篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了JavaWeb课程设计：用户和商品管理系统相关的知识，希望对你有一定的参考价值。
设计要求
使用JavaWeb写一个管理系统，可以进行登录注册，对mysql数据库中的用户和商品信息进行管理。
使用工具
IDEA、MySQL Workbench、LayUI框架
需要源码的可以从下面链接获取
注册界面
一、表单
html的form表单。onblur()是输入框失去焦点时执行的函数。
<form id="Form" method="POST" action="register">
<div class="form-item">
<div class="form-title">用户名</div>
<input type="text" name="Name" id="name-input" onblur="checkName()">
</div>
<div id="name-errMsg"></div> <!--用于显示错误信息 -->
<div class="form-item">
<div class="form-title">密码</div>
<input type="password" name="Pwd" id="pwd-input1" onblur="checkPwd1()">
</div>
<div id="pwd-errMsg1"></div>
<div class="form-item">
<div class="form-title">重复密码</div>
<input type="password" name="Pwd2" id="pwd-input2" onblur="checkPwd2()">
</div>
<div id="pwd-errMsg2"></div>
<div class="form-item">
<div class="form-title">昵称</div>
<input type="text" name="NickName" id="nickName-input" onblur="checkEmail()">
</div>
<div id="nickName-div"></div>
<div class="form-item">
<div class="form-title">电话号码</div>
<input type="number" name="Tel" id="tel-input" onblur="checkTel()" >
</div>
<div id="tel-errMsg"></div>
<div class="form-item">
<div class="form-title">邮箱</div>
<input type="text" name="Email" id="email-input" onblur="checkEmail()">
</div>
<div id="email-errMsg"></div>
<div class="form-item">
<div class="form-title">住址</div>
<input type="text" name="Address" id="address-input" onblur="checkEmail()">
</div>
<div id="address-div"></div>
<div id="submit-div">
<div id="submit-left">
</div>
<div id="submit-mid">
<button type="submit" id="Submit">注册</button>
</div>
<div id="submit-right">
<a href="LoginPage.jsp" id="login">已有账号，前往登录</a>
</div>
</div>
</form>
二、注册格式检查
注册格式检查需要检查：
- 用户名：不能包含特殊字符
- 密码：不能包含特殊字符
- 重复密码一致性检查
- 电话号码：十一位数字
- 邮箱：格式检查
