简单工具类
写作初衷:由于日常开发经常需要用到很多工具类,经常根据需求自己写也比较麻烦 网上好了一些工具类例如commom.lang3或者hutool或者Jodd这样的开源工具,但是 发现他们之中虽然设计不错,但是如果我想要使用,就必须要引入依赖并且去维护依赖,有些 甚至会有存在版本编译不通过问题,故此想要写作一个每个类都可以作为独立工具类使用 每个使用者只需要复制该类,到任何项目当中都可以使用,所以需要尊从以下两个原则才能 做到.在此诚邀各位大佬参与.可以把各自用过的工具,整合成只依赖JDK,每个类都能够单独 使用的工具.每个人当遇到业务需求需要使用的时候,只需要到这里单独拷贝一个即可使用. 抛弃传统的需要引入依赖的烦恼.让大家一起来解决你所面临的业务问题吧!
介绍
遵从两大原则
- 1.绝不依赖JDK以外的源码
- 2.牺牲代码复用性,每个类都必须是单独的组件,绝不互相引用,做到完全解耦
