关于jdbc的数据库驱动类DriverManager.getConnection()参数

1、Oracle8/8i/9i数据库(thin模式) 
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance(); 
String url="jdbc:oracle:thin:@localhost:1521:orcl"; 
//orcl为数据库的SID 
String user="test"; 
String password="test"; 
Connection conn=DriverManager.getConnection(url,user,password); 
2、DB2数据库 
Class.forName("com.ibm.db2.jdbc.app.DB2Driver").newInstance(); 
String url="jdbc:db2://localhost:5000/sample"; 
//sample为你的数据库名 
String user="admin"; 
String password=""; 
Connection conn=DriverManager.getConnection(url,user,password); 
3、SqlServer7.0/2000数据库(三个jar包:msbase.jar,mssqlserver.jar,msutil.jar)
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance(); 
Stringurl="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb"; 
//mydb为数据库 
String user="sa"; 
String password=""; 
Connection conn=DriverManager.getConnection(url,user,password);

注意:一个jar包(sqljdbc4.jar)的时候,应该是这样的,除掉“microsoft”

Class.forName("com.jdbc.sqlserver.SQLServerDriver").newInstance(); 
Stringurl="jdbc:sqlserver://localhost:1433;DatabaseName=mydb"; 


4、Sybase数据库 
Class.forName("com.sybase.jdbc.SybDriver").newInstance(); 
String url =" jdbc:sybase:Tds:localhost:5007/myDB"; 
//myDB为你的数据库名 
Properties sysProps = System.getProperties(); 
SysProps.put("user","userid"); 
SysProps.put("password","user_password"); 
Connection conn= DriverManager.getConnection(url,SysProps); 
5、Informix数据库 
Class.forName("com.informix.jdbc.IfxDriver").newInstance(); 
String url = 
"jdbc:informix-sqli://123.45.67.89:1533/myDB:INFORMIXSERVER=myserver; 
user=testuser;password=testpassword"; 
//myDB为数据库名 
Connection conn= DriverManager.getConnection(url); 
6、MySQL数据库 
Class.forName("org.gjt.mm.mysql.Driver").newInstance(); 
String url="jdbc:mysql://localhost/myDB?user=soft&password=soft1234&useUnicod 
e=true&characterEncoding=8859_1" 
//myDB为数据库名 
Connection conn= DriverManager.getConnection(url); 
7、PostgreSQL数据库 
Class.forName("org.postgresql.Driver").newInstance(); 
String url ="jdbc:postgresql://localhost/myDB" 
//myDB为数据库名 
String user="myuser"; 
String password="mypassword"; 
Connection conn=DriverManager.getConnection(url,user,password);



<span style="font-size:14px;">import java.sql.*;

public class UrlDemo {
	public static final String url = "jdbc:mysql://localhost/test_db";  
    public static final String name = "com.mysql.jdbc.Driver";  
    public static final String user = "root";  
    public static final String password = "123456";  
    
	Connection con=null;
	public Connection getConnection(){
		try {
			Class.forName(name);
			System.out.println("数据库加载成功");
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		try {
			con=DriverManager.getConnection(url,user,password);
			System.out.println("数据库链接成功");
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}		
		return con;
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		UrlDemo u=new UrlDemo();	
		u.getConnection();
	}
}
