本文展示了如何集成JSF2，PrimeFaces3，Spring3和Hibernate4技術(shù)。 它為Java開(kāi)發(fā)人員提供了一個(gè)通用的項(xiàng)目模板。

另外，如果Spring不用于業(yè)務(wù)和數(shù)據(jù)訪問(wèn)層，則可以提供JSF – PrimeFaces和Hibernate集成項(xiàng)目。

二手技術(shù)：

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

步驟1：建立已完成的專案

創(chuàng)建一個(gè)Maven項(xiàng)目，如下所示。 （可以使用Maven或IDE插件來(lái)創(chuàng)建它）。

第2步：創(chuàng)建用戶表

通過(guò)執(zhí)行以下腳本來(lái)創(chuàng)建新的用戶表：

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

步驟3：圖書館

Spring，JSF，Hibernate，Primefaces，MySQL和c3p0依賴項(xiàng)已添加到Maven的pom.xml中。

<properties><spring.version>3.1.1.RELEASE</spring.version></properties><dependencies><!-- Spring 3 dependencies --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>${spring.version}</version></dependency> <dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${spring.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>${spring.version}</version></dependency><!-- JSF dependencies --><dependency><groupId>com.sun.faces</groupId><artifactId>jsf-api</artifactId><version>2.1.6</version></dependency><dependency><groupId>com.sun.faces</groupId><artifactId>jsf-impl</artifactId><version>2.1.6</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><!-- Primefaces dependency --><dependency><groupId>org.primefaces</groupId><artifactId>primefaces</artifactId><version>3.1.1</version></dependency><!-- Hibernate dependencies --><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-core</artifactId><version>4.1.0.Final</version></dependency><dependency><groupId>javassist</groupId><artifactId>javassist</artifactId><version>3.12.1.GA</version></dependency><!-- MySQL Java Connector dependency --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.17</version></dependency><!-- c3p0 dependency --><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>0.9.1.2</version></dependency> </dependencies>

步驟4：建立使用者模型類別

創(chuàng)建一個(gè)新的用戶模型類。

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：創(chuàng)建用戶管理的豆類

用戶托管Bean已創(chuàng)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;}}

步驟6：建立IUserDAO介面

IUserDAO接口提供了數(shù)據(jù)訪問(wèn)層的方法。 數(shù)據(jù)訪問(wèn)層管理所有邏輯以持久化并從數(shù)據(jù)庫(kù)檢索數(shù)據(jù)。

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：創(chuàng)建UserDAO類

通過(guò)實(shí)現(xiàn)IUserDAO接口創(chuàng)建UserDAO類。

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;}}

步驟8：建立IUserService介面

IUserService接口提供了處理業(yè)務(wù)邏輯的方法。

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(); }

步驟9：創(chuàng)建UserService類

通過(guò)實(shí)現(xiàn)IUserService接口創(chuàng)建UserService類。

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;} }

步驟10：創(chuàng)建applicationContext.xml

Spring Application Context的內(nèi)容如下所示：

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:tx="http://www.springframework.org/schema/tx"xmlns:context="http://www.springframework.org/schema/context"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd"><!-- Beans Declaration --><bean id="User" class="com.otv.model.User"/><!-- User Service Declaration --><bean id="UserService" class="com.otv.user.service.UserService"><property name="userDAO" ref="UserDAO" /></bean><!-- User DAO Declaration --><bean id="UserDAO" class="com.otv.user.dao.UserDAO"><property name="sessionFactory" ref="SessionFactory" /></bean><!-- Data Source Declaration --><bean id="DataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"><property name="driverClass" value="com.mysql.jdbc.Driver" /><property name="jdbcUrl" value="jdbc:mysql://localhost:3306/Test" /><property name="user" value="root" /><property name="password" value="root" /><property name="maxPoolSize" value="10" /><property name="maxStatements" value="0" /><property name="minPoolSize" value="5" /></bean><!-- Session Factory Declaration --><bean id="SessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"><property name="dataSource" ref="DataSource" /><property name="annotatedClasses"><list><value>com.otv.model.User</value></list></property><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop></props></property></bean><!-- Enable the configuration of transactional behavior based on annotations --><tx:annotation-driven transaction-manager="txManager"/><!-- Transaction Manager is defined --><bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"><property name="sessionFactory" ref="SessionFactory"/></bean></beans>

步驟11：創(chuàng)建faces-config.xml

步驟13：建立index.xhtml

index.xhtml創(chuàng)建如下：

<html xmlns="http://www.w3.org/1999/xhtml"xmlns:h="http://java.sun.com/jsf/html"xmlns:f="http://java.sun.com/jsf/core"xmlns:p="http://primefaces.org/ui"><h:head><title>Welcome to OTV_JSF_Spring_Hibernate_Project</title></h:head><h:body><h:form><table><tr><td><h:outputLabel for="id" value="Id : " /></td><td><p:inputText id="id" value="#{userMB.id}"><f:converter converterId="javax.faces.Integer"/><p:ajax event="blur" update="idMsg" /></p:inputText><p:message id="idMsg" for="id" display="icon"/></td></tr><tr><td><h:outputLabel for="name" value="Name : " /></td><td><p:inputText id="name" value="#{userMB.name}"><f:validateLength minimum="5" /><p:ajax event="blur" update="nameMsg" /></p:inputText><p:message id="nameMsg" for="name" display="icon"/></td></tr><tr><td><h:outputLabel for="surname" value="Surname : " /></td><td><p:inputText id="surname" value="#{userMB.surname}"><f:validateLength minimum="5" /><p:ajax event="blur" update="surnameMsg" /></p:inputText><p:message id="surnameMsg" for="surname" display="icon"/></td></tr><tr><td><p:commandButton id="addUser" value="Add" action="#{userMB.addUser}" ajax="false"/></td><td><p:commandButton id="reset" value="Reset" action="#{userMB.reset}" ajax="false"/></td></tr></table></h:form> </h:body> </html>

步驟14：創(chuàng)建success.xhtml

success.xhtml創(chuàng)建如下：

<html xmlns="http://www.w3.org/1999/xhtml"xmlns:h="http://java.sun.com/jsf/html"xmlns:f="http://java.sun.com/jsf/core"xmlns:p="http://primefaces.org/ui"> <h:head><title>Welcome to OTV_JSF_Spring_Hibernate_Project</title> </h:head> <h:body><h:form><h:outputText value="USERs : "></h:outputText><p:dataTable id="users" var="user" value="#{userMB.userList}" style="width: 10%"><p:column><f:facet name="header"><h:outputText value="ID" /></f:facet><h:outputText value="#{user.id}" /></p:column><p:column><f:facet name="header"><h:outputText value="Name" /></f:facet><h:outputText value="#{user.name}" /></p:column><p:column><f:facet name="header"><h:outputText value="Surname" /></f:facet><h:outputText value="#{user.surname}" /></p:column></p:dataTable></h:form> </h:body></html>
