Springboot with Redis Sentinals getting UnsatisfiedDependencyException - spring-boot

Question

I am not able to connect with Redis Sentinal nodes using Spring boot. I am getting UnsatisfiedDependencyException while creating bean cacheManager and localCacheManager. I am not getting where I am doing wrong. Can anyone please help me out.
Using Spring boot version - 2.6. Maven dependencies are -
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<version>2.6.6</version>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>4.2.2</version>
<optional>true</optional>
</dependency>
Code -
#EnableAutoConfiguration
#Configuration
#EnableCaching
public class RedisCacheConfig {
private final Logger logger = LoggerFactory.getLogger(RedisCacheConfig.class);

} catch(Exception e) {
e.printStackTrace();
}
return factory;
}
#Bean
public RedisSentinelConfiguration sentinelConfig() {
String[] nodes = StringUtils.commaDelimitedListToStringArray(sentinelNodes);
logger.info("===================== Connecting to Redis 3 =====================");
logger.info(Arrays.toString(nodes));
final RedisSentinelConfiguration SENTINEL_CONFIG = new RedisSentinelConfiguration().master(redisMasterName).sentinel(redisMasterNode, redisSentinelPort);
SENTINEL_CONFIG.setPassword(redisPassword);
for (String node : nodes) {
SENTINEL_CONFIG.sentinel(node, redisSentinelPort);
}
return SENTINEL_CONFIG;
}
}
Code (RedisTemplate) -
#Bean
public RedisTemplate<Object, Object> redisTemplate(JedisConnectionFactory cf) {
RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<Object, Object>();
redisTemplate.setConnectionFactory(cf);
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setDefaultSerializer(new GenericJackson2JsonRedisSerializer());
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
redisTemplate.setHashKeySerializer(new StringRedisSerializer());
redisTemplate.setKeySerializer(new GenericToStringSerializer<Long>(Long.class));
return redisTemplate;
}

You are trying to use Jedis 4.x with Spring boot 2.x.
It could be a difficult job to use Jedis 4.x with Spring boot 2.x.
There are some users who are using Jedis 4 but this is possible IFF you are not using some certain features and are willing to go through some extra works.
Until Spring releases support for Jedis 4, you may consider sticking to Jedis 3.x.
