載最新的mysql驅動程序(Mysql JDBC Driver )
解壓後，把裏面的mysql-connector-java-******-bin.jar文件複製到你的tomcat/common/lib下，重啓Tomcat，jsp連接mysql的環境就完成。
接下來，jsp提取數據庫數據的測試程序：
<%@ 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/db_name?user=yourusername&password=yourpassword&useUnicode=true&characterEncoding=GB2312" ;
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement();
String query="select field_name from table_name order by id";
ResultSet rs=stmt.executeQuery(query);
while(rs.next())
{
String s=rs.getString("field_name");//看準你的字段，不然就不能用getString
<%@ page import="java.sql.*"%>
<html>
<body>
<%
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
String url ="jdbc:mysql://localhost/db_name?user=yourusername&password=yourpassword&useUnicode=true&characterEncoding=GB2312" ;
Connection conn= DriverManager.getConnection(url);
Statement stmt=conn.createStatement();
String query="select field_name from table_name order by id";
ResultSet rs=stmt.executeQuery(query);
while(rs.next())
{
String s=rs.getString("field_name");//看準你的字段，不然就不能用getString
out.print(s+"<br>");
}
%>
</body>
</html>
}
%>
</body>
</html>
裏面的yourusername和yourpassword改成你的mysql的用戶名和密碼，其餘的db_name、field_name和table_name也照樣改成相應的名字即可
