The Golang Log standard library implements a simple logging service. But does not support log classification, classification, filtering and other complex functions. By a third-party library such as Glog (Github), Seelog (Github) Simple demo is as follows: Package main Import ( "log" "OS ) Func main () {

Another week, the recent life, hhhe, the process of learning is really very slow, but slowly, not anxious, not afraid, not counseling.Recently wrote something, encapsulated a database operation of the package, but there is a big bug, temporarily not posted, because it has not been resolved. But the package of this log package, actually did not write complete, but feel go

Id = 8 when I use open-source projects, I pay more attention to activity. I wanted to write a module to solve the problem. Later I found seelog and tried it. It was good, the recommended configurations and habits are also consistent with those of log4x. Seelog Source Code addre

log4j output multiple custom log filesIf you need to output a separate log file in the actual application, how can you separate the required content from the original log and form a separate log file? First look at a common log4j
