Object Relational Mapping (ORM) with Spring by R4R Team

Object Relational Mapping (ORM) with Spring:-
The Spring Framework supports integration with Hibernate, Java Persistence API (JPA) and Java Data Objects (JDO) for resource management, data access object (DAO) implementations, and transaction strategies. For example, for Hibernate there is first-class support with several convenient IoC features that address many typical Hibernate integration issues. You can configure all of the supported features for O/R (object relational) mapping tools through Dependency Injection. They can participate in Spring’s resource and transaction management, and they comply with Spring’s generic transaction and DAO exception hierarchies. The recommended integration style is to code DAOs against plain Hibernate, JPA, and JDO APIs.

Spring adds significant enhancements to the ORM layer of your choice when you create data access applications. You can leverage as much of the integration support as you wish, and you should compare this integration effort with the cost and risk of building a similar infrastructure in-house. You can use much of the ORM support as you would a library, regardless of technology, because everything is designed as a set of reusable JavaBeans. ORM in a Spring IoC container facilitates configuration and deployment.

Advantage of ORM Frameworks with Spring:-
There are a lot of advantage of Spring framework in respect to ORM frameworks. There are as follows:
1 Less coding is required: By the help of Spring framework, you don't need to write extra codes before and after the actual database logic such as getting the connection, starting transaction, commiting transaction, closing connection etc.
2 Easy to test: Spring's IoC approach makes it easy to test the application.
3 Better exception handling: Spring framework provides its own API for exception handling with ORM framework.
4 Integrated transaction management: By the help of Spring framework, we can wrap our mapping code with an explicit template wrapper class or AOP style method interceptor.
