数据库中的date转实体类中的java.util.Date

测试转换方法：

importjava.text.SimpleDateFormat;importjava.util.Date;publicclassStudent{privateint id;privateString sno;privateString sname;privatejava.util.Date birthday;publicintgetId(){return id;}publicvoidsetId(int id){this.id = id;}publicStringgetSno(){return sno;}publicvoidsetSno(String sno){this.sno = sno;}publicStringgetSname(){return sname;}publicvoidsetSname(String sname){this.sname = sname;}publicDategetBirthday(){return birthday;}publicvoidsetBirthday(Date birthday){this.birthday = birthday;}publicstaticvoidmain(String[] args){java.sql.Date d1=newjava.sql.Date(System.currentTimeMillis());java.util.Date d2 =newjava.util.Date(d1.getTime());Student stu =newStudent();
        stu.setBirthday(d2);SimpleDateFormat fmt =newSimpleDateFormat("yyyy-MM-dd");System.out.println(fmt.format(d2));}}
