thrift.transport.TTransport;
8  import org.apache.thrift.transport.TTransportException;
9
10  publicclass Client {
11
12 publicvoid startClient() {
13 TTransport transport;
14 try {
15 transport =new TSocket("localhost", 1234);
16 TProtocol protocol =new TBinaryProtocol(transport);
17 Test.Client client =new Test.Client(protocol);
18 transport.open();
19 client.ping(2012);
20 transport.close();
21 } catch (TTransportException e) {
22 e.printStackTrace();
23 } catch (TException e) {
24 e.printStackTrace();
25 }
26 }
27
28 publicstaticvoid main(String[] args) {
29 Client client =new Client();
30 client.startClient();
31 }
32 }
