Web数据库学生实验报告JDBC部分

1、Web数据库技术学生实验报告 院 系： 信息科学与技术学院专 业： 信息管理与信息系统班 级： 信A1321/22任课教师： 张海 实验报告（一）院系：信息学院 课程名称：Web数据库技术 日期：班 级A1321姓 名黄伟峰专 业信息管理与信息系统学 号19实 验 室607实验名称Jdbc应用成 绩 评 定教 师 签 名实验目的1、 掌握数据库驱动的加载方式2、 掌握connection对象的使用方法3、 掌握statement对象使用方法4、 掌握事务的处理机制5、掌握数据持久层的设计实验内容connection对象、statement对象等应用1、 请设计一个工程类通过配置文件如下db.p

2、roperties来获得数据库连接的相关信息，并通过该配置文件获得数据库连接对象。url=jdbc:mysql://u5B66u751Fu5E93userName=adminpwd=adminpublic class connectionFactory public static Connection getConnection() throws SQLException请把getConnection（）方法补全。要求设计合理规范，必须有截图。答案：public class connectionFactory private static Properties pros =

3、new Properties() ;private static String driver ;private static String url ;private static String userName ;private static String pwd ;static InputStream is = connectionFactory.class.getClassLoader().getResourceAsStream("perties") ;try pros.load(is) ;driver = pros.getProperty("dr

4、iver") ;url = pros.getProperty("url") ;user = pros.getProperty("userName") ;pwd = pros.getProperty("pwd") ;Class.forName(driver) ; catch (Exception e) / TODO Auto-generated catch blocke.printStackTrace();public static Connection getConnection() throws SQLExceptionC

5、onnection conn = null ;try conn = DriverManager.getConnection(url, user, pwd) ;conn.setAutoCommit(false) ; catch (Exception e) / TODO Auto-generated catch blocke.printStackTrace();return conn ;2、 已知学生定义如下：public class student private int id; private String stuId; private String name; private String

6、domCard;/楼栋宿舍号“31-507”private String bedNo;/床铺号public student(String stuId, String name, String domCard, String bedNo) super();Id = stuId; = name;this.domCard = domCard;this.bedNo = bedNo;public String toString()return "id="+id+"学号="+stuId+”;姓名=”+name+”;宿舍号=”+domCard+”;床

7、铺号=”+bedNo;/相应get、set方法省略有一class studentDataspublic static ArrayList<student> students=new ArrayList<student>();staticstudent stu=new student("会计A001121","张三","31栋908",1); students.add(stu); stu=new student("会计A001166","李四","31栋908&q

8、uot;,2); students.add(stu); stu=new student("会计A001177","王五","31栋807",4); students.add(stu); 现要求 （1） 根据student类建立一个学生表用来保存student类的相关属性。（2） 通过jdbc，将studentDatas的students集合中的所有学生保持到学生表中； public class StuAdd /* * param args * throws SQLException */public static void main(

9、String args) throws SQLException studentDatas stus = new studentDatas() ;Connection conn = connectionFactory.getConnection() ;PreparedStatement prStatement = null ;try for(student stu:stus.students)/增加String sql="insert into lianxi(学号,姓名,宿舍号,床铺号) values(?,?,?,?)"prStatement = conn.prepareS

10、tatement(sql) ;prStatement.setString(1, stu.getStuId() ;prStatement.setString(2, stu.getName() ;prStatement.setString(3, stu.getDomCard() ;dNo() ;prStatement.executeUpdate(); conn mit() ; catch (Exception e) try conn.rollback() ; catch (SQLException e1) / TODO Auto-generated catch blocke1.printStack

11、Trace();/ TODO Auto-generated catch blocke.printStackTrace();finallyif (prStatement != null) try prStatement.cancel() ; catch (SQLException e) / TODO Auto-generated catch blocke.printStackTrace();if (conn != null) try conn.close() ; catch (SQLException e) / TODO Auto-generated catch blocke.printStac

12、kTrace();class studentDataspublic static ArrayList<student> students=new ArrayList<student>();static student stu=new student("会计A001121","张三","31栋908","1"); students.add(stu); stu=new student("会计A001166","李四","31栋908",

13、"2"); students.add(stu); stu=new student("会计A001177","王五","31栋807","4"); students.add(stu); （3） 通过jdbc，将学生表中所有的宿舍是” 31栋908”学生全部调整到“20栋371”宿舍；public class StuAlter /* * param args * throws SQLException */public static void main(String args) throws SQL

14、Exception / TODO Auto-generated method stubConnection conn = connectionFactory.getConnection() ;PreparedStatement prStatement = null ;try /修改String sql = "update lianxi set 宿舍号 =? where 宿舍号=?" ;prStatement = conn.prepareStatement(sql) ;prStatement.setString(1, "20栋371") ;prStatem

15、ent.setString(2, "31栋908") ;prStatement.executeUpdate() ;conn mit() ; catch (Exception e) try conn.rollback() ; catch (SQLException e1) / TODO Auto-generated catch blocke1.printStackTrace();/ TODO Auto-generated catch blocke.printStackTrace();finallyif (prStatement != null) try prStatement

16、.cancel() ; catch (SQLException e) / TODO Auto-generated catch blocke.printStackTrace();if (conn != null) try conn.close() ; catch (SQLException e) / TODO Auto-generated catch blocke.printStackTrace();（4）通过jdbc，删除"31栋807"床铺号是4的学生。public class StuDeletion /* * param args * throws SQLExcepti

17、on */public static void main(String args) throws SQLException / TODO Auto-generated method stubList<student> students=new ArrayList<student>();Connection conn = connectionFactory.getConnection() ;ResultSet rs = null ;PreparedStatement prStatement = null ;try /删除String sql = "delete

18、from lianxi where 宿舍号='31栋807' and 床铺号='4'" ;prStatement=conn.prepareStatement(sql);prStatement.executeUpdate();conn mit() ; catch (Exception e) try conn.rollback() ; catch (SQLException e1) / TODO Auto-generated catch blocke1.printStackTrace();/ TODO Auto-generated catch blocke

19、.printStackTrace();finallyif (prStatement != null) try prStatement.cancel() ; catch (SQLException e) / TODO Auto-generated catch blocke.printStackTrace();if (conn != null) try conn.close() ; catch (SQLException e) / TODO Auto-generated catch blocke.printStackTrace();3、 ResultSet对象操作请将上题中宿舍号最后一位是”8”的

20、学生信息全部显示出来。public class StuQuery /* * param args * throws SQLException */public static void main(String args) throws SQLException / TODO Auto-generated method stubList<student> students=new ArrayList<student>();Connection conn = connectionFactory.getConnection() ;ResultSet rs = null ;Pre

21、paredStatement prStatement = null ;student stu = null ;try String sql = "select lianxi.* from lianxi where 宿舍号 like '%8'" ;prStatement = conn.prepareStatement(sql) ;rs = prStatement.executeQuery(sql) ;while (rs.next() stu=new student(sql, sql, sql, sql);stu.setId(rs.getInt("id");stu.setStuId(rs.getString("学号");stu.setName(rs.getString("姓名");stu.setDomCard(rs.getString("宿舍号");stu.setBedNo(rs.getString("床铺号");students.add(stu);System.out
