6. Working with Database
ORM
class Student
{
String name;
String college;
}
ORM Approach
Obj
name college

7. How to work with Spring ORM
• Using HibernateTemplate class
■ Methods for accessing database
● save
● update
● insert
● get
● loadAll
● etc. (N number methods)
■ So we need object of HibernateTemplate class to call
methods, but creating object of HibernateTemplate
class is not easy.

8. Creating object of HibernateTemplate
In our Dao class
CustomerDao HibernateTemplat
e
SessionFactory
LocalSession
FactoryBean
DataSource

9. Student Record Project Structure
CustomerDao
(Database Access)
App
(Main Class)
Customer
(Model/Entity)
config.xml
(bean creation)
pom.xml
(dependency)

10. Steps to do CRUD operations
• Create Maven Project
• Add dependencies in pom.xml → provided by us
■ spring-core
■ spring-context
■ mysql-connector-java
■ spring-orm
■ hibernate-core
■ junit (by default)

11. Steps to do CRUD operations
• Create class Customer → Model/Entity/Table Mapping
(Get,Set,Constructor)
• Create class CustomerDao → Data Access using HibernateTemplate
■ Create object of HibernateTemplate
○ HibernateTemplate hibernateTemplate;
■ Insert Data - create own method
○ hibernateTemplate.save(custObj);
■ Select Data → Single Record - create own method
○ hibernateTemplate.get(Customer.class, custId);

12. Steps to do CRUD operations
■ Delete Data - create own method → select data record
○ hibernateTemplate.delete(custObj);
■ Select Data → All Record - create own method
○ hibernateTemplate.loadAll(Customer.class);
■ Update Data - create own method → select data record
○ hibernateTemplate.update(custObj);

13. Steps to do CRUD operations
• Create main class App
• Create config.xml → copy data provided by us
■ Change data as per comments given in file
• Create database as per name given to datasource in config file

14. Questions ?
The purpose of software engineering is to control complexity,
not to create it.
