Cd 进入项目目录
go get gopkg.in/natefinch/lumberjack.v2
go install gopkg.in/natefinch/lumberjack.v2
go get go.uber.org/zap
关于下面代码说明:
func getLogWriter() zapcore.WriteSyncer { lumberJackLogger := &lumberjack.Logger{ Filename: "../logs/log.log", // 日志文件的位置 MaxSize: 1, // 在进行切割之前,日志文件的最大大小(以MB为单位) MaxBackups: 5, // 保留旧文件的最大个数 MaxAge: 30, // 保留旧文件的最大天数 Compress: false, // 是否压缩/归档旧文件 } return zapcore.AddSync(lumberJackLogger) }
具体实现代码
