人生没有 i f,所以这个框架来了，一直有写个框架的想法(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，熬了几夜，也算是没有白熬夜!!!
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，目的为了更好的去理解框架本身。
没有冗长的调用链(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
