[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

推荐值得一看的文章：

• http://jnb.ociweb.com/jnb/jnbJun2009.html
  
• http://wiki.apache.org/thrift
• http://thrift.apache.org/static/files/thrift-20070401.pdf

[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：

[html] view plain copy print?

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

<dependency>  <groupId>org.apache.thrift</groupId>  <artifactId>libthrift</artifactId>  <version>0.8.0</version></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 ,内容如下：

[java] view plain copy print?

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

namespace java com.micmiu.thrift.demoservice  HelloWorldService {  string sayHello(1:string username)}

目录结构如下：

[java] view plain copy print?

1. G:\test\thrift>tree /F  
2. 卷 other 的文件夹 PATH 列表  
3. 卷序列号为 D238-BE47  
4. G:.  
5.     demoHello.thrift  
6.     demouser.thrift  
7.     thrift-0.8.0.exe  
8.   
9. 没有子文件夹  

G:\test\thrift>tree /F卷 other 的文件夹 PATH 列表卷序列号为 D238-BE47G:.    demoHello.thrift    demouser.thrift    thrift-0.8.0.exe没有子文件夹

thrift-0.8.0.exe 是官网提供的windows下编译工具，运用这个工具生成相关代码：

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

生成后的目录结构如下：

[java] view plain copy print?

1. G:\test\thrift>tree /F  
2. 卷 other 的文件夹 PATH 列表  
3. 卷序列号为 D238-BE47  
4. G:.  
5. │  demoHello.thrift  
6. │  demouser.thrift  
7. │  thrift-0.8.0.exe  
8. │  
9. └─gen-java  
10.     └─com  
11.         └─micmiu  
12.             └─thrift  
13.                 └─demo  
14.                         HelloWorldService.java  

G:\test\thrift>tree /F卷 other 的文件夹 PATH 列表卷序列号为 D238-BE47G:.│  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：

[html] view plain copy print?

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>  

<dependency><groupId>org.apache.thrift</groupId><artifactId>libthrift</artifactId><version>0.8.0</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.5.8</version></dependency>

2. 实现接口Iface

java代码：HelloWorldImpl.java

[java] view plain copy print?

1. package com.micmiu.thrift.demo;  
2.   
3. import org.apache.thrift.TException;  
4.   
5. /** 
6.  * blog http://www.micmiu.com 
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. }  

package com.micmiu.thrift.demo;import org.apache.thrift.TException;/** * blog http://www.micmiu.com * * @author Michael * */public class HelloWorldImpl implements HelloWorldService.Iface {public HelloWorldImpl() {}@Overridepublic String sayHello(String username) throws TException {return "Hi," + username + " welcome to my blog www.micmiu.com";}}

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.     /**

21.     public static final int SERVER_PORT = 8090;  
22.     public static final int TIMEOUT = 30000;  
23.   
24.     /**

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 = new HelloWorldService.Client(  
37.                     protocol);  
38.             transport.open();  
39.             String result = client.sayHello(userName);  
40.             System.out.println("Thrify client result =: " + result);

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

[java] view plain copy print?

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.  * blog http://www.micmiu.com 
11.  * 
12.  * @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 = new HelloWorldService.Processor<HelloWorldService.Iface>(  
23.                     new HelloWorldImpl());  
24.   
25.              TServerSocket serverTransport = new TServerSocket(SERVER_PORT);  
26.              TThreadPoolServer.Args ttpsArgs = new TThreadPoolServer.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. }  

package com.micmiu.thrift.demo;import org.apache.thrift.TProcessor;import org.apache.thrift.protocol.TBinaryProtocol;import org.apache.thrift.server.TServer;import org.apache.thrift.server.TThreadPoolServer;import org.apache.thrift.transport.TServerSocket;/** * blog http://www.micmiu.com * * @author Michael * */public class HelloServerDemo {public static final int SERVER_PORT = 8090;public void startServer() {try {System.out.println("HelloWorld TThreadPoolServer start ....");TProcessor tprocessor = new HelloWorldService.Processor<HelloWorldService.Iface>(new HelloWorldImpl()); TServerSocket serverTransport = new TServerSocket(SERVER_PORT); TThreadPoolServer.Args ttpsArgs = new TThreadPoolServer.Args( serverTransport); ttpsArgs.processor(tprocessor); ttpsArgs.protocolFactory(new TBinaryProtocol.Factory());// 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。 TServer server = new TThreadPoolServer(ttpsArgs); server.serve();} catch (Exception e) {System.out.println("Server start error!!!");e.printStackTrace();}}/** * @param args */public static void main(String[] args) {HelloServerDemo server = new HelloServerDemo();server.startServer();}}

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 数据传输的方式。

编写服务端代码：HelloServerDemo.java

6.THsHaServer服务模型

半同步半异步的服务端模型，需要指定为： TFramedTransport 数据传输的方式。

编写服务端代码：HelloServerDemo.java

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.
