In this chapter, we discuss the life cycle of persistent objects in Hibernate. These persistent objects can be POJOs without any special marker interfaces or inheritance related to Hibernate. Part of Hibernate's popularity comes from its ability to work with a normal object model....
(2)Life cycle dependencies—If a User is deleted, its Address dependency has to bedeleted as well. (3)Identity—Entity classes need an identifier property in almost all cases. Value typeclasses (and of course JDK classes such as String and Integer ) don’t have anidentifier property, becaus...
The Java Persistence API (JPA) is the standard for using persistence in Java projects. Java EE 6 applications use the Java Persistence 2.0 specification, documented here: http://www.jcp.org/en/jsr/detail?id=317. Hibernate EntityManager implements the programming interfaces and life-cycle rules de...
The value specified for the cascade element in the annotation specifies that life-cycle operations on the Customer entity must be cascaded to the Address entity, the target of the relationship. In other words, when a Customer instance is made persistent, any Address instances related to the ...
Imagine having a tool that can automatically detect if you are using JPA and Hibernate properly. No more performance issues, no more having to spend countless hours trying to figure out why your application is barely crawling. Imagine discovering early during the development cycle that you are usi...

Hibernate学习之四---The Persistence Life Cycle 1. Life Cycle Given an instance of an object that is mapped to Hibernate, it can be in any one of three different states: transient, persistent, or detached. 映射到Hibernate中的类可以是以下三种状态中的一种:瞬时的,持久的...resin下...
Fortunately, viraemia in humans and horses is probably insufficient to infect mosquitoes, and they are considered to be dead-end hosts2. In the past, the temperate northern Japanese Island Hokkaido was affected by JEV epidemics, and the virus was shown to hibernate and re-emerge in the same ...
