 项目中涉及的框架相关知识并不多，主要涉及了许多 Java 基础的知识，如：Java 程序编译和运行的过程、Java 类加载机制、Java 类文件结构、Java 反射等。除此之外，还涉及到了一个简单的并发问题：如何将一个非线程安全的类变为一个线程安全的类。因此，本项目较为适合在比较注重基础的面试中介绍给面试官，可以引出一些 Java 虚拟机，Java 并发相关的问题，较能体现应聘者对于 Java 的一些原理性的知识的掌握程度。在本篇文章中，我们尽可能的将用到的知识简单讲解一下或者给出讲解的链接，以方便大家阅读。

+1. 基于注解实现类似spring的controller的注解；
+1. 类似SpringBoot的Application启动接口。
+1. 系统运行日志
+1. 完善页面
