Struts2.2.1 Hibernate Example

In this example, We will discuss about the Hibernate Integration using struts2.2.1. In this example,we take the input from the user by a form add save the detail in the database using hibernate.The action mapping is in the struts.xml file.

Directory structure and jars used in the example.

4-RegisterAction.java

package roseindia.view;

import java.sql.Date;

import roseindia.dao.RegisterDao;

import roseindia.model.Register;

import com.opensymphony.xwork2.ActionSupport;

public class RegisterAction extends ActionSupport {

private static final long serialVersionUID = 908606616890722294L;

private String emailId, password, name, cellNo, website;

private Date birthDate;

private Long id;

public Long getId() {

return id;

}

public void setId(Long id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getCellNo() {

return cellNo;

}

public void setCellNo(String cellNo) {

this.cellNo = cellNo;

}

public String getWebsite() {

return website;

}

public void setWebsite(String website) {

this.website = website;

}

public Date getBirthDate() {

return birthDate;

}

public void setBirthDate(Date birthDate) {

this.birthDate = birthDate;

}

public String getEmailId() {

return emailId;

}

public void setEmailId(String emailId) {

this.emailId = emailId;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public RegisterAction() {

}

public String execute() throws Exception {

Rgst.setCellNo(cellNo);

Rgst.setWebsite(website);

Rgst.setBirthDate(birthDate);

Rgst.setEmailId(emailId);

Rgst.setName(name);

Rgst.setPassword(password);

if (RegisterDao.registerUser(Rgst))

return "success";

else

return "fail";

}

5 -Register.java - This class is used to mapped the Register table in the Mysql database, we use the annotation to provide metadata to the class and fields of the table.

package roseindia.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 = "Register")

public class Register implements Serializable {

private static final long serialVersionUID = -6430275524165380638L;

private Long id;

private String name;

private String emailId;

private String password;

private String cellNo;

private String website;

private Date birthDate;

@Id

@GeneratedValue

@Column(name = "id")

public Long getId() {

return id;

}

public void setId(Long id) {

this.id = id;

}

@Column(name = "name")

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

@Column(name = "emailId")

public String getEmailId() {

return emailId;

}

public void setEmailId(String emailId) {

this.emailId = emailId;

}

@Column(name = "password")

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

@Column(name = "cellNo")

public String getCellNo() {

return cellNo;

}

public void setCellNo(String cellNo) {

this.cellNo = cellNo;

}

@Column(name = "website")

public String getWebsite() {

return website;

}

public void setWebsite(String website) {

this.website = website;

}

@Column(name = "birthDate")

public Date getBirthDate() {

return birthDate;

}

public void setBirthDate(Date birthDate) {

this.birthDate = birthDate;

}

6 - RegisterDao.java - This class is based on DAO (Data Access Object ) design pattern and used for accessing the hibernate from action.

package roseindia.dao;

import roseindia.dao.HibernateUtil;

import roseindia.model.Register;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.hibernate.Transaction;

public class RegisterDao {

public static boolean registerUser(Register Rgst) {

SessionFactory sf = HibernateUtil.getSessionFactory();

Transaction t = null;

try {

Session s = sf.openSession();

t = s.beginTransaction(); // start a new transaction

s.persist(Rgst);

t.commit(); // commit transaction

return true;

} catch (Exception ex) {

System.err.println("Error -->" + ex.getMessage());

if (t != null)

t.rollback();

return false;

}

7 - HibernateUtil.java - This class creates the SessionFactory object and return it. The method AnnotationConfiguration() is used to get the support of annotation for hibernate.

package roseindia.dao;

import org.hibernate.cfg.AnnotationConfiguration;

import org.hibernate.SessionFactory;

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {

try {

sessionFactory = 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;

}

8 package.properties

requiredstring = ${getText(fieldName)} is required.

requiredemail = ${getText(fieldName)} is not in correct format.

requiredpassword = ${getText(fieldName)} should be more than 6 character.

requiredinteger = ${getText(fieldName)} should be numeric.

password = Password

name = Name

emailId = Email Address

website = Website

cellNo = CellNo

9 struts.xml - In this file we do the action mapping.

<?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">

<result name="input">/SignUp.jsp</result>

<result name="success">/SignUpSuccess.jsp</result>

<result name="fail">/SignUpFail.jsp</result>

</action>

</package>

</struts>

10 hibernate.cfg.xml - The hibernate.cfg.xml file is hibernate configuration file and it is used to configure the Register table in the gyan database.

<?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
