1) Create a dynamic web project using maven in eclipse named "SpringMVCHibernateCRUDExample"

Maven dependencies 

2) We are using Spring 4 and Hibernate 4 for this application. It should work with hibernate 3 also but we need to do small changes in hibernate configuration.

Spring application configuration:

3) Change web.xml as below:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">
	<display-name>Archetype Created Web Application</display-name>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>/WEB-INF/applicationcontext.xml</param-value>
	</context-param>
	<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

	<servlet>
 <servlet-name>spring</servlet-name>
 <servlet-class>
  org.springframework.web.servlet.DispatcherServlet

 <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
 <servlet-name>spring</servlet-name>
 <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>
4) create a xml file named spring-servlet.xml in /WEB-INF/ folder.
Please change context:component-scan if you want to use different package for spring to search for controller.Please refer to spring mvc hello world example for more understanding.
<?xml version="1.0" encoding="UTF-8"?>

</beans:beans>

In Spring-servlet.xml, we have done hibernate configuration.
dataSource bean is used to specify java data source. We need to provide driver, URL , Username and Password.
transactionManager bean is used to configure hibernate transaction manager. hibernate4AnnotatedSessionFactory bean is used to configure FactoryBean that creates a Hibernate SessionFactory. This is the common way to set up a shared Hibernate SessionFactory in a Spring application context, so you can use this SessionFactory to inject in Hibernate data access objects.
Create a applicationcontext.xml in WEB-INF folder, this file is used for bean configuration as we are using spring-servlet.xml for bean configuration , we will keep this file empty.
<?xml version="1.0" encoding="UTF-8"?>

Create bean class 

4) Create a bean name "Country.java" in org.arpit.java2blog.bean.
package org.arpit.java2blog.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

/*
 * This is our model class and it corresponds to Country table in database
 */
@Entity
@Table(name="COUNTRY")
public class Country{
 
 @Id
 @Column(name="id")
 @GeneratedValue(strategy=GenerationType.IDENTITY)
 int id;
 
 @Column(name="countryName")
 String countryName; 
 
 @Column(name="population")
 long population;
 
 public Country() {
  super();
 }
 public Country(int i, String countryName,long population) {
  super();
  this.id = i;
  this.countryName = countryName;
  this.population=population;
 }
 public int getId() {
  return id;
 }
 public void setId(int id) {
  this.id = id;
 }
 public String getCountryName() {
  return countryName;
 }
 public void setCountryName(String countryName) {
  this.countryName = countryName;
 }
 public long getPopulation() {
  return population;
 }
 public void setPopulation(long population) {
  this.population = population;
 } 
 
}
@Entity is used for making a persistent pojo class.For this java class,you will have corresponding table in database. @Column is used to map annotated attribute to corresponding column in table. So Create Country table in mysql database with following code:
CREATE TABLE COUNTRY
(
   id int PRIMARY KEY NOT NULL AUTO_INCREMENT,
   countryName varchar(100) NOT NULL,
   population int NOT NULL
)
;

Create Controller 

5) Create a controller named "CountryController.java" in package org.arpit.java2blog.controller
package org.arpit.java2blog.controller;


import java.util.List;

import org.arpit.java2blog.model.Country;
import org.arpit.java2blog.service.CountryService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class CountryController {
	
	@Autowired
	CountryService countryService;
	
	@RequestMapping(value = "/getAllCountries", method = RequestMethod.GET, headers = "Accept=application/json")
	public String getCountries(Model model) {
		
		List<Country> listOfCountries = countryService.getAllCountries();
		model.addAttribute("country", new Country());
		model.addAttribute("listOfCountries", listOfCountries);
		return "countryDetails";
	}

	@RequestMapping(value = "/getCountry/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
	public Country getCountryById(@PathVariable int id) {
		return countryService.getCountry(id);
	}

	@RequestMapping(value = "/addCountry", method = RequestMethod.POST, headers = "Accept=application/json")
	public String addCountry(@ModelAttribute("country") Country country) {	
		if(country.getId()==0)
		{
			countryService.addCountry(country);
		}
		else
		{	
			countryService.updateCountry(country);
		}
		
		return "redirect:/getAllCountries";
	}

	@RequestMapping(value = "/updateCountry/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
	public String updateCountry(@PathVariable("id") int id,Model model) {
		 model.addAttribute("country", this.countryService.getCountry(id));
	        model.addAttribute("listOfCountries", this.countryService.getAllCountries());
	        return "countryDetails";
	}

	@RequestMapping(value = "/deleteCountry/{id}", method = RequestMethod.GET, headers = "Accept=application/json")
	public String deleteCountry(@PathVariable("id") int id) {
		countryService.deleteCountry(id);
		 return "redirect:/getAllCountries";

