[Java知识库]spring mvc开发javaweb遇到${pageContext.request.contextPath}不生效的问题

我的问题是版本太低导致的

之前的springmvc-servlet.xml

?

修改版本后

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-config/springmvc-servlet.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
