JSF 2，PrimeFaces 3，Spring 3和Hibernate 4集成项目

本文展示了如何集成JSF2，PrimeFaces3，Spring3和Hibernate4技术。它为Java开发人员提供了一个通用的项目模板。

另外，如果Spring不用于业务和数据访问层，则可以提供JSF – PrimeFaces和Hibernate集成项目。

二手技术：

JDK 1.6.0_31
春天3.1.1
JSF 2.1
休眠4.1.0
Primefaces 3.1.1
MySQL连接器5.1.17
MySQL 5.5.8
c3p0 0.9.1.2
Tomcat 7.0
Maven的3.0.2

步骤1：建立已完成的专案

创建一个Maven项目，如下所示。（可以使用Maven或IDE插件来创建它）。

第2步：创建用户表

通过执行以下脚本来创建新的用户表：

CREATE TABLE USER (id int(11) NOT NULL,name varchar(45) NOT NULL,surname varchar(45) NOT NULL,PRIMARY KEY (`id`)
);

步骤3：图书馆

Spring，JSF，Hibernate，Primefaces，MySQL和c3p0依赖项已添加到Maven的pom.xml中。

步骤4：建立使用者模型类别

创建一个新的用户模型类。

package com.otv.model;import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;/**** User Entity** @author onlinetechvision.com* @since 25 Mar 2012* @version 1.0.0**/
@Entity
@Table(name="USER")
public class User {private int id;private String name;private String surname;/*** Get User Id** @return int - User Id*/@Id@Column(name="ID", unique = true, nullable = false)public int getId() {return id;}/*** Set User Id** @param int - User Id*/public void setId(int id) {this.id = id;}/*** Get User Name** @return String - User Name*/@Column(name="NAME", unique = true, nullable = false)public String getName() {return name;}/*** Set User Name** @param String - User Name*/public void setName(String name) {this.name = name;}/*** Get User Surname** @return String - User Surname*/@Column(name="SURNAME", unique = true, nullable = false)public String getSurname() {return surname;}/*** Set User Surname** @param String - User Surname*/public void setSurname(String surname) {this.surname = surname;} @Overridepublic String toString() {StringBuffer strBuff = new StringBuffer();strBuff.append("id : ").append(getId());strBuff.append(", name : ").append(getName());strBuff.append(", surname : ").append(getSurname());return strBuff.toString();}
}

第5步：创建用户管理的豆类

用户托管Bean已创建。

package com.otv.managed.bean;import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.RequestScoped;import org.springframework.dao.DataAccessException;import com.otv.model.User;
import com.otv.user.service.IUserService;/**** User Managed Bean** @author onlinetechvision.com* @since 25 Mar 2012* @version 1.0.0**/
@ManagedBean(name="userMB")
@RequestScoped
public class UserManagedBean implements Serializable {private static final long serialVersionUID = 1L;private static final String SUCCESS = "success";private static final String ERROR   = "error";//Spring User Service is injected...@ManagedProperty(value="#{UserService}")IUserService userService;List<User> userList;private int id;private String name;private String surname;/*** Add User** @return String - Response Message*/public String addUser() {try {User user = new User();user.setId(getId());user.setName(getName());user.setSurname(getSurname());getUserService().addUser(user);return SUCCESS;} catch (DataAccessException e) {e.printStackTrace();}  return ERROR;}/*** Reset Fields**/public void reset() {this.setId(0);this.setName("");this.setSurname("");}/*** Get User List** @return List - User List*/public List<User> getUserList() {userList = new ArrayList<User>();userList.addAll(getUserService().getUsers());return userList;}/*** Get User Service** @return IUserService - User Service*/public IUserService getUserService() {return userService;}/*** Set User Service** @param IUserService - User Service*/public void setUserService(IUserService userService) {this.userService = userService;}/*** Set User List** @param List - User List*/public void setUserList(List<User> userList) {this.userList = userList;}/*** Get User Id** @return int - User Id*/public int getId() {return id;}/*** Set User Id** @param int - User Id*/public void setId(int id) {this.id = id;}/*** Get User Name** @return String - User Name*/public String getName() {return name;}/*** Set User Name** @param String - User Name*/public void setName(String name) {this.name = name;}/*** Get User Surname** @return String - User Surname*/public String getSurname() {return surname;}/*** Set User Surname** @param String - User Surname*/public void setSurname(String surname) {this.surname = surname;}}

