III. Create POJO class

package com.ant.pbacklog.model;

import java.io.Serializable;

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

@Entity
@Table(name = “UserStory”)
public class UserStory implements Serializable {
private static final long serialVersionUID = 1L;

@Id
@Column(name=”id”)
@GeneratedValue(strategy = GenerationType.SEQUENCE)
private Long userStoryId;

private String name;

@Column(nullable = false, length = 1000)
private String description;

@Column(nullable = false)
private int value;

private String status;
public Long getUserStoryId() {
return userStoryId;
}

public void setUserStoryId(Long userStoryId) {
this.userStoryId = userStoryId;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getDescription() {
return description;
}

public void setDescription(String description) {
this.description = description;
}

public int getValue() {
return value;
}

public void setValue(int value) {
this.value = value;
}

public String getStatus() {
return status;
}

public void setStatus(String status) {
this.status = status;
}
}

IV. Create mananged bean class

package com.ant.pbacklog.managedbean;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

import com.ant.pbacklog.model.UserStory;
import com.ant.pbacklog.service.UserStoryService;
@Component(“pblBean”)
@Scope(“session”)
public class ProducBacklogBean implements Serializable{

private static final long serialVersionUID = 1L;
private Long userStoryId;
private String name;
private String description;
private int value;
private String status;

private List<UserStory> usList;

public List<UserStory> getUsList() {
usList=new ArrayList<UserStory>();
usList=userStoryService.getAllUserStories();
return usList;
}
public void setUsList(List<UserStory> usList) {
this.usList = usList;
}
@Autowired
UserStoryService userStoryService;

public void addUserStory(){
UserStory us = new UserStory();
us.setName(getName());
us.setDescription(getDescription());
us.setStatus(getStatus());
us.setValue(getValue());
userStoryService.addUserStory(us);
}
public void delete(Long userStoryId){
userStoryService.deleteUserStory(userStoryId);
}
public Long getUserStoryId() {
return userStoryId;
}
public void setUserStoryId(Long userStoryId) {
this.userStoryId = userStoryId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}

}

V. Create classes for Bussiness Logic Layer

package com.ant.pbacklog.service;

import java.util.List;

import com.ant.pbacklog.model.UserStory;

public interface UserStoryService {

public void addUserStory(UserStory us) ;

public void deleteUserStory(Long userStoryId);

public List<UserStory> getAllUserStories() ;

}

—-

package com.ant.pbacklog.service;

import java.io.Serializable;

import java.util.List;

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

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional;

import com.ant.pbacklog.dao.UserStoryDao;

import com.ant.pbacklog.model.UserStory;

@Service

@Transactional

public class UserStoryServiceImpl implements UserStoryService,Serializable {

private static final long serialVersionUID = 1L;

@Autowired

UserStoryDao userStoryDao;

public void addUserStory(UserStory us) {

userStoryDao.addUserStory(us);

}

public void deleteUserStory(Long userStoryId) {

userStoryDao.deleteUserStory(userStoryId);

}

public List<UserStory> getAllUserStories() {

return userStoryDao.getUserStories();

}

}

VI. Create classes for Data Access Layer

package com.ant.pbacklog.dao;

import java.util.List;

import com.ant.pbacklog.model.UserStory;

public interface UserStoryDao {

public void addUserStory(UserStory us);

public void deleteUserStory(Long userStoryId);

public List<UserStory> getUserStories();

}

package com.ant.pbacklog.dao;

import java.io.Serializable;
import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.ant.pbacklog.model.UserStory;

@Repository(“userStoryDao”)
@Transactional
public class UserStoryDaoImpl implements UserStoryDao, Serializable{

private static final long serialVersionUID = 1L;

@Autowired
private SessionFactory sessionFactory;

public void addUserStory(UserStory us) {
Session session = sessionFactory.getCurrentSession();
session.save(us);

}

public void deleteUserStory(Long userStoryId) {
UserStory userStory = (UserStory) sessionFactory.getCurrentSession().load(UserStory.class, userStoryId);
if(userStory != null){
sessionFactory.getCurrentSession().delete(userStory);
}

}

@SuppressWarnings(“unchecked”)
public List<UserStory> getUserStories() {
Session session = sessionFactory.getCurrentSession();
List<UserStory> list = null;
try{
list = session.createQuery(“from UserStory”).list();
}
catch(HibernateException e){
e.printStackTrace();
}
return list;
}

}