	}	
}

Create DAO class

Create a class CountryDAO.java in package org.arpit.java2blog.dao.  This class will execute hibernate statements while interacting with database.
package org.arpit.java2blog.dao;

import java.util.List;

import org.arpit.java2blog.model.Country;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository
public class CountryDAO {

 @Autowired
 private SessionFactory sessionFactory;

 public void setSessionFactory(SessionFactory sf) {
  this.sessionFactory = sf;
 }

 public List<Country> getAllCountries() {
  Session session = this.sessionFactory.getCurrentSession();
  List<Country> countryList = session.createQuery("from Country").list();
  return countryList;
 }

 public Country getCountry(int id) {
  Session session = this.sessionFactory.getCurrentSession();
  Country country = (Country) session.load(Country.class, new Integer(id));
  return country;
 }

 public Country addCountry(Country country) {
  Session session = this.sessionFactory.getCurrentSession();
  session.persist(country);
  return country;
 }

 public void updateCountry(Country country) {
  Session session = this.sessionFactory.getCurrentSession();
  session.update(country);
 }

 public void deleteCountry(int id) {
  Session session = this.sessionFactory.getCurrentSession();
  Country p = (Country) session.load(Country.class, new Integer(id));
  if (null != p) {
   session.delete(p);
  }
 } 
}

@Repository is specialised component annotation which is used to create bean at DAO layer. We have use Autowired annotation to inject hibernate SessionFactory into CountryDAO class. We have already configured hibernate SessionFactory object in Spring-Servlet.xml file.

Create Service class

6) Create a class CountryService.java in package org.arpit.java2blog.service
It is service level class. It will call DAO layer class.
package org.arpit.java2blog.service;

import java.util.List;
import org.arpit.java2blog.dao.CountryDAO;
import org.arpit.java2blog.model.Country;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service("countryService")
public class CountryService {

 @Autowired
 CountryDAO countryDao;
 
 @Transactional
 public List<Country> getAllCountries() {
  return countryDao.getAllCountries();
 }

 @Transactional
 public Country getCountry(int id) {
  return countryDao.getCountry(id);
 }

 @Transactional
 public void addCountry(Country country) {
  countryDao.addCountry(country);
 }

 @Transactional
 public void updateCountry(Country country) {
  countryDao.updateCountry(country);

 }

 @Transactional
 public void deleteCountry(int id) {
  countryDao.deleteCountry(id);
 }
}

@Service is specialised component annotation which is used to create bean at Service layer.

Create view

Create view called countryDetails.jsp in WEB-INF/view/ folder.
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://www.springframework.org/tags" prefix="spring" %>

	</c:forEach>
	</table>
</c:if>
</body>
</html>

8) It 's time to do maven build.
Right click on project -> Run as -> Maven build
Maven build in eclipse

9) Provide goals as clean install (given below) and click on run
Maven build in eclipse

Run the application

10) Right click on project -> run as -> run on server
Select apache tomcat and click on finish

11)  Now lets hit below URL to getAllCountries.
http://localhost:8080/SpringMVCHibernateCRUDExample/getAllCountries
You will get below screen:
Empty Country List Spring MVC hibernate
As you can see, we did not add any country to the list, so it is empty.
Lets add Country named India to country list and click submit.
Similarly we will add China , Bhutan and Nepal respectively and you will see below screen.
All Country List Spring MVC hibernate


Lets edit population of Bhutan to 15000. Click on edit button corresponds to Bhutan.

When you click on submit, you will get below screen.
Lets delete country China from above list, click on delete button corresponds to 2nd row.
You will see below screen.
As you can see, china got deleted from above list.

Spring MVC Hibernate CRUD example

We are done with Spring MVC hibernate MySQL CRUD example. If you are still facing any issue, please comment.

If you getting 404 error with above steps, you may need to follow below steps:


1) If you are getting this warning into your Tomcat startup console log, then it can cause the issue

WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server: JAXRSJsonCRUDExample' did not find a matching property.

This particular warning basically means that the <Context> element in Tomcat's server.xml contains an unknown attribute source and that Tomcat doesn't know what to do with this attribute and therefore will ignore it.
To resolve this in eclipse,
Remove the project from the server from the Server View. Right click on server -> add and remove

then remove project from server configuration.
Then run the project under the same server. Warning should be removed now
Or if warning still remains then
  • Go to server view
  • Double click on your tomcat server. It will open the server configuration.
  • Under server options check ‘Publish module contents to separate XML files’ checkbox. 
  • Restart your server. This time your page will come without any issues.
2) Try to update Maven project.
Right click on project ->Maven-> update project
Update Maven project
then

This should solve you issues.
