私はWebアプリ用のSpringFrameworkを試していますが、単純なhello worldMVCWebアプリでは動作しないようです。Spring 3.2、Tomcat 6（コンテキストは「/ spring」として設定）を使用します。注釈付きのControllerクラスが見つからない可能性がありますか？

私は打っていますhttp://localhost:8080/spring/hello

web.xml

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"

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



</web-app>

springapp-servlet.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    <bean

        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

私のコントローラー

package com.test.web;

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


@Controller
@RequestMapping("/hello")
public class HelloController {

    @RequestMapping(method = RequestMethod.GET)
    public String printHello(ModelMap model) {
        model.addAttribute("name", "Test");
        return "hello";
    }


}

Tomcat出力（springapp-servlet.xmlが見つかり、ロードされます）

注釈付きMVC構成を有効にしていません

<mvc:annotation-driven />

以下のコメントで判明したように、アプリケーションのクラスパスに問題がありました
