Web數(shù)據(jù)庫學生實驗報告JDBC部分

1、Web數(shù)據(jù)庫技術學生實驗報告 院 系： 信息科學與技術學院專 業(yè)： 信息管理與信息系統(tǒng)班 級： 信A1321/22任課教師： 張海 實驗報告（一）院系：信息學院 課程名稱：Web數(shù)據(jù)庫技術 日期：班 級A1321姓 名黃偉峰專 業(yè)信息管理與信息系統(tǒng)學 號19實 驗 室607實驗名稱Jdbc應用成 績 評 定教 師 簽 名實驗目的1、 掌握數(shù)據(jù)庫驅(qū)動的加載方式2、 掌握connection對象的使用方法3、 掌握statement對象使用方法4、 掌握事務的處理機制5、掌握數(shù)據(jù)持久層的設計實驗內(nèi)容connection對象、statement對象等應用1、 請設計一個工程類通過配置文件如下db.p

2、roperties來獲得數(shù)據(jù)庫連接的相關信息，并通過該配置文件獲得數(shù)據(jù)庫連接對象。url=jdbc:mysql://u5B66u751Fu5E93userName=adminpwd=adminpublic class connectionFactory public static Connection getConnection() throws SQLException請把getConnection（）方法補全。要求設計合理規(guī)范，必須有截圖。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、 已知學生定義如下：public class student private int id; private String stuId; private String name; private String

6、domCard;/樓棟宿舍號“31-507”private String bedNo;/床鋪號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+"學號="+stuId+”;姓名=”+name+”;宿舍號=”+domCard+”;床

7、鋪號=”+bedNo;/相應get、set方法省略有一class studentDataspublic static ArrayList<student> students=new ArrayList<student>();staticstudent stu=new student("會計A001121","張三","31棟908",1); students.add(stu); stu=new student("會計A001166","李四","31棟908&q

8、uot;,2); students.add(stu); stu=new student("會計A001177","王五","31棟807",4); students.add(stu); 現(xiàn)要求 （1） 根據(jù)student類建立一個學生表用來保存student類的相關屬性。（2） 通過jdbc，將studentDatas的students集合中的所有學生保持到學生表中； 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(學號,姓名,宿舍號,床鋪號) 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("會計A001121","張三","31棟908","1"); students.add(stu); stu=new student("會計A001166","李四","31棟908",

13、"2"); students.add(stu); stu=new student("會計A001177","王五","31棟807","4"); students.add(stu); （3） 通過jdbc，將學生表中所有的宿舍是” 31棟908”學生全部調(diào)整到“20棟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 宿舍號 =? where 宿舍號=?" ;prStatement = conn.prepareStatement(sql) ;prStatement.setString(1, "20棟371") ;prStatem

15、ent.setString(2, "31棟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）通過jdbc，刪除"31棟807"床鋪號是4的學生。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 /刪除String sql = "delete

18、from lianxi where 宿舍號='31棟807' and 床鋪號='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對象操作請將上題中宿舍號最后一位是”8”的

20、學生信息全部顯示出來。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 宿舍號 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("學號");stu.setName(rs.getString("姓名");stu.setDomCard(rs.getString("宿舍號");stu.setBedNo(rs.getString("床鋪號");students.add(stu);System.out
