前两篇文章介绍404问题，但是本质原因还是没有给出来，此时也不能给出答案，很是抱歉，但是这个问题我会一直跟踪。哪天知道本质原因，我会及时更新博客。
这篇文章接着分析[Servletname]-servlet.xml为什么需要放置src下面：
有的博客上的一般也可以将[Servletname]-servlet.xml文件放置在webcontent下面：
但是爆出：

是不是我们在web.xml中配置了
<init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:HelloWeb-servlet.xml</param-value> </init-param>本来spring默认配置的xml就是[servletname]-servlet.xml去掉试试呢？
web.xml文件：
<web-app id="WebApp_ID" 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"> <display-name>Spring MVC Application</display-name> <servlet> <servlet-name>HelloWeb</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>HelloWeb</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>Test</welcome-file> </welcome-file-list> </web-app>爆出init fail 500错误。

是不是[servletname]-servlet.xml 需要和 web.xml同一级放在WEB-INF文件夹下面呢？？？？
可以的！！！终于证明了[servletname]-servlet.xml 使用默认条件下必须将其和web.xml放在同一目录下！
那么此条件下是不是可以不配置首页面呢？？？
还是不行呀！！！！ 默认首页看样子是必须要添加的！！！
