数据库中的date转实体类中的java.util.Date

测试转换方法：

import java.text.SimpleDateFormat;
import java.util.Date;

public class Student {
    private int id;
    private String sno;
    private  String sname;
    private java.util.Date birthday;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getSno() {
        return sno;
    }

    public void setSno(String sno) {
        this.sno = sno;
    }

    public String getSname() {
        return sname;
    }

    public void setSname(String sname) {
        this.sname = sname;
    }

    public Date getBirthday() {
        return birthday;
    }

    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }

    public static void main(String[] args) {
        java.sql.Date d1=new java.sql.Date(System.currentTimeMillis());
        java.util.Date d2 = new java.util.Date(d1.getTime());
        Student stu = new Student();
        stu.setBirthday(d2);
        SimpleDateFormat fmt = new SimpleDateFormat("yyyy-MM-dd");
        System.out.println(fmt.format(d2));
    }
}
