Note that the character ' ' is the statement terminator for every command. After installing the database, start the MySql client and create a test database by issuing the following command,
The following sample application uses the MySql database for dealing with data. The following sections cover the various steps involved in the Spring-Hiberante integration along with a detailed explanation. Instead of looking into the various Integration APIs that are available in the Spring Bundle, let us study and understand these APIs as we go through the sample code. It means that now it is possible to use the Hibernate objects as Spring Beans and they can enjoy all the facilities that Spring provides. In simple words, the state of an object can be externalized from the Application code. In the case of Spring, the business objects can be highly configurable with the help of IOC Container.

Moreover, the Application code has to manually maintain and manage these objects.
These objects will continue to get scattered across the code throughout the Application. One of the problem with using Hibernate is that the client Application that accesses the database using Hibernate Framework has to depend on the Hibernate APIs like Configuration, SessionFactory and Session.
Another good thing is that Hibernate can be coupled well with both J2SE and J2EE Applications. All the necessary details for accessing a particular data source is easily configurable in Xml files. There is no need for the Application to depend on the low-level JDBC details like managing connection, dealing with statements and result sets. It enables Application to access data from any database in a platform-independent manner. It is well known that Hibernate is a powerful ORM tool that lies between Application and Database.

In another article Introduction to Hibernate explains what is ORM framework and how to start writing the simple hibernate application.Īlso read: follow us on Spring Interview QuestionsĪs a pre-requisite, let us understand the need for such integration before we actually get into the integration between these two technologies. This article will help you to understand the fundamentals of the Spring framework. If you are new to Spring and Hibernate frameworks, please read the introduction articles on Spring and Hibernate before start reading this article Introduction to Spring Framework. This article assumes that the reader has a basic understanding in both Spring and Hibernate Frameworks. In this article, we will discuss on how it is possible to integrate Spring with Hibernate. The beauty of Spring is that it can integrates well with most of the prevailing popular technologies. Spring, on the other hand is a dependency injection framework that supports IOC.
It is a programming technique for converting data between incompatible type systems like relational databases and object oriented programming languages like java.Hibernate is a powerful technology for persisting data in any kind of Application. ORM refers to the Object-Relational Mapping. This creates a mismatch between the object model and the relational database. Java follows the object model and represents the data in the form of interconnected graph of objects whereas relational database represents the data in the tabular form. As we discussed JDBC provides a way for Java programs to communicate with the relational database.
