Not able to access the properties while using Spring-session with Redis. Auto wiring is not happening hence this object is null. Not sure what wrong I'm doing here.
@Autowired private RedisSentinelProperties redisSentinelProperties;
Without spring-session it works fine without any issue.
I have tried without spring-session and it works fine. Able to access the all the properties and Auto wiring happens properly
@Autowired private RedisSentinelProperties redisSentinelProperties;
Custom properties configuration
