LogbackUtil 自定义logback日志框架
1、前言
logback原有的日志功能不满足项目的需求,需将日志按功能模块输出
2、说明
1、使用需配置父目录 parentDir
,也就是主目录,
2、配置日志路径,功能模块名为子文件夹,模块名+日期+日志级别为文件名称
3、使用.txt
后缀,方便文本编辑器打开,具体细节,酌情配置。
/*日志路径*/
String fp = OptionHelper.substVars(parentDir + "/" + name + "/" + name + " %d{yyyy_MM_dd} .%i. " + level.levelStr.toLowerCase() + ".txt", context);
