사용자 지정 유저와 패스워드 인코더를 이용하여 Spring Security 설정하기

Spring Security 설정을 하기 위해 security 폴더에 SpringSecurityConfiguration.class를 만들겠습니다.

SpringSecurityConfiguration.class

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.core.userdetails.User;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.provisioning.InMemoryUserDetailsManager;

import java.util.function.Function;

@Configuration
public class SpringSecurityConfiguration {

    @Bean
    public InMemoryUserDetailsManager createUserDetailsManager() {
        Function<String, String> passwordEncoder
                = input -> passwordEncoder().encode(input);
        UserDetails userDetails = User.builder()
                .passwordEncoder(passwordEncoder)
                .username("tester1")
                .password("testpassword")
                .roles("USER", "ADMIN")
                .build();

        return new InMemoryUserDetailsManager(userDetails);
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}
