@PostMapping("/items/new")
public String create(BookForm form){
Book book = new Book();
book.setName(form.getName());
book.setPrice(form.getPrice());
book.setStockQuantity(form.getStockQuantity());
book.setAuthor(form.getAuthor());
book.setIsbn(form.getIsbn());

@GetMapping("/items")
public String list(Model model){
List<Item> items = itemService.findItems();
model.addAttribute("items", items);
return "items/itemList";
}
}생성,
그러니까 Post해서 받을 때,
저렇게 setter 밖으로 표출되는 거 안 좋고 createBook 같은 static 메소드 넣어서 만드셈.
그 다음 PRG. 재요청 안하게끔.
조회는 간단함.
@Getter @Setter
public class BookForm {
private Long id;
private String name;
private int price;
private int stockQuantity;
private String author;
private String isbn;
