Apache Thrift - java开发详解
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();
 - }
 - }
