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));
}

}
