In this video we learn to configure Users and Understand some important concepts of Spring Security.
Like
UserDetails - Used to represent a core spring security user
UserDetailsManager - Used as a service class which provides different manipulation methods like createUser / updateUser / deleteUser / loadUserByUserName
GrantedAuthoritity - Used to represent Roles / Authorities in a spring security environment
SimpleGrantedAuthority - Implementation of GrantedAuthority.You can use the constructor of the SimpleGrantedAuthority to create user roles.
InMemeoryUserDetailsManager - An implementation of UserDetailsManager which provides different methods to manipulate an user which will be store inside the server memory.
PasswordEncoder - Provides the encode and matches method to encode and decode password during user registration(create user) / login (Load User by Username)
NoopPasswordEncoder - Used, when you don't want to implement any password encoder for your application and you agree to store you password as plain text.
Today we will use all the above to create and store the user in our application and we will use the same to login to the application that we are building throughout.
