I have a log configuration, use ctx to add traceID, my log is executed output, but the added traceID is json, is there a way to change it?

package httplog
import (
"context"
"fmt"
rotatelogs "github.com/lestrrat-go/file-rotatelogs"
"go.uber.org/zap"
"go.uber.org/zap/zapcore"
"io"
"time"
)

const traceId = iota

var Logger *zap.Logger

func Init(path string) {
if len(path) == 0 || path == "" {
panic("init log fail,logpath can not nil")
}
encoder := zapcore.NewConsoleEncoder(zapcore.EncoderConfig{
MessageKey: "msg",
LevelKey: "level",
EncodeLevel: zapcore.CapitalLevelEncoder,
TimeKey: "ts",
EncodeTime: func(t time.Time, enc zapcore.PrimitiveArrayEncoder) {
enc.AppendString(t.Format("2006-01-02 15:04:05"))
},
CallerKey: "file",
EncodeCaller: zapcore.ShortCallerEncoder,
EncodeDuration: func(d time.Duration, enc zapcore.PrimitiveArrayEncoder) {
enc.AppendInt64(int64(d) / 1000000)
},
LineEnding: zapcore.DefaultLineEnding,
})

infoLevel := zap.LevelEnablerFunc(func(lvl zapcore.Level) bool {
	return lvl >= zapcore.DebugLevel
})

warnLevel := zap.LevelEnablerFunc(func(lvl zapcore.Level) bool {
	return lvl >= zapcore.WarnLevel
})

log_path := fmt.Sprintf("%s/logs/demo.log", path)
err_path := fmt.Sprintf("%s/logs/demo.log.wf", path)
fmt.Println(log_path)
infoWriter := getWriter(log_path)
warnWriter := getWriter(err_path)

core := zapcore.NewTee(
	zapcore.NewCore(encoder, zapcore.AddSync(infoWriter), infoLevel),
	zapcore.NewCore(encoder, zapcore.AddSync(warnWriter), warnLevel),
)

Logger = zap.New(core, zap.AddCaller())
zap.ReplaceGlobals(Logger)
defer Logger.Sync()

}

func getWriter(filename string) io.Writer {
hook, err := rotatelogs.New(
filename+".%Y%m%d%H",
rotatelogs.WithLinkName(filename),
rotatelogs.WithMaxAge(time.Hour247),
rotatelogs.WithRotationTime(time.Hour),
)

if err != nil {
	panic(err)
}
return hook

}

func NewContext(ctx context.Context, fields ...zapcore.Field) context.Context {

return context.WithValue(ctx, traceId, WithContext(ctx).With(fields...))

}

func WithContext(ctx context.Context) *zap.Logger {
if ctx == nil {
return Logger
}
if ctxLogger, ok := ctx.Value(traceId).(*zap.Logger); ok {

	return ctxLogger
}
return Logger

}

actual output
2023-07-18 10:04:33 INFO logs/main.go:42 aaaa {"traceId": "5e4ead22-465f-479d-8700-27294944ebd0"}
expected output

or
