## 介绍 ##

> logback是java的日志开源组件，是log4j的作者开发的用来替代log4j的。
> 
> logback由三个部分组成，logback-core, logback-classic, logback-access。
> 
> 其中logback-core是其他两个模块的基础。
> 
> logback-classic：它是log4j的一个改良版本，同时它完整实现了slf4j API，使我们可以在其他日志系统，如log4j和JDK14 Logging中进行转换。
> 
> logback-access：访问模块和Servlet容器集成，提供通过Http来访问日志的功能
