jsf集成spring

本文介紹了如何使用JSF，PrimeFaces和Hibernate開發項目。 下面是一個示例應用程序：

二手技術：

JDK 1.6.0_21
Maven的3.0.2
JSF 2.0.3 PrimeFaces 2.2.1 Hibernate3.6.7 MySQL Java連接器5.1.17 MySQL 5.5.8 Apache Tomcat 7.0

第1步：創建用戶表

通過執行以下腳本來創建新的USER表：

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

步驟2：建立已完成的專案

創建一個Maven項目，如下所示。 （可以使用Maven或IDE插件創建）。

步驟3：圖書館

JSF，Hibernate和依賴庫添加到Maven的pom.xml中。 這些庫將由Maven中央存儲庫下載。

<!-- JSF library --> <dependency><groupId>com.sun.faces</groupId><artifactId>jsf-api</artifactId><version>2.0.3</version> </dependency> <dependency><groupId>com.sun.faces</groupId><artifactId>jsf-impl</artifactId><version>2.0.3</version> </dependency> <dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId><version>1.2</version> </dependency> <!-- Hibernate library --> <dependency><groupId>org.hibernate</groupId><artifactId>hibernate-core</artifactId><version>3.6.7.Final</version> </dependency> <dependency><groupId>javassist</groupId><artifactId>javassist</artifactId><version>3.12.1.GA</version> </dependency> <!-- MySQL Java Connector library --> <dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.17</version> </dependency> <!-- Log4j library --> <dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.16</version> </dependency>

注意：primefaces-2.2.1.jar也可以通過maven或以下鏈接下載：

<repository><id>prime-repo</id><name>PrimeFaces Maven Repository</name><url>http://repository.primefaces.org</url><layout>default</layout> </repository> <dependency><groupId>org.primefaces</groupId><artifactId>primefaces</artifactId><version>2.2.1</version> </dependency>

第4步：創建受管理的豆類

創建一個新的托管bean類。 使用了可以與UI組件關聯的bean。 托管Bean包含屬性以及getter和setter方法。 此外，它們還可以涵蓋事件處理，導航，驗證等方法。

package com.otv;import java.io.Serializable; import java.util.List;import org.apache.log4j.Logger; import org.hibernate.Session; import org.hibernate.Transaction;import com.otv.hbm.User; import com.otv.util.HibernateUtil;/*** @author onlinetechvision.com* @since 3 Oct 2011* @version 1.0.0**/ public class UserManagedBean implements Serializable{private static final long serialVersionUID = 1L;private static Logger log = Logger.getLogger(UserManagedBean.class);private static final String SUCCESS = 'success';private static final String ERROR = 'error';private String name;private String surname;private String message;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getSurname() {return surname;}public void setSurname(String surname) {this.surname = surname;}public String getMessage() {StringBuffer strBuff = new StringBuffer();strBuff.append('Name : ').append(this.getName());strBuff.append(', Surname : ').append(this.getSurname());this.setMessage(strBuff.toString());return this.message;}public void setMessage(String message) {this.message = message;} public String save() {String result = null;Session session = HibernateUtil.getSessionFactory().openSession();User user = new User();user.setName(this.getName());user.setSurname(this.getSurname());Transaction tx = null;try {tx = session.beginTransaction();session.save(user);tx.commit();log.debug('New Record : ' + user + ', wasCommitted : ' + tx.wasCommitted());result = SUCCESS;} catch (Exception e) {if (tx != null) {tx.rollback();result = ERROR;e.printStackTrace();}} finally {session.close();}return result;}public List<User> getUsers() {Session session = HibernateUtil.getSessionFactory().openSession();List<User> userList = session.createCriteria(User.class).list();return userList;}public void reset() {this.setName('');this.setSurname('');} }

步驟5：建立使用者類別

創建一個新的User類以對User Table建模。

package com.otv.hbm; /*** @author onlinetechvision.com* @since 3 Oct 2011* @version 1.0.0**/ public class User {private int id;private String name;private String surname;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 getSurname() {return surname;}public void setSurname(String surname) {this.surname = surname;} @Overridepublic String toString() {StringBuffer strBuff = new StringBuffer();strBuff.append('id : ').append(id);strBuff.append(', name : ').append(name);strBuff.append(', surname : ').append(surname);return strBuff.toString();} }

步驟6：建立新生兒類

創建Singleton HibernateUtil類以構建Hibernate SessionFactory對象。

package com.otv.util;import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration;/*** @author onlinetechvision.com* @since 3 Oct 2011* @version 1.0.0**/ public class HibernateUtil {private static SessionFactory sessionFactory = null;public static SessionFactory getSessionFactory() {if(sessionFactory == null) {sessionFactory = new Configuration().configure().buildSessionFactory();}return sessionFactory;}public static void setSessionFactory(SessionFactory sessionFactory) {HibernateUtil.sessionFactory = sessionFactory;}}

