org.springframework.orm.jpa .JpaOperations

All known Subclasses:   org.springframework.orm.jpa .JpaTemplate,
JpaOperations
public interface JpaOperations (Code)
Interface that specifies a basic set of JPA operations, implemented by JpaTemplate . Not often used, but a useful option to enhance testability, as it can easily be mocked or stubbed.
Defines JpaTemplate's data access methods that mirror various javax.persistence.EntityManager methods. Users are strongly encouraged to read the JPA EntityManager javadocs for details on the semantics of those methods.
Note that lazy loading will just work with an open JPA EntityManager, either within a managed transaction or within org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter / org.springframework.orm.jpa.support.OpenEntityManagerInViewInterceptor . Furthermore, some operations just make sense within transactions, for example: flush, clear.
