以MySQL为示例说明在JSP中操作数据库：

1、添加相应数据库的驱动程序，例如MySQL就是mysql-connector-java-5.1.25-bin.jar

2、建立MySQLTest.jsp页面进行编辑，输入以下代码进行测试

<%@page contentType="text/html; charset=gb2312"%>
<%@page language="java"%>
<%@page import="com.mysql.jbdc.*"%>
<%@page import="java.sql.*"%>

<%
String driverName="com.mysql.jdbc.Driver";
String userName="root";
String userPwd="123456";
String dbName="test";
String tableName="goods";

String url="jdbc:mysql://localhost/"+dbName+"?user="+userName+"&password="+userPwd;
Class.forName("com.mysql.jdbc.Driver").newInstance();
java.sql.Connection conn=DriverManager.getConnection(url);
out.print("数据库连接成功！");

out.print("<br>");

java.sql.Statement statement=conn.createStatement();
String sql="SELECT * from "+tableName;
java.sql.ResultSet rs=statement.executeQuery(sql);

out.print("商品编码");
out.print("|");
out.print("商品名称");
out.print("|");
out.print("价格（元）");
out.print("<br>");
while(rs.next())
{
    out.print(rs.getString(1)+"");
    out.print("|");
    out.print(rs.getString(2)+"");
    out.print("|");
    out.print(rs.getString(3)+"");
    out.print("<br>");
}

rs.close();
statement.close();
conn.close();
