Using the Java Persistence API (JPA) with Spring 2.0

摘要

The EJB 3.0 Java Persistence API (JPA) was released in May 2006 as part of the Java Enterprise Edition 5 (Java EE) platform, and it has already garnered a great deal of attention and praise. What began as merely an easier-to-use successor to the much-maligned container-managed persistence (CMP) portion of the EJB component standard soon evolved into a full-blown incorporation of the existing best practices of the most prominent and popular object-relational (O-R) persistence products in use. The result is that applications now have a modern standard for lightweight enterprise Java persistence that they can use in any compliant Java EE 5 application server, or in Java Standard Edition (SE) applications.
