Auth Server Session 정보 Redis 에 저장

Redis 활성화

build.gradle

......
dependencies {
    // ......
    implementation 'org.springframework.boot:spring-boot-starter-data-redis'
    implementation 'org.springframework.session:spring-session-data-redis'
    // ......

RedisConfig.java

@RequiredArgsConstructor
@Configuration
@EnableRedisRepositories
public class RedisConfig {

    private final RedisProperties redisProperties;

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory(redisProperties.getHost(), redisProperties.getPort());
    }

    @Bean
    public RedisTemplate<?, ?> redisTemplate() {
        RedisTemplate<byte[], byte[]> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory());
        return redisTemplate;
    }
}

Session 정보 Redis 에 저장

SessionConfig.java

@Configuration
public class SessionConfig implements BeanClassLoaderAware {

    private ClassLoader loader;

    @Bean
    public RedisSerializer<Object> springSessionDefaultRedisSerializer() {
        return new GenericJackson2JsonRedisSerializer(objectMapper());
    }

    private ObjectMapper objectMapper() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.registerModules(SecurityJackson2Modules.getModules(this.loader));
        return mapper;
    }

    @Override
    public void setBeanClassLoader(ClassLoader classLoader) {
        this.loader = classLoader;
    }
}

Entity Deserializer 생성

UserDeserializer.java

public class UserDeserializer extends JsonDeserializer<User> {

    @Override
    public User deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {

        ObjectCodec objectCodec = jsonParser.getCodec();
        JsonNode node = objectCodec.readTree(jsonParser);

        return User.builder()
                .userId(node.get("userId").longValue())
                .email(node.get("email").asText())
                .password(node.get("password").asText())
                .firstName(node.get("firstName").asText())
                .lastName(node.get("lastName").asText())
                .roles(node.get("roles").asText())
                .build();
    }
}

@JsonDeserialize(using = UserDeserializer.class)
@Builder
@Getter
@NoArgsConstructor
@AllArgsConstructor
@Entity
@Table(name = "tbl_user")
public class User implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long userId;

    // ......
}
