springmvc No mapping found for HTTP request

spring mvc 出现No mapping found for HTTP request with URI /css/main.css in DispatcherServlet with name ‘springmvc’错误解决

方法1

在web.xml文件上配置

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>

方法2

在spring-mvc配置文件中配置

# 先在spring-mvc配置文件中声明spring-mvc标签
<beans xmlns="http://www.springframework.org/schema/beans"
   ...
   xmlns:mvc="http://www.springframework.org/schema/mvc"
   xsi:schemaLocation="...
   http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
   ">
# 再添加
<mvc:default-servlet-handler/>
# 或者
<mvc:resources mapping="/**" location="/" />
