This is a snippet of my configuration class
@Configuration@EnableCachingpublic class RedisCacheConfig extends CachingConfigurerSupport {@Beanpublic LettuceConnectionFactory redisConnectionFactory() { return new LettuceConnectionFactory(new RedisStandaloneConfiguration(), LettuceClientConfiguration.builder() .commandTimeout(Duration.ofMillis(1000)) .build());}@Beanpublic RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory connectionFactory) { RedisTemplate<Object, Object> template = new RedisTemplate<>(); template.setConnectionFactory(connectionFactory); return template;}//Cache manager configurations follow here...When the local redis server is up the app works flawlessly but when the redis is down the startup fails with the following:
org.springframework.data.redis.RedisConnectionFailureException: Unableto connect to Redis; nested exception isio.lettuce.core.RedisConnectionException: Unable to connect tolocalhost:6379 atorg.springframework.data.redis.connection.lettuce.LettuceConnectionFactory$ExceptionTranslatingConnectionProvider.translateException(LettuceConnectionFactory.java:1689)atorg.springframework.data.redis.connection.lettuce.LettuceConnectionFactory$ExceptionTranslatingConnectionProvider.getConnection(LettuceConnectionFactory.java:1597)at

When the cache server is down I would like the app to go on and just run as if there was no caching used all. Any try/catch solutions that I found in other questions did not do the trick. Any ideas?
