logback xml sample

logback.xml推荐配置

这里是个人使用的logback配置。

  • logpath：设置日志文件的存储路径
  • patt_*：日志的格式
    • patt_debug：开发调试环境下使用，它最大的优势是在eclipse的控制台上打印出来的日志，有明显的代码行号跳转链接，鼠标点击后可以直接跳到代码位置。
    • patt_pro：生产环境配置，也带有【代码运行位置】。
      注意，【代码运行位置】特性会带来性能上的损耗，在高并发下这个影响比较明显。但是一般人都不会遇到很多高并发，一般建议加上，因为对于排查问题很有用。
    • patt_fast：生产环境配置的高速版，去除了【代码运行位置】
    • patt_simple：只打印消息本身，适用于做记录业务信息。
  • append建议开启sync模式，一般是有益无害。
  • 在刚接手项目时候，一定要把Spring的RequestMappingHandlerMapping和AutoConfigurationReportLoggingInitializer的日志打开，这里坑巨多。
    如果用了数据库，也最好把Spring的数据库事务日志打开，因为你不知道别人会怎么配置的。

logback.xsd

这个不是官方推荐的，但是使用之后对于编辑logback.xml非常方便。

使用方法：放在logback.xml一起。