步驟7：創建index.xhtml

index.xhtml已創建。

<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.prime.com.tr/ui'> <h:head><title>Welcome to JSF_PrimeFaces_Hibernate Project</title></h:head><body><h:form><table><tr><td><h:outputLabel for='name' value='Name:' /></td><td><p:inputText id='name' value='#{userMBean.name}'/></td></tr><tr><td><h:outputLabel for='surname' value='Surname:' /></td><td><p:inputText id='surname' value='#{userMBean.surname}'/> </td></tr><tr><td><p:commandButton id='submit' value='Save' action='#{userMBean.save}' ajax='false'/></td><td><p:commandButton id='reset' value='Reset' action='#{userMBean.reset}' ajax='false'/></td></tr></table></h:form> </body> </html>

步驟8：建立welcome.xhtml

welcome.xhtml已創建。

<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.prime.com.tr/ui'><h:head><title>Welcome to JSF_PrimeFaces_Hibernate Project</title> </h:head> <body><h:form><h:outputText value='Saved Record is #{userMBean.message}'></h:outputText><p:dataTable id='users' value='#{userMBean.getUsers()}' var='user' 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> </body> </html>

步驟9：創建error.xhtml

error.xhtml已創建。

<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.prime.com.tr/ui'> <h:head><title>Welcome to JSF_PrimeFaces_Hibernate Project</title></h:head><body><f:view><h:form><h:outputText value='Transaction Error has occurred!'></h:outputText></h:form></f:view> </body> </html>

步驟10：配置faces-config.xml

faces-config.xml的創建如下。 它涵蓋了托管Bean的配置以及xhtml頁面之間的導航。

<?xml version='1.0' encoding='UTF-8'?> <faces-configxmlns='http://java.sun.com/xml/ns/javaee'xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'xsi:schemaLocation='http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd'version='2.0'><managed-bean><managed-bean-name>userMBean</managed-bean-name><managed-bean-class>com.otv.UserManagedBean</managed-bean-class><managed-bean-scope>request</managed-bean-scope></managed-bean><navigation-rule><from-view-id>/pages/index.xhtml</from-view-id><navigation-case><from-outcome>success</from-outcome><to-view-id>/pages/welcome.xhtml</to-view-id></navigation-case><navigation-case><from-outcome>error</from-outcome><to-view-id>/pages/error.xhtml</to-view-id></navigation-case></navigation-rule> </faces-config>

步驟11：更新web.xml

web.xml已更新。

<?xml version='1.0' encoding='UTF-8'?> <web-app xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'xmlns='http://java.sun.com/xml/ns/javaee'xmlns:web='http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd'xsi:schemaLocation='http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd'id='WebApp_ID'version='2.5'><display-name>OTV_JSF_PrimeFaces_Hibernate</display-name><context-param><param-name>javax.faces.PROJECT_STAGE</param-name><param-value>Development</param-value></context-param><welcome-file-list><welcome-file>/pages/index.xhtml</welcome-file></welcome-file-list><servlet><servlet-name>Faces Servlet</servlet-name><servlet-class>javax.faces.webapp.FacesServlet</servlet-class><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>Faces Servlet</servlet-name><url-pattern>/faces/*</url-pattern></servlet-mapping><servlet-mapping><servlet-name>Faces Servlet</servlet-name><url-pattern>*.jsf</url-pattern></servlet-mapping><servlet-mapping><servlet-name>Faces Servlet</servlet-name><url-pattern>*.faces</url-pattern></servlet-mapping><servlet-mapping><servlet-name>Faces Servlet</servlet-name><url-pattern>*.xhtml</url-pattern></servlet-mapping> </web-app>

步驟12：建立user.hbm.xml

用戶表配置已設置。

<?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='com.otv.hbm.User' table='USER'><id name='id' type='int' column='ID' ><generator class='increment'/></id><property name='name'><column name='NAME' /></property><property name='surname'><column name='SURNAME'/></property></class> </hibernate-mapping>

步驟13：建立hibernate.cfg.xml

創建hibernate.cfg.xml來管理應用程序和數據庫之間的交互：

<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-configuration PUBLIC'-//Hibernate/Hibernate Configuration DTD//EN''http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd'><hibernate-configuration> <session-factory><property name='hibernate.connection.driver_class'>com.mysql.jdbc.Driver</property><property name='hibernate.connection.url'>jdbc:mysql://localhost:3306/Test</property><property name='hibernate.connection.username'>root</property><property name='hibernate.connection.password'>root</property><property name='hibernate.connection.pool_size'>10</property><property name='show_sql'>true</property><property name='dialect'>org.hibernate.dialect.MySQLDialect</property><!-- Mapping files --><mapping resource='hbm/user.hbm.xml'/> </session-factory> </hibernate-configuration>

步驟14：將項目部署到應用程序服務器

將Project部署到Application Server（Apache tomcat）時，屏幕如下所示：

單擊提交按鈕后，將顯示welcome.xhtml頁面，如下所示：
