[一]、概述

Thrift是一个软件框架，用来进行可扩展且跨语言的服务的开发。它结合了功能强大的软件堆栈和代码生成引擎，以构建在 C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, and OCaml 等等编程语言间无缝结合的、高效的服务。

Thrift最初由facebook开发，07年四月开放源码，08年5月进入apache孵化器。thrift允许你定义一个简单的定义文件中的数据类型和服务接口。以作为输入文件，编译器生成代码用来方便地生成RPC客户端和服务器通信的无缝跨编程语言。

官网地址：thrift.apache.org

[二]、下载配置

到官网下载最新版本，截止今日（2012-06-11）最新版本为0.8.0.

1. 如果是Maven构建项目的，直接在pom.xml 中添加如下内容：

1
 <dependency> 
 
   
2
 <groupId>org.apache.thrift</groupId> 
 
   
3
 <artifactId>libthrift</artifactId> 
 
   
4
 <version>0.8.0</version> 
 
   
5
 </dependency>

2.如果自己编译lib包，把下载的压缩包解压到X:盘，然后在X:\thrift-0.8.0\lib\java 目录下运行ant进行自动编译，会在X:\thrift-0.8.0\lib\java\build\ 目录下看到编译好的lib包：libthrift-0.8.0.jar

[三]、基本概念

1.数据类型

基本类型：

bool：布尔值，true 或 false，对应 Java 的 boolean
byte：8 位有符号整数，对应 Java 的 byte
i16：16 位有符号整数，对应 Java 的 short
i32：32 位有符号整数，对应 Java 的 int
i64：64 位有符号整数，对应 Java 的 long
double：64 位浮点数，对应 Java 的 double
string：utf-8编码的字符串，对应 Java 的 String

结构体类型：

struct：定义公共的对象，类似于 C 语言中的结构体定义，在 Java 中是一个 JavaBean

容器类型：

list：对应 Java 的 ArrayList
set：对应 Java 的 HashSet
map：对应 Java 的 HashMap

异常类型：

exception：对应 Java 的 Exception

服务类型：

service：对应服务的类

2.服务端编码基本步骤：

实现服务处理接口impl
创建TProcessor
创建TServerTransport
创建TProtocol
创建TServer
启动Server

3.客户端编码基本步骤：

创建Transport
创建TProtocol
基于TTransport和TProtocol创建 Client
调用Client的相应方法

4.数据传输协议

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

tips:客户端和服务端的协议要一致

[四]、实例演示

1. thrift生成代码

创建Thrift文件：G:\test\thrift\demoHello.thrift

1
namespace java com.micmiu.thrift.demo
 
   
2
 
 
   
3
service  HelloWorldService {
 
   
4
 string sayHello(1:string username) 
 
   
5
}

目录结构如下：

G:\test\thrift>tree /F 卷 other 的文件夹 PATH 列表卷序列号为 D238-BE47 G:. demoHello.thrift demouser.thrift thrift-0.8.0.exe 没有子文件夹

thrift-0.8.0.exe


thrift-0.8.0.exe -r -gen java ./demoHello.thrift

生成后的目录结构如下：

G:\test\thrift>tree /F 卷 other 的文件夹 PATH 列表卷序列号为 D238-BE47 G:. │ demoHello.thrift │ demouser.thrift │ thrift-0.8.0.exe │ └─gen-java └─com └─micmiu └─thrift └─demo HelloWorldService.java

将生成的HelloWorldService.java 文件copy到自己测试的工程中，我的工程是用maven构建的，故在pom.xml中增加如下内容：

1
 <dependency> 
 
   
2
 <groupId>org.apache.thrift</groupId> 
 
   
3
 <artifactId>libthrift</artifactId> 
 
   
4
 <version>0.8.0</version> 
 
   
5
 </dependency> 
 
   
6
 <dependency> 
 
   
7
 <groupId>org.slf4j</groupId> 
 
   
8
 <artifactId>slf4j-log4j12</artifactId> 
 
   
9
 <version>1.5.8</version> 
 
   
10
 </dependency>

2. 实现接口Iface

java代码：HelloWorldImpl.java

1
 package com.micmiu.thrift.demo; 
 
