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();
}
}
