The tool is telling you that public methods should be final. That way a subclass won't be able to change how a class operates.

    public final UserDAO getUserDAO() {
        return userDAO;
    }

Read the corresponding documentation
Make the method final
or make the class final
or disable the corresponding check if you don't want to stick to that programming paradigm
