## 场景 ##

### Thrift ###

Thrift最初由Facebook研发，主要用于各个服务之间的RPC通信，支持跨语言，常用的语言比如C++, Java, Python,PHP, Ruby, Erlang，Perl，Haskell, C\#, Cocoa, JavaScript, Node.js, Smalltalk, and OCaml都支持。

Thrift是一个典型的CS(客户端/服务端)结构，客户端和服务端可以使用不同的语言开发。既然客户端和服务端能使用不同的语言开发，那么一定就要有一种中间语言来关联客户端和服务端的语言，这种语言就是IDL (Interface Description Language)。

### RPC ###

RPC, 远程过程调用,直观说法就是A通过网络调用B的过程方法。

简单的说，RPC就是从一台机器（客户端）上通过参数传递的方式调用另一台机器（服务器）上的一个函数或方法（可以统称为服务）并得到返回的结果。

RPC 会隐藏底层的通讯细节（不需要直接处理Socket通讯或Http通讯） RPC 是一个请求响应模型。

客户端发起请求，服务器返回响应（类似于Http的工作方式） RPC 在使用形式上像调用本地函数（或方法）一样去调用远程的函数（或方法）。

## 实现 ##

### Thrift数据类型 ###

Thrift不支持无符号类型，因为很多编程语言不存在无符号类型，比如Java。

byte：有符号字节  
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：字符串类型

### Thrift容器类型 ###

list:一系列由T类型的数据组成的有序列表，元素可以重复

set:一系列由T类型的数据组成的无序集合，元素不可重复

map:一个字典结构，key为K类型，value为V类型，相当于Java中的HashMap

### Thrift工作原理 ###

如何实现多语言之间的通信？

数据传输使用socket(多种语言均支持)，数据再以特定的格式(String等)发送，接收方语言进行解析。

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结构体 ###

就像C语言一样，Thrift支持struct类型，目的就是将  
一些数据聚合在一起，方便传输管理。struct的定义  
形式如下:

struct People{
    1:string name;
    2: i32 age;
    3: string gender;
    }

### Thrift枚举 ###

枚举的定义形式和Java的Enum定义类似

enum Gender{
    MALE,
    FEMALE
    }

### Thrift异常 ###

Thrift支持自定义exception，规则与struct一样

exception RequestException{
    1:i32 code;
    2: string reason:
    }

### Thrift服务 ###

Thrift定义服务相当于Java中创建Interface一样，创建的service经过代码生成命令之后就会生成客户端和服务端的框架代码。定义形式如下:、

service HelloWordService {
    // service中定义的函数，相当于Java interface中定义的方法
    string doAction(1:string name，2: i32 age);
    }

### Thrift类型定义 ###

Thrift支持类似C++一样的typedef定义:

typedef i32 int
    typedef i64 long

定义别名

### Thrift常量 ###

thrift也支持常量定义，使用const关键字:

const i32 MAX_RETRIES_TIME=10
    const string MY_WEBSITE=
    "https://blog.csdn.net/BADAO_LIUMANG_QIZHI'

### 命名空间 ###

Thrift的命名空间相当于Java中的package的意思，主要目的是组织代码。thrift使用关键字namespace 定义命名空间:

namespace java com.bdao.thrift

格式是: namespace 语言名 路径

### 文件包含 ###

Thrift也支持文件包含，相当于C/C++中的include,Java中的import。使用关键字include定义:

include "global.thrift"

### 注释 ###

Thrift注释方式支持shell风格的注释，支持C/C++风格的注释，即\#和//开头的语句都当做注释，/\*\*/包裹的语句也是注释。

### 可选与必选 ###

Thrift提供两个关键字required, optional，分别用于表示对应的字段是必填的还是可选的

struct People{
      1:required string name;
      2:optional i32 age;
    }

### Thrift传输 ###

thrift通过一个中间语言IDL(接口定义语言)来定义RPC的数据类型和接口,这些内容写在以.thrift结尾的文件中,然后通过特殊的编译器来生成不同语言的代码

,以满足不同需要的开发者,比如java开发者,就可以生成java代码,c++开发者可以生成c++代码,生成的代码中不但包含目标语言的接口定义,方法,数据类型,

还包含有RPC协议层和传输层的实现代码。

图中，TProtocol（协议层），定义数据传输格式，例如：

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；  
TDebugProtocol：使用易懂的可读的文本格式，以便于debug  
TTransport（传输层），定义数据传输方式，可以为TCP/IP传输，内存共享或者文件共享等）被用作运行时库。

TSocket：阻塞式socker；  
TFramedTransport：以frame为单位进行传输，非阻塞式服务中使用；  
TFileTransport：以文件形式进行传输；  
TMemoryTransport：将内存用于I/O，java实现时内部实际使用了简单的ByteArrayOutputStream；  
TZlibTransport：使用zlib进行压缩， 与其他传输方式联合使用，当前无java实现；

Thrift支持的服务模型

TSimpleServer：简单的单线程服务模型，常用于测试；  
TThreadPoolServer：多线程服务模型，使用标准的阻塞式IO；  
TNonblockingServer：多线程服务模型，使用非阻塞式IO（需使用TFramedTransport数据传输方式）；

###  ###

### Java中使用Thrift实现RPC示例 ###

首先需要下载并配置thrift的编译器，下载地址

[http://thrift.apache.org/download][http_thrift.apache.org_download]

这里下载Windows版本为例

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 1][]

下载thrift的exe文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

将其下载到磁盘中某目录，然后在环境变量的的系统变量的Path中将exe所在的路径添加。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

这样就能在任何地方使用thrift-0.13.0.exe了，为了使用命令方便，将此exe命名为thrift.exe

然后打开cmd ，输入

thrift -version

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 4][]

