Question

我正在关注this tutorial并遇到以下错误：

> Jul 19, 2013 2:18:14 PM
> org.springframework.web.servlet.DispatcherServlet noHandlerFound
> WARNING: No mapping found for HTTP request with URI
> [/Spring3MVC/hello.html] in DispatcherServlet with name 'spring'

我可以打开第一个jsp文件（index.jsp），但是当我点击“打招呼”时，它会向我显示404。我尝试了本教程的注释中建议的方法，但它们没有用。

我偏离教程的唯一地方是我使用Tomcat 7而不是6.其他所有使用Eclipse看起来都是一样的。我的代码与教程中的代码相同，因此无需立即将其粘贴到此处。：）

hello.jsp文件路径为：

Spring3MVC\WebContent\WEB-INF\jsp\hello.jsp

web.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"

    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>

spring-servlet.xml文件：

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

Controller.java

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.html")
    public ModelAndView helloWorld() {

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

（PS！也许你可以指点我的工作教程）

Answer 1

您的文件名为sprint-servlet.xml？也许这就是问题。

正如Sotirios Delimanolis指出的那样，默认情况下它应该以标签命名。

文件名应为spring-servlet.xml。

官方的Spring教程是here。
