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

01	CREATE TABLE  CONTACTS

02

(

03	id int(10) unsigned NOT NULL AUTO_INCREMENT,

04	name varchar(45) NOT NULL,

05	address varchar(45) DEFAULT NULL,

06	gender char(1) DEFAULT 'M',

07	dob datetime DEFAULT NULL,

08	email varchar(45) DEFAULT NULL,

09	mobile varchar(15) DEFAULT NULL,

10	phone varchar(15) DEFAULT NULL,

11	PRIMARY KEY (id)

12

);

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.

Step#3: Configure SpringMVC
a) Configure DispatcherServlet in web.xml

01

<servlet>

02	<servlet-name>dispatcher</servlet-name>

03	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

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

05	</servlet>

06

07	<servlet-mapping>

08	<servlet-name>dispatcher</servlet-name>

09	<url-pattern>*.do</url-pattern>

10	</servlet-mapping>

11

12	<listener>

13	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

14	</listener>

15	<context-param>

16	<param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value>

17	</context-param>

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

1	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"

2	p:prefix="/jsp/" p:suffix=".jsp">

3

</bean>

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

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

02

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

04

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

06

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

08

09	<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource"

10	p:basename="Messages"></bean>

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

01	################### JDBC Configuration ##########################

02	jdbc.driverClassName=com.mysql.jdbc.Driver

03	jdbc.url=jdbc:mysql://localhost:3306/sivalabs

04	jdbc.username=root

05	jdbc.password=admin

06

07	################### Hibernate Configuration ##########################

08	hibernate.dialect=org.hibernate.dialect.MySQLDialect

09	hibernate.show_sql=true

10	#hibernate.hbm2ddl.auto=update

11	hibernate.generate_statistics=true

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

01	<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"

02	p:driverclassname="${jdbc.driverClassName}" p:url="${jdbc.url}" p:username="${jdbc.username}" p:password="${jdbc.password}">

03

</bean>

04

05	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

06	<property name="dataSource" ref="dataSource"></property>

07	<property name="hibernateProperties">

08

<props>

09	<prop key="hibernate.dialect">${hibernate.dialect}</prop>

10	<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>

11

</props>

12	</property>

13	<property name="packagesToScan" value="com.sivalabs"></property>

14

</bean>

15

16

17	<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"

18	p:sessionfactory-ref="sessionFactory">

19

</bean>

20

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

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

1	App.Title=SivaLabs

2	typeMismatch.java.util.Date={0} is Invalid Date.

3

dob=DOB

Step#7: Create the Entity class Contact.java

01	package com.sivalabs.contacts;

02

03	import java.util.Date;

04

05	import javax.persistence.Column;

06	import javax.persistence.Entity;

07	import javax.persistence.GeneratedValue;

08	import javax.persistence.GenerationType;

09	import javax.persistence.Id;

10	import javax.persistence.Table;

11

12	import org.apache.commons.lang.builder.ToStringBuilder;

13

14

@Entity

15	@Table(name="CONTACTS")

16	public class Contact

17

{

18

@Id

19	@GeneratedValue(strategy = GenerationType.AUTO)

20	private int id;

21	@Column private String name;

22	@Column private String address;

23	@Column private String gender;

24	@Column private Date dob;

25	@Column private String email;

26	@Column private String mobile;

27	@Column private String phone;

28

29

@Override

30	public String toString()

31

{

32	return ToStringBuilder.reflectionToString(this);

33

}

34	//setters & getters

35

}

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

01	package com.sivalabs.contacts;

02

03	import java.util.List;

04

05	import org.hibernate.Criteria;

06	import org.hibernate.SessionFactory;

07	import org.hibernate.criterion.Restrictions;

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

09	import org.springframework.stereotype.Repository;

10	import org.springframework.transaction.annotation.Transactional;

11

12	@Repository

13	@Transactional

14	public class ContactsDAO

15

{

16	@Autowired

17	private SessionFactory sessionFactory;

18

19	public Contact getById(int id)

20

{

21	return (Contact) sessionFactory.getCurrentSession().get(Contact.class, id);

22

}

23

24	@SuppressWarnings("unchecked")

25	public List searchContacts(String name)

26

{

27	Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Contact.class);

28	criteria.add(Restrictions.ilike("name", name+"%"));

29	return criteria.list();

30

}

31

32	@SuppressWarnings("unchecked")

33	public List getAllContacts()

34

{

35	Criteria criteria = sessionFactory.getCurrentSession().createCriteria(Contact.class);

36	return criteria.list();

37

}

38

39	public int save(Contact contact)

40

{

41	return (Integer) sessionFactory.getCurrentSession().save(contact);

42

}

43

44	public void update(Contact contact)

45

{

46	sessionFactory.getCurrentSession().merge(contact);

