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

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;

	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
