	"github.com/jinzhu/copier"
)

type Person struct {
	Name string
	Age  int
}

type Student struct {
	Name string
	Age  int
	ID   int
}

func main() {
	person := &Person{Name: "张三", Age: 30}
	student := &Student{}

	copier.Copy(student, person) // 将person的属性复制到student中

	fmt.Println(student) // 输出：&{张三 30 0}
}
