用spring mvc模式写了一段代码，但一直都会提示404，不知道错误在哪，求指点。

Question

用springmvc 和spring jdbc谢了一段代码，但一直提示404错误，不知道该如何解决，已经困扰很多天了。（Dao中只写了增加，没有写service，只是想试一下能不能连接到数据库，customer只有id和name）
web.xml文件内容如下：

 <?xml version="1.0" encoding="UTF-8"?>
<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">

jdbc.properties文件：

jdbc.url = jdbc:oracle:thin:@localhost:1521:WAREHOUSE
jdbc.username = sys as SYSDBA
jdbc.password = oracle123

错误提示：

我已经把CustomerMVC-servlet的controller改成了Controller，但是还是会出现404，但是不会抛出异常。会出现最后一张图的提示。

Web.xml 里面的 CustomerMVC 改成springmvc 试一下
