实体类的简单参考，person中有一些event，一对多的关系
Event.java：

package com.chinaforwards.niagara.ems.jpa;

import java.io.Serializable;
import java.util.Date;
import java.util.HashSet;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToOne;
import javax.persistence.UniqueConstraint;

@Entity
public class Event implements Serializable {

	private static final long serialVersionUID = 1L;
    private long id;
    private String title;
    private Date date;
    private Person person;
    
    @Id
    @GeneratedValue
    public long getId() {
    
        return this.id;
    }
    
    public void setId(long id) {
    
        this.id = id;
    }
    
    public String getTitle() {
    
        return this.title;
    }
    
    @ManyToOne
    @JoinTable(
        name="person_event",
        joinColumns=@JoinColumn(name="e_id"),
        inverseJoinColumns=@JoinColumn(name="p_id"),
        uniqueConstraints=@UniqueConstraint(columnNames={"p_id"})
    )
    public Person getPerson() {
    
        return person;
    }
    
    public void setPerson(Person person) {
    
        this.person = person;
        if(person.getEvents()!=null){
            person.getEvents().add(this);
        }else{
            HashSet<Event> set = new HashSet<Event>();
            set.add(this);
            person.setEvents(set);
        }
    }

    public void setTitle(String title) {
    
        this.title = title;
    }
    
    public Date getDate() {
    
        return this.date;
    }
    
    public void setDate(Date date) {
    
        this.date = date;
    }
   
}

Person.java：

package com.chinaforwards.niagara.ems.jpa;

import java.io.Serializable;
import java.util.Date;
import java.util.Set;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;
import javax.persistence.Transient;

@Entity
@Table(name="person")
public class Person implements Serializable {

    private long id;
    private String name;
    private int age;
    private Date birthday;
    private int sex;
    private Set<Event> events;
    private static final long serialVersionUID = 1L;
    
    @OneToMany(cascade=CascadeType.ALL,mappedBy="person")
    public Set<Event> getEvents() {
    
        return this.events;
    }

    public void setEvents(Set<Event> events) {
    
        this.events = events;
    }

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    public long getId() {

        return this.id;
    }

    public void setId(long id) {

        this.id = id;
    }

    @Column(length=10)
    public String getName() {

        return this.name;
    }

    public void setName(String name) {

        this.name = name;
    }

    public int getAge() {

        return this.age;
    }

    public void setAge(int age) {

        this.age = age;
    }

    public Date getBirthday() {

        return this.birthday;
    }

    public void setBirthday(Date birthday) {

        this.birthday = birthday;
    }
    
    @Transient
    public int getSex() {
    
        return this.sex;
    }

    public void setSex(int sex) {
    
        this.sex = sex;
    }

}

配置大致就是这样，下面看下简单的dao层，利用spring自动的事务机制：
TestDao.java：

package com.chinaforwards.niagara.web.test;

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

@Transactional     
@Service("service") 
public class TestDao implements IDao{
    
    @PersistenceContext
    EntityManager em; 
    
    @Transactional(propagation = Propagation.REQUIRED)
    public void save(Object o){
        
        em.persist(o);
//        throw new RuntimeException("niub");
    }
    
    @Transactional(propagation = Propagation.REQUIRED)
    public Object get(Class c, Object k){
        
        return em.find(c, k);
    }
}

简单的使用方法：
HibernateTestServlet.java：

package com.chinaforwards.niagara.web.test;

import java.io.IOException;
import java.util.Date;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.chinaforwards.niagara.ems.jpa.Event;
import com.chinaforwards.niagara.ems.jpa.Person;

/**
 * Servlet implementation class HibernateTestServlet
 */
public class HibernateTestServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#HttpServlet()
     */
    public HibernateTestServlet() {
        super();
    }

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	    ServletContext servletContext = this.getServletContext();   
        WebApplicationContext ctx = WebApplicationContextUtils.getWebApplicationContext(servletContext);   
        IDao dao = (IDao)ctx.getBean("service");  
        Person p = new Person();
        p.setName("ggg");
        p.setBirthday(new Date(System.currentTimeMillis()));
        p.setAge(22);
        p.setSex(0);
        Event e = new Event();
        e.setDate(new Date(System.currentTimeMillis()));
        e.setTitle("cvv");
        e.setPerson(p);
        try {
            dao.save(p);
        } catch (Exception e1) {
            e1.printStackTrace();
        }
        
        Person p2 = (Person) dao.get(Person.class, p.getId());
        System.out.println(p2.getEvents() == null);//false
        
        Event e2 = (Event) dao.get(Event.class, e.getId());
        System.out.println(e2.getPerson() == null);//false
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doGet(request, response);
	}

}

接下来加入jsf的整合
faces-config.xml：

<?xml version="1.0" encoding="UTF-8"?>

<faces-config xmlns="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">

	<application>
		<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
	</application>

	<navigation-rule>
		<from-view-id>/index.xhtml</from-view-id>
		<navigation-case>
			<from-outcome>success</from-outcome>
			<to-view-id>/test.xhtml</to-view-id>
		</navigation-case>
		<navigation-case>
			<from-outcome>failure</from-outcome>
			<to-view-id>/index.xhtml</to-view-id>
		</navigation-case>
	</navigation-rule>

	<managed-bean>
		<managed-bean-name>user</managed-bean-name>
		<managed-bean-class>com.chinaforwards.niagara.web.test.User</managed-bean-class>
		<managed-bean-scope>session</managed-bean-scope>
		<managed-property>
			<property-name>dao</property-name>
			<value>#{service}</value>
		</managed-property>
	</managed-bean>
</faces-config>

web.xml中加入jsf的支持:

<servlet>
		<servlet-name>FacesServlet</servlet-name>
		<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
		<load-on-startup>0</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>FacesServlet</servlet-name>
		<url-pattern>*.xhtml</url-pattern>
	</servlet-mapping>

jsf的管理bean：

package com.chinaforwards.niagara.web.test;

import java.util.Date;

import com.chinaforwards.niagara.ems.jpa.Event;
import com.chinaforwards.niagara.ems.jpa.Person;

public class User {
    
    private String name;
    private IDao dao;
    public String login(){
        
        String ret = "";
        if("qygeng".equals(name)){
            Person p = new Person();
            p.setName("qygeng");
            p.setBirthday(new Date(System.currentTimeMillis()));
            p.setAge(22);
            p.setSex(0);
            Event e = new Event();
            e.setDate(new Date(System.currentTimeMillis()));
            e.setTitle("admin");
            e.setPerson(p);
            try {
                dao.save(p);
            } catch (Exception e1) {
                e1.printStackTrace();
            }
            ret = "success";
        }else{
            ret = "failure";
        }
        return ret;
    }
    
    public String getName() {
    
        return this.name;
    }
    
    public void setName(String name) {
    
        this.name = name;
    }
    
    public IDao getDao() {
    
        return this.dao;
    }
    public void setDao(IDao dao) {
    
        this.dao = dao;
    }
}

最后，就是页面的编写：

<?xml version="1.0" encoding="UTF-8" ?>
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
<body>
<f:view>
	<h:form>
		<h3>请输入您的名称</h3>
		名称: <h:inputText value="#{user.name}" />
		<h:commandButton value="送出" action="#{user.login}" />
	</h:form>
</f:view>
</body>
</html>
