Spring Boot Java web page using Maven and IntelliJ.

I have set up server successfully (runs fine in localhost:8080), but I need step-by-step help along with source code of how to fulfil the following conditions:

1. Create a web login page;

2. The page should have two fields "Login" and "Password";

3. After clicking on the "Login" button, the input strings must be sent to the backend and checked with constant values;

4. If they match, then open a new page with the text "Home page", otherwise show a red message about the wrong password;

5. Login check can ignore letters case.

Any help would be greatly appreciated.
