  Slide 3 www.edureka.co/persistence-with-hibernate AnObject relational mapping library of java language for Object persistence and SQL databases Found in 2001 by Gavin King Transparent persistence of java objects with relational database Provides query language in synch with SQL Open source library Provides solutions for object relational impedance mismatch problems Hibernate

  Slide 4 www.edureka.co/persistence-with-hibernate Providesa simple API for storing and retrieving Java objects directly to and from the database Non-intrusive: No need to follow specific rules or design patterns Transparent: Your object model is unaware Persistence using Hibernate JavaObject int id; String name; String getName() int getId() void setName(String) SQL Table id [int] primary key, name [varchar(50)], Magic Happens Here (O/R Mapper – i.e. Hibernate)

  Slide 5Slide 5Slide5 www.edureka.co/persistence-with-hibernate Spring An open source framework Enables to build applications using POJO (Plain Old Java Objects) Handles the complete infrastructure required for application from end to end Makes development of JavaEE (Java EnterPrise Applications) easier Light weight and transparent Use of IOC Containers Supports ORM and Transaction Management
• 6.
  Slide 6Slide 6Slide6 www.edureka.co/persistence-with-hibernate Spring with Hibernate An extensive support for ORM frameworks like Hibernate , JPA Provides complete infrastructure for any ORM layer used in the application  IOC of spring handles the SessionFactory instances of hibernate Configurations of hibernate are taken care efficiently by spring application contexts Use of hibernate.cfg.xml can be taken care by spring applicationContext.xml Declarative Transaction management Built in support for exception handling
• 7.
  Slide 7Slide 7Slide7 www.edureka.co/persistence-with-hibernate Spring supports two different approach for transaction management: Programmatic Transaction Management » Transactions are managed by programming codes » Highly flexible » Difficult in maintenance » Spring TransactionTemplate is used for programmatic approach Declarative Transaction Management » Transactions are handled declaratively by XML or Annotation » Will have lesser impact with the code of application » Extensive support from Spring AOP » Most widely used Transaction Management with Spring

  Slide 8Slide 8Slide8 www.edureka.co/persistence-with-hibernate Spring Aspect Oriented Programming enables to declare transaction declaratively with Aspect Aspect scatters across methods, class and even objects Can be used in xml and annotations AOP declarative transaction:- » Transaction-handling advice is created using <tx:advice/> and pointcut is defined to make transactional advice that matches all methods » Advice begins transaction on before calling the method » On successful execution of method advice commits the transaction » On failure advice rolls back Spring AOP Transaction Management <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="create"/> </tx:attributes> </tx:advice> <aop:config> <aop:pointcut id="createOperation" expression="execution(* com.tutorialspoint.StudentJDBCTemplate.create (..))"/> <aop:advisor advice-ref="txAdvice" pointcut- ref="createOperation"/> </aop:config>

  Slide 14 www.edureka.co/persistence-with-hibernate Inthe applicationContext.xml file we are declaring lots of bean definition One is for DataSource definition, one is for Hibernate Session Factory with the mapping resource course.hbm.xml Then we are creating HibernateTemplate bean setting its sessionFactory property to mysessionfactory Last is the bean definition of CourseDAO class setting its template property to HibernateTemplate bean Spring and Hibernate Example (Contd.)
