Log levels provide a way to categorize and identify logs based on their severity. 日志级别用来确定日志的严重程度,它可以用来过滤日志事件或者将其发送给不同的 Appender。 java.util.logging 框架提供了如下的日志级别: SEVERE (HIGHEST LEVEL) WARNING INFO CONFIG FINE FINER FINEST (LOWEST LEVEL) 创建新Log...
INFO 通常有用的信息要记录(服务开始/停止,配置假设等)。信息,我想总是有可用的,但通常不在乎在正常情况下。这是我开箱即用的配置级别 WARN 任何可能导致应用程序奇数,但我正在自动恢复。(例如从主服务器切换到备份服务器、重试操作、缺少次要数据等) ERROR 任何对操作致命但服务或应用程序(无法打开所需文件、丢失...

Java中的Log 1. Debug 通常情况下,Debug的级别最低(当然还有比它低的——Trace,All),一般来说,在应用实际上线运行时,都是不输出Debug Log的,因此可以在调试程序时使用,写程序时应该养成输出Log的良好习惯,这样可以在程序出现问题时及时的定位到错误的位置,同时别人阅读你的代码时,也很容易明白程序的运行流程,...
