13.2.3 创建持久化实体类

• 持久化对象之间的关联关系以成员变量的方式表现出来,当然这些成员变量同样需要setter和getter方法的支持。持久化类之间的关联关系通常对应数据库里的主、外键约束.
• 除此之外,持久化对象还有自己的普通类型的成员变量,这些成员变量通常对应数据库的字段。

下面是6个持久化类的源代码.

User.java

package org.fkit.hrm.domain;
import java.io.Serializable;
import java.util.Date;
public class User
    implements Serializable
{
    private static final long serialVersionUID = 1L;
    private Integer id;            // id
    private String username;    // 用户名
    private String loginname;    // 登录名
    private String password;    // 密码
    private Integer userstatus; // 状态
    private Date createDate;    // 建档日期
    // 无参数构造器
    public User()
    {
        super();
    }
    // setter和getter方法
    // 此处省略getter和setter方法,请自己补上
    @Override
    public String toString()
    {
        return "User [id=" + id + ", username=" + username + ", loginname=" + loginname
