Thrift使用实例

首先下载thrift.exe,和对应lib包。注意版本一定要一致。

否则编译会不识别出现错误。

可能会出现org.slf4j这个错误,那么你要把slf4j-api.jar下载下来引入到你的project中

namespace java com.nerd.thrift.service
/**
*
*/
service sayThriftService{
void say();
}

通过在命令行中转到 thrift-1.8.0.exe -gen java  sayThriftService

在磁盘目录中(com.nerd.thrift.service)可发现这个脚本对应的java代码

例如以下:

public class sayThriftService {

  /**
*
*/
public interface Iface { public void say() throws org.apache.thrift.TException; } public interface AsyncIface { public void say(org.apache.thrift.async.AsyncMethodCallback<AsyncClient.say_call> resultHandler) throws org.apache.thrift.TException; } public static class Client extends org.apache.thrift.TServiceClient implements Iface {
public static class Factory implements org.apache.thrift.TServiceClientFactory<Client> {
public Factory() {}
public Client getClient(org.apache.thrift.protocol.TProtocol prot) {
return new Client(prot);
}
public Client getClient(org.apache.thrift.protocol.TProtocol iprot, org.apache.thrift.protocol.TProtocol oprot) {
return new Client(iprot, oprot);
}
}
...................省略(详细看自己的生成代码)

先写一个Server类:

package com.nerd.clq;

import org.apache.thrift.TException;
import org.apache.thrift.TProcessor;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocolFactory;
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 com.nerd.clq.thrift.sayThriftService;
import com.nerd.clq.thrift.sayThriftService.Iface; public class Server implements sayThriftService.Iface{
private static TServer server;
@Override
public void say() throws TException {
System.out.println(System.currentTimeMillis());
} public static void main(String[] args) throws TException {
Server server1 = new Server();
TServerSocket serverTransport = new TServerSocket(8080);
TProtocolFactory proFactory = new TBinaryProtocol.Factory();
sayThriftService.Processor<Iface> processor = new sayThriftService.Processor<Iface>(server1);
Args arg = new Args(serverTransport) {
}.protocolFactory(proFactory).processor(processor);
server = new TThreadPoolServer(arg);
//启动服务(先启动这个类,然后启动client类)
server.serve();
}
}

client客户端类

package com.nerd.clq;

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 com.nerd.clq.thrift.sayThriftService; public class Client {
public static void main(String[] args) throws TException {
TTransport transport = new TSocket("localhost", 8080);
TProtocol protocol = new TBinaryProtocol(transport);
sayThriftService.Client client = new sayThriftService.Client(protocol);
transport.open();
client.say();
transport.close();
} }

server编写的一般步骤:

1. 创建Handler

2. 基于Handler创建Processor

3. 创建Transport

4. 创建Protocol方式

5. 基于Processor, Transport和Protocol创建Server

6. 执行Server
client编写的一般步骤:

1. 创建Transport

2. 创建Protocol方式

3. 基于Transport和Protocol创建Client

4. 执行Client的方法
创建Transport的时候。一般都须要创建对应的Socket。
