Javaweb distinguishes between PC-side and mobile-side __java

Javaweb: Determine if the current request is for mobile device accessCategory: "Java" "Good Technology to share" "Javaweb"

This time is doing on the PC side of the business, the result manager found me said, may have to do the mobile end of the application, background logic or with my writing logic, but need to change some, see how to deal with.

Since the mobile end is slightly different from the PC side, I think it is best to make a unified judgment in one place and not to change the original code, so as to reduce the number of bugs to a certain extent. My idea is to first determine whether the current request is a mobile end, then set an identity to the session, and then you can handle it casually. Whether you are dealing alone, or unified processing, direct reading session can make the corresponding judgments.

I encapsulated it into a class that is now shared with everyone:
