java从共享文件夹下载文件

使用jcifs1.3.1.jar,maven引入，配置如下：

    jcifs
    jcifs
    1.3.17

具体实现代码如下：

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.MalformedURLException;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import jcifs.smb.SmbException;
import jcifs.smb.SmbFile;
import jcifs.smb.SmbFileInputStream;
import jcifs.smb.SmbFileOutputStream;

		} catch (MalformedURLException e) {

注意： 一般文件路径使用 ‘\’,smb取共享文件路径使用'/'
