使用"github.com/sirupsen/logrus"、“github.com/rifflock/lfshook”、"github.com/lestrrat-go/file-rotatelogs"三个库进行项目的日志管理
"github.com/rifflock/lfshook"是一个用于将日志记录到本地文件系统的Golang库。 它提供了一个钩子(hook)来扩展Golang的标准日志库,使得在日志记录时可以将日志信息写入到本地文件系统中
"github.com/sirupsen/logrus"用来记录日志
"github.com/lestrrat-go/file-rotatelogs"它提供了一个钩子(hook)来扩展标准的日志库,实现日志文件的滚动记录
logger.InitLog(“log”, “log”, 10241024100, time.Hour247)
logPath:日志保存目录
logName:日志保存文件名
10241024100 : 日志保存滚动大小,这个100是100M
time.Hour247:最大日志保留日期,超过这个日期则进行清理
logger文件

初始化文件
package main
import (
"fmt"
log "github.com/sirupsen/logrus"
"test/core/logger"
"time"
)
// 在程序初始化的时候,进行初始化一下就可以了
func main() {
logger.InitLog("log", "log", 1024*1024*100, time.Hour*24*7)
for {
time.Sleep(time.Millisecond * 100)
log.Info(fmt.Sprintf("11111111111111111111111111111111111111111111111111"))
}
