Hibernate Introduction

<div dir="ltr" style="text-align: left;" trbidi="on">
<b>Hibernate Framework</b><br />
<br />
<b></b>Hibernate framework simplifies the development of java application to interact with the database. Hibernate is an open source, lightweight, ORM (Object Relational Mapping) tool.<br />
<br />
 An ORM tool simplifies the data creation, data manipulation and data access. It is a programming technique that maps the object to the data stored in the database.
hibernate tutorial, An introduction to hibernate

The ORM tool internally uses the JDBC API to interact with the database.<br />
<br />
<b>Advantages of Hibernate Framework </b><br />

There are many advantages of Hibernate Framework. They are as follows:<br />
<br />
<b>1) Opensource and Lightweight: </b><br />
Hibernate framework is opensource under the LGPL license and lightweight.<br />
<br />
<b>2) Fast performance: </b><br />
The performance of hibernate framework is fast because cache is internally used in hibernate framework. There are two types of cache in hibernate framework first level cache and second level cache. First level cache is enabled bydefault.<br />
<br />
<b>3) Database Independent query</b>:<br />
 HQL (Hibernate Query Language) is the object-oriented version of SQL. It generates the database independent queries. So you don't need to write database specific queries. Before Hibernate, If database is changed for the project, we need to change the SQL query as well that leads to the maintenance problem.<br />
<br />
<b> 4) Automatic table creation: </b><br />
Hibernate framework provides the facility to create the tables of the database automatically. So there is no need to create tables in the database manually.<br />
<br />
<b> 5) Simplifies complex join:</b><br />
To fetch data form multiple tables is easy in hibernate framework.<br />
<br />
<b> 6) Provides query statistics and database status:</b><br />
<b></b>Hibernate supports Query cache and provide statistics about query and database status.<br />

What is lazy loading in Hibernate?

<div dir="ltr" style="text-align: left;" trbidi="on">
<span class="fullpost">Lazy setting decides <strong><u>whether to load child objects while loading the Parent</u></strong> Object.You need to do this setting respective hibernate mapping file of the parent class.<strong>lazy = true</strong> (<em>means not to load child</em>)By
 default the lazy loading of the child objects is true. This make sure 
that the child objects are not loaded unless they are explicitly invoked
 in the application by calling <strong>getChild()</strong> method on parent.In this case hibernate issues a fresh database call to load the child when <strong>getChild()</strong>
 is actully called on the Parent object.But in some cases you do need to
 load the child objects when parent is loaded. Just make the <strong>lazy=false</strong> and hibernate will load the child when parent is loaded from the database.<br />
                      <br />
                                <em>Example:</em> <strong>lazy=true</strong> (<em>default</em>)Address child of User class can be made lazy if it is not required frequently. <strong>lazy=false </strong>but you may need to load the Author object for Book parent whenever you deal with the book for online bookshop.<br />
<br />
Lazy fetching means for example in hibernate if we use <strong>load() </strong>method then <strong>load()</strong>
 is lazy fetching i.e it is not going to touch the database until we 
write empobject.getString( eno );So when we write above statement in 
that instance it touch the database and get all the data from database. 
It is called as <u>lazy loading</u>.If we see another example i.e session.<strong>get(...)</strong>
 method is used then at that instance it is going to touch the database 
and get the data and place the data in session object it is called as <u>eager loading</u>.</span><br />

<div style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;">
Hibernate Query Language (HQL) is same as SQL (Structured Query Language) but it doesn't depends on the table of the database. Instead of table name, we use class name in HQL. So it is database independent query language.</div>

Step by step tutorial to create the Hibernate Application in Eclipse IDE

<div dir="ltr" style="text-align: left;" trbidi="on">
<div style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;">
Here, we are going to create a simple example of hibernate application using eclipse IDE. For creating the first hibernate application in Eclipse IDE, we need to follow following steps:</div>
<ol style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;">
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Create the java project</li>
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Add jar files for hibernate</li>
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Create the Persistent class</li>
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Create the mapping file for Persistent class</li>
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Create the Configuration file</li>
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Create the class that retrieves or stores the persistent object</li>
<li style="font-family: Verdana; line-height: 1.5; margin-top: 3px;">Run the application</li>
</ol>
<h3 class="h3" style="background-color: white; color: green; font-family: erdana, helvetica, arial, sans-serif; font-size: 21px; font-weight: 400; padding: 0px 0px 0px 5px;">
1) Create the java project</h3>
<table style="background-color: white; color: black; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;"><tbody>
<tr><td style="line-height: 1.5; margin-left: 20px;">Create the java project by <strong>File Menu</strong> - <strong>New</strong> - <strong>project</strong> - <strong>java project </strong>. Now specify the project name e.g. firsthb then <strong>next </strong>- <strong>finish </strong>.</td></tr>
</tbody></table>
<hr style="background-color: #d4d4d4; border: 0px; clear: both; color: #d4d4d4; font-family: Verdana, Arial, sans-serif; font-size: 13px; height: 1px; line-height: 19.5px;" />
<h3 class="h3" style="background-color: white; color: green; font-family: erdana, helvetica, arial, sans-serif; font-size: 21px; font-weight: 400; padding: 0px 0px 0px 5px;">
2) Add jar files for hibernate</h3>
<table style="background-color: white; color: black; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;"><tbody>
<tr><td style="line-height: 1.5; margin-left: 20px;">To add the jar files <strong>Right click on your project</strong> - <strong>Build path</strong> - <strong>Add external archives</strong>. Now select all the jar files as shown in the image given below then click open.</td></tr>
</tbody></table>
<a href="https://www.blogger.com/null" id="step1" style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;"></a> <img alt="example to create hibernate application in Eclipse IDE" src="http://www.javatpoint.com/images/hibernate/addjar.jpg" style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;" /><span style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;"></span><br />
<div style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;">
In this example, we are connecting the application with oracle database. So you must add the ojdbc14.jar file.</div>

3) Create the Persistent class</h3>
<div style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;">
Here, we are creating the same persistent class which we have created in the previous topic. To create the persistent class, Right click on src - New - Class - specify the class with package name (e.g. com.mani.mypackage) - finish.</div>

5) Create the Configuration file</h3>
<div style="background-color: white; font-family: Verdana, Arial, sans-serif; font-size: 13px; line-height: 19.5px;">
The configuration file contains all the informations for the database such as connection_url, driver_class, username, password etc. The hbm2ddl.auto property is used to create the table in the database automatically. We will have in-depth learning about Dialect class in next topics. To create the configuration file, right click on src - new - file. Now specify the configuration file name e.g. hibernate.cfg.xml.</div>
