将图片上传到另一台服务器处理

    最近做项目要将图片上传到另一台服务器，查资料实现了三种方法，下面就介绍一下方法。

1.sftp(最简单)

package com.xiang;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.Properties;
import java.util.Vector;

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.SftpException;

public class Main {
	/*host 主机
	port 端口
	username 用户名
	password 密码*/
	public ChannelSftp connect(String host, int port, String username,
			String password) {
		ChannelSftp sftp = null;
		try {
			JSch jsch = new JSch();
			jsch.getSession(username, host, port);
			Session sshSession = jsch.getSession(username, host, port);
			sshSession.setPassword(password);
			Properties sshConfig = new Properties();
			sshConfig.put("StrictHostKeyChecking", "no");
			sshSession.setConfig(sshConfig);
			sshSession.connect();
			Channel channel = sshSession.openChannel("sftp");
			channel.connect();
			sftp = (ChannelSftp) channel;
		} catch (Exception e) {

		}
		return sftp;
	}

	/*directory 上传的目录
	uploadFile 要上传的文件*/
	public void upload(String directory, String uploadFile, ChannelSftp sftp) {
		try {
			sftp.cd(directory);
			File file = new File(uploadFile);
			sftp.put(new FileInputStream(file), file.getName());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
     /*downloadFile 下载的文件
     saveFile 存在本地的路径*/
	public void download(String directory, String downloadFile,
			String saveFile, ChannelSftp sftp) {
		try {
			sftp.cd(directory);
			File file = new File(saveFile);
			sftp.get(downloadFile, new FileOutputStream(file));
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	/*directory 要删除文件所在目录
    deleteFile 要删除的文件*/
	public void delete(String directory, String deleteFile, ChannelSftp sftp) {
		try {
			sftp.cd(directory);
			sftp.rm(deleteFile);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	//directory 要列出的目录
	public Vector listFiles(String directory, ChannelSftp sftp)
			throws SftpException {
		return sftp.ls(directory);
	}

	public static void main(String[] args) {
		Main sf = new Main();
		String host = "192.168.17.128";
		int port = 22;
		String username = "root";
		String password = "mgxmgx";
		String directory = "/nginx/html/";
		String uploadFile = "D:\\bg.jpg";
		//String downloadFile = "upload.txt";
		//String saveFile = "D:\\tmp\\save.txt";
		//String deleteFile = "delete.txt";
		ChannelSftp sftp = sf.connect(host, port, username, password);
		sf.upload(directory, uploadFile, sftp);
		//sf.download(directory, downloadFile, saveFile, sftp);
		//sf.delete(directory, deleteFile, sftp);
		try {
			System.out.println("成功");
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

需要的jar包：jsch-0.1.42-sources.jar   jsch-0.1.42.jar

还可参考：JSch - Java实现的SFTP（文件上传详解篇）

2.ftp(中等)

需要搭建ftp服务

Linux平台下快速搭建FTP服务器

package com.xiang;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import org.apache.commons.io.IOUtils;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;


public class Test {

	public static void main(String[] args) {

		FTPClient ftpClient = new FTPClient();
		ftpClient.setControlEncoding("GBK");
        FileInputStream fis = null;

        try {
            ftpClient.connect("192.168.17.128");
            ftpClient.login("test", "123456");
            
            int reply = ftpClient.getReplyCode();  
            
            // 以2开头的返回值就会为真  
           
            if (!FTPReply.isPositiveCompletion(reply)) {  
           
             ftpClient.disconnect();  
           
             System.out.println("连接服务器失败");  
           
                 return;  
           
            }  
            System.out.println("登陆服务器成功"); 
            File srcFile = new File("D:\\bg.jpg");
            fis = new FileInputStream(srcFile);
            ftpClient.setFileType(ftpClient.BINARY_FILE_TYPE);
            ftpClient.makeDirectory("123");
            ftpClient.changeWorkingDirectory("123");
            ftpClient.storeFile("new.jpg", fis);
           
        } catch (IOException e) {
            e.printStackTrace();
            throw new RuntimeException("FTP客户端出错！", e);
        } finally {
            IOUtils.closeQuietly(fis);
        	try {
				fis.close();
			} catch (IOException e1) {
				e1.printStackTrace();
			}
            try {
                ftpClient.disconnect();
            } catch (IOException e) {
                e.printStackTrace();
                throw new RuntimeException("关闭FTP连接发生异常！", e);
            }
        } 
	}

}

需要的jar包：commons-io-1.4-javadoc.jar commons-io-1.4-sources.jar commons-io-1.4.jar

3.通过nginx上传模块上传至另一服务器nginx

相当坑，n年前的东西了，配置相当难虽然配置成功了，但感觉不好用
想配置的话可参考http://www.tuicool.com/wx/aUrAzm
下载的东西最好按照文章中来，我起初用的nginx1.9.0怎么配置都不行，坑死个人    本人配置了一下午，有兴趣的可以实现一下
