위와 같은 오류로 bean을 못 찾는다고 하는데 원인이 뭘까요
1. BookServiceImpl.java
package kwang.ho.service.book;
@Service
public class BookServiceImpl implements BookService {
@Autowired
private BookMapper bookMapper;
@Override
public List<BookDto> selectBookListWithPaging(PagingVO pagingVO) throws Exception {
return bookMapper.selectBookListWithPaging(pagingVO);
}
}
2. BookService.interface
package kwang.ho.service.book;
public interface BookService {
List<BookDto> selectBookListWithPaging(PagingVO pagingVO) throws Exception;
}
3. BookMapper.interface
package kwang.ho.mapper.book;
public interface BookMapper{
List<BookDto> selectBookListWithPaging(PagingVO pagingVO) throws Exception;
}
4. BookController.java
package kwang.ho.controller.book;
@Controller
@RequiredArgsConstructor
public class BookController {
private final BookService bookService;
@RequestMapping("/bookList.do")
public String selectBookListWithPaging(PagingVO pagingVO, Model model
, @RequestParam(value="nowPage", required=false)String nowPage
, @RequestParam(value="cntPerPage", required=false)String cntPerPage, BookDto bookDto) throws Exception {
model.addAttribute("list", bookService.selectBookListWithPaging(pagingVO));
return "/bookList";
}
}
5. bookMapper.xml
