日志框架
日志技术的概述
生活中的日志： 生活中的日志就好比日记，可以记录你生活的点点滴滴。
程序中的日志： 程序中的日志可以用来记录程序运行过程中的信息，并可以进行永久存储
日志技术体系结构
日志的规范是什么，常见的有几种形式
日志规范大多是一些接口，提供给实现框架去设计的。
常见的规范是：
Commons Logging
Simple Logging Facade for Java
日志的实现框架有哪些常见的？
Log4J
Logback(我们重点学习的，其他的都大同小异)
Logback概述
使用Logback需要使用哪几个模块，各自的作用是什么
slf4j-api：日志规范
logback-core：基础模块。
logback-classic：它是log4j的一个改良版本，同时它完整实现了slf4j API
