java - Spring Jsp中使用简单表单的问题

问题描述

我从 ->>> https://www.baeldung.com/spring-mvc-form-tutorial创造了一些魔力

而且我不知道为什么，但是代码不起作用。

我试图更改目录、名称、添加奇怪的属性，但一切都失败了。

spring.view.prefix= /WEB-INF/jsp/
spring.view.suffix= .jsp

表单.jsp

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<html>
    <head>
    </head>
    <body>
        <form:form method="POST"
          action="${pageContext.request.contextPath}/addFlightDTO" modelAttribute="FlightDTO">
             <table>
                <tr>
                    <td><form:label path="DateFrom">DateFrom</form:label></td>
                    <td><form:input path="DateFrom"/></td>
                </tr>
                <tr>
                    <td><form:label path="DateTo">DateTo</form:label></td>
                    <td><form:input path="DateTo"/></td>
                </tr>
                <tr>
                    <td><form:label path="Origin">Origin</form:label></td>
                    <td><form:input path="Origin"/></td>
                </tr>

                  <tr>
                     <td><form:label path="Departure">Departure</form:label></td>
                     <td><form:input path="Departure"/></td>
                   </tr>


                   <tr>
                     <td><form:label path="currency">currency</form:label></td>
                     <td><form:input path="currency"/></td>
                   </tr>





                <tr>
                    <td><input type="submit" value="Submit"/></td>
                </tr>
            </table>
        </form:form>
    </body>
</html>

public class FlightDTO {
    private String DateFrom;
    private String DateTo;
    private String Origin;
    private String Departure;
    private Double currency;
getters, setters ...

@Controller
public class FormController {



        @RequestMapping(value = "/FlightDTO", method = RequestMethod.GET)
        public ModelAndView showForm() {
            return new ModelAndView("Forms", "FlightDTO", new FlightDTO());
        }

        @RequestMapping(value = "/addFlightDTO", method = RequestMethod.POST)
        public String submit(@Valid @ModelAttribute("FlightDTO")FlightDTO flightDTO,
                             BindingResult result, ModelMap model) {
            if (result.hasErrors()) {
                return "error.jsp";
            }
            model.addAttribute("DateFrom", flightDTO.getDateFrom());
            model.addAttribute("DateTo", flightDTO.getDateTo());
            model.addAttribute("currency", flightDTO.getCurrency());
            return "Results";
        }
    }

错误信息

THYMELEAF][http-nio-8080-exec-5] Exception processing template "Forms": Error resolving template [jsp/Forms], template might not exist or might not be accessible by any of the configured Template Resolvers

===============================================

我尝试了不同的解决方案。我看不出我的代码与指南中的代码有任何区别。

要运行表单，我使用以下两个链接：

http://localhost:8080/FlightDTO
http://localhost:8080/flight-radar/FlightDTO

请帮忙 ：）
