 1 | # 手写SpringMVC
 2 |    ## 概述：
 3 |    本项目是为了探究SpringMVC底层原理，在学习之余自己实现了一个乞丐版SpringMVC。
 4 |    ## 功能实现：
 5 |    1.项目紧依赖于log4j日志包<br/>
 6 |    2.实现了RequestMapping、Controller、Service、Autowired注解。<br/>
 7 |    3.在配置文件中配置扫描包路径。<br/>
 8 |    4.实现了url到method的映射。<br/>
 9 |    5.对不存在页面的404处理，页面异常的500处理<br/>
10 |    ## 功能展示：
11 |    ### 这是项目结构：
