Hibernate meets Java

摘要

An object-centric application is easy to develop and highly portable across platforms and databases. An object-relational mapper is a framework used to transform an object view of the data into a relational one, and provide persistence services. Here, we'll walk through some simple Hibernate code snippets, and show you how to persist a POJO-Bean, a part of our MedTracker application, with Hibernate. We'll create a standalone console-based Hibernate application. We'll use MySQL DB, and, MySQL connector for Java to connect to the database.
