（三）Java高并发秒杀系统API之Web层开发
既然是Web层的会肯定要先引入SpringMvc了
- 修改
web.xml,引入SpringMvc的DispatcherServlet：
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
version="3.0"
metadata-complete="true">
<!--用maven创建的web-app需要修改servlet的版本为3.0-->
<servlet>
<servlet-name>seckill-dispatchServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--配置springmvc的配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</init-param>
<load-on-startup>
1
</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>seckill-dispatchServlet</servlet-name>
<!--直接拦截所有请求,不再采用spring2.0的/*或者*.do方式-->
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>在这里的话如果你不配置这一段代码的：
<!--配置springmvc的配置文件-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</init-param>SpringMvc默认就会默认去WEB-INF下查找默认规范的配置文件,像我这里配置的servlet-name是seckill-dispatchServlet的话,则默认会寻找WEB-INF一个名为seckill-dispatchServlet-Servlet.xml的配置文件
接下来编写Controller SeckillController
首先在com.suny下建立包为Controller的包,然后在里面新建一个类SeckillController：
package com.suny.controller;
/**
* Created by 孙
*/
@Controller
@RequestMapping("/seckill")
public class SeckillController {
private final SeckillService seckillService;
@Autowired
public SeckillController(SeckillService seckillService) {
this.seckillService = seckillService;
}
/**
* 进入秒杀列表.
*
* @param model 模型数据,里面放置有秒杀商品的信息
* @return 秒杀列表详情页面
*/
@RequestMapping(value = {"/list","","index"}, method = RequestMethod.GET)
public String list(Model model) {
List<Seckill> seckillList = seckillService.getSeckillList();
model.addAttribute("list", seckillList);
return "list";
}
@RequestMapping(value = "/{seckillId}/detail", method = RequestMethod.GET)
public String detail(@PathVariable("seckillId") Long seckillId, Model model) {
if (seckillId == null) {
return "redirect:/seckill/list";
}
Seckill seckill = seckillService.getById(seckillId);
if (seckill == null) {
return "forward:/seckill/list";
}
model.addAttribute("seckill", seckill);
return "detail";
}
/**
* 暴露秒杀接口的方法.
*
* @param seckillId 秒杀商品的id
* @return 根据用户秒杀的商品id进行业务逻辑判断,返回不同的json实体结果
*/
@RequestMapping(value = "/{seckillId}/exposer", method = RequestMethod.GET)
@ResponseBody
public SeckillResult<Exposer> exposer(@PathVariable("seckillId") Long seckillId) {
// 查询秒杀商品的结果
SeckillResult<Exposer> result;
try {
Exposer exposer = seckillService.exportSeckillUrl(seckillId);
result = new SeckillResult<>(true, exposer);
} catch (Exception e) {
e.printStackTrace();
result = new SeckillResult<>(false, e.getMessage());
}
return result;
}
/**
* 用户执行秒杀,在页面点击相应的秒杀连接,进入后获取对应的参数进行判断,返回相对应的json实体结果,前端再进行处理.
