SpringBoot整合后端项目-2.集成logback

前言

该系列文章，是我从零搭建一套后端项目的经验总结。
没有过多的流程梳理和细节描写，目的也是对所学技术的一个总结和巩固。
内容大多包括实现思路，实现要点、注意事项和一些个人心得，希望对各位看官有所帮助。

注意事项

1.配置文件中只要有错误，启动项目的时候，控制台就会为空，且项目启动不了。有的错误不会有任何提示，比如一个下配置了多个，在从多处cv的情况下容易出现。这样的错误没有任何征兆，但是影响项目运行，需要多加小心。
2.命名为logback-spring.xml，放在resource目录下即可，不需要其他配置
3.可采用以下方式配置不同的环境
