本文介绍了一个JSF、Spring和Hibernate框架整合的示例项目搭建过程，包括了从创建Web工程到实现登录功能的具体步骤。涵盖JSF、Spring、Hibernate等组件的配置与使用。

说三分钟是对于熟练手来说，但本质于对于建立一个框架还要有其他很多的工程如util,common。模块xml配置，以及还要应对那些模块整合所带来的一些冲突，解决这些可不是一件好玩的事。最好是多做一下全量备份或者版本控制，以免出了问题无法找到原因或者也无法还原。

好了，下面开始吧.

建立web工程就不用说了，

1.add jsf: 工程右键->myeclipse->add jsf capabilities 可以选择MyFaces 1.1.1或者MyFaces 0.xx版本，后面弹出的是就OK。这里如果是选择Sun JSF Reference Implementation xxx版本时会出现一包问题，这是JAR包的冲突问题，如果有谁在此版本上实现了在jsf配置文件能够注入bean的请告诉我。。。。

2.add spring:工程右键->myeclipse->add Spring capabilities.

3.add hibernate:工程右键->myeclipse ->add hibernate capabilites。hibernate配置可以引用spring的配置文件，当然你可以利用hibernate.hbm.xml来配置你的工程，再引入一下dataSource的DB连接，后面的"create SessionFacotry class"就不用建立，如果你有用到也可以建立。

4.利用hibernate工具生成

UserTable.java

UserTable.hbm.xml

这两个文件

5.建立dao,service的接口及其实现类或者麻烦点再加个ucc

dao:

public interface UserDao {
	public UserTable getUser(String username);
}


public class UserDaoImpl extends HibernateDaoSupport implements UserDao{

	public UserTable getUser(String username) {
		UserTable user=(UserTable)getHibernateTemplate().get(UserTable.class, username);
		return user;
	}

}

bs:

public interface UserService {
	public UserTable getUser(String username);
}
public class UserServiceImpl implements UserService{
	private UserDao userDao;
	public UserTable getUser(String username) {
		// TODO Auto-generated method stub
		return userDao.getUser(username);
	}
	public UserDao getUserDao() {
		return userDao;
	}
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

}

6.配置spring把刚才建立的这几个dao,service,ucc相应的bean设置进去

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName">
			<value>oracle.jdbc.driver.OracleDriver</value>
		</property>
		<property name="url">
			<value>jdbc:oracle:thin:@localhost:1521:oracle</value>
		</property>
		<property name="username">
			<value>test</value>
		</property>
		<property name="password">
			<value>test</value>
		</property>
	</bean>
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.Oracle9Dialect
				</prop>
			</props>
		</property>
		<property name="mappingResources">
			<list>
				<value>com/lgh/hibernate/UserTable.hbm.xml</value>
			</list>
		</property>
	</bean>
	
	
	<bean id="userDao" class="com.lgh.test.dao.UserDaoImpl">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>
	<!-- -->
	<bean id="userService" class="com.lgh.test.service.UserServiceImpl">
		<property name="userDao">
			<ref bean="userDao" />
		</property>
	</bean>

	
	
	
	
	</beans>

7.设置的bean容器怎么初始化呢？配置我们的xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
  <!-- spring  加载bean -->
  <servlet>
		<servlet-name>context</servlet-name>
		<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
  <context-param>
    <param-name>javax.faces.CONFIG_FILES</param-name>
    <param-value>/WEB-INF/faces-config.xml</param-value>
  </context-param>
  <!-- jsf 加载 -->
  <listener>
    <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
  </listener>
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.faces</url-pattern>
  </servlet-mapping>
</web-app>

8.jsp页面及对应的BackingBean就是(bb啦),jsf配置文件(faces-config.xml)

face-config.xml配置manage-bean导航

<?xml version="1.0" encoding="UTF-8"?>   
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">   
   
<faces-config>   
    <application>   
        <variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>   
    </application>   
    <managed-bean>
		<managed-bean-name>UserLoginBB</managed-bean-name>
		<managed-bean-class>
			com.lgh.test.ucc.UserLoginBB
		</managed-bean-class>
		<managed-bean-scope>request</managed-bean-scope>
		<managed-property>
			<property-name>username</property-name>
			<property-class>java.lang.String</property-class>
			<value></value>
		</managed-property>
		<managed-property>
			<property-name>password</property-name>
			<property-class>java.lang.String</property-class>
			<value></value>
		</managed-property>
		<!--  -->

		<managed-property>
			<property-name>userService</property-name>
			<value>#{userService}</value>
		</managed-property>

	</managed-bean>
</faces-config>

登录的页面:

<f:view>
			<h:form rendered="true" id="loginForm">
				<h:inputText required="false" rendered="true"
					value="#{UserLoginBB.username}"></h:inputText>
				<br>
				<h:inputText required="false" rendered="true"
					value="#{UserLoginBB.password}">
				<br>
				</h:inputText>
				<br>
				<h:commandButton action="#{UserLoginBB.userLogin}" rendered="true"
					value="登录"></h:commandButton>
				
			</h:form>
		</f:view>

它所对应的BB：

public class UserLoginBB {
	private UserService userService;
	private String username;
	private String password;
	public String userLogin(){
		//方法一
//		ApplicationContext context=FacesContextUtils.getWebApplicationContext(FacesContext.getCurrentInstance());
//		UserService service = (UserService)context.getBean("userService");
//		UserTable user = service.getUser("Hibernate1");
		//方法二？？采用manager-bean来配置userService
		UserTable user = userService.getUser("Hibernate1");
		System.out.println("hello"+user.getPassword());
		return user.getPassword();			
	}
	
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}

	public UserService getUserService() {
		return userService;
	}

	public void setUserService(UserService userService) {
		this.userService = userService;
	}
	
	
}
