1、添加依赖 jar
<dependency>
<groupId>org.apache.thrift</groupId>
<artifactId>libthrift</artifactId>
<version>0.8.0</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.6.1</version>
</dependency>
2、编写IDL文件 Hello.thrift
namespace java service.demo
service Hello {
string helloString(1:string para)
i32 helloInt(1:i32 para)
bool helloBoolean(1:bool para)
void helloVoid()
string helloNull()
}
3、生成代码
thrift -o <output directory> -gen java Hello.thrift
生成代码缩略图:
4、编写实现类、实现Hello.Iface:
缩略图:
5、编写服务端,发布(阻塞式IO + 多线程处理)服务。
/** * 阻塞式、多线程处理 * * @param args */ @SuppressWarnings({ "unchecked", "rawtypes" }) public static void main(String[] args) { try { //设置传输通道,普通通道 TServerTransport serverTransport = new TServerSocket(7911); //使用高密度二进制协议 TProtocolFactory proFactory = new TCompactProtocol.Factory(); //设置处理器HelloImpl TProcessor processor = new Hello.Processor(new HelloImpl()); //创建服务器 TServer server = new TThreadPoolServer( new Args(serverTransport) .protocolFactory(proFactory) .processor(processor) ); System.out.println("Start server on port 7911..."); server.serve(); } catch (Exception e) { e.printStackTrace(); } }
6、编写客户端,调用(阻塞式IO + 多线程处理)服务:
public static void main(String[] args) throws Exception { // 设置传输通道 - 普通IO流通道 TTransport transport = new TSocket("localhost", 7911); transport.open(); //使用高密度二进制协议 TProtocol protocol = new TCompactProtocol(transport); //创建Client Hello.Client client = new Hello.Client(protocol); long start = System.currentTimeMillis(); for(int i=0; i<10000; i++){ client.helloBoolean(false); client.helloInt(111); client.helloNull(); client.helloString("dongjian"); client.helloVoid(); } System.out.println("耗时:" + (System.currentTimeMillis() - start)); //关闭资源 transport.close(); }
现在已完成整个开发过程,超级无敌简单。
其中服务端使用的协议需要与客户端保持一致。
-------------------------------------------------------------------------------------------------------------------
上面展示了普通且常用的服务端和客户端,下面请看非阻塞IO,即java中的NIO:
基于非阻塞IO(NIO)的服务端:
public static void main(String[] args) { try { //传输通道 - 非阻塞方式 TNonblockingServerTransport serverTransport = new TNonblockingServerSocket(7911); //异步IO,需要使用TFramedTransport,它将分块缓存读取。 TTransportFactory transportFactory = new TFramedTransport.Factory(); //使用高密度二进制协议 TProtocolFactory proFactory = new TCompactProtocol.Factory(); //设置处理器 HelloImpl TProcessor processor = new Hello.Processor(new HelloImpl()); //创建服务器 TServer server = new TThreadedSelectorServer( new Args(serverTransport) .protocolFactory(proFactory) .transportFactory(transportFactory) .processor(processor) ); System.out.println("Start server on port 7911..."); server.serve(); } catch (Exception e) { e.printStackTrace(); } }
调用非阻塞IO(NIO)服务的客户端:
public static void main(String[] args) throws Exception { //设置传输通道,对于非阻塞服务,需要使用TFramedTransport,它将数据分块发送 TTransport transport = new TFramedTransport(new TSocket("localhost", 7911)); transport.open(); //使用高密度二进制协议 TProtocol protocol = new TCompactProtocol(transport); //创建Client Hello.Client client = new Hello.Client(protocol); long start = System.currentTimeMillis(); for(int i=0; i<10000; i++){ client.helloBoolean(false); client.helloInt(111); client.helloNull(); client.helloString("360buy"); client.helloVoid(); } System.out.println("耗时:" + (System.currentTimeMillis() - start)); //关闭资源 transport.close(); }
-----------------------------------------------------------------------------------------------------------------------------------
客户端异步调用:
/** 调用[非阻塞IO]服务,异步 */ public static void main(String[] args) { try { //异步调用管理器 TAsyncClientManager clientManager = new TAsyncClientManager(); //设置传输通道,调用非阻塞IO。 final TNonblockingTransport transport = new TNonblockingSocket("localhost", 7911); //设置协议 TProtocolFactory protocol = new TCompactProtocol.Factory(); //创建Client final Hello.AsyncClient client = new Hello.AsyncClient(protocol, clientManager, transport); // 调用服务 System.out.println("开始:" + System.currentTimeMillis()); client.helloBoolean(false, new AsyncMethodCallback<Hello.AsyncClient.helloBoolean_call>() { public void onError(Exception exception) { System.out.println("错误1: " + System.currentTimeMillis()); } public void onComplete(helloBoolean_call response) { System.out.println("完成1: " + System.currentTimeMillis()); try { client.helloBoolean(false, new AsyncMethodCallback<Hello.AsyncClient.helloBoolean_call>() { public void onError(Exception exception) { System.out.println("错误2: " + System.currentTimeMillis()); } public void onComplete(helloBoolean_call response) { System.out.println("完成2: " + System.currentTimeMillis()); transport.close(); } }); } catch (TException e) { e.printStackTrace(); } } }); System.out.println("结束:" + System.currentTimeMillis()); Thread.sleep(5000); } catch (Exception e) { e.printStackTrace(); } }
