一、About? thrift???
???????? thrift是一種可伸縮的跨語言服務的發展軟件框架。它結合了功能強大的軟件堆棧的代碼生成引擎，以建設服務，工作效率和無縫地與C + +，C#，Java，Python和PHP和Ruby結合。thrift是facebook開發的，我們現在把它作為開源軟件使用。thrift允許你定義一個簡單的定義文件中的數據類型和服務接口。以作為輸入文件，編譯器生成代碼用來方便地生成RPC客戶端和服務器通信的無縫跨編程語言（來自百度百科）。????
? >>>最初由facebook開發用做系統內個語言之間的RPC通信。?
? >>>2007年由facebook貢獻到apache基金，現在是apache下的opensource之一。?
? >>>支持多種語言之間的RPC方式的通信：php語言client可以構造一個對象，調用相應的服務方法來調用java語言的服務，跨越語言的C/S?? rpc? 調用。?

二、什么是thrift，怎么工作？ ?

java? rmi的例子，代碼見附件，建立一個java rmi的流程? ：?
? >>>定義一個服務調用接口。?
? >>>server端：接口實現---impl的實例---注冊該服務實現（端口）---啟動服務。?
? >>>client端：通過ip、端口、服務名，得到服務，通過接口來調用。?
? >>>rmi數據傳輸方式：java對象序列化。?

Thrift? 服務??
? >>>例同rmi ，需要定義通信接口、實現、注冊服務、綁定端口……?
? >>>如何多種語言之間通信? ？?
? >>>數據傳輸走socket（多種語言均支持），數據再以特定的格式（String ），發送，接收方語言解析?? 。?
??????? Object --->? String --->? Object? 。?

??? 問題：編碼、解析完全需要自己做，復雜的數據結構會編碼困難 .?

Thrift? 服務：thrift的中間編碼層?
? >>>java? Object ---> Thrift? Object ---> php? Object???
? >>> 定義thrift的文件，由thrift文件（IDL）生成雙方語言的接口、model ，在生成的model以及接口中會有解碼編碼的代碼。?

五、Thrift 協議棧以及各層的使用（java 為例） ?
thrift的使用介紹 ?
1、model?? interface?
?????? 服務的調用接口以及接口參數model、返回值model?
2、Tprotocol??? 協議層?
???????? 將數據（model）編碼、解碼。?
3、Ttramsport 傳輸層?
??????? 編碼后的數據傳輸（簡單socket、http）?
5、Tserver?
??????? 服務的Tserver類型，實現了幾種rpc調用（單線程、多線程、非阻塞IO）?

六、與protocolbuffer的區別 ?
http://liuchangit.com/development/346.html?
????????????
http://stackoverflow.com/questions/69316/biggest-differences-of-thrift-vs-protocol-buffers?

區別：?
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?
支持語言不同，thrift支持著更多的語言。?
2、Thrift supports ‘exceptions 。?
?? thrift支持服務的異常。?
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 在文檔方面比thrift豐富，而且比thrift簡單。?
4、Protobuf serialized objects are about 30% smaller then Thrift.?
?? Protocol Buffers在序列化/反序列化、傳輸上性能更優。?
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服務實現（多線程socket、非阻塞的socket....）?
6、And according to the wiki the Thrift runtime doesn't run on Windows.?
?? thrift 對有些語言在windows上不支持：C++?? .....?
