1. 如何用eclipse寫登錄注冊頁面的代碼
java寫的用戶登錄實例，實際頁面展示使用的jsp，那麼下面是jsp的登錄頁面代碼：
1、login.jsp代碼
<%
string name = request.getparameter("username");
string pwd = request.getparameter("password");
//out.println(name+pwd);
string sql ="select * from info where username='"+name+"' and password='"+pwd+"'";
//out.println(sql);
statement stm= null;
resultset rs =null;
try
{
stm = conn.createstatement();
rs = stm.executequery(sql);
if(rs.next())
{
session.setattribute("username",name);
response.sendredirect("index.html");
}
else
{
response.sendredirect("index1.html");
}
}
catch(sqlexception e)
{
e.printstacktrace();
}
%>
<!--登錄的表單-->
<form name="form1" method="post" action="login.jsp">
<p>
<label for="username"></label> 用戶名
<input type="text" name="username" id="username">
</p>
<p>
<label for="passwrod"></label> 密碼
<input type="text" name="passwrod" id="passwrod">
</p>
<p>
<input type="submit" name="button" id="button" value="提交">
</p>
</form>
2、用戶信息表，存放用戶名和密碼：
user_info 表
create table if not exists `test` (
`id` int(8) not null auto_increment,
`username` char(150) default null,
`password` varchar(32),
`times` int(4) not null,
primary key (`id`)
) engine=myisam default charset=utf8 auto_increment=1 ;
2. java寫的用戶登陸實例，用eclipse開發的具體步奏和代碼

<p>
<label for="passwrod"></label> 密碼
<input type="text" name="passwrod" id="passwrod">

<p>
<input type="submit" name="button" id="button" value="提交">
</p>
