Example to create the Hibernate Application in Eclipse IDE
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:
1) Create the java project
2) Add jar files for hibernate
download the required jar file
In this example, we are connecting the application with oracle database. So you must add the ojdbc14.jar file.
download the ojdbc14.jar file
3) Create the Persistent class
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.javatpoint.mypackage) - finish.
4) Create the mapping file for Persistent class
Here, we are creating the same mapping file as created in the previous topic. To create the mapping file, Right click on src - new - file - specify the file name (e.g. employee.hbm.xml) - ok. It must be outside the package.
5) Create the Configuration file
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.
6) Create the class that retrieves or stores the persistent object
In this class, we are simply storing the employee object to the database.
7) Run the application
Note: You need to connect with the internet to run this example.
