Spring MVC的Controller接受请求方式以及编写请求处理方法

创建register.jsp代码：

复制代码
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<form action="${pageContext.request.contextPath }/user/register" method="post" name="registForm">    <table     border=1     bgcolor="lightblue"     align="center">        <tr>            <td>姓名：</td>            <td>                <input class="textSize" type="text" name="uname" value="${user.uname }"/>            </td>        </tr>                <tr>            <td>密码：</td>            <td><input class="textSize" type="password" maxlength="20" name="upass"/></td>        </tr>                <tr>            <td>确认密码：</td>            <td><input class="textSize" type="password" maxlength="20" name="reupass"/></td>        </tr>                <tr>            <td colspan="2" align="center"><input type="button" value="注册"  ="allIsNull()"/></td>        </tr>    </table></form>
