Java 使用IntelliJ IDEA的Spring MVC配置

我想使用Spring MVC framework创建一个web应用程序，因此我遵循以下步骤：

我下载spring-framework-5.1.2.RELEASE-dist

我使用IntelliJ IDEA打开了一个新项目（Web应用程序）

我在WEB-INF下创建了一个lib目录，并添加了以前下载的所有JAR文件

我在WEB-INF下为所有JSP视图创建了一个视图目录

我添加了两个XML文件：web.XML和spring-demo-servlet.XML

web.xml

<?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_3_1.xsd"
     version="3.1">

<display-name>spring-mvc-demo</display-name>

<!-- Spring MVC Configs -->

<!-- Step 1: Configure Spring MVC Dispatcher Servlet -->

    <servlet-name>dispatcher</servlet-name>

    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Step 2: Set up URL mapping for Spring MVC Dispatcher Servlet -->
<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

当我使用GlassFish服务器运行应用程序时，出现以下异常：
