spring学习历程
[url][/url] 1.基于Spring的注解测试.(@requestMapping)
老是报错：

我根本没有写过springServlet-servlet.xml这个配置文件。
web.xml也是配置正确的：
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
aplicationContext.xml也是配置正确的，加载就扫描需要映射的包：--正确应该修改为：springServlet-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>

----------------------------------
终于找到错误原因：
web.xml 中定义了一个名为 springServlet的 Spring MVC 模块，按照 Spring MVC 的契约，需要在 WEB-INF/springServlet-servlet.xml 配置文件中定义 Spring MVC 模块的具体配置。(参考地址：https://www.ibm.com/developerworks/cn/java/j-lo-spring25-mvc/)
