Chapter 5. Hibernate Cache
In this chapter, we will discuss various topics on Hibernate caching. One of the advantages of using Hibernate is its ability to cache entities to minimize trips to the database. Of course, to take advantage of this feature correctly, one must be fully aware of the pitfalls.
