spring security UserDetailsService. In this lesson, we will talk about the #springsecurity #userdetailsservice.We will be doing a database backed user authentication using by implementing a customs user details service.
In this lesson, we will learn what is UserDetailsService and how this is used in Spring security? We will create a custom UserDetailsService and will be injecting it to out #DaoAuthenticationProvider.
We are assuming that you have already gone through previous lessons and know how the #authenticationproviders works in spring security.

Can I have multiple userdetailsservice implementations? If so, How could I add them to auth provider?

[@javadevjournal]

is it with 2 different endpoints? Alternatively, you can always have strategy based workflow inside your user-details service.

[@toshiroh5997]

@@javadevjournal I had an idea similar to this strategy based workflow..., I created two service classes that have a method for searching for the user by username, then I came up with a userDetailsService and put a map... I switch between them inside the filter I created extending UsernamePasswordAuthenticationFilter, I passe a dto which has username, password and type, this type is the key for the map inside the UserDetailsService

@@javadevjournal do you think this is a good solution?

[@javadevjournal]

@@toshiroh5997 is there a reason you need 2 different user details services? We generally use it in case handling multiple entry points and want to handle them differently.

@@javadevjournal it's because the number of.columns in each user is different I dont know how to proceed
