Overview of this book

Hibernate has been so successful since its inception that it even influenced the Java Enterprise Edition specification in that the Java Persistence API was dramatically changed to do it the Hibernate way. Hibernate is the tool that solves the complex problem of Object Relational Mapping. It can be used in both Java Enterprise applications as well as .Net applications. Additionally, it can be used for both SQL and NoSQL data stores. Some developers learn the basics of Hibernate and hit the ground quickly. But when demands go beyond the basics, they take a reactive approach instead of learning the fundamentals and core concepts. However, the secret to success for any good developer is knowing and understanding the tools at your disposal. It’s time to learn about your tool to use it better This book first explores the internals of Hibernate by discussing what occurs inside a Hibernate session and how Entities are managed. Then, we cover core topics such as mapping, querying, caching, and we demonstrate how to use a wide range of very useful annotations. Additionally, you will learn how to create event listeners or interceptors utilizing the improved architecture in the latest version of Hibernate.

Summary


In this chapter, we discussed the statistics and metrics that Hibernate can collect. We showed how you can configure Hibernate to start collecting this data and how we can get access to this data. This included datasets at the session factory level (for all sessions), including entity, collection, query, and cache metrics. Furthermore, we showed that you can collect statistics for a named entity or query.

We completed this chapter by introducing JMX and showing you how it can be used to monitor the Hibernate statistical data at runtime using a remote client such as jconsole. We further showed how to utilized Spring for easy integration.

In the next chapter, we'll explore architectural concerns related to enterprise applications and how Hibernate can address these concerns.
