No mapping found for HTTP request with URI

spring-mvc.xml 文件没有注入controller类

<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->

<context:component-scan base-package="com.rinlink.intelligent.controller" />

添加这么一段过滤，又出现No mapping found for HTTP request with URI

<mvc:resources location="/" mapping="/**/*.html" />
<mvc:resources location="/" mapping="/**/*.js" />
<mvc:resources location="/" mapping="/**/*.css" />
<mvc:resources location="/" mapping="/**/*.png" />
<mvc:resources location="/" mapping="/**/*.gif" />
<mvc:resources location="/" mapping="/**/*.ttf" />
<mvc:resources location="/" mapping="/**/*.woff" />
<mvc:resources location="/" mapping="/**/*.woff2" />

解决办法就是：

添加一行

<mvc:annotation-driven />
