Question

我试图通过创建动态Web项目从头开始构建一个简单的Dispatcher Servlet示例。

这些是我的文件。

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    id="WebApp_ID" version="3.1">
    <display-name>flightReservation</display-name>

   <servlet>
      <servlet-name>FlightReservation</servlet-name>
      <servlet-class>com.springfrawework.web.servlet.DispatcherSevlet</servlet-class>
      <load-on-startup>1</load-on-startup>
   </servlet>

   <servlet-mapping>
      <servlet-name>FlightReservation</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

</web-app>

FlightReservation-servlet.xml

<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-3.0.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:component-scan base-package="com.practice.sfw.flight.reservation.controllers" />
    <mvc:annotation-driven />

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/</value>
        </property>
        <property name="suffix">
            <value>.html</value>
        </property>
    </bean>

</beans>

BasicController.java

package com.practice.sfw.flight.reservation.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/basic")
public class BasicController {

    @RequestMapping(method=RequestMethod.GET)
    public String getHello() {
        return "basic";
    }

}

basic.html

<html>
<body>
<h2>Hello from parallel universe</h2>
</body>
</html>

xml和html文件放在webapp / WEB-INF下

Maven构建和安装均成功。但是，当我访问 http://localhost:8080/FlightReservation/basic我得到一个The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

无法从控制器访问请求映射
