Login Service
To check to see if the user values being passed through are connected to a valid user combination in the database, the
application uses the
login
method in
UserService.
As shown in the
UserService
code in Listing 7-21, the result of
the
getByUsername
method is assigned to the
tempUser
variable.
If the result is not null, the result is set on the
User
object of the
GraphStory
service object. Otherwise, a message
is added to the
GraphStory
error property and returned to the controller along with the original
User
object.
