java ftp上传文件

Question

用 java 上传 ftp 文件如果是在 window 环境执行，就可以上传成功，但将同样的代码部署到 linux 上传就不成功，但也没有报错

boolean b = ftp.storeFile(new String(file2.getName().getBytes("UTF-8"),"iso-8859-1"), input);

windows 执行的时候 b = true 上传成功
linux 同样的代码 执行时 b = false

下面是完整的代码 ，这和操作系统有关系吗?

Pay attention to the path separator, it is inconsistent between windows and linux, which will cause the file to not be found!
