Apache Thrift - java開發詳解

1、添加依賴 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、編寫IDL檔案 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、產生代碼

thrift -o <output directory> -gen java Hello.thrift

產生代碼縮圖：

4、編寫實作類別、實現Hello.Iface：

縮圖：

5、編寫服務端，發布（阻塞式IO + 多執行緒）服務。

/** * 阻塞式、多執行緒 *  * @param args */@SuppressWarnings({ "unchecked", "rawtypes" })public static void main(String[] args) {try {//設定傳輸通道，普通通道TServerTransport serverTransport = new TServerSocket(7911);//使用高密度二進位協議TProtocolFactory proFactory = new TCompactProtocol.Factory();//設定處理器HelloImplTProcessor processor = new Hello.Processor(new HelloImpl());//建立伺服器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、編寫用戶端，調用（阻塞式IO + 多執行緒）服務：

public static void main(String[] args) throws Exception {// 設定傳輸通道 - 普通IO流通道TTransport transport = new TSocket("localhost", 7911);transport.open();//使用高密度二進位協議TProtocol protocol = new TCompactProtocol(transport);//建立ClientHello.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("耗時：" + (System.currentTimeMillis() - start));//關閉資源transport.close();}

現在已完成整個開發過程，超級無敵簡單。

其中服務端使用的協議需要與用戶端保持一致。

-------------------------------------------------------------------------------------------------------------------

上面展示了普通且常用的服務端和用戶端，下面請看非阻塞IO，即java中的NIO：

基於非阻塞IO（NIO）的服務端：

public static void main(String[] args) {try {//傳輸通道 - 非阻塞方式TNonblockingServerTransport serverTransport = new TNonblockingServerSocket(7911);//非同步IO，需要使用TFramedTransport，它將分塊緩衝讀取。TTransportFactory transportFactory = new TFramedTransport.Factory();//使用高密度二進位協議TProtocolFactory proFactory = new TCompactProtocol.Factory();//設定處理器 HelloImplTProcessor processor = new Hello.Processor(new HelloImpl());//建立伺服器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();}}

調用非阻塞IO（NIO）服務的用戶端：

public static void main(String[] args) throws Exception {//設定傳輸通道，對於非阻塞服務，需要使用TFramedTransport，它將資料分塊發送TTransport transport = new TFramedTransport(new TSocket("localhost", 7911));transport.open();//使用高密度二進位協議TProtocol protocol = new TCompactProtocol(transport);//建立ClientHello.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("耗時：" + (System.currentTimeMillis() - start));//關閉資源transport.close();}

-----------------------------------------------------------------------------------------------------------------------------------

用戶端非同步呼叫：

/** 調用[非阻塞IO]服務，非同步 */public static void main(String[] args) {try {//非同步呼叫管理器TAsyncClientManager clientManager = new TAsyncClientManager();//設定傳輸通道，調用非阻塞IO。final TNonblockingTransport transport = new TNonblockingSocket("localhost", 7911);  //設定協議            TProtocolFactory protocol = new TCompactProtocol.Factory();              //建立Client            final Hello.AsyncClient client = new Hello.AsyncClient(protocol, clientManager, transport);// 調用服務             System.out.println("開始：" + System.currentTimeMillis());            client.helloBoolean(false, new AsyncMethodCallback<Hello.AsyncClient.helloBoolean_call>() {public void onError(Exception exception) {System.out.println("錯誤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("錯誤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("結束：" + System.currentTimeMillis());Thread.sleep(5000);} catch (Exception e) {e.printStackTrace();}}
