Integrate Hibernate with Spring

4 simple steps to Integrate Hibernate with Spring

Step 1: Add the entries in spring-context.xml

<bean id="DS" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >

        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

        <property name="url" value="jdbc:mysql://localhost/webusers"/>

        <property name="username" value="root"/>

        <property name="password" value="root"/>

</bean>

<context:component-scan base-package="com.hib.javabeam" />

<tx:annotation-driven transaction-manager="transactionManager" />

      

Step 2: Create a class which will serve you Session Factory

package com.hib.javabeam.utils.hibernate;

import java.util.Properties;

import javax.sql.DataSource;

import org.hibernate.dialect.MySQL5Dialect;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.orm.hibernate3.HibernateTransactionManager;

import org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean;

import com.hib.javabeam.domain.CustomerDetails;

import com.hib.javabeam.domain.Item;

import com.hib.javabeam.domain.Order;

@Configuration

public class HibernateConfiguration {

   @Value("#{DS}")

   private DataSource dataSource;

   @Bean

   public AnnotationSessionFactoryBean sessionFactoryBean() {

          Properties props = new Properties();

          props.put("hibernate.dialect",MySQL5Dialect.class.getName());

          props.put("hibernate.format_sql", "true");

          AnnotationSessionFactoryBean bean = new AnnotationSessionFactoryBean();

          bean.setAnnotatedClasses(new Class[]{Item.class, Order.class, CustomerDetails.class});     

          bean.setHibernateProperties(props);

          bean.setDataSource(dataSource);

          bean.setSchemaUpdate(true);

          return bean;

   }

   @Bean

   public HibernateTransactionManager transactionManager() {

          return new HibernateTransactionManager( sessionFactoryBean().getObject() );

   }

}

Step 3: Create a DAO interface

package com.hib.javabeam.dao.api;

import com.hib.javabeam.domain.CustomerDetails;

public interface CustomerDetailsDAO {

      

       public void addCustomerDetails(CustomerDetails custDetails);

}

Step 4 : Implements DAO interface and perform the your operations

package com.hib.javabeam.dao.impl;

import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

import org.springframework.transaction.annotation.Transactional;

import com.hib.javabeam.dao.api.CustomerDetailsDAO;

import com.hib.javabeam.domain.CustomerDetails;

@Repository("cusomerDetailsDAO")

public class CustomerDetailsDAOImpl implements CustomerDetailsDAO {

       @Autowired

       SessionFactory sessionfactory;

      

       @Transactional

       public void addCustomerDetails(CustomerDetails custDetails) {

              sessionfactory.getCurrentSession().save(custDetails);

       }

}
