本文详细介绍了如何使用Logback进行日志配置，包括控制台输出、按日生成日志文件、根据级别过滤日志等高级配置，并提供了具体示例。

为什么80%的码农都做不了架构师？>>>

使用到的jar：

由于新增了可以动态生成文件的功能，jar需要升级到1.1.7(core/classic/slfj-api)

MDC.put("logFileName", "399001.SZ");

log.warn("aaaaaaaaa");

MDC.remove("logFileName");

MDC.put("logFileName", "000001.SS");

log.warn(HsRecord.gtJson("bbbbbbbbbb");

MDC.remove("logFileName");
