IDEA使用SpringSecurity整合SSM，报错No WebApplicationContext found: no ContextLoaderListener or DispatcherServlet registered?

Question

在SSM中使用了SpringSecurity之后，启动tomcat弹出的页面就会出现报错，开发环境和报错信息如下：

开发的环境 : IDEA
错误提示：java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener or DispatcherServlet registered?
页面报错信息：

导入的依赖

<!-- SpringSecurity 对 Web 应用进行权限管理 -->
            <dependency>
                <groupId>org.springframework.security</groupId>
                <artifactId>spring-security-web</artifactId>
                <version>${security-version}</version>
            </dependency>
            <!-- SpringSecurity 配置 -->
            <dependency>
                <groupId>org.springframework.security</groupId>
                <artifactId>spring-security-config</artifactId>
                <version>${security-version}</version>
            </dependency>
            <!-- SpringSecurity 标签库 -->
            <dependency>
                <groupId>org.springframework.security</groupId>
                <artifactId>spring-security-taglibs</artifactId>
                <version>${security-version}</version>
            </dependency>

配置SpringSecurity的web.xml

    <!--配置springsecurity的DelegatingFilterProxy-->
    <filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

创建的注册类

package com.atguigu.crowd.mvc.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
@EnableWebSecurity
public class WebAppSecurityConfig extends WebSecurityConfigurerAdapter {

}

在没有对配置类进行具体配置之前就出现了问题。我自己经过测试，在只对web.xml进行配置之后启动tomcat就出现了如上的问题，请求大家帮帮我，在百度搜来的都是千篇一律的。根本没有实际的作用。谢谢大家！！！
