Spring MVC错误404错误的请求Kotlin

我正在使用Kotlin开发Spring MVC应用程序。
我有一个简单的表单,当我提交时,我得到错误404错误的请求 。 我使用的Jetty服务器和Intellij社区版 。我试过调试,但因为我从来没有调试过的Web应用程序,它不是那么有用。

web.xml中

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <servlet> <servlet-name>frontDispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>frontDispatcher</servlet-name> <url-pattern>/springkotlinmvc/*</url-pattern> </servlet-mapping> </web-app> 

frontDispatcher-servlet.xml中

 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context = "http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> <context:annotation-config/> <mvc:annotation-driven/> <context:component-scan base-package="org.manya.kotlin"/> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans> 

DataClasses.kt

 package org.manya.kotlin data class Address (val city : String, val state : String) data class Student ( val name : String , val age : Int, val address : Address) 

StudentController.kt

 package org.manya.kotlin import org.springframework.stereotype.Controller import org.springframework.web.bind.annotation.* import org.springframework.web.servlet.ModelAndView @Controller @RequestMapping("/student") class StudentController { //@GetMapping("/student/form") @GetMapping("form") fun studentForm() : ModelAndView{ println("called from studentForm()") return ModelAndView("form") } //@PostMapping("springkotlinmvc/student/submitted") //@RequestMapping(value = "/student/submitted" , method = arrayOf(RequestMethod.POST)) //@RequestMapping("/submitted") @PostMapping("/submitted") fun submitted(@ModelAttribute("student") stud : Student) : ModelAndView { println("called from submitted()") return ModelAndView("submitted") } } 

这里的方法studentForm()完全被映射到视图(form.jsp),但提交的方法没有得到映射。

form.jsp

 <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <form action="./submitted" method="post"> NAME : <input id="name"/> AGE : <input id="age"/> CITY : <input id="address.city"/> STATE : <input id="address.state"/> <input type="submit"/> </form> </body> </html> 

检查你的链接404意味着没有找到,这可能是由于在这里没有指向root ./submitted ,改为${pageContext.request.contextPath}/foo或者配置WEB-INF位置。

我在代码中发现了错误,这是一个小错误,但是由于我在Web领域的知识不足,我并没有意识到这一点。

在form.jsp中,我以给所有输入元素赋予id属性的形式。 我改变这些名称 ,它工作正常。
