java正在试用Spring 3 MVC，出现页面错误

Question

试图配置spring 3 MVC，以下是我目前所做的：

我将所有spring 3.0库都添加到了我的netbeans项目中

我的网络。xml是：

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
    <servlet>
        <servlet-name>WebApplication1</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>WebApplication1</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>    
</web-app>

接下来，我创建了一个webapplication1servlet。xml，也在my/web inf文件夹中：

<?xml version="1.0" encoding="UTF-8"?>
<!--
 - DispatcherServlet application context for PetClinic's web tier.
-->
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
  xmlns:oxm="http://www.springframework.org/schema/oxm"
  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.xsd
    http://www.springframework.org/schema/oxm http://www.springframework.org/schema/oxm/spring-oxm-3.0.xsd">

 <!--
  - The controllers are autodetected POJOs labeled with the @Controller annotation.
 -->
 <context:component-scan base-package="org.springframework.Hi"/>

 <!--
  - The form-based controllers within this application provide @RequestMapping
  - annotations at the type level for path mapping URLs and @RequestMapping
  - at the method level for request type mappings (e.g., GET and POST).
  - In contrast, ClinicController - which is not form-based - provides
  - @RequestMapping only at the method level for path mapping URLs.
  -
  - DefaultAnnotationHandlerMapping is driven by these annotations and is
  - enabled by default with Java 5+.
 -->



 <!--
  - This bean resolves specific types of exceptions to corresponding logical
  - view names for error views. The default behaviour of DispatcherServlet
  - is to propagate all exceptions to the servlet container: this will happen
  - here with all other types of exceptions.
 -->
 <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
  <property name="exceptionMappings">
   <props>
    <prop key="org.springframework.web.servlet.PageNotFound">pageNotFound</prop>
    <prop key="org.springframework.dao.DataAccessException">dataAccessFailure</prop>
    <prop key="org.springframework.transaction.TransactionException">dataAccessFailure</prop>
   </props>
  </property>
 </bean>


 <!--
  - The BeanNameViewResolver is used to pick up the visits view name (below).
  - It has the order property set to 2, which means that this will
  - be the first view resolver to be used after the delegating content
  - negotiating view resolver.
  -->
 <bean class="org.springframework.web.servlet.view.BeanNameViewResolver" p:order="1"/>
 <!--

  - This bean configures the 'prefix' and 'suffix' properties of
  - InternalResourceViewResolver, which resolves logical view names
  - returned by Controllers. For example, a logical view name of "vets"
  - will be mapped to "/WEB-INF/jsp/vets.jsp".
 -->
 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/"
   p:suffix=".jsp" p:order="2"/>



</beans>

然后我创建了一个简单的欢迎。jsp位于/WEB-INF/jsp/welcome文件夹中。jsp

然后我创建了一个包：

组织。springframework。嗨

我创建了一个TestController。java文件：

包裹组织。springframework。嗨

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;


@Controller
public class TestController {


    @RequestMapping("/")
    public String welcomeHandler(){
        return "welcome";
    }

}

我想让它在没有任何文件扩展名的情况下工作，所以我不必用xxx来结束我的URL。htm等

因此，当我运行netbeans项目时，我得到了一个错误：

type Status report

message Servlet WebApplication1 is not available

description The requested resource (Servlet WebApplication1 is not

available) is not available.

我到底错过了什么

Tomcat日志

谢谢你的反馈

我的tomcat日志显示：
