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.

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. ADS_TO_REPLACE_41

package roseindia.model;

import java.io.Serializable;

import java.sql.Date;ADS_TO_REPLACE_42

import javax.persistence.Column;

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;ADS_TO_REPLACE_43

import javax.persistence.Id;

import javax.persistence.Table;

@EntityADS_TO_REPLACE_44

@Table(name = "Register")

public class Register implements Serializable {

private static final long serialVersionUID = -6430275524165380638L;ADS_TO_REPLACE_45

private Long id;

private String name;

return birthDate;ADS_TO_REPLACE_63

}

public void setBirthDate(Date birthDate) {

this.birthDate = birthDate;ADS_TO_REPLACE_64

}

}

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;ADS_TO_REPLACE_65

import roseindia.dao.HibernateUtil;

import roseindia.model.Register;

import org.hibernate.Session;ADS_TO_REPLACE_66

import org.hibernate.SessionFactory;

import org.hibernate.Transaction;

public class RegisterDao {ADS_TO_REPLACE_67

public static boolean registerUser(Register Rgst) {

                   SessionFactory sf = HibernateUtil.getSessionFactory();

                 Transaction t = null;ADS_TO_REPLACE_68

         try {

                       Session s = sf.openSession();

                      t = s.beginTransaction(); // start a new transaction ADS_TO_REPLACE_69

                     s.persist(Rgst);

                      t.commit(); // commit transaction

                         return true;ADS_TO_REPLACE_70

              } catch (Exception ex) {

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

           if (t != null)ADS_TO_REPLACE_71

                    t.rollback();

                   return false;

         }ADS_TO_REPLACE_72

}

}

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;ADS_TO_REPLACE_73

import org.hibernate.cfg.AnnotationConfiguration;

import org.hibernate.SessionFactory;

public class HibernateUtil {ADS_TO_REPLACE_74

private static final SessionFactory sessionFactory;

static {

try {ADS_TO_REPLACE_75

sessionFactory = new AnnotationConfiguration().configure()

.buildSessionFactory();

} catch (Throwable ex) {ADS_TO_REPLACE_76

System.err.println("Initial SessionFactory creation failed." + ex);

throw new ExceptionInInitializerError(ex);

}ADS_TO_REPLACE_77

}

public static SessionFactory getSessionFactory() {

return sessionFactory;ADS_TO_REPLACE_78

}

}

8 package.properties

requiredstring = ${getText(fieldName)} is required. ADS_TO_REPLACE_79

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

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

requiredinteger = ${getText(fieldName)} should be numeric. ADS_TO_REPLACE_80

password = Password

name = Name

emailId = Email Address ADS_TO_REPLACE_81

website = Website

cellNo = CellNo

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

<?xml version="1.0" encoding="UTF-8" ?>ADS_TO_REPLACE_82

<!DOCTYPE struts PUBLIC

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

                                                   "http://struts.apache.org/dtds/struts-2.0.dtd">ADS_TO_REPLACE_83

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

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

</action>ADS_TO_REPLACE_86

</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'?>ADS_TO_REPLACE_87
