與Spring-webmvc映射問題

Question

在建立一個Spring應用程序（打包爲一個WAR和託管通過Tomcat的），我得到一個404和下面的錯誤，當我嘗試訪問「本地主機：8080」：

4479 [http-bio-8080-exec-1] WARN org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/WEB-INF/pages/index.html] in DispatcherServlet with name 'spring' 

絕對有一個/WEB-INF/pages/index.html文件。

這裏是我的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

    <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>/*</url-pattern> 
    </servlet-mapping> 

</web-app> 

此外，這裏是我的春天-servlet.xml文件：

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

    <context:component-scan base-package="com.company.app.controller" /> 

    <mvc:annotation-driven /> 

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

</beans> 

而且從我的控制器GET方法：

package com.company.app.controller; 

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

@Controller 
public class SplashController { 

    @RequestMapping(value="/", method=RequestMethod.GET) 
    public String index() { 
     return "index"; 
    } 

} 

那麼，我的配置有什麼問題？

另外：我想包括Spring的初始設置我的控制檯輸出，也許它會提供一個或兩個線索，缺什麼：

0 [localhost-startStop-1] INFO org.springframework.web.context.ContextLoader - Root WebApplicationContext: initialization started 
92 [localhost-startStop-1] INFO org.springframework.web.context.support.XmlWebApplicationContext - Refreshing Root WebApplicationContext: startup date [Sun Jan 26 16:16:57 EST 2014]; root of context hierarchy

Answer 1

我使用Spring 3.2.3版本。試試這個配置：

正確的web.xml文件：

<servlet-mapping> 
<servlet-name>Spring</servlet-name> 
<url-pattern>*.html</url-pattern> 
</servlet-mapping> 

更正爲spring-servlet.xml：

<context:component-scan base-package="your.package.controller"/> 
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> 
<bean id="internalViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" 
     p:viewClass="org.springframework.web.servlet.view.JstlView" 
     p:prefix="/WEB-INF/jsp/" 
     p:suffix=".jsp"/> 
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver"/> 

正確的映射annotacion：

@RequestMapping(value="/index", method=RequestMethod.GET) 

，創造的index.jsp文件。

Answer 2

無論出於何種原因，改變了我的web.xml這個的Servlet映射部分解決了這個問題：

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

Answer 3

我也面臨同樣的問題時，我的一個朋友建議我檢查包宣言。
當我知道哪個包的控制器請求映射和上下文的定義：component-scan base-package來檢查我看到它是不一樣的，並且在給它正確的包名後它開始工作。

檢查在Spring配置文件

<context:component-scan base-package="your package name" >
