Issue with #ConfigurationProperties while using spring-session with Redis - redis

Question

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
#Component
#ConfigurationProperties(prefix = "app.redis")
#Validated
public class RedisSentinelProperties {
#NotNull
private String masterName;
#Valid
private Sentinel sentinel = new Sentinel();
////removed the getter and setter method for better readability
public static class Sentinel {
#NotEmpty
private List<String> nodes = new ArrayList<>();
//removed the getter and setter method for better readability
}
}
application.properties
app.redis.master-name=mymaster
app.redis.sentinel.nodes=192.168.56.50:26379,192.168.56.50:26380,192.168.56.50:26381
spring-session configuration
#SpringBootApplication
public class ConfigPropertiesDemoApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigPropertiesDemoApplication.class, args);
}
}
public class RedisHttpSessionInitializer extends AbstractHttpSessionApplicationInitializer {
public RedisHttpSessionInitializer() {
super(RedisHttpSessionConfig.class);
}
}
#Configuration
#EnableRedisHttpSession
#EnableWebSecurity
public class RedisHttpSessionConfig {
#Autowired
private RedisSentinelProperties redisSentinelProperties;
LettuceClientConfiguration clientConfig = LettuceClientConfiguration.builder()
.readFrom(SLAVE_PREFERRED)
.build();
private Set<String> sentinelHostAndPorts(){
Set<String> nodes = redisSentinelProperties.getSentinel().getNodes().stream().collect(Collectors.toSet());
return nodes;
}
//This is where NullPointerException is thrown line 37 in the stack trace
RedisSentinelConfiguration sentinelConfig = new RedisSentinelConfiguration(redisSentinelProperties.getMasterName(), sentinelHostAndPorts());
#Bean
public LettuceConnectionFactory connectionFactory() {
return new LettuceConnectionFactory(sentinelConfig, clientConfig);
}
}
Below is the stack trace
