Here is an elegant solution to solve your issue :

@Configuration
@PropertySource(name="application", value="classpath:application.properties")
public class SpringSessionRedisConfiguration {

    @Resource
    ConfigurableEnvironment environment;

    @Bean
    public PropertiesPropertySource propertySource() {
        return (PropertiesPropertySource) environment.getPropertySources().get("application");
    }

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        return new JedisConnectionFactory(sentinelConfiguration(), poolConfiguration());
    }

    @Bean
    public RedisSentinelConfiguration sentinelConfiguration() {
        return new RedisSentinelConfiguration(propertySource());
    }

    @Bean
    public JedisPoolConfig poolConfiguration() {
        JedisPoolConfiguration config = new JedisPoolConfiguration();
        // add your customized configuration if needed
        return config;
    }

    @Bean
    RedisTemplate redisTemplate() {
        RedisTemplate redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(jedisConnectionFactory());
        return redisTemplate;
    }

    @Bean
    RedisCacheManager cacheManager() {
        return new RedisCacheManager(redisTemplate());
    }

}

so, to resume :

• add a specific name for the @PropertySource
• inject a ConfigurableEnvironment instead of Environment
• get the PropertiesPropertySource in your ConfigurableEnvironment using the name you mentioned on your @PropertySource
• Use this PropertySource object to construct your RedisSentinelConfiguration object
• Don't forget to add 'spring.redis.sentinel.master' and 'spring.redis.sentinel.nodes' properties in you property file
