I am learning Java and am having a problem with a form using Spring. I even found a similar problem here on the forum but a little different from mine.
It is a basic login page, containing only two fields, login and password. The problem is that when I submit the form, the password is filled in correctly but the login always comes with NULL.
Something’s missing or I’m making a mistake in the code?
Any comments and/or criticisms to this code are welcome, after all I am here to learn, remembering that it is just a simple code to assimilate knowledge.
Thank you in advance to anyone who can help. Thank you very much!