   
2
 
 
   
3
 import org.apache.thrift.TException; 
 
   
4
 
 
   
5
/**

7
 * 
 
   
8
 * @author Michael 
 
   
9
 * 
 
   
10
 */ 
 
   
11
 public class HelloWorldImpl implements HelloWorldService.Iface { 
 
   
12
 
 
   
13
 public HelloWorldImpl() { 
 
   
14
 } 
 
   
15
 
 
   
16
 @Override 
 
   
17
 public String sayHello(String username) throws TException { 
 
   
18
 return "Hi," + username + " welcome to my blog www.micmiu.com"; 
 
   
19
 } 
 
   
20
 
 
   
21
}

3.TSimpleServer服务端

简单的单线程服务模型，一般用于测试。

编写服务端server代码：HelloServerDemo.java

1
 package com.micmiu.thrift.demo; 
 
   
2
 
 
   
3
 import org.apache.thrift.TProcessor; 
 
   
4
 import org.apache.thrift.protocol.TBinaryProtocol; 
 
   
5
 import org.apache.thrift.protocol.TCompactProtocol; 
 
   
6
 import org.apache.thrift.protocol.TJSONProtocol; 
 
   
7
 import org.apache.thrift.protocol.TSimpleJSONProtocol; 
 
   
8
 import org.apache.thrift.server.TServer; 
 
   
9
 import org.apache.thrift.server.TSimpleServer; 
 
   
10
 import org.apache.thrift.transport.TServerSocket; 
 
   
11
 
 
   
12
/**

16
 * 
 
   
17
 */ 
 
   
18
 public class HelloServerDemo { 
 
   
19
 public static final int SERVER_PORT = 8090; 
 
   
20
 
 
   
21
 public void startServer() { 
 
   
22
 try { 
 
   
23
 System.out.println("HelloWorld TSimpleServer start ...."); 
 
   
24
 
 
   
25
 TProcessor tprocessor = newHelloWorldService.Processor<HelloWorldService.Iface>( 
 
   
26
 new HelloWorldImpl()); 
 
   
27
 // HelloWorldService.Processor<HelloWorldService.Iface> tprocessor = 
 
   
28
 // new HelloWorldService.Processor<HelloWorldService.Iface>( 
 
   
29
 // new HelloWorldImpl()); 
 
   
30
 
 
   
31
 // 简单的单线程服务模型，一般用于测试 
 
   
32
 TServerSocket serverTransport = newTServerSocket(SERVER_PORT); 
 
   
33
 TServer.Args tArgs = new TServer.Args(serverTransport); 
 
   
34
 tArgs.processor(tprocessor); 
 
   
35
 tArgs.protocolFactory(new TBinaryProtocol.Factory()); 
 
   
36
 // tArgs.protocolFactory(new TCompactProtocol.Factory()); 
 
   
37
 // tArgs.protocolFactory(new TJSONProtocol.Factory()); 
 
   
38
 TServer server = new TSimpleServer(tArgs); 
 
   
39
 server.serve(); 
 
   
40
 
 
   
41
 } catch (Exception e) { 
 
   
42
 System.out.println("Server start error!!!"); 
 
   
43
 e.printStackTrace(); 
 
   
44
 } 
 
   
45
 } 
 
   
46
 
 
   
47
 /** 
 
   
48
 * @param args 
 
   
49
 */ 
 
   
50
 public static void main(String[] args) { 
 
   
51
 HelloServerDemo server = new HelloServerDemo(); 
 
   
52
 server.startServer(); 
 
   
53
 } 
 
   
54
 
 
   
55
}

编写客户端Client代码：HelloClientDemo.java

1
 package com.micmiu.thrift.demo; 
 
   
2
 
 
   
3
 import org.apache.thrift.TException; 
 
   
4
 import org.apache.thrift.protocol.TBinaryProtocol; 
 
   
5
 import org.apache.thrift.protocol.TCompactProtocol; 
 
   
6
 import org.apache.thrift.protocol.TJSONProtocol; 
 
   
7
 import org.apache.thrift.protocol.TProtocol; 
 
   
8
 import org.apache.thrift.transport.TSocket; 
 
   
9
 import org.apache.thrift.transport.TTransport; 
 
   
10
 import org.apache.thrift.transport.TTransportException; 
 
   
11
 
 
   
12
/**
 
   
13
 * blog http://www.micmiu.com 
 
   
14
 * 
 
   
15
 * @author Michael 
 
   
16
 * 
 
   
17
 */ 
 
   
18
 public class HelloClientDemo { 
 
   
19
 
 
   
20
 public static final String SERVER_IP = "localhost"; 
 
   
21
 public static final int SERVER_PORT = 8090; 
 
   
22
 public static final int TIMEOUT = 30000; 
 
   
23
 
 
   
24
 /** 
 
   
25
 * 
 
   
26
 * @param userName 
 
   
27
 */ 
 
   
28
 public void startClient(String userName) { 
 
   
29
 TTransport transport = null; 
 
   
30
 try { 
 
   
31
 transport = new TSocket(SERVER_IP, SERVER_PORT, TIMEOUT); 
 
   
32
 // 协议要和服务端一致 
 
   
33
 TProtocol protocol = new TBinaryProtocol(transport); 
 
   
34
 // TProtocol protocol = new TCompactProtocol(transport); 
 
   
35
 // TProtocol protocol = new TJSONProtocol(transport); 
 
   
36
 HelloWorldService.Client client = newHelloWorldService.Client( 
 
   
37
 protocol); 
 
   
38
 transport.open(); 
 
   
39
 String result = client.sayHello(userName); 
 
   
40
 System.out.println("Thrify client result =: " + result); 
 
   
41
 } catch (TTransportException e) { 
 
   
42
 e.printStackTrace(); 
 
   
43
 } catch (TException e) { 
 
   
44
 e.printStackTrace(); 
 
   
45
 } finally { 
 
   
46
 if (null != transport) { 
 
   
47
 transport.close(); 
 
   
48
 } 
 
   
49
 } 
 
   
50
 } 
 
   
51
 
 
   
52
 /** 
 
   
53
 * @param args 
 
   
54
 */ 
 
   
55
 public static void main(String[] args) { 
 
   
56
 HelloClientDemo client = new HelloClientDemo(); 
 
   
57
 client.startClient("Michael"); 
 
   
58
 
 
   
59
 } 
 
   
60
 
 
   
61
}

先运行服务端程序，日志如下：

HelloWorld TSimpleServer start ....

再运行客户端调用程序，日志如下：

Thrify client result =: Hi,Michael welcome to my blog www.micmiu.com

测试成功，和预期的返回信息一致。

4.TThreadPoolServer 服务模型

线程池服务模型，使用标准的阻塞式IO，预先创建一组线程处理请求。

编写服务端代码：HelloServerDemo.java

1
 package com.micmiu.thrift.demo; 
 
   
2
 
 
   
3
 import org.apache.thrift.TProcessor; 
 
   
4
 import org.apache.thrift.protocol.TBinaryProtocol; 
 
   
5
 import org.apache.thrift.server.TServer; 
 
   
6
 import org.apache.thrift.server.TThreadPoolServer; 
 
   
7
 import org.apache.thrift.transport.TServerSocket; 
 
   
8
 
 
   
9
/**
 
   
10

 * @author Michael 
 
   
13
 * 
 
   
14
 */ 
 
   
15
 public class HelloServerDemo { 
 
   
16
 public static final int SERVER_PORT = 8090; 
 
   
17
 
 
   
18
 public void startServer() { 
 
   
19
 try { 
 
   
20
 System.out.println("HelloWorld TThreadPoolServer start ...."); 
 
   
21
 
 
   
22
 TProcessor tprocessor = newHelloWorldService.Processor<HelloWorldService.Iface>( 
 
   
23
 new HelloWorldImpl()); 
 
   
24
 
 
   
25
 TServerSocket serverTransport = newTServerSocket(SERVER_PORT); 
 
   
26
 TThreadPoolServer.Args ttpsArgs = newTThreadPoolServer.Args( 
 
   
27
 serverTransport); 
 
   
28
 ttpsArgs.processor(tprocessor); 
 
   
29
 ttpsArgs.protocolFactory(new TBinaryProtocol.Factory()); 
 
