Hibernate not only takes care of the mapping from Java classes to database This tutorial will teach you how to use Hibernate to develop your database based . Hibernate Tutorial & Learning PDF guides. This Section describes about the basics of Hibernate that will help a beginner to learn about this technology. Here we. Explanations with complete working examples Whenever something is explained you will find a complete sample application. If a specific mapping is.

Our persistence logic is dependent because of using JDBC. Here we are inserting a record into Employee table but our query is Database software dependent i. Here we are using MySQL. But if we change our Database then this query wont work. JDBC code is not portable code across the multiple database softwares. Here We can see that we are handling lots of Exception for connection. For each and every project we have to write the below code. That increases the code length and reduce the readability. To overcome from the above problems we use ORM tool i. By using Hibernate we can avoid all the above problems and we can enjoy some additional set of functionalities. About Hibernate Framework Hibernate is a framework which provides some abstraction layer means programmer dont have to worry about the implementations, Hibernate do implementations for you internally like Establishing a connection with the database, writing query to perform CRUD operations etc. It is a java framework which is used to develop persistence logic. Persistence logic means to store and process the data for long use. More precisely Hibernate is a open source, non-invasive, light-weight java ORM Object relational mapping framework to develop objects which is independent of the database software and make independent persistence logic in all JAVA, JEE.

Framework means it is a special install-able software that provides abstraction layer on one or more technologies like JDBC,Servlet etc to simplify or reduce the complexity for development process. Open Source means: Hibernate framework is available for everyone without any cost.

The source code of Hibernate is also available on the Internet and we can also modify the code. Light-weight means: Hibernate is less in size means the installation package is not big is size. Hibernate does not require any heavy container for execution.

Hibernate is one of the best Java ORM tool in the current market. So this post is like an index of all the posts for hibernate tutorials and examples.

You can go through these hibernate tutorials in sequence to learn hibernate from scratch. Most probably I will be adding more hibernate tutorials to the list, so you might want to bookmark it and check it once in a while.

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.

Introduction to Hibernate Framework

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. Hibernate Criteria Hibernate provides Criteria API that is more object oriented for querying the database and getting results.

Some of the common usage of Criteria API are Projection that we can use for aggregate functions such as sum , min , max etc, ProjectionList to fetch selected columns only, ordering the results etc.

Hibernate First Level Cache Hibernate Cache can be very useful in gaining fast application performance if used correctly. The idea behind cache is to reduce the number of database queries, hence reducing the throughput time of the application. Hibernate first level cache is associated with the Session object. Hibernate first level cache is enabled by default and there is no way to disable it.

However hibernate provides methods through which we can delete selected objects from the cache or clear the cache completely. Any object cached in a session will not be visible to other sessions and when the session is closed, all the cached objects will also be lost.

Hibernate Tutorial

This tutorial provides a complete example to integrate EHCache with Hibernate framework. Hibernate get vs load Hibernate Session provide different methods to fetch data from database. Two of them are — get and load.

There are also a lot of overloaded methods for these, that we can use in different circumstances. At first look both get and load seems similar because both of them fetch the data from database. However there are few differences between them, this tutorial explains about them with example code.
