I'm trying to make a Login app with JSF, and I found in forums that a lot of people use LoginByUsername(or findByUsername or whatever they call it ,anyway a method that does find the username and returns the user and uses SQL) and they put it in the facade(session bean for entity class) !
But the facade itself gives us something called find(Object id) ,and the id is username .
so what's better : using find or making its own method(that uses SQL)? and why?
thanks in advance for your help
If the username is used as id in your app, then it's no need to write a new method LoginByUsername/findByUsername, since you have already have the method find(Object id), which can achieve the function findByUsername will do.
But, since it's a Login App, i think it's better to provide a method called findByUserAndPassword, and if no result is returned, tell the user that user or password is wrong, which it's commonly used in many website.
