Statement:1, this article is original, not copied or reproduced over.2, this thesis has done the experimental demonstration.3. The hibernate configuration described in this article is based on annotations, and the HBM syntax is not available.A lot of people are not clear about the persistence layer concept JPA, Hibernate, EJB3.0 relationship, here to do a simple explanation: JPA is a persistent layer design

Http://blog.csdn.net/chjttony/article/details/6042138 1. hibernate is now the most popular open-source object relational ing (ORM) Persistence framework. The SSH framework combination is the first choice for many Java EE projects. The designer of Java persistence framework (JPA) is the author of hibernate, therefore, some basic knowledge of Hibernate is summarize

Get (), load (), and hibernate in hibernateThe session first checks whether the object exists. If the object exists, it cannot be retrieved in the database tutorial. The returned objects are all in the session cache. After modifying the attributes of the persistence object, when the session clears the cache, the database will be updated synchronously based on the attribute changes of the persistence object.Differences:(1) when there is no record corre

Software project Management If you are suddenly promoted to the project manager and you have no project management experience, you will be in the bottom of your mind, and if you feel that you manage the project poorly and would like to improve your project management skills, then it must be far water and thirst to test PMP

First,Hibernate cache Introduction :The session interface is the primary interface that hibernate provides to the application to manipulate the data interface, which provides basic methods for saving, updating, deleting, and loading Java objects.The session has a cache, the object in the cache is called a persisted object, and the session is able to update the database synchronously at some point in time, w

So The hibernate framework is an ORM framework.

HibernateHibernate is an open source object-relational mapping framework that provides JDBC with a very lightweight object encapsulation that maps Pojo to database tables, is a fully automated ORM framework, and Hibernate automatically generates SQL statements, automatically executes, So that Java programmers can use object programming thinking to manipulate the database at will.Language Features Simplifies development by translating operatio

Hibernate introduction, hibernate 1. What is Hibernate? Hibernate is an open-source object relationship ing framework that encapsulates JDBC objects in a lightweight manner, so that Java programmers can use the object programming thinking to manipulate the database as they wish. Programmers often only need to define t

XML "map document" that tells hibernate the classes you want to be able to save in the database and how they relate to the tables and columns in that database, and then you can ask it to get the data as an object, or to save the object as data. It's almost perfect compared to other solutions. 　　 Since this article is an introductory article, it will not introduce concrete examples of building and using Hibernat
