Spring Data JPA or spring hibernate which do i need to learn RN

from the above which should i learn or do I need to learn both then in which order im new to spring framework (about few days )

Solution
    1. Hibernate is a JPA (specification) implementation.
    2. A good way to learn Hibernate is to read the book "[Java Persistence in Action][1]" by Manning. It has 400 pages but teaches you everything there is to know.
    3. Spring Data JPA builds ON TOP of Hibernate/JPA.
    4. If you don't know Hibernate, you WILL get lost sooner or later with Spring Data, even if it makes things easier at the beginning for you.
