培根好吃
1.手机号校验
利用
手机号校验
public class ValidatorUtil {
private static final Pattern mobile_pattern=Pattern.compile("1\\d{10}");
public static boolean isMobile(String src) {
if(StringUtils.isEmpty(src)) {
return false;
}
Matcher m=mobile_pattern.matcher(src);
return m.matches();
}
public static void main(String[] args) {
System.out.println(isMobile("15757855000"));
System.out.println(isMobile("157578550sfsg"));
}
}
2.在templates里面建login.html页面
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>登录</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<!-- jquery -->
<script type="text/javascript" th:src="@{/js/jquery.min.js}"></script>
<!-- bootstrap -->
<link rel="stylesheet" type="text/css" th:href="@{/bootstrap/css/bootstrap.min.css}" />
<script type="text/javascript" th:src="@{/bootstrap/js/bootstrap.min.js}"></script>
<!-- jquery-validator -->
<script type="text/javascript" th:src="@{/jquery-validation/jquery.validate.min.js}"></script>
<script type="text/javascript" th:src="@{/jquery-validation/localization/messages_zh.min.js}"></script>
<!-- layer 弹框-->
<script type="text/javascript" th:src="@{/layer/layer.js}"></script>
<!-- md5.js -->
<script type="text/javascript" th:src="@{/js/md5.min.js}"></script>
<!-- common.js 展示loading框， 固定salt-->
<script type="text/javascript" th:src="@{/js/common.js}"></script>
</head>
<body>
<form name="loginForm" id="loginForm" method="post" style="width:50%; margin:0 auto">
<h2 style="text-align:center; margin-bottom: 20px">用户登录</h2>
<div class="form-group">
<div class="row">
<label class="form-label col-md-4">请输入手机号码</label>
<div class="col-md-5">
<input id="mobile" name = "mobile" class="form-control" type="text" placeholder="手机号码" required="true" minlength="11" maxlength="11" />
</div>
<div class="col-md-1">
</div>
</div>
</div>
<div class="form-group">
<div class="row">
<label class="form-label col-md-4">请输入密码</label>
<div class="col-md-5">
<input id="password" name="password" class="form-control" type="password" placeholder="密码" required="true" minlength="6" maxlength="16" />
</div>
</div>
</div>
<div class="row">
<div class="col-md-5">
<button class="btn btn-primary btn-block" type="reset" onclick="reset()">重置</button>
</div>
<div class="col-md-5">
<button class="btn btn-primary btn-block" type="submit" onclick="login()">登录</button>
</div>
</div>
</form>
</body>
<script>
function login(){
$("#loginForm").validate({
submitHandler:function(form){
doLogin();
}
});
}
function doLogin(){
g_showLoading();
var pass=$("#password").val();
var salt_fixed=g_passsword_salt;
var str=""+salt_fixed.charAt(0)+salt_fixed.charAt(2)+pass+salt_fixed.charAt(5)+salt_fixed.charAt(4);
var password=md5(str);
$ajax({
url:"/login/do_login",
type:"POST",
data:{
mobile:$("#mobile").val(),
password:password
},
success:function(data){
layer.closeAll();
if(data.code == 0){
layer.msg("成功");
window.location.href="/goods/to_list";
}else{
layer.msg(data.msg);
}
console.log(data);
},
error:function(){
}
});
}
</script>
</html>
3.将数据库的秒杀对象引入，作对比
MiaoshaUser
package com.ryan.miaosha.domain;

}

}
public Date getRegisterDate() {
return registerDate;
}

//请求成功 为什么传入loginVo 因为要接收网页表单传来的参数 将手机号和密码传入一个对象中
@RequestMapping("/do_login")
@ResponseBody

CodeMsg

/*
