1. 可在 http://www.mysql.com/products/connector-j/index.html下載MySQL JDBC驅(qū)動程序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，或加入到項目中。

2. 注冊JDBC驅(qū)動程序

try { 
   Class.forName("com.mysql.jdbc.Driver"); 
} 
catch(ClassNotFoundException e) { 
   System.out.println("找不到驅(qū)動程序"); 
}

3. 提供JDBC URL

jdbc:mysql://主機名:端口號/數(shù)據(jù)庫名?user=***&password=***&useUnicode=true&characterEncoding=UTF8

端口號:MySQL的默認值是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對象,如:

String url = "jdbc:mysql://localhost:3306/AddressBook"; 
String user = "ZhuJun"; 
String password = "123456"; 
Connection conn = DriverManager.getConnection(url, user, password);

一個完整的例子:

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();
 }
}

希望本文所述對大家JSP程序設(shè)計有所幫助。