出现如上则配置成功。

这里使用Gradle作为依赖管理，当然也可以使用Maven，只是管理方式不同而已。

Gradle在Windows下的下载安装与配置以及在IDEA中配置以及修改jar包位置：

[https://blog.csdn.net/BADAO\_LIUMANG\_QIZHI/article/details/108578033][https_blog.csdn.net_BADAO_LIUMANG_QIZHI_article_details_108578033]

参照上面在IDEA中进行搭建Gradle项目

然后在build.gradle中引入thrift的相关依赖，在Maven中央仓库中搜搜thrift

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 5][]

选择与编译器对应的版本这里是0.13.0

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 6][]

选择gradle的依赖配置进行复制

然后复制到build.gradle中

dependencies {
        compile (
                [group:'org.apache.thrift', name: 'libthrift', version: '0.13.0']
        )
    }

因为设置了自动导入，所以会在项目中自动引入thrift相关的依赖

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 7][]

然后在src下新建thrift目录，在此目录下新建MyData.thrift文件

namespace java thrift.generated
    
    typedef i16 short
    typedef i32 int
    typedef i64 long
    typedef bool boolean
    typedef string String
    
    struct Person {
        1:optional String username,
        2:optional int age,
        3:optional boolean married
    }
    
    exception DataException {
        1:optional String message,
        2:optional String callback,
        3:optional String date
    }
    
    service PersonService {
        Person getPersonByUsername(1:required String username) throws (1:DataException dataException),
        void savePerson(1:required Person person) throws(1:DataException dataException)
    }

然后在IDEA中新建Terminal

thrift --gen java src/thrift/MyData.thrift

后面跟的目录就是thrift文件所在的路径

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 8][]

此时会在项目的根目录下生成代码，然后在src/main/java/com.badao下新建一个目录Thrift，然后将上面生成的代码复制到此路径下。

此时代码就已经生成好，

在此目录下新建PersonServiceImpl并实现生成的PersonService接口

package com.badao.Thrift;
    
    import org.apache.thrift.TException;
    
    public class PersonServiceImpl implements PersonService.Iface {
        @Override
        public Person getPersonByUsername(String username) throws DataException, TException {
            System.out.println("getPersonByUsername被调用并收到参数:" + username);
            Person person = new Person();
            person.setUsername("公众号：霸道的程序猿");
            person.setAge(100);
            person.setMarried(true);
    
            return person;
        }
    
        @Override
        public void savePerson(Person person) throws DataException, TException {
            System.out.println("savePerson方法被调用，接收到的参数为:");
            System.out.println(person.getUsername());
            System.out.println(person.getAge());
            System.out.println(person.isMarried());
        }
    }

并且实现其两个方法，在根据用户名获取Person实体的方法中

输出接收到的username参数并将一个Person对象返回。

在保存Person的方法中将接收到的Person对象进行输出。

然后在此目录下新建服务端类ThriftServer

package com.badao.Thrift;
    
    import org.apache.thrift.TProcessorFactory;
    import org.apache.thrift.protocol.TCompactProtocol;
    import org.apache.thrift.server.THsHaServer;
    import org.apache.thrift.server.TServer;
    import org.apache.thrift.transport.TFramedTransport;
    import org.apache.thrift.transport.TNonblockingServerSocket;
    
    
    public class ThriftServer {
        public static void main(String[] args) throws Exception
        {
            //设置服务器端口  TNonblockingServerSocket-非堵塞服务模型
            TNonblockingServerSocket serverSocket = new TNonblockingServerSocket(8899);
            //参数设置
            THsHaServer.Args arg = new THsHaServer.Args(serverSocket).minWorkerThreads(2).maxWorkerThreads(4);
            //处理器
            PersonService.Processor<PersonServiceImpl> processor = new PersonService.Processor<>(new PersonServiceImpl());
            arg.protocolFactory(new TCompactProtocol.Factory());
            arg.transportFactory(new TFramedTransport.Factory());
            arg.processorFactory(new TProcessorFactory(processor));
    
            TServer server = new THsHaServer(arg);
            System.out.println("Thrift 服务端启动成功");
            server.serve();
        }
    
    
    }

绑定端口并启动服务端。

然后在此路径下新建客户端ThriftClient

package com.badao.Thrift;
    
    import org.apache.thrift.protocol.TCompactProtocol;
    import org.apache.thrift.protocol.TProtocol;
    import org.apache.thrift.transport.TFramedTransport;
    import org.apache.thrift.transport.TSocket;
    import org.apache.thrift.transport.TTransport;
    
    public class ThriftClient {
        public static void main(String[] args) {
            TTransport transport = new TFramedTransport(new TSocket("localhost", 8899), 600);
            TProtocol protocol = new TCompactProtocol(transport);
            PersonService.Client client = new PersonService.Client(protocol);
    
            try {
                transport.open();
    
                Person person = client.getPersonByUsername("公众号:霸道的程序猿");
                System.out.println(person.getUsername());
                System.out.println(person.getAge());
                System.out.println(person.isMarried());
    
                System.out.println("------------------------");
    
                Person person1 = new Person();
                person1.setUsername("公众号:霸道的程序猿");
                person1.setAge(50);
                person1.setMarried(true);
    
                client.savePerson(person1);
    
            }catch (Exception ex){
                throw new RuntimeException(ex.getMessage(),ex);
            }finally {
                transport.close();
            }
        }
    }

与服务端建立连接并调用服务端的两个方法，然后运行服务端

然后再运行客户端

此时客户端已经调用getPersonByUsername并输出数据并且调用了服务端的savePerson方法
