本文實(shí)例講述了JSP使用JDBC連接MYSQL數(shù)據(jù)庫的方法。分享給大家供大家參考，具體如下：
1. 可在 http://www.mysql.com/products/connector-j/index.html下載MySQL JDBC驅(qū)動(dòng)程序mysql-connector-java-*.jar,如我下載的是mysql-connector-java-5.1.18-bin.jar并加入到ClassPath下面，或加入到項(xiàng)目中。
2. 注冊(cè)JDBC驅(qū)動(dòng)程序
try { Class.forName("com.mysql.jdbc.Driver"); } catch(ClassNotFoundException e) { System.out.println("找不到驅(qū)動(dòng)程序"); } 3. 提供JDBC URL
jdbc:mysql://主機(jī)名:端口號(hào)/數(shù)據(jù)庫名?user=***&password=***&useUnicode=true&characterEncoding=UTF8
端口號(hào):MySQL的默認(rèn)值是3306
useUnicode,characterEncoding:如果要存取中文,則必須使用,表明是否使用Unicode,并指定編碼方式.
4. 從DriverManager取得Connection
可以直接將JDBC URL傳入DriverManager.getConnection()得到Connection對(duì)象,如:
try { String url = "jdbc:mysql://localhost:3306/GUESTBOOK?user=root&password=123456"; Connection conn = DriverManager.getConnection(url); if(!conn.isClosed()) System.out.println("數(shù)據(jù)庫連接成功!"); conn.close(); } catch(SQLException e) { .... } 也可以將userName和password傳入DriverManager.getConnection()得到Connection對(duì)象,如:
String url = "jdbc:mysql://localhost:3306/AddressBook"; String user = "ZhuJun"; String password = "123456"; Connection conn = DriverManager.getConnection(url, user, password);
一個(gè)完整的例子:
import java.sql.*;public class TestJDBC { public static void main(String[] args) throws Exception { Class.forName("com.mysql.jdbc.Driver"); String url = "jdbc:mysql://localhost:3306/2"; String user = "root"; String password = "19870714"; Connection conn = DriverManager.getConnection(url, user, password); if(!conn.isClosed()) { System.out.println("success"); } conn.close(); }} 希望本文所述對(duì)大家JSP程序設(shè)計(jì)有所幫助。
