Hibernate中Entity实体类的写法

记录下一个Entity类的写法，方便以后查阅：

package com.bupt.auth.entity;

import java.util.Date;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="token")
public class Token {
    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id", unique=true, nullable=false)
    private Long id;
    
    @Column(name="info")
    private String info;
    
    @Column(name="starttime")
    private Date starttime;
    
    @Column(name="endtime")
    private Date endtime;
    
    @ManyToOne(targetEntity=User.class)
    @JoinTable(name="userToken",
            joinColumns=@JoinColumn(name="token_id",referencedColumnName="id",unique=true),
            inverseJoinColumns=@JoinColumn(name="user_id",referencedColumnName="id"))
    private User user;
    
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }
    public String getInfo() {
        return info;
    }
    public void setInfo(String info) {
        this.info = info;
    }
    public Date getStarttime() {
        return starttime;
    }
    public void setStarttime(Date starttime) {
        this.starttime = starttime;
    }
    public Date getEndtime() {
        return endtime;
    }
    public void setEndtime(Date endtime) {
        this.endtime = endtime;
    }
    public User getUser() {
        return user;
    }
    public void setUser(User user) {
        this.user = user;
    }
    
}
