thrift java 例子入门（hello world）

刚学习thrift,网上参考了一些资料，进行thrift入门例子的搭建。
0 . maven文件

 <dependencies>        <dependency>            <groupId>org.apache.thrift</groupId>            <artifactId>libthrift</artifactId>            <version>0.10.0</version>        </dependency>        <dependency>            <groupId>org.slf4j</groupId>            <artifactId>slf4j-log4j12</artifactId>            <version>1.6.1</version>        </dependency> </dependencies>

1 . thrift文件编写 helloworld.thrift

namespace java com.thrift.demoservice  HelloWorldService {  string sayHello(1:string name)}

2 . thrift文件生成java文件

package com.thrift.demo;@SuppressWarnings({"cast", "rawtypes", "serial", "unchecked", "unused"})@javax.annotation.Generated(value = "Autogenerated by Thrift Compiler (0.10.0)", date = "2017-04-16")public class HelloWorldService {  public interface Iface {    public String sayHello(String username) throws org.apache.thrift.TException;  }  }

其中生成的java文夹还有很多其他相关的方法，这里不再详细展示。

3 . 编写服务端

public class HelloServerDemo {    public static final int SERVER_PORT = 9099;    public void startServer() {        try {            System.out.println("server start ....");            TProcessor tprocessor = new HelloWorldService.Processor(new HelloWorldImpl());            TServerSocket serverTransport = new TServerSocket(SERVER_PORT);            TServer.Args tArgs = new TServer.Args(serverTransport);            tArgs.processor(tprocessor);            tArgs.protocolFactory(new TBinaryProtocol.Factory());            TServer server = new TSimpleServer(tArgs);            server.serve();        } catch (Exception e) {            System.out.println("Server happened error!!!");            e.printStackTrace();        }    }    /**     * @param args     */    public static void main(String[] args) {        HelloServerDemo server = new HelloServerDemo();        server.startServer();    }}

4 . 编写客户端

public class HelloClientDemo {    public static final String SERVER_IP = "localhost";    public static final int SERVER_PORT = 9099;    public static final int TIMEOUT = 30000;    /**     *     * @param userName     */    public void startClient(String userName) {        TTransport transport = null;        try {            transport = new TSocket(SERVER_IP, SERVER_PORT, TIMEOUT);            TProtocol protocol = new TBinaryProtocol(transport);            HelloWorldService.Client client = new HelloWorldService.Client(                    protocol);            transport.open();            String result = client.sayHello(userName);            System.out.println("thrift remote call : " + 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("THRIFT");    }}

5 启动server和client
