thrift:   系统之间的数据的传输， 调用对外暴露的接口，然后获取封装的具体的业务数据结果。 一种比较灵活的RPC。

namespace java com.thrift.demo
    
    service  HelloWorldService {
    
         string sayHello(1:string username)
    
    
    }

1）安装thrift：到thrift官网下载exe文件，然后将文件重命名为thrift.exe,拷贝到c:\\windows目录下(或者任何目录下)，然后就可以在dos环境下使用了

c:\\windows>thrift -gen java D:\\mywork\\javaProject\\thriftTest\\test.thrift ，输出的java文件默认输出到当前目录下c:\\windows，也可以使用-o参数指定输出路径

创建上面的一个thrift文件，  使用命令生成HelloWorldService.java文件。

加载需要的包。

<dependencies>
      
           <dependency>
                <groupId>org.apache.thrift</groupId>
                <artifactId>libthrift</artifactId>
                <version>0.9.1</version>
          </dependency>
          <dependency>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-log4j12</artifactId>
                <version>1.5.8</version>
          </dependency>
      
       </dependencies>

实现接口，

package com.thrift.demo;
    import org.apache.thrift.TException;
    
    
    public class HelloWorldImpl implements HelloWorldService.Iface{
    
    	@Override
    	public String sayHello(String username) throws TException {
    		 
    		
    		 return "Hi," + username + " ,我是服务端实现类";
    	}
    
    }

这个就是暴露给另外系统的接口， 里面也就是自己的业务逻辑代码处理。

服务类如下：

package com.test;
    
    import org.apache.thrift.TProcessor;
    import org.apache.thrift.protocol.TCompactProtocol;
    import org.apache.thrift.server.TNonblockingServer;
    import org.apache.thrift.server.TServer;
    import org.apache.thrift.server.TSimpleServer;
    import org.apache.thrift.transport.TFramedTransport;
    import org.apache.thrift.transport.TNonblockingServerSocket;
    import org.apache.thrift.transport.TServerSocket;
    
    import com.thrift.demo.HelloWorldImpl;
    import com.thrift.demo.HelloWorldService;
    
    public class HelloServerDemo {
    
    	 
    	public static void main(String[] args) {
    		  
    		HelloServerDemo  serverDemo = new HelloServerDemo();
    		//serverDemo.startServer();
    		 
    		serverDemo.startAsyServer();
    	}
    	
    	
    	public void startServer(){
    		try{
    			HelloWorldService.Processor<HelloWorldService.Iface>  tprocessor = new HelloWorldService.Processor<HelloWorldService.Iface>(new HelloWorldImpl());
    			// 简单单线程服务模型 ，一般用于测试
    			TServerSocket serverTransport = new TServerSocket(8090);
    			TServer.Args tArgs = new TServer.Args(serverTransport);
    	        tArgs.processor(tprocessor);
    	        // TProtocol 协议要对的上。
    	        tArgs.protocolFactory(new TCompactProtocol.Factory());
                TServer server = new TSimpleServer(tArgs);
                server.serve();
    		}catch(Exception e){
    			 
    			System.out.println("Server start error!!!");
                e.printStackTrace();
    		}
    	}
    	
    	
    	/**
    	 * 
    	* @Title: startAsyServer 
    	* @Description: TODO    异步客户端对应的服务端
    	* @param     设定文件 
    	* @return void    返回类型 
    	* @throws
    	 */
    	public void startAsyServer(){
    		
    		try {
    			System.out.println("HelloWorld TNonblockingServer start ....");
    
    			TProcessor tprocessor = new HelloWorldService.Processor<HelloWorldService.Iface>(
    					new HelloWorldImpl());
    
    			TNonblockingServerSocket tnbSocketTransport = new TNonblockingServerSocket(
    					8090);
    			TNonblockingServer.Args tnbArgs = new TNonblockingServer.Args(
    					tnbSocketTransport);
    			tnbArgs.processor(tprocessor);
    			tnbArgs.transportFactory(new TFramedTransport.Factory());
    			tnbArgs.protocolFactory(new TCompactProtocol.Factory());
    
    			// 使用非阻塞式IO，服务端和客户端需要指定TFramedTransport数据传输的方式
    			TServer server = new TNonblockingServer(tnbArgs);
    			server.serve();
    
    		} catch (Exception e) {
    			System.out.println("Server start error!!!");
    			e.printStackTrace();
    		}
    		
    		
    	}
    	
    	
    
