Answer 1

确保满足所有要求，尤其是 “的Servlet容器3.0+”。此外，还要确保您的web.xml文件以及配置了Servlet 3.0 API：

<web-app xmlns="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" 
     version="3.0"> 
... 
</web-app>

我需要以下添加到mvc-core-config.xml为了揭露蒲公英的资源：

<mvc:resources mapping="/dandelion/**" location="classpath:/META-INF/resources/dandelion/" />
