Spring boot Redis get null in another project - spring-boot

Question

I have two projects that use Spring boot with Redis. In the first project, I have saved data into Redis cache.
Then, in the second project, when I get data from Redis that I saved in project one it is always null, and project one is also null when I try to get data from Redis that I have saved in project two.
Both projects use the dto as below.
#Data
#EqualsAndHashCode(callSuper = false)
#NoArgsConstructor
#AllArgsConstructor
#JsonInclude(content = Include.NON_NULL)
public class AccountDto implements Serializable {
#JsonIgnore
private static final long serialVersionUID = -2006838697507278668L;
#JsonProperty("account_no")
private String accountNo;
#JsonProperty("account_type")
private String accountType;
#JsonProperty("customer_no")
private String customerNO;
#JsonProperty("entity_code")
private String entityCode;
#JsonProperty("auth_stat")
private String authStat;
#JsonProperty("create_at")
#Temporal(TemporalType.TIMESTAMP)
private Date createAt;
}
Redis configuration
#Configuration
#RefreshScope
#EnableRedisRepositories
public class RedisConfiguration {
#Value("${spring.redis.host: ''}")
private String redisHost;
#Value("${spring.redis.port: ''}")
private int redisPort;
#Bean
public JedisConnectionFactory connectionFactory() {
RedisStandaloneConfiguration configuration = new RedisStandaloneConfiguration();
configuration.setHostName(redisHost);
configuration.setPort(redisPort);
return new JedisConnectionFactory(configuration);
}
#Bean
public RedisTemplate<String, Object> redisTemplate() {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(connectionFactory());
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new StringRedisSerializer());
return template;
}
}
This class I have created two methods, one for saving and getting data from Redis
#RequiredArgsConstructor
#Service
public class AccountDtoCache {
private static final String HASH_KEY_ACCOUNT = "Account";
private static HashOperations<String, String, AccountDto> hashOperations;
private final RedisTemplate<String, Object> redisTemplate;
#PostConstruct
private synchronized void init() {
hashOperations = redisTemplate.opsForHash();
}
public void save(AccountDto account) {
hashOperations.put(HASH_KEY_ACCOUNT, account.getAccountNo(), account);
}
public static AccountDto getByAccountNo(String account) {
return hashOperations.get(HASH_KEY_ACCOUNT, account);
}
}
I try to get data from Redis as below.
When I debug, it's always null in other projects, but it's working with the same project that I have saved data into Redis.
AccountDtoCache.getByAccountNo("accountNo");
I fixed the issue above with two steps as below
I changed both of the projects package names to the same package name
Redis config
#Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<String, Object> template = new RedisTemplate<>();
GenericJackson2JsonRedisSerializer serializer = new GenericJackson2JsonRedisSerializer();
template.setConnectionFactory(redisConnectionFactory);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(new StringRedisSerializer());
template.setHashKeySerializer(serializer);
template.setHashValueSerializer(serializer);
return template;
}
