Your entity is @Cacheable, your cache is configured properly, but still, loading an entity produces a lot of sql queries. I noticed that the other day, and realized something: hibernate does not cache collection mappings. So if you have @OneToMany, they are fetched from the database. Which is a bit counter-intuitive, because my assumption was that hibernate caches the whole entity. This article explains what happens.
