Spring Data Redis过期密钥

Question

spring-servlet.xml
<!-- redis connection factory -->
<bean id="jedisConnFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" p:use-pool="true"/>

<!-- redis template definition -->
<bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate" 
    p:connection-factory-ref="jedisConnFactory"/>

RedisServiceImpl

@Autowired
private RedisTemplate<String, T> redisTemplate;

public RedisTemplate<String, T> getRedisTemplate() {
    return redisTemplate;
}

public void setRedisTemplate(RedisTemplate<String, T> redisTemplate) {
    this.redisTemplate = redisTemplate;
}

public void putData(String uniqueKey, String key, Object results) {

    redisTemplate.opsForHash().put(uniqueKey, key, results);
}

redisTemplate.expire(key, timeout, TimeUnit);

在这个expire方法中，我们需要提供uniquekey而不是key。但是我需要过期key而不是uniquekey。

那么，请帮助我如何处理过期密钥？

我正在使用Spring Data Redis，我正在使用@redishash(TimeTolive=300)注释在300秒后使我的实体过期。

以下是我的pom.xml摘录

我的redisconfig.class

@Configuration
@Log4j2
@EnableRedisRepositories(basePackageClasses = ConsentOTP.class)
public class RedisConfig {

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

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

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

    @Bean
    JedisConnectionFactory jedisConnectionFactory() {
        log.info("=================================================================");
        log.info("redis config : {} : {} ", host, port);
        log.info("=================================================================");

        RedisStandaloneConfiguration config = new RedisStandaloneConfiguration(host, port);
        config.setPassword(RedisPassword.of(password));
        return new JedisConnectionFactory(config);
    }

}

@RedisHash(value = "ConsentOTP", timeToLive = 300)
@Data
@NoArgsConstructor
public class ConsentOTP implements Serializable {

    private static final long serialVersionUID = 1708925807375596799L;

    private String id;
    private LocalDateTime timestamp;
    private String otp;

    public ConsentOTP(String personId, LocalDateTime timestamp, String otp) {
        this.id = personId;
        this.timestamp = timestamp;
        this.otp = otp;
    }
}

public interface ConsentOtpRepository extends CrudRepository<ConsentOTP, String> {

}
