thrift 交互ruby 和java

thrift在apache中主页http://thrift.apache.org/

Thrift是一个可以提供跨语言开发的框架，它允许你在一个配置文件中定义数据类型和服务接口，把这个文件作为输入，编译器产生的代码将要被用来建立RPC客户端和服务端的跨语言的无缝连接。
thrift0.5的下载地址
http://www.apache.org/dyn/closer.cgi?path=/incubator/thrift/0.5.0-incubating/thrift-0.5.0.tar.gz
下载之后编译安装

开始交互之旅
thrift的数据类型：

1 基本数据类型有

Java代码

bool: A boolean value (true orfalse)
byte: An 8-bit signed integer
i16: A 16-bit signed integer
i32: A 32-bit signed integer
i64: A 64-bit signed integer
double: A 64-bit floating point number
string: A text string encoded using UTF-8 encoding

bool: A boolean value (true or false)byte: An 8-bit signed integeri16: A 16-bit signed integeri32: A 32-bit signed integeri64: A 64-bit signed integerdouble: A 64-bit floating point numberstring: A text string encoded using UTF-8 encoding

2 特殊类型

Java代码

binary: a sequence of unencoded bytes

binary: a sequence of unencoded bytes

3 结构体
4 容器

Java代码

list<type>: An ordered list of elements. Translates to an STL vector, Java ArrayList,native arrays in scripting languages, etc.
set<type>: An unordered set of unique elements. Translates to an STL set, Java HashSet, set in Python, etc. This type is not supported in PHP! Use lists instead.
map<type1,type2>: A map of strictly unique keys to values. Translates to an STL map, Java HashMap, PHP associative array, Python/Ruby dictionary, etc.

一、新建thrift文件 user.thrift

Xml代码

struct User {
1: string id,
2: string name,
}
service UserStorage {
void set_user(1: User user),
User get_user(1: string id)
}

struct User {  1: string id,  2: string name,}service UserStorage {  void set_user(1: User user),  User get_user(1: string id)}

在此目录下运行thrift命令，生成相应的java文件和ruby文件
生成java相关文件的命令：

Java代码

thrift -r -gen java user.thrift

thrift -r -gen java user.thrift

生成ruby相关文件的命令：

Java代码

thrift -r -gen rb user.thrift

thrift -r -gen rb user.thrift

执行命令之后，会发现此目录下面产生了两个文件夹gen-java 和 gen-rb
gen-java下面有两个文件 User.java(对struct User的实现) 和 UserStorage.java(对service UserStorage的实现)
gen-rb 下面有三个文件 user_storage.rb(对service UserStorage的实现) ， user_types.rb ，user_constants.rb(后面两个文件对struct User的实现，后者只有一句话require 'user_types')

二、用java做服务端
新建一个java工程，将两个java文件引入，下面开始实现服务
首先要实现那两个自定一个接口方法

Java代码

public class UserServiceHandlerimplements UserStorage.Iface {
public void set_user(User user)throws TException {
System.out.println(user.name + " " + user.id);
}
public User get_user(String id)throws TException {
// 没有逻辑意义，纯粹是为了返回一个user
User user = new User();
user.setId(id);
user.setName("user_one");
return user;
}
}

public class UserServiceHandler  implements UserStorage.Iface {  public void set_user(User user) throws TException {    System.out.println(user.name + " " + user.id);  }  public User get_user(String id) throws TException {    // 没有逻辑意义，纯粹是为了返回一个user    User user = new User();    user.setId(id);    user.setName("user_one");    return user;  }  }

启动java这边的服务

Java代码

public staticvoid main(String[] args) {
try {
UserServiceHandler handler = new UserServiceHandler();
UserStorage.Processor processor = new UserStorage.Processor(handler);
TServerTransport serverTransport = new TServerSocket(9090);
TServer server = new TSimpleServer(processor, serverTransport);
// Use this for a multithreaded server
// server = new TThreadPoolServer(processor, serverTransport);
System.out.println("Starting the server...");
server.serve();
} catch (TTransportException tTransportException) {
}
}

  public static void main(String[] args) {    try {      UserServiceHandler handler = new UserServiceHandler();      UserStorage.Processor processor = new UserStorage.Processor(handler);      TServerTransport serverTransport = new TServerSocket(9090);      TServer server = new TSimpleServer(processor, serverTransport);      // Use this for a multithreaded server      // server = new TThreadPoolServer(processor, serverTransport);      System.out.println("Starting the server...");      server.serve();    } catch (TTransportException tTransportException) {    }  }

三 ruby客户端

Ruby代码

require 'thrift'
require 'user_constants'
require 'user_storage'
transport = Thrift::BufferedTransport.new(Thrift::Socket.new('localhost', 5555))
protocol = Thrift::BinaryProtocol.new(transport)
client = UserStorage::Client.new(protocol)
transport.open()
user = client.get_user('123')
p user

require 'thrift'require 'user_constants'require 'user_storage'transport = Thrift::BufferedTransport.new(Thrift::Socket.new('localhost', 5555))protocol = Thrift::BinaryProtocol.new(transport)client = UserStorage::Client.new(protocol)transport.open()user = client.get_user('123')p user

运行ruby的客户端，即可输出接口所设置的user
属性如下
id 123
name user_one
