Thrift使用实例

Posted 2020-06-16

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。
