Convenient super class for JPA data access objects. Intended for JpaTemplate usage. Alternatively, JPA-based DAOs can be coded against the plain JPA EntityManagerFactory/EntityManager API.
Requires an EntityManagerFactory or EntityManager to be set, providing a JpaTemplate based on it to subclasses. Can alternatively be initialized directly via a JpaTemplate, to reuse the latter's settings such as the EntityManagerFactory, JpaDialect, flush mode, etc.
This class will create its own JpaTemplate if an EntityManagerFactory
or EntityManager reference is passed in. A custom JpaTemplate instance
can be used through overriding createJpaTemplate
.

Create a JpaTemplate for the given EntityManager. Only invoked if populating the DAO with a EntityManager reference!
Can be overridden in subclasses to provide a JpaTemplate instance with different configuration, or a custom JpaTemplate subclass.
