Java | Hibernate | VRaptor | PostgreSQL | TomCat
Backend features:
- Register users;
- Save user data (such as: name, email, time and date of registration) in the Database table;
- Validate if the data that the user registers is in accordance with the expected;
- Return error messages to the user if he is registering wrong data.
***
I developed the entire MVC Architecture in Java;
- Model: models the database table, with create and update methods; gets and setters to access and change each item in the table as a variable;
- View: each web page is a JSP file (HTML that JAVA understands) and has a controller, I can have methods in the controllers or directly in the JSP;
- Controller: are exactly the files that contain all the methods.
