func main(t *testing.T) {
	container.Register("config", Config.New())
	container.Register("logger",	Logger.New())
	// container.Register("database", Database.New())
	container.Register("service.user", UserService.New())

package config

import (
	cfg "github.com/go-zoox/config"
)

type Config struct {
	Database struct {
		Host string
		Port int
	}
	Logger struct {
		Level string
	}
}

func New() *Config {
	var c Config

}

// service/user.go
package service

type UserService struct {
	Config *Config
	Logger *log.Logger
}


func New() *UserService {
	return &UserService{
		Config: container.MustGet("config").(*Config),
		Logger: container.MustGet("logger").(*log.Logger),
	}
}

func (u *UserService) GetUser(id int) (*User, error) {
	u.Logger.Info("GetUser")

	return &User{
		ID: id,
