Contents of the Applicationcontext.xml configuration file

Summary of steps:

1. Build a dependent jar

Spring must jar (6)

Hibernate must jar

Integration requires at least 3 jar,spring-jdbc.x.x to be imported, spring-tx.x.x,spring-orm.x.x

2. The goal is to create a sessionfactory

Manage Localsessionfactorybean to the spring IOC container

<bean class= "Org.springframework.orm.hibernate4.LocalSessionFactoryBean" ></bean>

3. Configuration of basic properties for hibernate

. hibernate.connection.driver_class

. Hibernate.connection.url. Hibernate.connection.username

. Hibernate.connection.password

. hibernate.dialect

. Hibernate.current_session_context_class. Hibernate.show_sql

. hibernate.format_sql

4. Scan the package for the entity class

Packagestoscan

5. Annotation Configuration for entity classes

6. Inject sessionfactory into the DAO layer

7. Create a Session object through Sessionfactory for database operation
