My spring boot project uses spring-boot-starter-data-redis for caching on redis, Oracle database for persistent. It runs perfectly with current version 2.7.6. I've just upgraded to 3.0.5. The source code does change pretty much but this configuration for redis stays the same:
@Bean public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) { return RedisCacheManager.builder(redisConnectionFactory) .transactionAware() .build(); }Here is how I use @Cacheable
@Autowired private ConfRepository confRepository; @Cacheable(value = "configCache", key = "{#root.methodName, #key}") @Override public Optional<Config> getByKey(String key) { return confRepository.findByKey(key); }I deploy my service with 2 instances. The problem is when a key is put to Cacheable in instance 1 cannot be deserialized by instance 2, i.e in above method, my first request to instance 1 to getByKey with the key key1, my second request to instance 2 also with the key1 should hit the cache (get value from redis and return), but I got the stack trace:
