Hey,
Looking for feedback on best way to implement a login action mechanism using
Struts2/Spring/JPA
Initially I had declared userName and userPassword setters inside my action
class and proceeded to call
a validateUser method inside my userService class.
the userService class injects a userdao object and I validate through calling
the userdao method validate(String username, String password).
This validate method instantiates a new UserEntity object and a query is
performed (jpa) grabbing all entities where login = username (which will be a
single entity since username must be unique).
I have this approach working. I would like to know if there is a better way to
do this though. Perhaps by declaring a UserEntity obj inside my LoginAction
class and having setters called for this obj.
Then I could change my validate to pass along the new UserEntity obj via
validate(UserEntity user).
My problem is I'm not entirely sure how I would compare against data in my db
using JPA?
Would your validate method then have a findAll() method and then iterate
through the list comparing against new UserEntity obj? That make sense?
That would seem very poor though to be since a large userlist could be taxing
to iterate over.
Any guidance or tips? :)
Thanks all!
Regards,
Paul