    }

客户端：（单线程简单测试）

package com.test;
    
    import org.apache.thrift.protocol.TCompactProtocol;
    import org.apache.thrift.protocol.TProtocol;
    import org.apache.thrift.transport.TSocket;
    import org.apache.thrift.transport.TTransport;
    
    import com.thrift.demo.HelloWorldService;
    
    
    /***
     * 
    
        TBinaryProtocol : 二进制格式.
        TCompactProtocol : 压缩格式
        TJSONProtocol : JSON格式
        TSimpleJSONProtocol : 提供JSON只写协议, 生成的文件很容易通过脚本语言解析
    
    
        
        thrift生成代码
              实现接口Iface
        TSimpleServer服务模型
        TThreadPoolServer 服务模型
        TNonblockingServer 服务模型
        THsHaServer服务模型
              异步客户端
    
    *
     */
    public class HelloClientDemo {
    
    	
    	public static void main(String[] args) {
    		 
    		try{
    			 TTransport   transport = new TSocket("127.0.0.1", 8090, 30000);
    			 TProtocol protocol = new TCompactProtocol(transport);
    			 HelloWorldService.Client client = new HelloWorldService.Client(
    	                    protocol);
    			 transport.open();
    	         String result = client.sayHello("小强");
    	         System.out.println("Thrift client result =: " + result);
    		}catch(Exception e){
    			e.printStackTrace();
    		}
    		 
    	}
    
    }

异步客户端：（对应的是服务端的startAsyServer这个方法）

package com.test;
    
    import java.util.concurrent.CountDownLatch;
    import java.util.concurrent.TimeUnit;
    
    import org.apache.thrift.TException;
    import org.apache.thrift.async.AsyncMethodCallback;
    import org.apache.thrift.async.TAsyncClientManager;
    import org.apache.thrift.protocol.TCompactProtocol;
    import org.apache.thrift.protocol.TProtocolFactory;
    import org.apache.thrift.transport.TNonblockingSocket;
    import org.apache.thrift.transport.TNonblockingTransport;
    
    import com.thrift.demo.HelloWorldService;
    import com.thrift.demo.HelloWorldService.AsyncClient.sayHello_call;
    
    public class HelloAsynClientDemo {
    
    	public static final String SERVER_IP = "localhost";
    	public static final int SERVER_PORT = 8090;
    	public static final int TIMEOUT = 30000;
    
    	
    	
    	public static void main(String[] args) {
    		HelloAsynClientDemo client = new HelloAsynClientDemo();
    		client.startClient("Michael");
    	}
    	
    	
    	/**
    	 *
    	 * @param userName
    	 */
    	public void startClient(String userName) {
    		try {
    			TAsyncClientManager clientManager = new TAsyncClientManager();
    			TNonblockingTransport transport = new TNonblockingSocket(SERVER_IP,
    					SERVER_PORT, TIMEOUT);
    
    			TProtocolFactory tprotocol = new TCompactProtocol.Factory();
    			HelloWorldService.AsyncClient asyncClient = new HelloWorldService.AsyncClient(
    					tprotocol, clientManager, transport);
    			System.out.println("Client start .....");
    
    			CountDownLatch latch = new CountDownLatch(1);
    			AsynCallback callBack = new AsynCallback(latch);
    			System.out.println("call method sayHello start ...");
    			asyncClient.sayHello(userName, callBack);
    			System.out.println("call method sayHello .... end");
    			boolean wait = latch.await(30, TimeUnit.SECONDS);
    			System.out.println("latch.await =:" + wait);
    		} catch (Exception e) {
    			e.printStackTrace();
    		}
    		System.out.println("startClient end.");
    	}
    	
    	
    	public class AsynCallback implements AsyncMethodCallback<sayHello_call>{
    		private CountDownLatch latch;
    
    		public AsynCallback(CountDownLatch latch) {
    			this.latch = latch;
    		}
    
    		@Override
    		public void onComplete(sayHello_call response) {
    			System.out.println("onComplete");
    			try {
    				// Thread.sleep(1000L * 1);
    				System.out.println("AsynCall result =:"
    						+ response.getResult().toString());
    			} catch (TException e) {
    				e.printStackTrace();
    			} catch (Exception e) {
    				e.printStackTrace();
    			} finally {
    				latch.countDown();
    			}
    		}
    
    		@Override
    		public void onError(Exception exception) {
    			System.out.println("onError :" + exception.getMessage());
    			latch.countDown();
    		}
    	}
    
    }

总体感觉， 这种形式的数据传输更加的简单和方便。
