Thrift学习笔记

一：thrift介绍

　　Thrift是facebook开发的用来处理各不同系统之间数据通讯的rpc服务框架，后来成为apche的开源项目。thrift支持多种程序语言，包括Java,Python,Ruby,JavaScript,Node.js,Go,C,C++,C#,Erlang,Delphi,Perl,Php,SmallTalk,OCaml,Haxe,Haskell,D语言。Thrift采用IDL(Interface Defination Language)描述性语言来定义数据结构和接口。Thrift模型如下所示：

图 thrift模型图

二 thrift数据传输协议

TBinaryProtocol 二进制传输协议

TCompactProtocol 使用VLQ编码进行压缩的数据传输协议

TJSONProtocol JSON格式的数据传输协议

TSimpleJSONProtocol 简单的JSON格式数据传输协议

TDebugProtocol 调试时使用的文本传输协议

三 thrift传输层

TFramedTransport 按块的大小进行传输

TFileTransport 按照文件的方式进行传输

TMemoryTransport 使用内存IO方式进行传输

TZlibTransport 执行zlib压缩方式传输

四 thrift服务器端

TSimpleServer 简单的单线程标准阻塞式服务器

TThreadPoolServer 多线程阻塞式服务器

TNonblockingServer 多线程非阻塞式服务器

THsHaServer 半同步半异步服务器

其实传输层的传输只有阻塞和非阻塞，再加上具体的工作方式单线程多线程

五 thrift客户端

TClient 简单单线程阻塞式客户端

TAsynClient 异步客户端(多线程)

六 thrift开发步骤

1服务器端

实现服务处理接口impl

创建TProcessor

创建TServerTransport(TServerSocket) 创建阻塞通信的还是非阻塞通信

创建TProtocol 数据传输协议

创建TServer 服务器类型单工(单线程) 双工(多线程) 半单工半双工(多线程)

启动Server

2客户端

创建Transport(TSocket) 创建阻塞通信(客户端只有阻塞)

创建TProtocol 数据传输协议

基于TTransport和TProtocol创建Client

调用Client的相应方法

七 thrift数据类型

1基本类型

bool：布尔值，true 或 false

byte：8 位有符号整数

i16：16 位有符号整数

i32：32 位有符号整数

i64：64 位有符号整数

double：64 位浮点数

string：utf-8编码的字符串

2结构体类型

struct：定义公共的对象

enum: 枚举类型

3容器类型

list：对应 Java 的 ArrayList

set：对应 Java 的 HashSet

map：对应 Java 的 HashMap

4异常类型

exception：对应 Java 的 Exception

5服务类型

service：对应服务的类提供接口

八 thrift例子

enum 类型

struct Student{
     1: required i32 id
     2: required string username
     3: required string password
     4: requried string number
     5: optional double age
}

struct 类型

struct School{
     1: required i32 id
     2: required string name
     3: required set<Student> students
     4: required list<Student> rank
     5: required map<string, string> number_name
}

service 类型

service ThriftMysqlService{
     void addUser(1:Student user)
     list<Student> queryAllUser()
     Student queryOneUser(1:i32 id)
     map<string, string> queryOneArticle(1:i32 id)
}

具体代码

thrift.thrift 定义数据类型和接口的文件

namespace java org.seava.thrift_example.thrift

struct User{
    1: required i32 userId
    2: required string username
    3: required string password
}

service ThriftService{
    void addUser(1:User user)
    User queryUser(1:i32 id)
    list<User> queryUserList()
    map<string, string> queryUserNamePass()
    map<i32, User> queryUserMap()
}

到apache的官网下载thrift.exe程序，下载地址 http://thrift.apache.org/ ，下下来通过cmd命令窗口去运行如下命令

thrift  -gen java xxx.thrift
