/**
* 基于apache组织的commonNet开源组件实现ftp客户端<br>
* 本程序运行依赖于一个config成员变量属性,其是一个属性(Properties)对象<br>
* 系统要求这个config对象,必需有如下属性key:<br>
* server(ftp服务器ip地址或域名)<br>
* username(登录用户名)<br>
* password(登录密码)<br>
* 如下属性key是可选的:<br>
* systemKey(ftp服务器的操作系统key,如window)<br>
* serverLanguageCode(ftp服务器使用的语言,如zh)<br>
* <br>
* 本程序是线程安全,在每一个上传时都将创建ftp连接,上传结束后再关闭ftp连接<br>
*
* 例子:<br>
* InputStream localIn = new FileInputStream("c:\\计算机.txt");<br>
*
* java.util.Properties config = new Properties();<br>
* config.setProperty("server", "192.168.5.120");<br>
* config.setProperty("username", "upload");<br>
* config.setProperty("password", "upload");<br>
*
* FtpClientCommonNetImpl client = new FtpClientCommonNetImpl();<br>
* client.setConfig(config);<br>
* client.upload(localIn, "/aaa/计算机.txt", true);<br>
