Question

我在SpringMVC项目中收到此错误。我必须在浏览器中手动添加完整路径才能运行代码，但我无法直接运行。

     org.springframework.web.servlet.DispatcherServlet noHandlerFound
            WARNING: No mapping found for HTTP request with URI [/SpringMVC/] in DispatcherServlet  with name 'SpringMVC'

的web.xml：

            <?xml version="1.0" encoding="UTF-8"?>
            <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

            <servlet>
            <servlet-name>SpringMVC</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <load-on-startup>1</load-on-startup>
            </servlet>
            <servlet-mapping>

            <url-pattern>/</url-pattern>
            </servlet-mapping>
            </web-app>

用SpringMVC-servlet.xml中：

            <?xml version="1.0" encoding="UTF-8"?>
            <beans xmlns="http://www.springframework.org/schema/beans"
            xmlns:context="http://www.springframework.org/schema/context"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="
            http://www.springframework.org/schema/beans     
            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
            http://www.springframework.org/schema/context 
            http://www.springframework.org/schema/context/spring-context-3.0.xsd">

            <context:component-scan base-package="com.adept.springMVC"></context:component-scan>
            <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="suffix" value=".jsp"></property>

            </bean>

            </beans>

StudentControler.java：

            package com.adept.springMVC;

            import org.springframework.stereotype.Controller;
            import org.springframework.ui.ModelMap;
            import org.springframework.web.bind.annotation.ModelAttribute;
            import org.springframework.web.bind.annotation.RequestMapping;
            import org.springframework.web.bind.annotation.RequestMethod;
            import org.springframework.web.servlet.ModelAndView;
            @Controller
            public class StudentControler {
            @RequestMapping(value="/student1",method=RequestMethod.GET)
            public ModelAndView student1(){
            return new ModelAndView("student", "command", new Student());
            }
            @RequestMapping(value="/addStudent",method=RequestMethod.POST)
            public String addStudent(@ModelAttribute("springWeb1")Student stud,ModelMap map){
            map.addAttribute("name",stud.getName());
            map.addAttribute("id", stud.getId());
            map.addAttribute("dept", stud.getDept());
            return "result";
            }
           }

student.jsp：

            <%@ page language="java" contentType="text/html; charset=UTF-8"
            pageEncoding="UTF-8"%>
            <%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

            <form:form method="post" action="/SpringMVC/addStudent">

            <tr>
            <td><form:label path="name">Name:</form:label></td>

            </tr>
            <tr>

            </tr>
            <tr>
            <td colspan="2">
            <input type="submit" value="Submit"/>
            </td>
            </tr>

            </form:form>

            </body>
            </html>

result.jsp中：

            <h1>Student Information</h1>
            <table>
            <tr>

            </tr>
            </table>  
            </body>
            </html>

请告诉我如何解决问题。

Answer 1

将springMVC-servlet.xml更改为大写S SpringMVC-servlet.xml

Answer 2

我认为您的应用程序上下文路径是“ /”，而不是“ SpringMVC”。您的请求uri不需要“ / SpringMVC”，例如“ http://localhost:8080/student1”

Answer 3

更改您的应用程序 pom.xml


 <properties>
       <springframework.version>4.0.6.RELEASE</springframework.version>
  </properties>