步骤6：建立IUserDAO介面

IUserDAO接口提供了数据访问层的方法。数据访问层管理所有逻辑以持久化并从数据库检索数据。

package com.otv.user.dao;import java.util.List;import com.otv.model.User;/**** User DAO Interface** @author onlinetechvision.com* @since 25 Mar 2012* @version 1.0.0**/
public interface IUserDAO {/*** Add User** @param  User user*/public void addUser(User user);/*** Update User** @param  User user*/public void updateUser(User user);/*** Delete User** @param  User user*/public void deleteUser(User user);/*** Get User** @param  int User Id*/public User getUserById(int id);/*** Get User List**/public List<User> getUsers();
}

第7步：创建UserDAO类

通过实现IUserDAO接口创建UserDAO类。

package com.otv.user.dao;import java.util.List;import com.otv.model.User;import org.hibernate.SessionFactory;/**** User DAO** @author onlinetechvision.com* @since 25 Mar 2012* @version 1.0.0**/public class UserDAO implements IUserDAO {private SessionFactory sessionFactory;/*** Get Hibernate Session Factory** @return SessionFactory - Hibernate Session Factory*/public SessionFactory getSessionFactory() {return sessionFactory;}/*** Set Hibernate Session Factory** @param SessionFactory - Hibernate Session Factory*/public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}/*** Add User** @param  User user*/@Overridepublic void addUser(User user) {getSessionFactory().getCurrentSession().save(user);}/*** Delete User** @param  User user*/@Overridepublic void deleteUser(User user) {getSessionFactory().getCurrentSession().delete(user);}/*** Update User** @param  User user*/@Overridepublic void updateUser(User user) {getSessionFactory().getCurrentSession().update(user);}/*** Get User** @param  int User Id* @return User*/@Overridepublic User getUserById(int id) {List list = getSessionFactory().getCurrentSession().createQuery("from User where id=?").setParameter(0, id).list();return (User)list.get(0);}/*** Get User List** @return List - User list*/@Overridepublic List<User> getUsers() {List list = getSessionFactory().getCurrentSession().createQuery("from User").list();return list;}}

步骤8：建立IUserService介面

IUserService接口提供了处理业务逻辑的方法。

package com.otv.user.service;import java.util.List;import com.otv.model.User;/**** User Service Interface** @author onlinetechvision.com* @since 25 Mar 2012* @version 1.0.0**/
public interface IUserService {/*** Add User** @param  User user*/public void addUser(User user);/*** Update User** @param  User user*/public void updateUser(User user);/*** Delete User** @param  User user*/public void deleteUser(User user);/*** Get User** @param  int User Id*/public User getUserById(int id);/*** Get User List** @return List - User list*/public List<User> getUsers();
}

步骤9：创建UserService类

通过实现IUserService接口创建UserService类。

package com.otv.user.service;import java.util.List;import org.springframework.transaction.annotation.Transactional;import com.otv.model.User;
import com.otv.user.dao.IUserDAO;/**** User Service** @author onlinetechvision.com* @since 25 Mar 2012* @version 1.0.0**/
@Transactional(readOnly = true)
public class UserService implements IUserService {// UserDAO is injected...IUserDAO userDAO;/*** Add User** @param  User user*/@Transactional(readOnly = false)@Overridepublic void addUser(User user) {getUserDAO().addUser(user);}/*** Delete User** @param  User user*/@Transactional(readOnly = false)@Overridepublic void deleteUser(User user) {getUserDAO().deleteUser(user);}/*** Update User** @param  User user*/@Transactional(readOnly = false)@Overridepublic void updateUser(User user) {getUserDAO().updateUser(user);}/*** Get User** @param  int User Id*/@Overridepublic User getUserById(int id) {return getUserDAO().getUserById(id);}/*** Get User List**/@Overridepublic List<User> getUsers() {return getUserDAO().getUsers();}/*** Get User DAO** @return IUserDAO - User DAO*/public IUserDAO getUserDAO() {return userDAO;}/*** Set User DAO** @param IUserDAO - User DAO*/public void setUserDAO(IUserDAO userDAO) {this.userDAO = userDAO;}
}

步骤10：创建applicationContext.xml
