Bootstrap 2. Hibernate 5 Java Configuration Example - In this article, we will show you how to create a Hibernate Application using Java configuration without using hibernate. This article describes all cascade types with an example. Hibernate Database Operations Session Methods Hibernate 5 - Save an Entity Example - In this article, we will create a simple Hibernate application to demonstrate how to save an entity into a database. Hibernate 5 - Persist an Entity Example - In this article, we will create a simple Hibernate application to demonstrate how to persist an entity into a database. Hibernate 5 - saveOrUpdate Method Example - In this article, we will create a simple Hibernate application to demonstrate how to save or update an entity in the database using the saveOrUpdate method. Hibernate 5 - get , load and byId Method Examples - In this article, we will show you how to use Session.
We can configure it using XML, property files as well as programmatically. This tutorial is a great way to get you started with hibernate framework. This tutorial focuses on different configurations required for hibernate and provide examples of simple XML based mapping as well as JPA annotations based mapping.
You will also learn different ways to initialize SessionFactory and important components of the hibernate framework. Hibernate One-to-One Mapping Most of the times, database tables are associated with each other. There are many forms of association — one-to-one, one-to-many and many-to-many are at the broad level, that can be further divided into unidirectional and bidirectional mappings.
Hibernate One-to-Many Mapping In simple terms, one to many mapping means that one row in a table can be mapped to multiple rows in another table. For example, think of a Cart system where we have another table for Items.
A cart can have multiple items, so here we have one to many mapping. Every cart can have multiple items and every item can be part of multiple carts, so we have a many to many mapping here. This tutorial explains about hibernate many-to-many unidirectional as well as bidirectional mapping.
All requests from the Session object to the database must pass through the first-level cache or session cache. One must note that the first-level cache is available with the session object until the Session object is live. Transaction : enables you to achieve data consistency, and rollback incase something goes unexpected.
Persistent objects : These are plain old Java objects POJOs , which get persisted as one of the rows in the related table in the database by hibernate. They can be configured in configurations files hibernate. Second-level cache : It is used to store objects across sessions. This needs to be explicitly enabled and one would be required to provide the cache provider for a second-level cache.
One of the common second-level cache providers is EhCache. As a result, business logic is able to access and manipulate database entities via Java objects. It helps to speed up the overall development process by taking care of aspects such as transaction management, automatic primary key generation, managing database connections and related implementations, and so on. JPA is a set of specifications for accessing, persisting, and managing data between Java objects and relational database entities.
Idiomatic persistence Any class that follows object-oriented principles such as inheritance, polymorphism, and so on, can be used as a persistent class. High performance and scalability Hibernate supports techniques such as different fetching strategies, lazy initialization, optimistic locking, and so on, to achieve high performance, and it scales well in any environment.
Easy to maintain Hibernate is easier to maintain as it requires no special database tables or fields.
It generates SQL at system initialization time. It is much quicker and easier to maintain compared to JDBC.
