Springboot fail to start if Redis is down

Redis is optional in my application & this is one of the requirement that even if Redis is down, application MUST be able to start without any issue.
I was able to handle this with spring-data-redis 1.8.1 version but it's causing issue when I upgraded to 2.0.1.
I was able to catch exception thrown during LettuceConnectionFactory but now it's throwing exception & control is not returned to calling class.
Please let me know how can I make Redis bean instantiation optional so that application server starts without any issue even if Redis is down.

SpringRedisConfig.java

   @Configuration
    public class SpringRedisConfig{
        private static final Logger logger = LoggerFactory.getLogger(SpringRedisConfig.class);

        @Value("${redis.config.file.path}")
        private String redisConfigFilePath;

        @Value("${redis.timeout}")
        private long redisTimeOut;

        public @Bean RedisTemplate redisTemplate(){
            RedisTemplate<String, Object> redisTemplate = null;
            try {
                redisTemplate = new RedisTemplate<>();
                redisTemplate.setKeySerializer(new StringRedisSerializer());
                redisTemplate.setHashKeySerializer(new StringRedisSerializer());
                redisTemplate.setHashValueSerializer(new GenericToStringSerializer<>(Long.class));
                redisTemplate.setConnectionFactory(connectionFactory());
            }catch(Exception e){
                logger.error("Error getting Redis Template connection ",e);
            }
            return redisTemplate;
        }

        @Bean
        public LettuceConnectionFactory connectionFactory() {
            LettuceConnectionFactory connectionFactory = null;
            try {
                ClientOptions clientOptions = ClientOptions.builder()
                        .cancelCommandsOnReconnectFailure(true)
                        .disconnectedBehavior(ClientOptions.DisconnectedBehavior.REJECT_COMMANDS)
                        .build();
                RedisStandaloneConfiguration standaloneConfig = new RedisStandaloneConfiguration("localhost",
                        6379);
                LettuceClientConfiguration lettuceClientConfiguration = LettuceClientConfiguration.builder().clientOptions(clientOptions).build();
                connectionFactory = new LettuceConnectionFactory(standaloneConfig, lettuceClientConfiguration);
            }catch(Exception e){
                logger.error("Error ",e);
            }
            return connectionFactory;
        }
    }
