所以基本上我试图在我的系统上运行一个基本的 Spring 3 MVC 示例。然而，这个例子很固执。我按照这里提到的步骤：http: //viralpatel.net/blogs/spring-3-mvc-create-hello-world-application-spring-3-mvc/

在我看来，映射明智。但是，当我在 Eclipse 或 Tomcat 服务器中直接在 Apache Tomcat 7.0 上运行它时，会出现以下错误：

**type** Status report

**message** /Spring3MVC/

**description** The requested resource is not available.

控制台日志如下所示：

我唯一能看到的是在Dec 5, 2012 1:13:04 PM提到的警告，但显然这不应该干扰应用程序。

我在 Web-INF/ 的 web.xml 如下：

<?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">
    <display-name>Spring3MVC</display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <servlet>
        <servlet-name>spring</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>
</web-app>

我在 Web-Inf/ 的 spring-servlet.xml 如下：

<?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:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    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="net.viralpatel.spring3.controller" />

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

我的 helloWorldController 如下：

package net.viralpatel.spring3.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {

    @RequestMapping("/hello")
    public ModelAndView helloWorld() {

        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message);
    }
}

最后我的 index.jsp 在 Web-INF/ 而我的 hello.jsp 在 Web-INF/jsp

我刚从 Spring 开始，但据我所知，这个应用程序应该运行。还比较了网上的其他例子，它们的结构相似。谷歌搜索错误只是说 servlet 的映射不存在，这是不正确的。希望有人在那里有解决方案。

提前致谢。

您已经在 web.xml 中定义了 *.html。因此，您需要使用 URL hello.html 访问它或将 url-pattern 更改为 / only。
