一个没有 if 的Spring++框架就是这么肝

人生没有 i f,个没肝所以这个框架来了，一直有写个框架的框架想法(每个程序员都有的冲动)!怎么也磨灭不了，这次终于得以了了心愿!肝了几天，个没肝熬了几夜，框架也算是个没肝没有白熬夜!!!

首先先介绍一下这个框架的用途(先别吐槽，或许真的框架不是重复造轮子,技术这东西学到手,才是核心技术,否则被卡脖子——蹭个热度)

直接入主题吧!这也是打工人必备的品质!

简述：一个类似spring+spingBoot+mybatis 可耦可拆 的一个web 框架

主要涉及的技术有

cglib 动态代理 gradle 构建工具 netty 各种设计模式 责任链 工程 模板 策略 没有用" i f " 只用lambda

具体实现的功能或者思想有

ioc di 也就是大名鼎鼎的 依赖注入 aop 面向切面编程 mybatis 动态代理 拦截器 过滤器 循环依赖 区别于spring 的实现

说实话这是个面向函数式编程的工程，需要有函数式编程基础这也是个没肝重点

虽说还有些bug不过已经是好的开始!!!期待你的建议

先来个启动类

是的这和SpringBoot的启动是一样的简洁，也是云服务器提供商框架我的追求

主体代码本着论文的思路先摘要

逻辑那不是一般的清晰 关键还有注释 或许我就是适合这样清晰代码

扯扯设计想法

注释很清晰

逻辑也很清晰 主要也是为了需要的人更好的理解 学的东西太多 可是都是一知半解

面向对象设计

考虑前期的不足也尽量预留后期升级 或许这就是如果(" i f ")

方便dug

简单说就是每次方法总会返回下一次运行的条件，中间没有缓存，个没肝目的框架为了更好的去理解框架本身。

没有冗长的个没肝调用链(那 谁谁的框架源码堆栈一堆)你的痛我懂的

注解都是你所熟悉的

正如开始类至简，所有的框架注解都是和Spring或者SpringBoot 或者Mybatis一致方便你理解源码

Load.XXYY(arg) 

发现没有好多方法都是这个开头的 是的香港云服务器它再说 加载啦....加载啦.....加载啦....

喜欢这种 见名知意

不足的注释会定期增加的

有兴趣一起开荒 也许走着走着 就会跑了 跑了跑了 就会✈✈✈ 思想开小差啦 欢迎加入

不友好的地方

lambda 函数式编程不好调试 gradle 目前还不是web端的主流构建工具 可能跟着SpringBoot新版的路子啦停不下来了

下面是目录结构

hioove-core是框架的核心代码 hioove-demo是框架的测试代码

详细的还是看代码再说啦

粗看看核心代码
