預設web.xml歡迎頁面為index.html

我給更改為：

1. <welcome-file-list>
2.     <welcome-file>/pages/template/login.jsp</welcome-file>
3. </welcome-file-list>

方法是，

welcome-file-list可以轉向到servlet，但是！！！前提是servlet不能有副檔名，否則就當成靜態檔案處理了

於是配置如下：

1. <welcome-file-list>
2.     <welcome-file>index</welcome-file>
3. </welcome-file-list>

1. <servlet>
2.         <servlet-name>springmvc</servlet-name>
3.         <servlet-class>org.springframework.web.servlet.DispatcherServlet
   </servlet-class>
4.         <init-param>
5.             <param-name>contextConfigLocation</param-name>
6.             <param-value>
7.                 /WEB-INF/classes/springmvc-config.xml  
8.             </param-value>
9.         </init-param>
10.         <load-on-startup>2</load-on-startup
    >
11.     </servlet>
12.     <servlet-mapping>
13.         <servlet-name>springmvc</servlet-name>
14.         <url-pattern>/index</url-pattern>
15.     </servlet-mapping>
