Spring jsf Hibernate Integration
Hello Friends.i am going to demonstrate you Spring Hibernate jsf integration project.here in this example i am follwing DAO pattern to interact with database.
You need to add jars associated with spring ,hibernate and jsf .
As it does not include any thorough understanding the concept i am moving towards code ,the code is as given below :
Java/Reources->org.integration.model
package org.integration.model;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table
public class User
{
@Id
private int id;
@Column(nullable=false)
private String username;
@Column(nullable=false)
private String password;
public int getId()
{
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
under Java Resources->org.integration.dao
package org.integration.dao;
import org.integration.model.User;
public interface UserDao
{
public void addUser(User u);
public void updateUser(int id);
public void deleteUser(int id);
}
under Java Resources->org.integration.dao
package org.integration.dao;
import org.hibernate.SessionFactory;
import org.integration.model.User;
public class UserDaoImpl implements UserDao
{
private SessionFactory sessionfactory;
public SessionFactory getSessionfactory() {
return sessionfactory;
}
public void setSessionfactory(SessionFactory sessionfactory) {
this.sessionfactory = sessionfactory;
}
@Override
public void addUser(User u)
{
getSessionfactory().getCurrentSession().save(u);
}
@Override
public void updateUser(int id)
{
getSessionfactory().getCurrentSession().update(id);
}
@Override
public void deleteUser(int id)
{
getSessionfactory().getCurrentSession().delete(id);
}
}
under Java Resources->org.integration.service
package org.integration.service;
import org.integration.model.User;
public interface UserService
{
public void addUser(User u);
public void updateUser(int id);
public void deleteUser(int id);
}
under Java Resources->org.integration.service
package org.integration.service;
import org.integration.dao.UserDao;
import org.integration.model.User;
public class UserServiceImpl implements UserService
{
private UserDao userDAO;
public UserDao getUserDAO() {
return userDAO;
}
public void setUserDAO(UserDao userDAO)
{
this.userDAO = userDAO;
}
@Override
public void addUser(User u)
{
getUserDAO().addUser(u);
}
@Override
public void updateUser(int id)
{
getUserDAO().updateUser(id);
}
@Override
public void deleteUser(int id)
{
getUserDAO().deleteUser(id);
}
}
under Java Resources->org.integration.beanManager
package org.integration.beanManager;
import java.io.Serializable;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import org.integration.model.User;
import org.integration.service.UserService;
import org.springframework.dao.DataAccessException;
@ManagedBean
public class UserHandler implements Serializable
{
/**
*
*/
private static final long serialVersionUID = 1L;
@ManagedProperty(value = "#{userservice}")
private UserService userservice;
private int id;
private String name;
private String password;
public UserHandler()
{
}
public UserService getUserservice() {
return userservice;
}
public void setUserservice(UserService userservice) {
this.userservice = userservice;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String add()
{
try
{
User u=new User();
u.setId(getId());
u.setUsername(getName());
u.setPassword(getPassword());
getUserservice().addUser(u);
}
catch(DataAccessException d)
{
}
return "Success";
}
public String update(int id)
{
getUserservice().updateUser(id);
return "Update";
}
public String delete(int id)
{
getUserservice().deleteUser(id);
return "Delete";
}
}

[Note: example only demonstrates to add user daa,it does not associated any ui component with action event such as update, delete]
hope you will get my point
thanks
