-如何应对互联网大并发 ， 如何利用缓存， 如何使用异步 ， 如何编写优雅的代码
-
-一： springboot 环境搭建 （springmvc会有大量的配置）
-
-1. 新建project -- maven -- 选择 maven-archtype-quickstart 项目
-2.pom.xml文件
-主要的 springboot的pom文件 項目直接导入就可以

-类的构思讲解：
-Result类：
-结果类Result 类封装成一个通用类，用一个codemsg错误码来直接返回，不需要每次返回再去new一个对象，按照模块来定义错误码
-
-Redis类：
-
-自己封装的 jedis ,使用它自带的temple总觉得不太好使
-1.　添加　jedis　依赖　2.添加　fastjson 依赖　json明文可读
-
-redis 通用缓存类封装　：
-
-接口　　－－　抽象类　－－　实现类　（模板模式）
-
- 模板模式的优点
-
-①具体细节步骤实现定义在子类中，子类定义详细处理算法是不会改变算法整体结构。
-②代码复用的基本技术，在数据库设计中尤为重要。
-③存在一种反向的控制结构，通过一个父类调用其子类的操作，通过子类对父类进行扩展增加新的行为，符合“开闭原则”。
-缺点：　每个不同的实现都需要定义一个子类，会导致类的个数增加，系统更加庞大。
-
-springboot　注解讲解：
-
-@ConfigurationProperties(prefix="redis")　　可以读取以redis配置开头的文件
-
-
-
-密码 --MD5 二次明文加密处理 设计
-
-密码设计：  MD5（MD5（pass明文 + 固定salt） + salt） 处理
-
-二次MD5：
-
-用户端： PASS = MD5 (明文 + 固定 Salt)
-
-服务端： PASS = MD5(用户输入 + 随机Salt)
-
-Js 前端进行第一个MD5 ， 后端进行第二次 ， 后端第二次salt随机生成入库，然后登录时取出对比
-
-
-注解JSR303与自定义注解来完成手机号和登录验证　　＋　全局异常处理器
-
-分布式session ：（处理请求落在不同服务器上）
-
-－－　核心在于把自动生成的token放在缓存当中用来记录用户　（redis　＋　cookie）
-
-登录成功之后给用户生成一个类似于sessionid的东西 token 标识用户写到cookie当中传递给客户端
-客户端在随后的访问中都在cookie中上传这个token ， 然后在服务端拿到这个token来取到用户信息
-把token uuid标识 存到 redis缓存中 ，设置过期时间，然后别的页面访问的时候依旧根据这个cookie token的值拿到用户信息。
-
-
-页面静态化,前后端分离,唯一索引解决卖超的问题　，　对象级缓存
-秒杀页面：
-
-１．数据库２．商品列表页３．商品详情页４．订单详情页
-
-解决超卖问题：
-数据库加唯一索引防止用户重复购买
-sql加库存数量判断防止库存变成负数　　mycat
-redis 预减库存减少数据库访问　内存标记减少redis访问　请求先入队列缓冲，异步下单，增强用户体验
-
-接口防刷限流：
-
-如果有缓存的话 这个功能实现起来就和简单，在一个用户访问接口的时候我们把访问次数写到缓存中，在加上一个有效期。
-通过拦截器. 做一个注解 @AccessLimit 然后封装这个注解，可以有效的设置每次访问多少次，有效时间是否需要登录！

-数据库采用mybatis：

+### 前言
+大家好,之前在公司自己设计并开发了一套完整的秒杀系统，希望和大家分享一下，希望大家能从中收益，如果有意见和好的想法请加我！
+ ＱＱ:3341386488
+ 邮箱：ＱiuRunZe_key@163.com
+
+我会不断完善，希望大家有好的想法拉一个分支提高，一起合作！
+
+
+    觉得不错对您有帮助，麻烦右上角点下star以示鼓励！长期维护不易 多次想放弃 坚持是一种信仰 专注是一种态度！
+
+
+## 秒杀设计整体流程
+
+![整体流程](http://i2.bvimg.com/601558/886c867d6488dfc2.png)
+
+
+
+#### 需注意几点：
+ 1.如何解决卖超问题
+
+ ① sql加上判断如果防止数据变为负数<br>
+ ② 数据库加唯一索引防止用户重复购买<br>
+ ③ redis预减库存减少数据库访问　内存标记减少redis访问　请求先入队列缓冲，异步下单，增强用户体验
+
+
+2.如何解决分布式session<br>
+ ① 生成一个随机的uuid一类的写回到cookie中<br>
+ ② redis 内存写入<br>
+ ③ 下一个页面拿到uuid 内存取对象
+
+3.如何优雅解决接口防刷限流 <br>
+>
+如果有缓存的话 这个功能实现起来就和简单，在一个用户访问接口的时候我们把访问次数写到缓存中，在加上一个有效期。
+通过拦截器. 做一个注解 @AccessLimit 然后封装这个注解，可以有效的设置每次访问多少次，有效时间是否需要登录！
+
+4.通用缓存key的封装采用什么设计模式？<br>
+
+模板模式的优点<br>
+①具体细节步骤实现定义在子类中，子类定义详细处理算法是不会改变算法整体结构。<br>
+②代码复用的基本技术，在数据库设计中尤为重要。<br>
+③存在一种反向的控制结构，通过一个父类调用其子类的操作，通过子类对父类进行扩展增加新的行为，符合“开闭原则”。<br>
+缺点：　每个不同的实现都需要定义一个子类，会导致类的个数增加，系统更加庞大
+
+5.LVS , tomcat(apr) , keepalive 高可用 ？？？？ 未来更新 ？？<br>
+6.限流算法等未来更新
