Spring Security Authentication using DynamoDB

Question

Does anyone know how to provide spring security authentication using DynamoDB? In other words, how would you convert/represent the following configAuthentication method using DynamoDB?

@Autowired
public void configAuthentication(AuthenticationManagerBuilder auth) 
throws Exception {
    auth.jdbcAuthentication().dataSource(dataSource)
            .usersByUsernameQuery("select username, password, enabled from appuser where username = ?")
            .authoritiesByUsernameQuery("select username, rolename from appuser natural join user_role natural join role where username = ?;");
}

github.com/michaellavelle/spring-security-spring-data-dynamodb is the closest I've found to an official answer, but it hasn't been updated in three years, so I'm skeptical of that package. You're already using github.com/derjust/spring-data-dynamodb which is currently maintained, but I don't see anything there about JWT / Spring Security. — Sarah Messer

You can use anything as a Spring Security authentication backend. You would need to write custom query logic in a class that implements the UserDetailsService interface and return a domain object that implements the UserDetails interface, but you can use that class.

Your configuration would like something like

  @Override
  public void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(myCustomDynamoDbDetailService);
}

Where myCustomDynamoDBDetailService is your class that implements UserDetailService and does the lookup by username from DynamoDB.
