UserDetailsService
UserDetailsService
is used by DaoAuthenticationProvider
for retrieving a username, password, and other attributes for authenticating with a username and password.
Spring Security provides in-memory and JDBC implementations of UserDetailsService
.
You can define custom authentication by exposing a custom UserDetailsService
as a bean.
For example, the following will customize authentication assuming that CustomUserDetailsService
implements UserDetailsService
:
This is only used if the AuthenticationManagerBuilder has not been populated and no AuthenticationProviderBean is defined.
