在Spring MVC中在名稱為'dispatcher'的DispatcherServlet中找不到帶有URI的HTTP請求的映射...

Question

實際上，我已經配置了我的web.xml，pom.xml，disptcher-servlet.xml和控制器，但出現了這樣的錯誤：

"org.springframework.web.servlet.PageNotFound noHandlerFound
    WARNING: No mapping found for HTTP request with URI [/springwebstuck/] in DispatcherServlet with name 'dispatcher'".

我的很多人也問這個問題，但是他們的解決方案對我不起作用，我發布了一些配置文件：

web.xml

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
         http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1">
  <display-name>Archetype Created Web Application</display-name>
  <servlet>
  <servlet-name>dispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  </servlet>

  <servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

嘗試改變

<context:component-scan base-package="com.ashwin.springwebstuck.*"/>

至

<context:component-scan base-package="com.ashwin.springwebstuck"/>
