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" onclick="allIsNull()"/></td>
        </tr>
    </table>
</form>
