【问题描述】：
我刚从 Spring 开始，所以我从 Heroku 上的 SpringMVC 开始。通过在 Eclipse 中选择 Spring MVC 模板，我得到了一个非常基本的应用程序。现在我正在尝试修改它。
但是，如果我创建另一个 .jsp 并访问控制器中给出的 URL，我会得到 404，这很清楚，因为我从未将控制器映射到 .jsp。但是我该怎么做呢？
这是我更改的所有内容（即使我不确定您是否需要它）：
控制器：
@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";
}
}
实体：
@Entity
public class Booking {
@Id
@GeneratedValue
private Integer id;
// Lots of getters setters an attributes ...
}
服务：
@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
}
}
booking.jsp：
<!doctype html>
<%@taglib uri="http://www.springframework.org/tags" prefix="spring"%>
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
