Admin.Admin/Login --- 后台项目中的管理员及登录模块的相关文章

maven多module项目中千万不要引入其他模块的单元测试代码

本文出处:http://blog.csdn.net/chaijunkun/article/details/35796335,转载请注明.由于本人不定期会整理相关博文,会对相应内容作出完善.因此强烈建议在原始出处查看此文. 这两天一直在整理一些旧的代码,将原来的混乱东西升级到maven管理.这其中也免不了将大项目拆分成若干个module(这里纠正一个发音,不是"猫丢",是['mɑ?d?ul],包阔我在内很多人都念错)来管理.然而为了在测试的时候图省事,在各个模块都引用的基础module中

项目中常用到思科的模块

思科的模块有很多,在项目中经常用到的有以下几种.一.千兆模块1.千兆单模模块大体样式如下图:GLC-LH-SMD:单模10KM模块,工作温度-5°C to 85°C .GLC-EX-SMD:单模40KM模块,工作温度-5°C to 85°C .GLC-ZX-SMD:单模70KM模块,工作温度-5°C to 85°C .2.千兆多模模块GLC-SX-MMD:多模模块,工作温度-5°C to 85°C .3.千兆光转电模块GLC-T:光口转电口,工作温度0 to 70°C.大体样式如下图:二.万兆模

在前后端分离的SpringBoot项目中集成Shiro权限框架

项目背景 公司在几年前就采用了前后端分离的开发模式,前端所有请求都使用ajax.这样的项目结构在与CAS单点登录等权限管理框架集成时遇到了很多问题,使得权限部分的代码冗长丑陋,CAS的各种重定向也使得用户体验很差,在前端使用vue-router管理页面跳转时,问题更加尖锐.于是我就在寻找一个解决方案,这个方案应该对代码的侵入较少,开发速度快,实现优雅.最近无意中看到springboot与shiro框架集成的文章,在了解了springboot以及shiro的发展状况,并学习了使用方法后,开始在网上

详解-vue项目中的文件和目录

可以用vue-cli来支持一个项目. 建议使用npm 3+更高效的依赖关系树: $ npm install -g vue-cli $ vue init webpack my-project $ cd my-project $ npm install $ npm run dev 项目结构: . ├── build/ # webpack配置文件 │ └── ... ├── config/ │ ├── index.js # 主要项目配置 │ └── ... ├── src/ │ ├── main.js

jNs 在 ASP.NET MVC 项目中的应用

最近做项目用到 ASP.NET Web Optimizatoin Framework,发现 Sea.js 的依赖加载在 Release 版本下不能很好的工作了--因为 Web.Optimizatoin 合并了所有脚本.同时由于写惯了 Java 程序和 C# 程序,对于没有命名空间概念的 Sea.js 和 RequireJS 也感觉不爽.考虑了下,觉得模块管理其实并不复杂,所以将之前在<ASP.NET MVC4 捆绑(Bundle)技术下的 JavaScript> 中提到的 js-modular

web 项目中a标签传值（中文）到后台的乱码问题

web 项目中a标签传值(中文)到后台的乱码问题 jsp页面中的a标签: .............. <c:forEach items="${sellerList }" var="seller" > <tr class="data-tr"> <td>${seller.order_number }</td> <td>${seller.name }</td> <td>

在vue-cli搭建的项目中在后台mock接口中支持req.body和req.cookies

在<vue-cli搭建的项目中增加后台mock接口>中实现了后台mock,但是前端post的t数据都要在mock的后台接口中使用req的接收数据事件获取http协议body中的数据. req.on('data', function(chunk){ //接收字节数据 }); req.end('data', function(){ //转换||处理 }); req.error('error', function(e){ //处理错误 }); 如果前端需要使用cookie,后端要读取,那么在后台mo

QTP校验数据库中数据后台项目
