MySql数据库的两种连接方式：

1com.mysql.jdbc.Driver

<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
String url ="jdbc:mysql://localhost/test?user=root&password=admin&useUnicode=true&characterEncoding=GB2312" ;
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement();
String query="select * from custom_id";
ResultSet rs=stmt.executeQuery(query);
while(rs.next())
{
        String s=rs.getString("name");//看准你的字段是不是字符型，不然就不能用getString
        out.print(s+"<br>");
}
%>
</body>
</html>

2 org.gjt.mm.mysql.Driver

<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url ="jdbc:mysql://localhost/test?user=root&password=admin&useUnicode=true&characterEncoding=GB2312" ;
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement();
String query="select * from custom_id";
ResultSet rs=stmt.executeQuery(query);
while(rs.next())
{
        String s=rs.getString("name");//看准你的字段是不是字符型，不然就不能用getString
        out.print(s+"<br>");
}
%>
</body>
</html>
