首先新建一個(gè)典型web應(yīng)用程序
然后建一個(gè)com.storm包，在包下寫一個(gè)UserBean的類，添加private的屬性之后只要點(diǎn)擊菜單重構(gòu)－封裝字段就可以添加set和get方法
package ?com.storm;
 public ? class ?UserBean? {
???? private ?String?name;
???? private ? int ?sex;
???? private ?String?education;
???? private ?String?email;
???? public ?String?getName()? {
???????? return ?name;
????}

???? public ? void ?setName(String?name)? {
???????? this .name? = ?name;
????}

???? public ? int ?getSex()? {
???????? return ?sex;
????}

???? public ? void ?setSex( int ?sex)? {
???????? this .sex? = ?sex;
????}

???? public ?String?getEducation()? {
???????? return ?education;
????}

???? public ? void ?setEducation(String?education)? {
???????? this .education? = ?education;
????}

???? public ?String?getEmail()? {
???????? return ?email;
????}

???? public ? void ?setEmail(String?email)? {
???????? this .email? = ?email;
????}
}
然后再寫一個(gè)注冊(cè)頁面index.jsp
<% @page?contentType = " text/html;?charset=GB2312 " ? %>
< html >
???? < head >
???????? < meta?http - equiv = " Content-Type " ?content = " text/html;?charset=UTF-8 " >
???????? < title > JSP?Page </ title >
???? </ head >
???? < body >
???????? < form?name = " form " ?action = " reg.jsp " ?method = " POST " >
???????????? < table?border = " 1 " >
???????????????? < thead >
???????????????????? < tr >
???????????????????????? < td > 用戶名 </ td >
???????????????????????? < td >< input?type = " text " ?name = " name " ?value = "" ?width = " 6 " ? /></ td >
???????????????????? </ tr >
???????????????? </ thead >
???????????????? < tbody >
???????????????????? < tr >
???????????????????????? < td > 性別 </ td >
???????????????????????? < td > ?
???????????????????????????? < input?type = " radio " ?name = " sex " ?value = " 0 " ? /> 男
???????????????????????????? < input?type = " radio " ?name = " sex " ?value = " 1 " ? /> 女
???????????????????????? </ td >
???????????????????? </ tr >
???????????????????? < tr >
???????????????????????? < td > 學(xué)歷 </ td >
???????????????????????? < td >< select?name = " education " >
???????????????????????????? < option?value = " 高中 " ?selected > 高中 </ option >
???????????????????????????? < option?value = " 大學(xué) " > 大學(xué) </ option >
???????????????????????????? < option?value = " 碩士 " > 碩士 </ option >
???????????????????????????? < option?value = " 博士 " > 博士 </ option >
???????????????????????? </ select ></ td >
???????????????????? </ tr >
???????????????????? < tr >
???????????????????????? < td > EMAIL </ td >
???????????????????????? < td >< input?type = " text " ?name = " mail " ?value = "" ?width = " 10 " ? /></ td >
???????????????????? </ tr >
???????????????????? < tr >
???????????????????????? < td ></ td >
???????????????????????? < td ></ td >
???????????????????? </ tr >
???????????????????? < tr >
???????????????????????? < td >< input?type = " submit " ?value = " 提交 " ?name = " submit " ? /></ td >
???????????????????????? < td >< input?type = " reset " ?value = " 重置 " ?name = " reset " ? /></ td >
???????????????????? </ tr >
???????????????? </ tbody >
???????????? </ table > ?????
???????? </ form >
???? </ body >
</ html >

form會(huì)交給reg.jsp處理，reg.jsp負(fù)責(zé)實(shí)例化一個(gè)javabean,并儲(chǔ)存數(shù)據(jù)

<% @page?contentType = " text/html;?charset=GB2312 " ? %>
< html >
???? < head >
???????? < meta?http - equiv = " Content-Type " ?content = " text/html;?charset=UTF-8 " >
???????? < title > JSP?Page </ title >
???? </ head >
???? < body >
???????? <%
????????????request.setCharacterEncoding( " GB2312 " );
???????? %>
???????? < jsp:useBean?id = " user " ?scope = " session " ? class = " com.storm.UserBean " >
???????????? < jsp:setProperty?name = " user " ?property = " * " ? />
???????????? < jsp:setProperty?name = " user " ?property = " email " ?param = " mail " ? />
???????? </ jsp:useBean >
???? </ body >
</ html >

鏈接到get.jsp用于取出javabean的數(shù)據(jù)并顯示

<%@page?contentType="text/html;?charset=GB2312"?%>
<html>
????<head>
????????<meta?http-equiv="Content-Type"?content="text/html;?charset=UTF-8">
????????<title>JSP?Page</title>
????</head>
????<body>
<jsp:useBean?id="user"?scope="session"?class="com.storm.UserBean"?/>
????????<jsp:getProperty?name="user"?property="name"?/><br>
????????你的性別：<%?int?sex=user.getSex();
????????????if(0==sex)
????????????????out.println("男");
????????????else?if(1==sex)
????????????????out.println("女");
????????%>
????????<br>
????????你的學(xué)歷:<jsp:getProperty?name="user"?property="education"?/><br>
????????你的email:<jsp:getProperty?name="user"?property="email"?/><br>
????</body>
</html>


需要注意的是同一個(gè)javabean實(shí)例在打開瀏覽器之后創(chuàng)建并儲(chǔ)存數(shù)據(jù)直到關(guān)閉也無法通過后退再到Index.jsp－reg.jsp改變其中的數(shù)據(jù)
而且要支持中文必須在每個(gè)文件頭加上 <%@page?contentType="text/html;?charset=GB2312"?%>
