24년 1월 24일(수요일) - 76번째 TIL : StringRedisTemplate

 

@Configuration
public class RedisConfig {

    @Value("${spring.data.redis.host}")
    private String host;

    @Value("${spring.data.redis.port}")
    private Integer port;

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory(host, port);
    }

    @Bean
    public RedisTemplate<String, Object> redisTemplate() {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory());
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

redis config 를 설정 중에 String 자료구조를 이용하니 cli 에서 값을 확인했을 때 value외에 이상한 것들이 딸려 붙어있는 것을 발견했다. 

@SpringBootTest
public class RedisTest {

    @Autowired
    RedisTemplate<String, String> redisTemplate;

    @Test
    void test01() {
        String loginId = "loginId01";
        String refreshToken = "aaabbbccc";
        redisTemplate.opsForValue().set("refreshToken:" + loginId, refreshToken);

        String tokenInRedis = redisTemplate.opsForValue().get("refreshToken:" + loginId);
        System.out.println("tokenInRedis = " + tokenInRedis);
    }
}

 

127.0.0.1:6379> get refreshToken:loginId01
"\xac\xed\x00\x05t\x00\taaabbbccc"

 

 

RedisTemplate<String, Object> 로 되어 있어서, Object를 구별할 값을 넣어준 게 아닌가 하는 생각이 든다. 

 

 

 

@Configuration
public class RedisConfig {

    @Value("${spring.data.redis.host}")
    private String host;

    @Value("${spring.data.redis.port}")
    private Integer port;

    @Bean
    public RedisConnectionFactory redisConnectionFactory() {
        return new LettuceConnectionFactory(host, port);
    }

    @Bean
    public StringRedisTemplate stringRedisTemplate() {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory(redisConnectionFactory());
        return stringRedisTemplate;
    }
}

@SpringBootTest
public class RedisTest {

    @Autowired
    StringRedisTemplate stringRedisTemplate;

    @Test
    void test01() {
        String loginId = "loginId01";
        String refreshToken = "aaabbbccc";
        stringRedisTemplate.opsForValue().set("refreshToken:" + loginId, refreshToken);

        String tokenInRedis = stringRedisTemplate.opsForValue().get("refreshToken:" + loginId);
        System.out.println("tokenInRedis = " + tokenInRedis);
    }
}

127.0.0.1:6379> get refreshToken:loginId01
"aaabbbccc"
