1. Overview

In this article, we’ll discuss how to bootstrap Hibernate 5 with Spring, using both Java and XML configuration.

2. Spring Integration

Bootstrapping a SessionFactory with the native Hibernate API is a bit complicated and would take us quite a few lines of code (have a look at the official documentation in case you really need to do that).

Fortunately, Spring supports bootstrapping the SessionFactory – so that we only need a few lines of Java code or XML configuration.

Also, before we jump in, if you’re working with older versions of Hibernate, you can have a look at the articles about Hibernate 3 as well as Hibernate 4 with Spring.

3. Maven Dependencies

Let’s get started by first adding the necessary dependencies to our pom.xml :


The spring-orm module provides the Spring integration with Hibernate :


We’ll use MySQL as our database :


Finally, we are going to use Tomcat JDBC Connection Pooling, which fits better for production purposes than the DriverManagerDataSource provided by Spring :


4. Configuration

As mentioned before, Spring supports us with bootstrapping the Hibernate SessionFactory.

All we have to do is to define some beans as well as a few parameters.

With Spring, we have two options for these configurations, a Java-based and an XML-based way.

4.1. Using Java Configuration

For using Hibernate 5 with Spring, little has changed since Hibernate 4: we have to use LocalSessionFactoryBean from the package org.springframework.orm.hibernate5 instead of org.springframework.orm.hibernate4.

Like with Hibernate 4 before, we have to define beans for LocalSessionFactoryBeanDataSource, and PlatformTransactionManager, as well as some Hibernate-specific properties.

Let’s create our DBConfiguration class to configure Hibernate 5 with Spring:

package com.codeFactory.configuration;

import java.util.Properties;

import javax.sql.DataSource;

import org.apache.tomcat.dbcp.dbcp2.BasicDataSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.orm.hibernate5.HibernateTransactionManager;
import org.springframework.orm.hibernate5.LocalSessionFactoryBean;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;

public class DBConfiguration {

    public LocalSessionFactoryBean sessionFactory() {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        return sessionFactory;

	public DataSource dataSource() {
		BasicDataSource dataSource = new BasicDataSource();
		return dataSource;

	public PlatformTransactionManager hibernateTransactionManager() {
		HibernateTransactionManager transactionManager = new HibernateTransactionManager();
		return transactionManager;

	private final Properties hibernateProperties() {
		Properties hibernateProperties = new Properties();
		hibernateProperties.setProperty("", "update");
		hibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
		return hibernateProperties;

4.2. Using XML Configuration

As a secondary option, we can also configure Hibernate 5 with an XML-based configuration :

hibernate5Configuration.xml (create file in src/main/resources)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=""
	<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="packagesToScan" value="com.codeFactory"/>
        <property name="hibernateProperties">
                <prop key="">
                <prop key="hibernate.dialect">
    <bean id="dataSource"
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/test_connection"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
    <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>

As we can easily see, we’re defining exactly the same beans and parameters as in the Java-based configuration earlier.

To bootstrap the XML into the Spring context, we can use a simple Java configuration file if the application is configured with Java configuration :

package com.codeFactory.configuration;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.transaction.annotation.EnableTransactionManagement;

public class DBConfiguration {


Alternatively, we can simply provide the XML file to the Spring Context, if the overall configuration is purely XML.

5. Usage

At this point, Hibernate 5 is fully configured with Spring, and we can inject the raw HibernateSessionFactory directly whenever we need to :

package com.codeFactory.controller;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RestController;

public class Controller {

	SessionFactory sessionFactory;