*
* @param seckillId 秒杀的商品,对应的时秒杀的id
* @param md5 一个被混淆的md5加密值
* @param userPhone 参与秒杀用户的额手机号码,当做账号密码使用
* @return 参与秒杀的结果,为json数据
*/
@RequestMapping(value = "/{seckillId}/{md5}/execution", method = RequestMethod.POST)
@ResponseBody
public SeckillResult<SeckillExecution> execute(@PathVariable("seckillId") long seckillId,
@PathVariable("md5") String md5,
@CookieValue(value = "userPhone", required = false) Long userPhone) {
// 如果用户的手机号码为空的说明没有填写手机号码进行秒杀
if (userPhone == null) {
return new SeckillResult<>(false, "没有注册");
}
// 根据用户的手机号码,秒杀商品的id跟md5进行秒杀商品,没异常就是秒杀成功
try {
// 这里换成储存过程
SeckillExecution execution = seckillService.executeSeckill(seckillId, userPhone, md5);
return new SeckillResult<>(true, execution);
} catch (RepeatKillException e1) {
// 重复秒杀
SeckillExecution execution = new SeckillExecution(seckillId, SeckillStatEnum.REPEAT_KILL);
return new SeckillResult<>(false, execution);
} catch (SeckillCloseException e2) {
// 秒杀关闭
SeckillExecution execution = new SeckillExecution(seckillId, SeckillStatEnum.END);
return new SeckillResult<>(false, execution);
} catch (SeckillException e) {
// 不能判断的异常
SeckillExecution execution = new SeckillExecution(seckillId, SeckillStatEnum.INNER_ERROR);
return new SeckillResult<>(false, execution);
}
// 如果有异常就是秒杀失败
}
/**
* 获取服务器端时间,防止用户篡改客户端时间提前参与秒杀
*
* @return 时间的json数据
*/
@RequestMapping(value = "/time/now", method = RequestMethod.GET)
@ResponseBody
public SeckillResult<LocalDateTime> time() {
LocalDateTime localDateTime = LocalDateTime.now();
return new SeckillResult<>(true, localDateTime);
}
}建立一个全局ajax请求返回类,返回json类型
SeckillResult:
package com.suny.dto;
/**
* 封装所有的ajax请求返回类型,方便返回json
* Created by 孙
*/
public class SeckillResult<T> {
private boolean success;
private T data;
private String error;
public SeckillResult() {
}
public SeckillResult(boolean success, T data) {
this.success = success;
this.data = data;
}
public SeckillResult(boolean success, String error) {
this.success = success;
this.error = error;
}
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
public String getError() {
return error;
}
public void setError(String error) {
this.error = error;
}
@Override
public String toString() {
return "SeckillResult{" +
"状态=" + success +
", 数据=" + data +
", 错误消息='" + error + '\'' +
'}';
}
}页面的编写
因为项目的前端页面都是由Bootstrap开发的,所以我们要先去下载Bootstrap或者是使用在线的CDN.
-Bootstrap中文官网：http://www.bootcss.com/
-Bootstrap中文文档 ：http://v3.bootcss.com/
使用在线CDN引入的方法:
<!-- 最新版本的 Bootstrap 核心 CSS 文件 -->
<link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<!-- 可选的 Bootstrap 主题文件（一般不用引入） -->
<link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/3.3.7/css/bootstrap-theme.min.css" integrity="sha384-rHyoN1iRsVXV4nD0JutlnGaslCJuC7uwjduW9SVrLvRYooPp2bWYgmgJQIXwl/Sp" crossorigin="anonymous">

- 首先下载
JQuery,因为Bootstrap就是依赖JQuery的 - 然后下载
Bootstrap - 然后下载一个倒计时插件
jquery.countdown.min.js-再下载一个操作Cookie插件jquery.cookie.min.js如图放置
- 首先编写一个公共的头部

<link rel="stylesheet" href="${pageContext.request.contextPath}/resources/plugins/bootstrap-3.3.0/css/bootstrap-theme.min.css" type="text/css">- 然后编写一个公共的