47

}

48

49	public void delete(int id)

50

{

51	Contact c = getById(id);

52	sessionFactory.getCurrentSession().delete(c);

53

}

54

}

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

01	package com.sivalabs.contacts;

02

03	import org.springframework.stereotype.Component;

04	import org.springframework.validation.Errors;

05	import org.springframework.validation.ValidationUtils;

06	import org.springframework.validation.Validator;

07

08	@Component("contactFormValidator")

09	public class ContactFormValidator implements Validator

10

{

11	@SuppressWarnings("unchecked")

12

@Override

13	public boolean supports(Class clazz)

14

{

15	return Contact.class.isAssignableFrom(clazz);

16

}

17

18

@Override

19	public void validate(Object model, Errors errors)

20

{

21	ValidationUtils.rejectIfEmptyOrWhitespace(errors, "name","required.name", "Name is required.");

22

}

23

}

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

001	package com.sivalabs.contacts;

002

003	import java.text.SimpleDateFormat;

004	import java.util.Date;

005	import java.util.List;

006

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

008	import org.springframework.beans.propertyeditors.CustomDateEditor;

009	import org.springframework.stereotype.Controller;

010	import org.springframework.validation.BindingResult;

011	import org.springframework.web.bind.WebDataBinder;

012	import org.springframework.web.bind.annotation.InitBinder;

013	import org.springframework.web.bind.annotation.ModelAttribute;

014	import org.springframework.web.bind.annotation.RequestMapping;

015	import org.springframework.web.bind.annotation.RequestMethod;

016	import org.springframework.web.bind.annotation.RequestParam;

017	import org.springframework.web.bind.support.SessionStatus;

018	import org.springframework.web.servlet.ModelAndView;

019

020	@Controller

021	public class ContactsControllers

022

{

023	@Autowired

024	private ContactsDAO contactsDAO;

025

026	@Autowired

027	private ContactFormValidator validator;

028

029	@InitBinder

030	public void initBinder(WebDataBinder binder)

031

{

032	SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");

033	dateFormat.setLenient(false);

034	binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));

035

}

036

037	@RequestMapping("/searchContacts")

038	public ModelAndView searchContacts(@RequestParam(required= false, defaultValue="") String name)

039

{

040	ModelAndView mav = new ModelAndView("showContacts");

041	List contacts = contactsDAO.searchContacts(name.trim());

042	mav.addObject("SEARCH_CONTACTS_RESULTS_KEY", contacts);

043	return mav;

044

}

045

046	@RequestMapping("/viewAllContacts")

047	public ModelAndView getAllContacts()

048

{

049	ModelAndView mav = new ModelAndView("showContacts");

050	List contacts = contactsDAO.getAllContacts();

051	mav.addObject("SEARCH_CONTACTS_RESULTS_KEY", contacts);

052	return mav;

053

}

054

055	@RequestMapping(value="/saveContact", method=RequestMethod.GET)

056	public ModelAndView newuserForm()

057

{

058	ModelAndView mav = new ModelAndView("newContact");

059	Contact contact = new Contact();

060	mav.getModelMap().put("newContact", contact);

061	return mav;

062

}

063

064	@RequestMapping(value="/saveContact", method=RequestMethod.POST)

065	public String create(@ModelAttribute("newContact")Contact contact, BindingResult result, SessionStatus status)

066

{

067	validator.validate(contact, result);

068	if (result.hasErrors())

069

{

070	return "newContact";

071

}

072	contactsDAO.save(contact);

073	status.setComplete();

074	return "redirect:viewAllContacts.do";

075

}

076

077	@RequestMapping(value="/updateContact", method=RequestMethod.GET)

078	public ModelAndView edit(@RequestParam("id")Integer id)

079

{

080	ModelAndView mav = new ModelAndView("editContact");

081	Contact contact = contactsDAO.getById(id);

082	mav.addObject("editContact", contact);

083	return mav;

084

}

085

086	@RequestMapping(value="/updateContact", method=RequestMethod.POST)

087	public String update(@ModelAttribute("editContact") Contact contact, BindingResult result, SessionStatus status)

088

{

089	validator.validate(contact, result);

090	if (result.hasErrors()) {

091	return "editContact";

092

}

093	contactsDAO.update(contact);

094	status.setComplete();

095	return "redirect:viewAllContacts.do";

096

}

097

098	@RequestMapping("deleteContact")

099	public ModelAndView delete(@RequestParam("id")Integer id)

100

{

101	ModelAndView mav = new ModelAndView("redirect:viewAllContacts.do");

102	contactsDAO.delete(id);

103	return mav;

104

}

105

}

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

1	<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

2	<%@taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>

3

4	<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

5	<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>

Step#12: Create the JSPs.
