Spring MVC3 Hibernate CRUD Sample Application

To learn any web framework starting with a HelloWorld application is a good idea. Once we get familiarity with the framework configuration it would be better to do a CRUD (Create,Read,Update,Delete) application which covers various aspects of a web framework like Validations, Request URL Mappings, Request Parameter Binding, Pre-populating forms etc.

Now I am going to explain how to write a Simple CRUD application using Spring MVC3, Hibernate and MySQL. Our Application is ContactsManagements where you can view or search contacts, create new contacts, edit or delete existing contacts.

Step#1: Create the CONTACTS Table

CREATE TABLE  CONTACTS
(
  id int(10) unsigned NOT NULL AUTO_INCREMENT,
  name varchar(45) NOT NULL,
  address varchar(45) DEFAULT NULL,
  gender char(1) DEFAULT 'M',
  dob datetime DEFAULT NULL,
  email varchar(45) DEFAULT NULL,
  mobile varchar(15) DEFAULT NULL,
  phone varchar(15) DEFAULT NULL,
  PRIMARY KEY (id)
);

Step#2: Copy the SpringMVC, Hibernate and their dependent jars into WEB-INF/lib folder. If you are using Maven you can mention the following dependencies.

<dependencies>
  <dependency>
    <groupid>junit</groupid>
    <artifactid>junit</artifactid>
    <version>4.8.1</version>
    <type>jar</type>

Step#3: Configure SpringMVC

a) Configure DispatcherServlet in web.xml

<servlet>
  <servlet-name>dispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
 </servlet>
  
 <servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>*.do</url-pattern>
 </servlet-mapping>
 
 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
 <context-param>
     <param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value>
  </context-param>

b) Configure View Resolver in WEB-INF/dispatcher-servlet.xml

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
 p:prefix="/jsp/" p:suffix=".jsp">
</bean>

c) Configure Annotation support, PropertyPlaceHolderConfigurer, ResourceBundleMessageSource in WEB-INF/classes/applicationContext.xml

<context:annotation-config></context:annotation-config>

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

<mvc:annotation-driven> </mvc:annotation-driven>

<context:property-placeholder location="classpath:config.properties"></context:property-placeholder>

<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" 
 p:basename="Messages"></bean>

Step#4: Configure JDBC connection parameters and Hibernate properties in config.properties

################### JDBC Configuration ##########################
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/sivalabs
jdbc.username=root
jdbc.password=admin
 
################### Hibernate Configuration ##########################
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
#hibernate.hbm2ddl.auto=update
hibernate.generate_statistics=true

Step#5: Configure DataSource, SessionFactory, TransactionManagement support in WEB-INF/classes/applicationContext.xml

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" 
 p:driverclassname="${jdbc.driverClassName}" p:url="${jdbc.url}" p:username="${jdbc.username}" p:password="${jdbc.password}">
</bean> 

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
 <property name="dataSource" ref="dataSource"></property>
 <property name="hibernateProperties">
  <props>       
  <prop key="hibernate.dialect">${hibernate.dialect}</prop>         
  <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
  </props>
 </property>
 <property name="packagesToScan" value="com.sivalabs"></property>
</bean>


<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" 
  p:sessionfactory-ref="sessionFactory">
</bean>

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

Step#6: Configure the Labels, error messages in WEB-INF/classes/Messages.properties

App.Title=SivaLabs
typeMismatch.java.util.Date={0} is Invalid Date.
dob=DOB

Step#7: Create the Entity class Contact.java

package com.sivalabs.contacts;
 
import java.util.Date;
 
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
 
import org.apache.commons.lang.builder.ToStringBuilder;
 
@Entity
@Table(name="CONTACTS")
public class Contact
{
 @Id
 @GeneratedValue(strategy = GenerationType.AUTO)
 private int id;
 @Column private String name;
 @Column private String address;
 @Column private String gender;
 @Column private Date dob;
 @Column private String email;
 @Column private String mobile;
 @Column private String phone;
  
 @Override
 public String toString()
 {
  return ToStringBuilder.reflectionToString(this);
 }
 //setters & getters
}

Step#8: Create the ContactsDAO.java which performs CRUD operations on CONTACTS table.

package com.sivalabs.contacts;
 
import java.util.List;
 
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
 
@Repository
@Transactional
public class ContactsDAO
{
 @Autowired
 private SessionFactory sessionFactory;
  
 public Contact getById(int id)
 {
  return (Contact) sessionFactory.getCurrentSession().get(Contact.class, id);
 }
  
 @SuppressWarnings("unchecked")
 public List searchContacts(String name)
 {
  Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Contact.class);
  criteria.add(Restrictions.ilike("name", name+"%"));
  return criteria.list();
 }
  
 @SuppressWarnings("unchecked")
 public List getAllContacts()
 {
  Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Contact.class);
  return criteria.list();
 }
  
 public int save(Contact contact)
 {
  return (Integer) sessionFactory.getCurrentSession().save(contact);
 }
  
 public void update(Contact contact)
 {
  sessionFactory.getCurrentSession().merge(contact);
 }
  
 public void delete(int id)
 {
  Contact c = getById(id);
  sessionFactory.getCurrentSession().delete(c);
 }
}

Step#9: Create ContactFormValidator.java which performs the validations on saving/updating a contact.

package com.sivalabs.contacts;
 
import org.springframework.stereotype.Component;
import org.springframework.validation.Errors;
import org.springframework.validation.ValidationUtils;
import org.springframework.validation.Validator;
 