</html>然后把项目运行一下我们又会碰到一个错误就是jstl中的fmt标签格式化时间只能格式化java.Util.Date类型的日期跟时间,而在我们这里我么使用了java8的LocalDateTIme,所以解析时间会出异常,这时我们应该想到自己去实现jstl标签来自定义解析这个时间日期 自定义标签步骤如下:
- 在
/WEB-INF创建目录tags - 然后创建一个文件
localDateTime.tag在tags目录下localData.tag用来格式化日期localDataTime.tag用来格式化日期跟时间的组合,也就是数据库中的Timestamp类型 -然后在localDataTime.tag中写自己自定义的格式化流程
<%--格式化java8的LocalDatime,解决jstl不支持java8时间的问题--%>
<%@ tag body-content="empty" pageEncoding="UTF-8" trimDirectiveWhitespaces="true" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
<%-- 这里是定义页面使用标签中的属性设置,<tags:localDataTime dateTime="${sk.createTIme}"/> --%>
<%@ attribute name="dateTime" required="true" type="java.time.LocalDateTime" %>
<%@ attribute name="pattern" required="false" type="java.lang.String" %>
<%--首选判断日期时间转换规则是否存在,不存在给出默认的规则--%>
<c:if test="${empty pattern}">
<c:set var="pattern" value="yyyy-MM-dd HH:mm:ss"/>
</c:if>
<c:set var="datetime" value="${dateTime}"/> <%-- 获取jsp页面传入的【 日期时间 】,格式为【 2017-5-26T13:59:12 】 --%>
<c:set var="time" value="${fn:substringAfter(datetime, 'T')}"/> <%-- 获取页面传过来的【时间T】后面的 【 时:分:秒 】的值 --%>
<c:set var="timeLength" value="${fn:length(time)}"/> <%-- 获取页面传来的 【 时:分:秒 的长度 】 --%>
<c:set var="generalLength" value="${fn:length('123456')}"/> <%-- 这里定义了一个【Integer】类型的值,值为字符串 【123456 】的长度 --%>
<c:set var="cloneZero" value=":00"/> <%-- 这里设置一个值为【String】的字符串, --%>
<%-- 当 时:分:秒 不足6位的时候就说明缺少秒,我们给它自动补充 :00 --%>
<c:if test="${timeLength lt generalLength}">
<c:set var="datetimeCloneZero"
value="${datetime}${cloneZero}"/> <%-- 拼接页面传过来的 【 时：分 】 ,补充一个【秒数】,EL中 + 为相加,非拼接字符串 --%>
<c:set var="cleandDateTime"
value="${fn:replace(datetimeCloneZero,'T',' ')}"/> <%-- 把java8日期时间中的【 T 】给去掉,换成一个空的字符串 --%>
</c:if>
<%-- 当页面传过来的时间大于6位时说明时间时完整的,不进行自动填充【 :00 】,直接把日期时间中的 【 T 】 替换为空字符串 --%>
<c:if test="${timeLength gt generalLength}">
<c:set var="cleandDateTime" value="${fn:replace(datetime,'T',' ')}"/>
</c:if>
<%-- 解析时间, type="BOTH"为同时解析日期跟时间 --%>
<fmt:parseDate value="${cleandDateTime}" var="parsedDateTime" pattern="${pattern}" type="BOTH"/>
<fmt:formatDate value="${parsedDateTime}" pattern="${pattern}" type="BOTH"/>localData.tag的内容就比较简单了
<%@ tag body-content="empty" pageEncoding="UTF-8" trimDirectiveWhitespaces="true" %>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ attribute name="date" required="true" type="java.time.LocalDate" %>
<%@ attribute name="pattern" required="false" type="java.lang.String" %>
<c:if test="${empty pattern}">
<c:set var="pattern" value="MM/dd/yyyy"/>
</c:if>
<fmt:parseDate value="${date}" var="parsedDate" type="date"/>
<fmt:formatDate value="${parsedDate}" type="date" pattern="${pattern}"/>- 然后我们去页面导入需要的标签,然后去使用,修改
list.jsp文件
<%@page contentType="text/html; charset=UTF-8" language="java" %>
<%@include file="common/tag.jsp" %>
<%@taglib prefix="tags" tagdir="/WEB-INF/tags" %>

<%@taglib prefix="tags" tagdir="/WEB-INF/tags" %><td><tags:localDataTime dateTime="${sk.startTime}"/></td>
<td><tags:localDataTime dateTime="${sk.endTime}"/></td>
<td><tags:localDataTime dateTime="${sk.createTIme}"/></td>然后我们的格式就应该可以正常被格式化出来了
