本来应该是13号交的，Edge浏览器抽风了提交不上

今天做的事：

编写了测试类

package DAO;

import java.util.Iterator;

import java.util.List;

/**

 * Created by wei on 2017/4/13.

 */

public class Test {

public static void main(String[] args){

 StudentDAO sd =new StudentDAOImp();

 sd.addStudent(new Student(("aa",(long)1,(long)20170413,(long)20170413,"java")));

 sd.deleteStudent(1);

 sd.updateStudent(new Student(("bb",(long)2,(long)20170414,(long)20170414,"java")));

//查询所有学生

        List<Student> students= sd.getAllStudents();

 Iterator<Student> iterator = students.iterator();

while (iterator.hasNext()){

 Student stu = iterator.next();

 System.out.println(stu.getId()+stu.getName());

 }

//根据编号

        Student stu = sd.getStudentById(1);

 System.out.println(stu.getId()+stu.getName());

//模糊查找

        List<Student> students1 = sd.getStudentsByCondition("a","java");

 Iterator<Student> iterator1 = students1.iterator();

while (iterator1.hasNext()){

 Student stu1 = iterator1.next();

 System.out.println(stu.getId()+stu.getName());

 }

 }

}

收获：DBUtil是要自己编写的

明天要做的事：编写数据库工具类DBUtil
