Intellij IDEA实现 一个简单的thrift Demo

Thrift是一个由Facebook开发，跨语言的RPC框架，使用IDL(接口定义语言)描述。支持多种通信协议：TCompactProtocol(压缩)、TBinaryProtocol(二进制)和TJSONProtocol(json)。
 

一，需使用接口定义语言描述接口，Test.thrift使用命令生成文件，见下图。由于本人的thrift版本为0.8.0，生成的java代码，有些代码在java1.7有问题，做此修改，将@override去掉，catch到某个异常，直接调用printSatck打印，而非throw new xxxException。

namespace java com.thrift.demo

service  HelloWorldService {
  string sayHello(1:string name)
}

$thrift -gen java Test.thrift

二、新建一个maven项目，新建包名com.thrift.demo，将生成的java文件拷贝到此下。其中pom.xml文件加入依赖如下

<build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>7</source>
          <target>7</target>
        </configuration>
      </plugin>
    </plugins>
  </build>
  <dependencies>
    <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>

新建客户端，helloClient，代码如下，代码都很简单，都是thrift的模块格式

package com.thrift.demo;

import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;

public class helloClient {

  public static final String SERVER_IP = "127.0.0.1";
  public static final int SERVER_PORT = 9090;
  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 (Exception e) {
      e.printStackTrace();
    } finally {
      if (null != transport) {
        transport.close();
      }
    }
  }

  /**
   * @param args
   */
  public static void main(String[] args) {
    System.out.println("thrift client main executing...");
    helloClient client = new helloClient();
    client.startClient("THRIFT");

  }
}

将此客户端打包成jar,打包方法见本人另一篇博客
三、新建另一个maven工程，同理客户端，拷贝thrift生成的接口文件，新建包，再新建类服务端，代码如下：

import org.apache.thrift.TProcessor;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TSimpleServer;
import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;

public class helloServer {
  public static final int SERVER_PORT = 9090;

  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) {
    System.out.println("thrift server executing...");
    helloServer server = new helloServer();
    server.startServer();
  }
}

新建Iface的实现类代码

public class HelloWorldImpl implements HelloWorldService.Iface {

  @Override
  public String sayHello(String name) {
    System.out.println("client name:" + name);
    return name;
  }
}

将jar上传到linux下，直接使用下述命令启动客户端和服务器端。

$java -jar xxx.jar
