和上一篇对应，只是改了一下name的属性罢了，

package org.crazyit.app.domain;import java.util.*;import javax.persistence.*;import org.hibernate.annotations.Parent;/** * Description: * <br/>网站: <a href="http://www.crazyit.org">疯狂Java联盟</a> * <br/>Copyright (C), 2001-2016, Yeeku.H.Lee * <br/>This program is protected by copyright laws. * <br/>Program Name: * <br/>Date: * @author  Yeeku.H.Lee kongyeeku@163.com * @version  1.0 */@Embeddablepublic class Name{// 定义first成员变量@Column(name="person_firstname")private String first;// 定义last成员变量@Column(name="person_lastname")private String last;// 引用拥有该Name的Person对象@Parentprivate Person owner;// 集合属性，保留该对象关联的考试成绩@ElementCollection(targetClass=Integer.class)@CollectionTable(name="power_inf",joinColumns=@JoinColumn(name="person_name_id" , nullable=false))@MapKeyColumn(name="name_aspect")@Column(name="name_power" , nullable=false)@MapKeyClass(String.class)private Map<String , Integer> power= new HashMap<>();// 无参数的构造器public Name(){}// 初始化全部成员变量的构造器public Name(String first , String last){this.first = first;this.last = last;}// first的setter和getter方法public void setFirst(String first){this.first = first;}public String getFirst(){return this.first;}// last的setter和getter方法public void setLast(String last){this.last = last;}public String getLast(){return this.last;}// owner的setter和getter方法public void setOwner(Person owner){this.owner = owner;}public Person getOwner(){return this.owner;}// power的setter和getter方法public void setPower(Map<String ,Integer> power){this.power = power;}public Map<String ,Integer> getPower(){return this.power;}}

其实和在持久化类中注解属性集合在数据库中是一样啦
