Windows system Normal but file not found on Linux system

Problem Description: A recent project development environment is a Windows system, and the formal environment is a Linux system. Verification code picture in the development environment is normal, but in the formal environment has been reported 404.

Cause of the problem: filedir = new file (Realpath + "resource\\picture"); there is a problem with the writing path, and the Linux system does not support the way the backslash is spelled.

Workaround: Change \ \ to/From, so that both Windows and Linux systems are normal. Correct wording:file dir = new file (Realpath + "resource/picture");

Windows system Normal but file not found on Linux system
