thrift的使用
1.下载源代码(tips:到官网上有提升下载那个最快的)
wget http://mirrors.cnnic.cn/apache/thrift/0.9.2/thrift-0.9.2.tar.gz
tar -xf thrift-0.9.2.tar.gz
cd thrift-0.9.2
2.安装boost库（tips:centos下使用yum，Ubuntu用apt）
sudo yum install libboost-dev libboost-dbg libboost-doc bcp libboost-*
./configure --with-cpp --with-boost --without-python --without-csharp --with-java --without-erlang --without-perl --without-php --without-php_extension --without-ruby --without-haskell --without-go
make
sudo make install
测试
看上去好像很简单，但是却会出现些奇怪的问题，例如：
error： Bison version 2.5 or higher must be installed on the system!
Bison版本低了
wget http://ftp.gnu.org/gnu/bison/bison-2.5.tar.gz tar -zxvf bison-2.5.tar.gz cd bison-2.5 ./configure make && make install
在上面第二步，可能回报错说lua未找到这样的错误，你可以在./configure后面加上参数，如：
./configure –with-lua=no
configure阶段，不要lua的话可以安装其他的，也可以指定安装一些语言的模块，如下就行：
./configure –with-python –with-php
直接输入thrift命令，看是否有用法提示
写 Thrift定义文件（.thrift file）
如果你之前有接触过这个东西的话，写定义文件非常的简单。但这里可以参考官方的教程快速开始。
示例定义文件（demoHello.thrift）
namespace java com.micmiu.thrift.demo service HelloWorldService { string sayHello(1:string username) }
编译Thrift定义文件
下面的命令编译.thrift文件
thrift --gen <language> <Thrift filename>
于我而已命令如下：
thrift --gen java demoHello.thrift
在执行完代码后，在gen-java目录下你会发现构建RPC服务器和客户端有用的源代码。在我的例子中我将创建一个叫做HelloWorldService.java的java文件对于我的例子来讲，命令是：
建立maven工程：

测试：
先运行服务端程序，日志如下：
HelloWorld TSimpleServer start ....
再运行客户端调用程序，日志如下：
Thrify client result =: Hi,Michael welcome to my blog www.micmiu.com
测试成功，和预期的返回信息一致。
TThreadPoolServer 服务模型
线程池服务模型，使用标准的阻塞式IO，预先创建一组线程处理请求。
HelloServerDemo2
package ThriftTest.ThriftTest; import org.apache.thrift.TProcessor; import org.apache.thrift.protocol.TBinaryProtocol; import org.apache.thrift.server.TServer; import org.apache.thrift.server.TThreadPoolServer; import org.apache.thrift.transport.TServerSocket; /** * blog http://www.micmiu.com * * @author Michael * */ public class HelloServerDemo2 { public static final int SERVER_PORT = 8090; public void startServer() { try { System.out.println("HelloWorld TThreadPoolServer start ...."); TProcessor tprocessor = new HelloWorldService.Processor<HelloWorldService.Iface>( new HelloWorldImpl()); TServerSocket serverTransport = new TServerSocket(SERVER_PORT); TThreadPoolServer.Args ttpsArgs = new TThreadPoolServer.Args( serverTransport); ttpsArgs.processor(tprocessor); ttpsArgs.protocolFactory(new TBinaryProtocol.Factory()); // 线程池服务模型，使用标准的阻塞式IO，预先创建一组线程处理请求。 TServer server = new TThreadPoolServer(ttpsArgs); server.serve(); } catch (Exception e) { System.out.println("Server start error!!!"); e.printStackTrace(); } } /** * @param args */ public static void main(String[] args) { HelloServerDemo server = new HelloServerDemo(); server.startServer(); } }
客户端Client代码和之前的一样，只要数据传输的协议一致即可，客户端测试成功，结果如下：
Thrify client result =: Hi,Michael welcome to my blog www.micmiu.com
TNonblockingServer 服务模型
使用非阻塞式IO，服务端和客户端需要指定 TFramedTransport 数据传输的方式。
编写服务端代码：HelloServerDemo3.java
package ThriftTest.ThriftTest; import org.apache.thrift.TProcessor; import org.apache.thrift.protocol.TCompactProtocol; import org.apache.thrift.server.TNonblockingServer; import org.apache.thrift.server.TServer; import org.apache.thrift.transport.TFramedTransport; import org.apache.thrift.transport.TNonblockingServerSocket; /** * blog http://www.micmiu.com * * @author Michael * */ public class HelloServerDemo3 { public static final int SERVER_PORT = 8090; public void startServer() { try { System.out.println("HelloWorld TNonblockingServer start ...."); TProcessor tprocessor = new HelloWorldService.Processor<HelloWorldService.Iface>( new HelloWorldImpl()); TNonblockingServerSocket tnbSocketTransport = new TNonblockingServerSocket( SERVER_PORT); TNonblockingServer.Args tnbArgs = new TNonblockingServer.Args( tnbSocketTransport); tnbArgs.processor(tprocessor); tnbArgs.transportFactory(new TFramedTransport.Factory()); tnbArgs.protocolFactory(new TCompactProtocol.Factory()); // 使用非阻塞式IO，服务端和客户端需要指定TFramedTransport数据传输的方式 TServer server = new TNonblockingServer(tnbArgs); server.serve(); } catch (Exception e) { System.out.println("Server start error!!!"); e.printStackTrace(); } } /** * @param args */ public static void main(String[] args) { HelloServerDemo server = new HelloServerDemo(); server.startServer(); } }
编写客户端代码：HelloClientDemo3.java
package ThriftTest.ThriftTest; import org.apache.thrift.TException; 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; import org.apache.thrift.transport.TTransportException; /** * blog http://www.micmiu.com * * @author Michael * */ public class HelloClientDemo3 { public static final String SERVER_IP = "localhost"; public static final int SERVER_PORT = 8090; public static final int TIMEOUT = 30000; /** * * @param userName */ public void startClient(String userName) { TTransport transport = null; try { transport = new TFramedTransport(new TSocket(SERVER_IP, SERVER_PORT, TIMEOUT)); // 协议要和服务端一致 TProtocol protocol = new TCompactProtocol(transport); HelloWorldService.Client client = new HelloWorldService.Client( protocol); transport.open(); String result = client.sayHello(userName); System.out.println("Thrify client result =: " + result); } catch (TTransportException e) { e.printStackTrace(); } catch (TException e) { e.printStackTrace(); } finally { if (null != transport) { transport.close(); } } } /** * @param args */ public static void main(String[] args) { HelloClientDemo client = new HelloClientDemo(); client.startClient("Michael"); } }
客户端的测试成功，结果如下：
Thrify client result =: Hi,Michael welcome to my blog www.micmiu.com
