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 
   
      
   
     public
   
      
   
     class
   
      TestImpl 
   
     implements
   
      Test.Iface {

   
      6 
   
     

   
      7 
   
      
   
     public
   
      
   
     void
   
      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 
   
      
   
     public
   
      
   
     class
   
      Server {

   
     14 
   
      
   
     public
   
      
   
     void
   
      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 
   
      
   
     public
   
      
   
     static
   
      
   
     void
   
      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 
   
      
   
     public
   
      
   
     class
   
      Client {

   
     11 
   
     

   
     12 
   
      
   
     public
   
      
   
     void
   
      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 
   
      
   
     public
   
      
   
     static
   
      
   
     void
   
      main(String[] args) {

   
     29 
   
      Client client 
   
     =
   
      
   
     new
   
      Client();

   
     30 
   
      client.startClient();

   
     31 
   
      }

   
     32 
   
     }
