---方法二使用java web 在Class文件中連接連接SQLsever 和 MySQL的驅(qū)動

public class connDAO { 
public Connection openconn() 
{Connection conn=null; 
try { 
//這是連接【MYSQL】的數(shù)據(jù)庫連接參數(shù)對象 
Class.forName("com.mysql.jdbc.Driver"); 
//【SQL server 鏈接】 
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");//加載數(shù)據(jù)庫驅(qū)動，注冊到驅(qū)動管理器 
//這是連接【MYSQL】的數(shù)據(jù)庫連接參數(shù)對象 【方式一】 
/* Class.forName("com.mysql.jdbc.Driver"); //加載Mysql驅(qū)動。 
String URL="jdbc:mysql://localhost:3306/db_database10"; 
String username="惜憶隱蝶"; 
String userpassword="123"; 
conn=DriverManager.getConnection(URL, username, userpassword);//建立連接 
*/ 
// 【方式二】 
// Class.forName("com.mysql.jdbc.Driver"); 
// conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/db_database10","惜憶隱蝶","123");//實行連接參數(shù) 庫名 用戶名 和密碼 
} catch (ClassNotFoundException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} 
/* String URL="jdbc:mysql://localhost:3306/db_database10"; 
String username="aa"; 
String userpassword="aa"; 
*/ 
try { 
//這是連接【MYSQL】的數(shù)據(jù)庫連接參數(shù)對象 
// conn=DriverManager.getConnection(URL, username, userpassword); 
//【SQL server 鏈接】 
conn=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databasename=db_database10", "惜憶隱蝶","qwe199509060"); 
} catch (SQLException e) { 
// TODO Auto-generated catch block 
e.printStackTrace(); 
} 
return conn; 
} 
}

注意：這里面要下載一個驅(qū)動包我的資源中有MySQL 和SQL server 的驅(qū)動包自己去下載！

-----------------------------------------------------給一個最終規(guī)范格式試題-------------------------------------------

代碼如下，不多做解析：

import java.sql.*; 
public class DBConnectionManager { 
//SQLServer 
private String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";//加載驅(qū)動程序 
private String url = "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=master";//設(shè)置數(shù)據(jù)庫連接串 
private String user = "sa";//數(shù)據(jù)庫登錄用戶名 
private String password = "root";//數(shù)據(jù)庫登錄密碼 
private static String message = "恭喜，數(shù)據(jù)庫連接正常！"; 
public void setDriverName(String newDriverName) { 
driverName = newDriverName; 
} 
public String getDriverName() { 
return driverName; 
} 
public void setUrl(String newUrl) { 
url = newUrl; 
} 
public String getUrl() { 
return url; 
} 
public void setUser(String newUser) { 
user = newUser; 
} 
public String getUser() { 
return user; 
} 
public void setPassword(String newPassword) { 
password = newPassword; 
} 
public String getPassword() { 
return password; 
} 
public Connection getConnection() { 
try { 
Class.forName(driverName); 
return DriverManager.getConnection(url, user, password); 
} catch (Exception e) { 
e.printStackTrace(); 
message = "數(shù)據(jù)庫連接失敗！"; 
return null; 
} 
} 
public static void main(String[] args) { 
try{ 
DBConnectionManager dcm = new DBConnectionManager(); 
Connection conn = dcm.getConnection(); 
System.out.println(message); 
}catch(Exception e){ 
e.printStackTrace(); 
} 
} 
} 
///第二種 
package net.jiaxiang.Dao; 
import java.sql.Connection; 
import java.sql.DriverManager; 
public class Conn { 
//定義提示 測試變量 
private static String message = "恭喜，數(shù)據(jù)庫連接正常！"; 
//連接方法 
public static Connection getConnection(){ 
try { 
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");//加載驅(qū)動 
return DriverManager.getConnection( "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=master", "惜憶隱碟", "qwe199509060");//實行連接參數(shù) 庫名 用戶名 和密碼 
} catch (Exception e) { 
message = "數(shù)據(jù)庫連接失??！"; 
e.printStackTrace();//打印異常 
return null; 
} 
} 
public static void main(String[] args) { 
getConnection();//調(diào)用連接 
System.out.println(message);//測試情況 
} 
}

以上所述是小編給大家介紹的使用java web 在jsp文件及Class中連接MySQL和SQLserver 的驅(qū)動方法，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復(fù)大家的。在此也非常感謝大家對腳本之家網(wǎng)站的支持！
