Question

i want to implement spring security login and remember me
and i am confused between using jdbc-user-service or user-service-ref
as my authentication-provider
can anyone please describe to me what is the difference between both, when to go for one or the other, coz what i can see is that both are used to lookup user.

Answer 1

<jdbc-user-service> configures a built-in JdbcDaoImpl as a source of user details. It loads user detials from predefined database tables using JDBC.

If you need to customize user lookup, you can create a custom UserDetailsService instead and reference it with user-service-ref. It can be useful in the following cases:

• You need a more complex user lookup logic
• You want to reuse existing services instead of doing raw JDBC lookups
• You want to add extra information to UserDetails objects returned by UserDetailsService
• Etc
