javax.servlet.ServletException: 无法在名称为 'travel' 的 servlet 中解析名称为 'hotels/booking/enterBookingDetails' 的视图

Question

我试过在 Whosebug 上查看几个类似的问题，但无法真正理解！这是我的第一个 Spring 应用程序，对于可能重复的问题，我深表歉意。非常感谢任何帮助。

当我导航到 enterDetails 页面时出现以下错误：-

Exception thrown by application class 'org.springframework.web.servlet.DispatcherServlet.render:1029'
javax.servlet.ServletException: Could not resolve view with name 'hotels/booking/enterBookingDetails' in servlet with name 'travel'

这是控制器：-

@RequestMapping(value = "hotels/booking", method = RequestMethod.GET)
public String bookingDetails(@RequestParam Long hotelId, Model model) {     
    Booking booking = bookingService.createBooking(hotelId,"keith");
    model.addAttribute(booking);
    return "hotels/booking/enterBookingDetails";
}

我是新来的，但我一直在从事一些 spring MVC 项目。所以希望对解决你的问题有所帮助

我会更改您的控制器，使其能够使用 ModelAndView 对象，因此您可以执行以下操作：

    @RequestMapping(value = "hotels/booking", method = RequestMethod.GET)
    public ModelAndView bookingDetails(@RequestParameter Long hotelId) {  

    ModelAndView model = new ModelAndView("enterBookingDetails");
    Booking booking = bookingService.createBooking(hotelId,"keith");
    model.addObject("booking", booking);
    return model;
}
