Java Frameworks: STRUTS 2 HIBERNATE INTEGRATION EXAMPLE

The following software are used :

Steps for integration on Struts2 and Hibernate

Step 1: Create homepage

Step 2: Create struts and web xml file

Step 3: Create Action/POJO class and mapping file

Step 4: Create hibernate.cfg.xml &hbm file

Step 5: Create success and failure page

Step1: home.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"

pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<%@ taglib uri="/struts-tags" prefix="s" %>

<s:form name="frm" action="reg">

Name<s:textfield name="name"/>

Password<s:password name="pwd"/>

City<s:textfield name="city"/>

Phone No:<s:textfield name="pno"/>

Email:<s:textfield name="email"/>

<s:submit value="Register"></s:submit>

</s:form>

Step 2: struts.xml

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

<!DOCTYPE struts PUBLIC "-//Apache Software Foundation

//DTD Struts Configuration 2.1//EN"

"http://struts.apache.org/dtds/struts-2.1.dtd">

</action> </package> </struts>

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
<welcome-file-list>
<welcome-file>home.jsp</welcome-file>
</welcome-file-list>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

</web-app>

Step 3: Register.java

public class Register

{

private String name,pwd,city,email;

private int pno;

//create getter and setter here

public void execute()

{

}}

Step 4: Login.java

import org.hibernate.Session;

import org.hibernate.Transaction;

import org.hibernate.cfg.Configuration;

public class Login

{ public static void send(Register obj)

{try{

Session session=new Configuration().configure("hibernate.cfg.xml").buildSessionFactory().openSession();

Transaction t=session.beginTransaction();

//Get and set the values

String name=obj.getName();

obj.setName(name);

String pwd=obj.getPwd();

obj.setPwd(pwd);

String city=obj.getCity();

obj.setCity(city);

int pno=obj.getPno();

obj.setPno(pno);

String email=obj.getEmail();

obj.setEmail(email);

session.save(obj);

t.commit();

session.close();

System.out.println("successfully saved");

}catch(Exception e){System.out.println(e);}}}

Step 5: Create hibernate.cfg.xml & tablename.hbm.xml

hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping resource="Register.hbm.xml"/>
</session-factory></hibernate-configuration>

Register.hbm.xml

<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="Register" table="REGISTER"> <id name="pno" type="int"> <column name="PNO" /> <generator class="assigned" /> </id> <property name="name" type="java.lang.String"> <column name="NAME" /> </property> <property name="pwd" type="java.lang.String"> <column name="PWD" /> </property> <property name="city" type="java.lang.String"> <column name="CITY" /> </property> <property name="email" type="java.lang.String"> <column name="EMAIL" /> </property> </class></hibernate-mapping>
