A hibernate is an object relational mapping (ORM) tool, that is used to manipulate database tables as class and their object.Today we will move forward and integrate Spring MVC and Hibernate frameworks in a web application CRUD example. Final versions for our example, same program is also compatible for Spring 4 and Hibernate 3, however you need to make small changes in spring bean configuration file discussed in the last tutorial. Below screenshots shows the view pages for our application.Our final project structure looks like below image, we will look into each of the components one by one. Let’s look at all the maven dependencies are required for hibernate and spring mvc framework integration. You will also find similar logs in the server log file. Person DAOImpl - Person saved successfully, Person Details=id=15, name=Pankaj, country=USA Hibernate: select person0_as id1_0_, person0_.country as country2_0_, person0_as name3_0_ from PERSON person0_ INFO : com.journaldev.

I am using Apache Commons DBCP for connection pooling, but in real life situations, most probably you have connection pooling done by the container and all we need is to provide the JNDI reference details to use. Person; @Repository public class Person DAOImpl implements Person DAO Notice that I am not using Hibernate Transaction, that is because it will be taken care by Spring framework. Service; import org.springframework.transaction.annotation. package com.journaldev.spring; import org.springframework.beans.factory.annotation. Autowired; import org.springframework.beans.factory.annotation. Person DAOImpl - Person List::id=15, name=Pankaj, country=USA This tutorial was aimed to provide sufficient details for you to getting started with Spring MVC and Hibernate integration, I hope you will find it useful.
NOTE: I noticed that some of the readers are getting database connection issues. Logger Factory; import org.springframework.stereotype. Here are our service classes that are using Hibernate DAO classes to work with Person objects. You can download final project from below link and play around with it.
The class name is being referred to the database table sometimes and class variable name can be referred to the database attribute names respectively.
But these names can be altered as user defined using annotations and their properties.
