+# logHelper
+
+### Reference Documentation
+该项目是用来测试与观察`RequestBodyAdviceAdapter`中的整个代码流程,以便判断是否能够做全局日志处理,功能实现只依赖以下包:
+* [Spring Web](https://docs.spring.io/spring-boot/docs/2.5.2/reference/htmlsingle/#boot-features-developing-web-applications)
+
+如果你跟我一样觉得做一个日志打印,还有引入`AOP`这么多包,可以考虑使用`spring-mvc`中的相关功能去实现对应逻辑
