Spring MVC - Hibernate Demo Application
Hello Friends,
Nice to see you again.
In Previous Sessions we have seen Spring MVC with Annotation Demo. And learn how they work.
Today, we will see the example of
Spring MVC with Hibernate basic tutorial.
This demo I have created using Netbeans IDE 7.1.2.
Netbeans provide Spring Project with Hibernate, So no need to find out every Jars as it provides by Netbeans itself.
Ok Here we will create one
Student Register Application demo which we previosuly develope without database.
Now we will extend that with adding Hibernate support to persist our data in MySQL Server.
Below is our final output.
 |
| Student Registration Demo |
For create this application, I have create one Database Table "Student" in MySQL Server as below.
---------------------------------------------------------------------------------------------------------------------------
CREATE TABLE `student` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`firstname` varchar(30) DEFAULT NULL,
`lastname` varchar(30) DEFAULT NULL,
`telephone` varchar(15) DEFAULT NULL,
`email` varchar(30) DEFAULT NULL,
`created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=latin1
