利用SMB jcifs实现对windows中的共享文件夹的操作
需求是在本地上传文件到服务器上,服务器是windows的,使用共享文件夹提供权限给你的。
利用第三方:
CIFS (Common Internet File System)
SMB(Server Message Block)
CIFS是公共的或开放的SMB协议版本,并由Microsoft使用。SMB协议(见最后的名词解释)现在是局域网上用于服务器文件访问和打印的协议。象SMB协议一样,CIFS在高层运行,而不象TCP/IP协议那样运行在底层。CIFS可以看做是应用程序协议如文件传输协议和超文本传输协议的一个实现。
作用:
CIFS 可以使您达到以下功能: 1.访问服务器本地文件并读写这些文件 2.与其它用户一起共享一些文件块 3.在断线时自动恢复与网络的连接 4.使用西欧字符文件名
JCIFS的开发方法类似java的文件操作功能,它的资源url定位:smb://{user}:{password}@{host}/{path},smb为协议名,user和password分别为共享文件机子的登陆名和密码,@后面是要访问的资源的主机名或IP地址
我的经验是将SMBFile当成普通File操作
例子:

导入的有关jar:
<dependency> <groupId>org.samba.jcifs</groupId> <artifactId>jcifs</artifactId> <version>1.2.19</version> </dependency>
更多以后用到再更新。
