logback介绍
Logback是由log4j创始人设计的又一个开源日志组件。logback当前分成三个模块：logback-core,logback- classic和logback-access。logback-core是其它两个模块的基础模块。logback-classic是log4j的一个 改良版本。此外logback-classic完整实现SLF4J API使你可以很方便地更换成其它日志系统如log4j或JDK14 Logging。logback-access访问模块与Servlet容器集成提供通过Http来访问日志的功能
想要学习logback，可以参照Logback用户手册中文版.pdf。
logback使用
- 先新建一个maven工程
- logback需要引入的jar包（slf4j-api-x.x.x.jar,logback-core-x.x.x.jar,logback-classic-1.0.0.jar,logback-access-x.x.x.jar）,maven的依赖关系如下：
