Java Persistence with Hibernate is the new bible of Hibernate. As a major revision of the popular Hibernate in Action, it builds on the same single example application to introduce and explain the latest Hibernate 3.2 in detail. In addition, the new and significantly improved EJB 3.0 Java Persistence standard, and how Hibernate implements it, is covered completely. All possible basic and advanced Hibernate mappings are shown in this book, with hundreds of examples in Hibernate's XML format, including Java Persistence annotations for JDK 5.0. Readers can get started with Hibernate and Java Persistence at the same time. All examples - APIs, queries, fetching strategies, caching, transactions, conversations, and many more - are presented in all variations, so they can compare and evaluate the new Java Persistence specification easily. If you are an experienced Hibernate user, this book provides the insight you need to benefit immediately from the new standard, its rich programming model, and the latest version of Hibernate.

Hibernate practically exploded onto the Java scene. Why? Because with it developers avoid a dreaded problem: object/relational mapping (ORM). There's a mismatch between your object-oriented code and the relational database you use. This object/relational mismatch requires you to write persistence code that maps one to the other, code which is often complex, tedious and costly to develop. Hibernate does it for you. But not only that, Hibernate makes persistence easy. Positioned as a layer between your application and your database, Hibernate takes care of loading and saving of objects. Hibernate apps are cheaper, more portable, and more resilient to change. And they perform better than anything you are likely to develop yourself. "Hibernate in Action" carefully explains the concepts you need, then gets you started quickly. Using a single, continuing example, it shows you how to use Hibernate in practice, how to deal with concurrency and transactions, how to efficiently retrieve objects and use caching. The authors developed Hibernate. They answered many community questions. Their experience seeps out of every pore of this book.

本书全面讲述了hibernate和java persistence，并对两者进行了详细的对比分析。书中通过一个应用将数百个例子融合起来，不仅深入剖析了hibernate 3.2和java persistence丰富的编程模型，还深刻阐述了数据库设计、对象/关系映射（orm）和优化等方面的基本原则、策略和最佳实践。书中处处闪烁着作者超凡的真知灼见，将大大升华读者对orm乃至企业级应用开发的理解。
本书适合广大的开发人员，从orm的初学者到经验丰富的开发人员。
