一、About thrift
thrift是一种可伸缩的跨语言服务的发展软件框架。它结合了功能强大的软件堆栈的代码生成引擎,以建设服务,工作效率和无缝地与C +
+,C#,Java,Python和PHP和Ruby结合。thrift是facebook开发的,我们现在把它作为开源软件使用。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(来自百度百
科)。
>>>最初由facebook开发用做系统内个语言之间的RPC通信 。
>>>2007年由facebook贡献到apache基金 ,现在是apache下的opensource之一 。
>>>支持多种语言之间的RPC方式的通信:php语言client可以构造一个对象,调用相应的服务方法来调用java语言的服务 ,跨越语言的C/S rpc 调用 。
二、什么是thrift,怎么工作?
java rmi的例子,代码见附件,建立一个java rmi的流程 :
>>>定义一个服务调用接口 。
>>>server端:接口实现---impl的实例---注册该服务实现(端口)---启动服务。
>>>client端:通过ip、端口、服务名,得到服务,通过接口来调用 。
>>>rmi数据传输方式:java对象序列化 。
Thrift 服务
>>>例同rmi ,需要定义通信接口、实现、注册服务、绑定端口……
>>>如何多种语言之间通信 ?
>>>数据传输走socket(多种语言均支持),数据再以特定的格式(String ),发送,接收方语言解析 。
Object ---> String ---> Object 。
问题:编码、解析完全需要自己做 ,复杂的数据结构会编码困难 .
Thrift 服务 :thrift的中间编码层
>>>java Object ---> Thrift Object ---> php Object
>>> 定义thrift的文件 ,由thrift文件(IDL)生成 双方语言的接口、model ,在生成的model以及接口中会有解码编码的代码 。
>>>thrift 文件例子

五、Thrift 协议栈 以及各层的使用(java 为例)
1、model interface
服务的调用接口以及接口参数model、返回值model
2、Tprotocol 协议层
将数据(model)编码 、解码 。
3、Ttramsport 传输层
编码后的数据传输(简单socket、http)
5、Tserver
服务的Tserver类型,实现了几种rpc调用(单线程、多线程、非阻塞IO)
六、与protocolbuffer的区别
http://liuchangit.com/development/346.html
http://stackoverflow.com/questions/69316/biggest-differences-of-thrift-vs-protocol-buffers
区别:
1、Another important difference are the languages supported by
default. protobuf: Java, C++, Python Thrift: Java, C++, Python,
PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk, Ocaml
支持语言不同,thrift支持着更多的语言 。
2、Thrift supports ‘exceptions 。
thrift支持服务的异常 。
3、Protocol Buffers much easier to read 。Protobuf API looks cleaner,
though the generated classes are all packed as an inner classes which is
not so nice.
Protocol Buffers 在文档方面比thrift丰富,而且比thrift简单 。
4、Protobuf serialized objects are about 30% smaller then Thrift.
Protocol Buffers在序列化/反序列化、传输上性能更优 。
5、RPC is another key difference. Thrift generates code to implement
RPC clients and servers wheres Protocol Buffers seems mostly designed as
a data-interchange format alone.
thrift提供了一套完整的rpc服务实现(多线程socket、非阻塞的socket....)
6、And according to the wiki the Thrift runtime doesn't run on Windows.
thrift 对有些语言在windows上不支持:C++ .....
