目标功能：
    根据日志级别进行不同文件存储
    将error以下级别添加到info.log文件中
    将error及以上添加到error.log文件中

下载： go get -u go.uber.org/zap

github源码：[https://github.com/uber-go/zap][https_github.com_uber-go_zap]

func main() {
    	logger,err  := getLogger("D:/log/info.log","D:/log/error.log")
    	if err != nil {
    		log.Fatal(err)
    	}
    
    	logger.Debug("i am debug",zap.String("key","debug"))
    	logger.Info("i am info",zap.String("key","info"))
    	logger.Error("i am error",zap.String("key","error"))
    }
    
    func getLogger(infoPath,errorPath string)  (*zap.Logger,error) {
    	highPriority := zap.LevelEnablerFunc(func(lev zapcore.Level) bool{
    		return lev >= zap.ErrorLevel
    	})
    
    	lowPriority := zap.LevelEnablerFunc(func(lev zapcore.Level) bool {
    		return lev < zap.ErrorLevel && lev >= zap.DebugLevel
    	})
    
    
    	prodEncoder := zap.NewProductionEncoderConfig()
    	prodEncoder.EncodeTime = zapcore.ISO8601TimeEncoder
    
    
    	lowWriteSyncer,lowClose,err :=  zap.Open(infoPath)
    	if err != nil {
    		lowClose()
    		return nil,err
    	}
    
    
    	highWriteSyncer,highClose,err :=  zap.Open(errorPath)
    	if err != nil {
    		highClose()
    		return nil,err
    	}
    
    	highCore := zapcore.NewCore(zapcore.NewJSONEncoder(prodEncoder),highWriteSyncer,highPriority)
    	lowCore := zapcore.NewCore(zapcore.NewJSONEncoder(prodEncoder),lowWriteSyncer,lowPriority)
    
    
    	return  zap.New(zapcore.NewTee(highCore,lowCore),zap.AddCaller()),nil