   
30
 
 
   
31
 // 线程池服务模型，使用标准的阻塞式IO，预先创建一组线程处理请求。 
 
   
32
 TServer server = new TThreadPoolServer(ttpsArgs); 
 
   
33
 server.serve(); 
 
   
34
 
 
   
35
 } catch (Exception e) { 
 
   
36
 System.out.println("Server start error!!!"); 
 
   
37
 e.printStackTrace(); 
 
   
38
 } 
 
   
39
 } 
 
   
40
 
 
   
41
 /** 
 
   
42
 * @param args 
 
   
43
 */ 
 
   
44
 public static void main(String[] args) { 
 
   
45
 HelloServerDemo server = new HelloServerDemo(); 
 
   
46
 server.startServer(); 
 
   
47
 } 
 
   
48
 
 
   
49
}

客户端Client代码和之前的一样，只要数据传输的协议一致即可，客户端测试成功，结果如下：

Thrify client result =: Hi,Michael welcome to my blog www.micmiu.com

5.TNonblockingServer 服务模型

使用非阻塞式IO，服务端和客户端需要指定 TFramedTransport

编写服务端代码：HelloServerDemo.java

1
 package com.micmiu.thrift.demo; 
 
   
2
 
 
   
3
 import org.apache.thrift.TProcessor;

6
 import org.apache.thrift.server.TServer; 
 
   
7
 import org.apache.thrift.transport.TFramedTransport; 
 
   
8
 import org.apache.thrift.transport.TNonblockingServerSocket; 
 
   
9

16
 public class HelloServerDemo { 
 
   
17
 public static final int SERVER_PORT = 8090; 
 
   
18
 
 
   
19
 public void startServer() { 
 
   
20
 try { 
 
   
21
 System.out.println("HelloWorld TNonblockingServer start ...."); 
 
   
22
 
 
   
23
 TProcessor tprocessor = newHelloWorldService.Processor<HelloWorldService.Iface>( 
 
   
24
 new HelloWorldImpl()); 
 
   
25
 
 
   
26
 TNonblockingServerSocket tnbSocketTransport = newTNonblockingServerSocket( 
 
   
27
 SERVER_PORT); 
 
   
28
 TNonblockingServer.Args tnbArgs = newTNonblockingServer.Args( 
 
   
29
 tnbSocketTransport); 
 
   
30
 tnbArgs.processor(tprocessor); 
 
   
31
 tnbArgs.transportFactory(new TFramedTransport.Factory()); 
 
   
32
 tnbArgs.protocolFactory(new TCompactProtocol.Factory()); 
 
   
33
 
 
   
34
 // 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 
 
   
35
 TServer server = new TNonblockingServer(tnbArgs); 
 
   
36
 server.serve(); 
 
   
37
 
 
   
38
 } catch (Exception e) { 
 
   
39
 System.out.println("Server start error!!!"); 
 
   
40
 e.printStackTrace(); 
 
   
41
 } 
 
   
42
 } 
 
   
43
 
 
   
44
 /** 
 
   
45
 * @param args 
 
   
46
 */ 
 
   
47
 public static void main(String[] args) { 
 
   
48
 HelloServerDemo server = new HelloServerDemo(); 
 
   
49
 server.startServer(); 
 
   
50
 } 
 
   
51
 
 
   
52

 // 协议要和服务端一致 
 
   
33
 TProtocol protocol = new TCompactProtocol(transport); 
 
   
34

43
 } finally { 
 
   
44
 if (null != transport) { 
 
   
45
 transport.close();

 client.startClient("Michael"); 
 
   
56
 
 
   
57
 } 
 
   
58
 
 
   
59
}

客户端的测试成功，结果如下：

Thrify client result =: Hi,Michael welcome to my blog www.micmiu.com

客户端代码和上面 4 中的类似，只要注意传输协议一致以及指定传输方式为TFramedTransport。

先运行服务程序，再运行客户端程序，测试结果如下：

Client start .....
call method sayHello start ...
call method sayHello .... end
onComplete
AsynCall result =:Hi,Michael welcome to my blog www.micmiu.com
latch.await =:true
startClient end.
