this is my first question so pardon me if the way I phrase the questions still need improvement
I am currently working on a Spring Boot Web Application which uses Redis as a Cache to prevent excessive calls to external APIs. In that sense, Spring is actually good to have but not a necessity.
1.) A persistence module containings DAO classes that compiles spring-data-redis project and uses RedisTemplate with @Autowired annotation
Example RedisDao class(I am not using the exact implementation due to private code reasons):
@Autowired
private RedisTemplate redisTemplate
public AuthInfoDto createAuthInfo(Integer memberId, Integer expiry) {
//Some method to generate key
String key = createAuthKey(memberId)
redisTemplate.opsForValue().set(key, memberId)
}
This project is then built with gradle clean install to generate the jar file to be imported by main project
2.) The main project then compiles the persistence project and I set up configuration in this main project
@Configuration
@Lazy
public class RedisConfigure {
@Bean
@Lazy
public RedisTemplate<String, Integer> redisTemplate(JedisConnectionFactory jedisConnectionFactory) {
RedisTemplate<String, Integer> redisTemplate = new RedisTemplate<>();
redisTemplate.setConnectionFactory(jedisConnectionFactory)
redisTemplate.setKeySerializer(new StringRedisSerializer());
redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
return redisTemplate;
}
}
The problem is that; when Sentinel is not available or there's a connection error to Sentinel. The Spring Boot application cannot start
I have tried adding @Lazy annotations to all the beans and configuration files including that in the persistence module but its still not working.
Something I notice is that JedisConnectionFactory automatically throws an exception if it cannot detect any Sentinel during startup.
May I know if there are any ways I can prevent spring boot from trying to connect to Sentinel during startup?
Thank you very much
EDIT Here is the error code. As for JedisConnectionFactory Bean; I let spring-data-redis auto configuration handle it for me so i just set the required properties in my application.yml file

The exception you're seeing comes from JedisConnectionFactory.afterPropertiesSet(). You need to set all Redis-related beans to @Lazy, also the connection factory.
You would need to declare your own JedisConnectionFactory bean. Alternatively, try using the Lettuce driver as Lettuce attempts to resolve a Redis server rather lazily.
