I wanted to fetch cached(@Cachable) value using redisson client but it throws error.
i have used below code for caching
@Cacheable(value = "fruits", key = "#id") public Fruit getFruitById(int id) { // get fruit by id CriteriaBuilder builder = em.getCriteriaBuilder(); CriteriaQuery<Fruit> query = builder.createQuery(Fruit.class); Root<Fruit> root = query.from(Fruit.class); query.select(root); query.where(builder.equal(root.get("id"), id)); TypedQuery<Fruit> fruitQuery = em.createQuery(query); return fruitQuery.getSingleResult();}i've used below code fetching that cached data
RBucket<Fruit> bucket = client.getBucket("fruits::1"); Fruit fruit = bucket.get();even though data exist for that key(fruit::1) it throws below error
