Tutorial: Create Struts2 Hibernate Example in Eclipse

By Viral Patel on January 15, 2010

This is a demo Contact Manager application that we will create using Struts2 and Hibernate framework. In this article we will see how we can use Hibernate to perform Insert / Delete operations in Struts2 framework.

Our Goal

Our goal will be to demonstrate the use of Struts2 with Hibernate framework and to create a demo application “Contact Manager”. The basic requirement of the Contact Manager app will be:

Add new contact in the contact list.
Display all contacts from contact list.
Delete a contact from contact list.

Once we will build the application it will look like:
struts2-hibernate-contact-manager

Getting Started

For our Contact Manager example, we will use MySQL database. Create a table contacts in any MySQL database. This is very preliminary example and thus we have minimum columns to represent a contact. Feel free to extend this example and create a more complex application.

CREATE TABLE CONTACTS
( 	
	id 		INT PRIMARY KEY AUTO_INCREMENT,
	firstname 	VARCHAR(30),
	lastname	VARCHAR(30),
	cell_no		VARCHAR(15),
	email_id	VARCHAR(30),
	website		VARCHAR(150),
	birthdate	DATE,
	created		TIMESTAMP DEFAULT NOW()
);

Creating Project in Eclipse

Open Eclipse and goto File -> New -> Project and select Dynamic Web Project in the New Project wizard screen.
struts dynamic web project

After selecting Dynamic Web Project, press Next.

Write the name of the project. For example ContactManager. Once this is done, select the target runtime environment (e.g. Apache Tomcat v6.0). This is to run the project inside Eclipse environment. After this press Finish.

We will need a source folder called resources. Right click on Project in project explorer and select New -> Source Folder and create a folder with name resources.

Also we will create Java packages for our application. As we will use Struts2, we will follow MVC architecture. Create 4 packages in the sources.
struts2-hibernate-package

We created 4 new packages. The net.viralpatel.contact.controller will hold the Java class that will act as controller and will fetch the data from database and pass it to view. The net.viralpatel.contact.model package will hold the Hibernate persistent model class. The net.viralpatel.contact.view will contain the struts2 action class. And finally the net.viralpatel.contact.util will have some hibernate related util file that will be see shortly.

Required JAR Files

Now copy all the required JAR files in WebContent -> WEB-INF -> lib folder. Create this folder if it does not exists.

Create JSP for Contact Manager

We will need only one JSP file for this tutorial. The JSP will include a form to add new contact as well as will list the contacts at the end. Create a JSP file index.jsp in WebContent folder and copy following content into it.
WebContent/index.jsp

<%@ page contentType="text/html; charset=UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
	<title>Contact Manager - Struts2 Hibernate Example</title>
</head>
<body>

<h1>Contact Manager</h1>
<s:actionerror/>

<s:form action="add" method="post">
	<s:textfield name="contact.firstName" label="Firstname"/>
	<s:textfield name="contact.lastName" label="Lastname"/>
	<s:textfield name="contact.emailId" label="Email"/>
	<s:textfield name="contact.cellNo" label="Cell No."/>
	<s:textfield name="contact.website" label="Homepage"/>
	<s:textfield name="contact.birthDate" label="Birthdate"/>
	<s:submit value="Add Contact" align="center"/>
</s:form>


<h2>Contacts</h2>
<table>
<tr>
	<th>Name</th>
	<th>Email</th>
	<th>Cell No.</th>
	<th>Birthdate</th>
	<th>Homepage</th>
	<th>Delete</th>
</tr>
<s:iterator value="contactList" var="contact">
	<tr>
		<td><s:property value="lastName"/>, <s:property value="firstName"/> </td>
		<td><s:property value="emailId"/></td>
		<td><s:property value="cellNo"/></td>
		<td><s:property value="birthDate"/></td>
		<td><a href="<s:property value="website"/>">link</a></td>
		<td><a href="delete?id=<s:property value="id"/>">delete</a></td>
	</tr>	
</s:iterator>
</table>
</body>
</html>

Adding Hibernate Support

For adding hibernate support, we will add following source code in Contact Manager application.
hibernate.cfg.xml – This is the Hibernate configuration file. This file will contain configurations such as database connection information, persistence class info etc. Create hibernate.cfg.xml under resources folder and copy following content into it.

