Java API——RMIIO入门教程（2）远程流传输示例之RMIIO服务源码-优快云博客

本文介绍了一个基于Java RMI的远程文件传输服务的具体实现。该服务定义了接口RMIServiceInterface，通过该接口可以接收远程输入流并将其保存到本地文件系统中。实现类RMIServiceImplementationClass展示了如何使用RemoteInputStream进行文件接收，并提供了文件存储的方法。

1. RMI Service Interface

package com.sinosuperman.rmiio2; import java.rmi.Remote; import java.rmi.RemoteException; import com.healthmarketscience.rmiio.RemoteInputStream; public interface RmiioService2 extends Remote { public void sendFile(String fileName, RemoteInputStream inFile) throws RemoteException; }

2. RMI Service Implementation Class

package com.sinosuperman.rmiio2; import java.io.BufferedInputStream; import java.io.File; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.Serializable; import java.rmi.RemoteException; import java.rmi.server.UnicastRemoteObject; import com.healthmarketscience.rmiio.RemoteInputStream; import com.healthmarketscience.rmiio.RemoteInputStreamClient; public class RmiioServiceImpl2 extends UnicastRemoteObject implements Serializable, RmiioService2 { private static final long serialVersionUID = -5776252535031796604L; public RmiioServiceImpl2() throws RemoteException { } @Override public void sendFile(String fileName, RemoteInputStream inFile) throws RemoteException { try { InputStream inStream = RemoteInputStreamClient.wrap(inFile); store(inStream, "temp" + File.separator + fileName); } catch (IOException e) { e.printStackTrace(); } } private static void store(InputStream inStream, String filePath) { try { BufferedInputStream inStreamBuff = new BufferedInputStream(inStream); FileOutputStream fileOutStream; fileOutStream = new FileOutputStream(filePath); int size = 0; byte[] byteBuff = new byte[1024]; while ( (size = inStreamBuff.read(byteBuff)) != -1) { fileOutStream.write(byteBuff, 0, size); } fileOutStream.close(); inStreamBuff.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
