Thrift交流（一）簡單的Thrift

轉載自 CSDN Arjick

Thrift是一個可伸縮的跨語言的服務開發框架，是facebook開發的一個跨語言通信平臺。爲各種語言提供快捷的rpc服務。現階段已經支持C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk, and OCaml等語言。在近來的工作中，重新學習Thrift通信的內容，和大家做個簡單的交流。

1）安裝Thrift環境

Thrift的環境的安裝並不複雜，我們現在以最簡單的windows環境做個案例。

首先在官方網站下載最新的thrift exe文件，http://thrift.apache.org/download/

然後把exe文件改名爲thrift.exe,放在了windows的目錄下，如圖所示：

接着配置thrift環境變量：

測試Thrift運行環境：

2）編寫Thrift文件

thrift文件如下

namespace java thrift  // defines the namespace

typedef i32 int  //typedefs to get convenient names for your types

service ThriftService {
    int add(1:int a,2:int b),
}

通過命令行執行Thrift文件，並生成

3）建立Thrift工程

首先建立maven工程，把如下內容加到pom.xml

<dependency>
            <groupId>org.apache.thrift</groupId>
            <artifactId>libthrift</artifactId>
            <version>0.9.0</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.5</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-simple</artifactId>
            <version>1.7.5</version>
        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>1.7.5</version>
        </dependency>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>

編寫ThriftService的實現類：

代碼如下：

package thrift;

import org.apache.thrift.TException;

public class ThriftServiceImpl implements Iface {

    @Override
    public int add(int a, int b) throws TException {
        return a + b;
    }

}

4）編寫服務器及測試

package com.duowan.yy.thriftTest;

import org.apache.thrift.TProcessor;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TBinaryProtocol.Factory;
import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TSimpleServer;
import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TTransportException;

import thrift.ThriftService;
import thrift.ThriftServiceImpl;

public class ThriftServer {
    public static void main(String[] args) {
        try {
            TServerSocket serverTransport = new TServerSocket(7911);

            Factory proFactory = new TBinaryProtocol.Factory();

            TProcessor processor = new ThriftService.Processor<ThriftService.Iface>(
                    new ThriftServiceImpl());
            TServer.Args tArgs = new TServer.Args(serverTransport);
            tArgs.processor(processor);
            tArgs.protocolFactory(proFactory);

            TServer server = new TSimpleServer(tArgs);
            System.out.println("Start server on port 7911....");
            server.serve();
        } catch (TTransportException e) {
            e.printStackTrace();
        }
    }
}

測試啓動：

編寫測試類：

package com.duowan.yy.thriftTest;

import org.apache.thrift.TException;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;
import org.apache.thrift.transport.TTransportException;

import thrift.ThriftService;


public class Test {

    /**
     * @param args
     */
    public static void main(String[] args) {
        try {
            TTransport transport = new TSocket("localhost", 7911);
            transport.open();
            TProtocol protocol = new TBinaryProtocol(transport);
            ThriftService.Client client = new ThriftService.Client(protocol);
            System.out.println(client.add(77, 5));
            transport.close();

        } catch (TTransportException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (TException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

  效果如下：

簡單的Thrift之旅已經完成了，希望大家玩的開心。