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
	<session-factory>
		<property name="connection.driver_class">
			com.mysql.jdbc.Driver
		</property>
		<property name="connection.url">
			jdbc:mysql://localhost:3306/ContactManager
		</property>
		<property name="connection.username">root</property>
		<property name="connection.password">root</property>
		<property name="connection.pool_size">1</property>
		<property name="dialect">
			org.hibernate.dialect.MySQLDialect
		</property>
		<property name="current_session_context_class">thread</property>
		<property name="cache.provider_class">
			org.hibernate.cache.NoCacheProvider
		</property>
		<property name="show_sql">true</property>
		<property name="hbm2ddl.auto">update</property>

		<mapping class="net.viralpatel.contact.model.Contact" />

	</session-factory>
</hibernate-configuration>

HibernateUtil.java – This is the Util file that we use to create connection with hibernate. Create HibernateUtil.java under package net.viralpatel.contact.util and copy following content into it.

package net.viralpatel.contact.util;

import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;

public class HibernateUtil {

	private static final SessionFactory sessionFactory = buildSessionFactory();

	private static SessionFactory buildSessionFactory() {
		try {
			// Create the SessionFactory from hibernate.cfg.xml
			return new AnnotationConfiguration().configure()
					.buildSessionFactory();
		} catch (Throwable ex) {
			System.err.println("Initial SessionFactory creation failed." + ex);
			throw new ExceptionInInitializerError(ex);
		}
	}

	public static SessionFactory getSessionFactory() {
		return sessionFactory;
	}
}

Contact.java – This is the persistence entity class that will map to Contacts table in MySQL. Create Contact.java under net.viralpatel.contact.model package and copy following content into it.

package net.viralpatel.contact.model;

import java.io.Serializable;
import java.sql.Date;

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

@Entity
@Table(name="Contacts")
public class Contact implements Serializable{
	
	private static final long serialVersionUID = -8767337896773261247L;

	private Long id;
	private String firstName;
	private String lastName;
	private String emailId;
	private String cellNo;
	private Date birthDate;
	private String website;
	
	private Date created;

	@Id
	@GeneratedValue
	@Column(name="id")
	public Long getId() {
		return id;
	}
	@Column(name="firstname")
	public String getFirstName() {
		return firstName;
	}
	@Column(name="lastname")
	public String getLastName() {
		return lastName;
	}
	@Column(name="email_id")
	public String getEmailId() {
		return emailId;
	}
	@Column(name="cell_no")
	public String getCellNo() {
		return cellNo;
	}
	@Column(name="birthdate")
	public Date getBirthDate() {
		return birthDate;
	}
	@Column(name="website")
	public String getWebsite() {
		return website;
	}
	@Column(name="created")
	public Date getCreated() {
		return created;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}
	public void setLastName(String lastName) {
		this.lastName = lastName;
	}
	public void setEmailId(String emailId) {
		this.emailId = emailId;
	}
	public void setCellNo(String cellNo) {
		this.cellNo = cellNo;
	}
	public void setBirthDate(Date birthDate) {
		this.birthDate = birthDate;
	}
	public void setCreated(Date created) {
		this.created = created;
	}
	public void setWebsite(String website) {
		this.website = website;
	}
}

Note how we have mapped Contact class with Contacts table using Java persistence API annotations.

Adding Controller to access data

We will add a controller class in Contact Manager application which will be used to get/save data from hibernate. This controller will be invoked from Struts action class. Create a file ContactManager.java under net.viralpatel.contact.controller package and copy following content into it.

package net.viralpatel.contact.controller;


import java.util.List;


import org.hibernate.HibernateException;
import org.hibernate.classic.Session;

import net.viralpatel.contact.model.Contact;
import net.viralpatel.contact.util.HibernateUtil;

public class ContactManager extends HibernateUtil {

	public Contact add(Contact contact) {
		Session session = HibernateUtil.getSessionFactory().getCurrentSession();
		session.beginTransaction();
		session.save(contact);
		session.getTransaction().commit();
		return contact;
	}
	public Contact delete(Long id) {
		Session session = HibernateUtil.getSessionFactory().getCurrentSession();
		session.beginTransaction();
		Contact contact = (Contact) session.load(Contact.class, id);
		if(null != contact) {
			session.delete(contact);
		}
		session.getTransaction().commit();
		return contact;
	}

	public List<Contact> list() {
		
		Session session = HibernateUtil.getSessionFactory().getCurrentSession();
		session.beginTransaction();
		List<Contact> contacts = null;
		try {
			
			contacts = (List<Contact>)session.createQuery("from Contact").list();
			
		} catch (HibernateException e) {
			e.printStackTrace();
			session.getTransaction().rollback();
		}
		session.getTransaction().commit();
		return contacts;
	}
}

Note that how we have created different methods in controller class to add/delete/list the contacts. Also the ContactManager class is extending HibernateUtil class thus allowing it to access sessionFactory object.

Adding Struts2 Support

Let us add Struts2 support to our web application. For that, will add following entry in deployment descriptor (WEB-INF/web.xml).

Add Struts2 Filter in web.xml

<filter>
	<filter-name>struts2</filter-name>
	<filter-class>
		org.apache.struts2.dispatcher.FilterDispatcher
	</filter-class>
</filter>
<filter-mapping>
	<filter-name>struts2</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

Creating struts.xml

We will need to create struts.xml file that will hold the action mapping for our example. Create a file struts.xml in resources folder and add following content into it.
struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<constant name="struts.enable.DynamicMethodInvocation"
		value="false" />
	<constant name="struts.devMode" value="false" />

	<package name="default" extends="struts-default" namespace="/">

		<action name="add"
			class="net.viralpatel.contact.view.ContactAction" method="add">
			<result name="success" type="chain">index</result>
			<result name="input" type="chain">index</result>
		</action>

		<action name="delete"
			class="net.viralpatel.contact.view.ContactAction" method="delete">
			<result name="success" type="chain">index</result>
		</action>

		<action name="index"
			class="net.viralpatel.contact.view.ContactAction">
			<result name="success">index.jsp</result>
		</action>
	</package>
</struts>

Create Action class

Up-till now we have almost completed our Contact Manager application in Struts2 and Hibernate. Only task left is to add Struts Action class. Create a class ContactAction.java under net.viralpatel.contact.view package and copy following content into it.

package net.viralpatel.contact.view;

import java.util.List;

import net.viralpatel.contact.controller.ContactManager;
import net.viralpatel.contact.model.Contact;

import com.opensymphony.xwork2.ActionSupport;


public class ContactAction extends ActionSupport {

	private static final long serialVersionUID = 9149826260758390091L;
	private Contact contact;
	private List<Contact> contactList;
	private Long id;

	private ContactManager contactManager;

	public ContactAction() {
		contactManager = new ContactManager();
	}

	public String execute() {
		this.contactList = contactManager.list();
		System.out.println("execute called");
		return SUCCESS;
	}

	public String add() {
		System.out.println(getContact());
		try {
			contactManager.add(getContact());
		} catch (Exception e) {
			e.printStackTrace();
		}
		this.contactList = contactManager.list();
		return SUCCESS;
	}

	public String delete() {
		contactManager.delete(getId());
		return SUCCESS;
	}

	public Contact getContact() {
		return contact;
	}

	public List<Contact> getContactList() {
		return contactList;
	}

	public void setContact(Contact contact) {
		this.contact = contact;
	}

	public void setContactList(List<Contact> contactsList) {
		this.contactList = contactsList;
	}

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}
}

ContactAction class contains different methods that gets called by Struts2. The execute() method is the default method which gets called when we call /index action from browser. It fetches the list of contacts and display it in index.jsp. Similarly, when a new contact is added, add() method is called. If you check the action mapping entry in struts.xml for add() method, the <result> is mapped with /index action and the type is chain. This is because we want to display the list of contact once we add a new one. Hence we have done Action chaining and called /index action after /add action.

The Contact Manager App

That’s it. The app is ready, just compile and run the project in Eclipse Run -> Run As -> Run on Server. Set the URL to:
http://localhost:<port>/<project name>/index

struts2-hibernate-contact-manager
Fill the contact form and hit enter and the new contact will be persisted in database and will be shown in below table. Similarly, click on delete link next to a record. It will delete the record from database.

Let me know your input about this application.
Cheers.

Hello VP, and thank u for this tutorial,
if i want to add to this code an update, like update next to the delete link with update methods in action and manager.
i get this record with a new method called fetchRecord(long id) ..
how i get the result of this method if i dnt wanna use the request.setParameter in JSP and the action.
thank you in advanced for your reply.

Hi,Arden,
I guess you need to change the file ‘hibernate.cfg.xml’ as the connection parameters is incorrect,e.g. please confirm the username or password is right ,wish can help to you:)

Thank you for your project ! It is very useful for a learner.
I have download, deployed and run the project.

But I have find a BUG in this project, that is:
when I insert the contact, I get two repeated contacts every time.

I checked the code, and find in the execute() method of ContactAction.java,
there is not consistent with this weblog.
So I commented it and the problem disappears.

	public String execute() {
//		if(null != contact) {
//			linkController.add(getContact());
//		}
		this.contactList = linkController.list();
		System.out.println(contactList);
		System.out.println(contactList.size());
		return SUCCESS;
	}

Hi there just wanted to give you a quick heads up. The words in your post seem to be running off the screen in Opera.
I’m not sure if this is a format issue or something to do with internet browser compatibility but I thought I’d post to let you know.
The layout look great though! Hope you get the problem fixed
soon. Many thanks

– deleted old db driver and copied the new one.

Why? Miss to do some other changes?

Viral Patel 10 June, 2013, 15:28
You are getting this error because MySQL driver jar is not present in your classpath. I assume you dont want to run this example with MySQL. In that case you need to change the connection.driver_class and dialect properties in hibernate.cfg.xml file to appropriate driver class. Also the username/password and connection string needs to be modified accordingly. Only hibernate.cfg.xml file will be changed.
