  • 单纯的简单的ibatis

    架包:sqljdbc4.jar+ibatis-2.3.4.jar+junit4.jar

    数据库简要说明:

    数据库名:ibatisTest 用户名:sa 密码:yyy

    字段有:id(int),sname(varchar),birth(Date),score(float)

    利用的是sqlserver2008

    1.同一个包下:com.com

    2.IbatisTest.java

     1 package com.com;
     2 
     3 import java.sql.Date;
     4 import java.util.List;
     5 
     6 import org.junit.Test;
     7 
     8 public class IbatisTest {
     9     @Test
    10     public void IbatisTest() throws Exception
    11     {
    12         IStudentDAO iStudentDAO=new IStudentDAOImpl();
    13         //1.查询所有
    14         /*System.out.println("测试查询所有:");
    15         List<Student> students=iStudentDAO.selectAllStudent();
    16         for(Student student:students)
    17             System.out.println(student.toString());*/
    18         //2.插入
    19         /*Student student=new Student();
    20         student.setId(311);
    21         student.setSname("依依");
    22         student.setBirth(Date.valueOf("2013-5-5"));
    23         student.setScore(100);
    24         iStudentDAO.addStudent(student);*/
    25         //3.修改
    26         /*Student student=new Student();
    27         student.setId(161);
    28         student.setSname("依依");
    29         student.setBirth(Date.valueOf("2013-12-12"));
    30         iStudentDAO.updateStudent(student);*/
    31         //4.删除
    32         //iStudentDAO.deleteStudent(31);
    33         //5.依名字查询  =查询:sname=#sname# 模糊:'%$sname$%'
    34         /*List<Student> students=iStudentDAO.selectStudentByName("依依");
    35         for(Student student:students)
    36             System.out.println(student.toString());*/
    37         //6.依Id查询,这个中唯一的。
    38         System.out.println(iStudentDAO.selectStudentById(161));
    39     }
    40 
    41 }