@Component("contactFormValidator")
public class ContactFormValidator implements Validator
{
 @SuppressWarnings("unchecked")
 @Override
 public boolean supports(Class clazz)
 {
  return Contact.class.isAssignableFrom(clazz);
 }
 
 @Override
 public void validate(Object model, Errors errors)
 {
  ValidationUtils.rejectIfEmptyOrWhitespace(errors, "name","required.name", "Name is required.");
 }
}

Step#10: Create ContactsControllers.java which processes all the CRUD requests.

package com.sivalabs.contacts;
 
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.support.SessionStatus;
import org.springframework.web.servlet.ModelAndView;
 
@Controller
public class ContactsControllers
{
 @Autowired
 private ContactsDAO contactsDAO;
  
 @Autowired
 private ContactFormValidator validator;
   
 @InitBinder
 public void initBinder(WebDataBinder binder)
 {
  SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
  dateFormat.setLenient(false);
  binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
 }
   
 @RequestMapping("/searchContacts")
 public ModelAndView searchContacts(@RequestParam(required= false, defaultValue="") String name)
 {
  ModelAndView mav = new ModelAndView("showContacts");
  List contacts = contactsDAO.searchContacts(name.trim());
  mav.addObject("SEARCH_CONTACTS_RESULTS_KEY", contacts);
  return mav;
 }
  
 @RequestMapping("/viewAllContacts")
 public ModelAndView getAllContacts()
 {
  ModelAndView mav = new ModelAndView("showContacts");
  List contacts = contactsDAO.getAllContacts();
  mav.addObject("SEARCH_CONTACTS_RESULTS_KEY", contacts);
  return mav;
 }
  
 @RequestMapping(value="/saveContact", method=RequestMethod.GET)
 public ModelAndView newuserForm()
 {
  ModelAndView mav = new ModelAndView("newContact");
  Contact contact = new Contact();
  mav.getModelMap().put("newContact", contact);
  return mav;
 }
  
 @RequestMapping(value="/saveContact", method=RequestMethod.POST)
 public String create(@ModelAttribute("newContact")Contact contact, BindingResult result, SessionStatus status)
 {
  validator.validate(contact, result);
  if (result.hasErrors())
  {   
   return "newContact";
  }
  contactsDAO.save(contact);
  status.setComplete();
  return "redirect:viewAllContacts.do";
 }
  
 @RequestMapping(value="/updateContact", method=RequestMethod.GET)
 public ModelAndView edit(@RequestParam("id")Integer id)
 {
  ModelAndView mav = new ModelAndView("editContact");
  Contact contact = contactsDAO.getById(id);
  mav.addObject("editContact", contact);
  return mav;
 }
  
 @RequestMapping(value="/updateContact", method=RequestMethod.POST)
 public String update(@ModelAttribute("editContact") Contact contact, BindingResult result, SessionStatus status)
 {
  validator.validate(contact, result);
  if (result.hasErrors()) {
   return "editContact";
  }
  contactsDAO.update(contact);
  status.setComplete();
  return "redirect:viewAllContacts.do";
 }
   
 @RequestMapping("deleteContact")
 public ModelAndView delete(@RequestParam("id")Integer id)
 {
  ModelAndView mav = new ModelAndView("redirect:viewAllContacts.do");
  contactsDAO.delete(id);
  return mav;
 }
}

Step#11: Instead of writing the JSTL tag library declerations in all the JSPs, declare them in one JSP and include that JSP in other JSPs.

taglib_includes.jsp

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>
 
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>

Step#12: Create the JSPs.

a)showContacts.jsp

<%@include file="taglib_includes.jsp" %>
 
<html>

</td>      </tr>
</tbody></table></form:form></td>       </tr>
</tbody></table></body>
</html>

Step#13: Write the javascript file js/contacts.js containing the utility methods

function go(url)
{
 window.location = url;
}
 
function deleteContact(url)
{
 var isOK = confirm("Are you sure to delete?");
 if(isOK)
 {
  go(url);
 }
}

Step#14: The welcome file index.jsp

<%
response.sendRedirect("viewAllContacts.do");
%>

Step#15: Start the server and point your browser URL to http://localhost:8080/SpringMVCHibernate

Ohhhhh, is it a basic example?. With grails you can do the same in less than 5 minutes.
Take this "simple" tutorial will take some hours...

Java really needs to get better in some ways.

First, let me say that I greatly appreciate any Spring and Hibernate samples, as parent company Spring Source has done a lousy job of illustrating such integration. Unfortunately, this sample took an immense amount of time to configure. For one thing, the entire package org.apache.commons (for ToStringBuilder in the controller class) has been deprecated. As of July 2011, you can still download it from:

http://mavenhub.com/mvn/deprecated/apache-lang/commons-lang/2.1

Secondly, the ContactsDAO class has two methods with typos in the signatures searchContacts(String name) and getAllContacts():

List should be List

It would save everyone a great deal of effort, if the author could provide the entire project as a tar or zip file, and include an image of the final project tree.

Thanks.

thank you for this "Simple!!!" sample.
there are 2 moments I'm concern about:

1) why should i write more then 100 lines of code to handle a table? what if i have database with more then 100 of tables which needs controller too? is that the best way java could refer me?

2) how about performance? can this method handle a table with more then 100 millions of records?
