1.   conn.jsp

<%
//驱动程序名
String   driverName= "com.mysql.jdbc.Driver ";
//数据库用户名
String   userName= "root ";
//密码
String   userPasswd= "123 ";
//数据库名
String   dbName= "myNote ";

//联结字符串
String   url= "jdbc:mysql://localhost/ "+dbName+ "?user= "+userName+ "&password= "+userPasswd;
Class.forName( "com.mysql.jdbc.Driver ").newInstance();
Connection   connection=DriverManager.getConnection(url);
Statement   statement   =   connection.createStatement();

//获得数据结果集合
//ResultSetMetaData   rmeta   =   rs.getMetaData();

//确定数据集的列数,亦字段数
//int   numColumns=rmeta.getColumnCount();
%>

2   add_data.jsp
<%@   page   contentType= "text/html;   charset=gb2312 "   %>
<%@   page   language= "java "   %>
<%@   page   import= "com.mysql.jdbc.Driver "   %>
<%@   page   import= "java.sql.* "   %>
<%@   include   file= "conn.jsp "%>
<html>
<head>
</head>
<body>
<%
//定义接受变量的参数
String   user_name;
String   user_email;
String   user_qq;
String   user_mob_no;
String   user_tel;
String   user_add;

//获取参数
                user_name   =   request.getParameter( "User_name ");
user_email   =   request.getParameter( "user_email ");
user_qq   =   request.getParameter( "user_qq ");
user_mob_no   =   request.getParameter( "user_mob_no ");
user_tel   =   request.getParameter( "user_tel ");
user_add   =   request.getParameter( "user_add ");

//test
out.print( "user   nam:   "   +   user_name   +   " <br> ");
out.print( "user   email:   "   +   user_email   +   " <br> ");
out.print( "user   qq:   "   +   user_qq   +   " <br> ");
out.print( "user   mobile:   "   +   user_mob_no   +   " <br> ");
out.print( "user   tel:   "   +   user_tel   +   " <br> ");

out.print( "user   add:   "   +   user_add   +   " <br> ");

//sql语句
String   sql= "INSERT   INTO   phone_book(name,email,qq,mobile_no,telephone,address)   VALUES( ' "   +   user_name   +   " ', ' "   +   user_email   +   " ', ' "   +   user_qq   + " ', ' "   +   user_mob_no   +   " ', ' "   +   user_tel   +   " ', ' "   +   user_add   +   " ') ";
out.print( "sql "   +   sql);

statement.executeQuery(sql);

statement.close();  
connection.close();  
%>
</body>
</html>
