私は春を始めたばかりなので、HerokuでSpringMVCから始めました。Eclipse で Spring MVC テンプレートを選択することで、非常に基本的なアプリケーションを作成できました。今、私はこれを変更しようとしています。
ただし、別の URL を作成.jspして Controller で指定された URL にアクセスすると、404 が返されます。これは、Controller を にマップしたことがないため、明らか.jspです。しかし、どうすればいいですか？
これが私が変更したすべてです（必要になるかどうかわからない場合でも）：
コントローラー:
@Controller
public class BookingController {
@Autowired
BookingService bookingService;
@RequestMapping("/AvailableBikes")
public String getAvailableBikes(Model model){
// TOOD: Fix Date
int availableBookings = bookingService.getAvailableBookings(Calendar.getInstance().getTime());
model.addAttribute("NumAvailableBikes", Integer.toString(availableBookings));
return "NumAvailableBikes";
}
}
エンティティ:
@Entity
public class Booking {
@Id
@GeneratedValue
private Integer id;
// Lots of getters setters an attributes ...
}
サービス：
@Service
public class BookingServiceImpl implements BookingService {
@Override
public void addBooking(Booking booking) {
// TODO Auto-generated method stub
}
@Override
public int getAvailableBookings(Date bookingDay) {
// TODO Auto-generated method stub
return 12;
}
@Override
public void removeBooking(Booking booking) {
// TODO Auto-generated method stub
}
}
