Aop介绍及几种实现方式

Aop介绍 我们先看一下wiki百科的介绍 Traditional software development focuses on decomposing systems into units of primary functionality, while recognizing that there are other issues of concern that do not fit well into the primary decomposition. The traditional development process leaves it to the programmers to code modules corresponding to the primary functionality and to make sure that all other issues of concern are addressed in the code wherever appropriate. Programmers need to keep in mind all the things that need to be done, how to deal with each issue, the problems associated with the possible interactions, and the execution of the right behavior at the right time. These concerns span multiple primary functional units within the application, and often result in serious problems faced during application development and maintenance. The distribution of the code for realizing a concern becomes especially critical as the requirements for that concern evolve – a system maintainer must find and correctly update a variety of situations.

模拟ASP.NET Core MVC设计与实现

前几天有人在我的《ASP.NET Core框架揭秘》读者群跟我留言说:“我最近在看ASP.NET Core MVC的源代码,发现整个系统太复杂,涉及的东西太多,完全找不到方向,你能不能按照《200行代码,7个对象——让你了解ASP.NET Core框架的本质》这篇文章思路剖析一下MVC框架”。对于ASP.NET Core MVC框架的涉及和实现,说难也难,毕竟一个Model Binding就够很多人啃很久,其实说简单也简单,因为整个流程是很清晰的。ASP.NET Core MVC支持基于Controller和Page的两种编程模式,虽然编程方式看起来不太一样,底层针对请求的处理流程其实是一致的。接下来,我同样使用简单的代码构建一个Mini版的MVC框架,让大家了解一下ASP.NET Core MVC背后的总体设计,以及针对请求的处理流程。[源代码从这里下载]。
