遇到这个问题的有很多种情况

第一种：web.xml问题，这个只要好好检查一下代码就可以解决

 <!-- 监听加载Spring -->
    <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:applicationContext*.xml</param-value>
    </context-param>
    <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 编码过滤器 -->
      <filter>
        <filter-name>Encoding</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <!-- <async-supported>true</async-supported> -->
        
        <init-param>
            <param-name>encoding</param-name>
            <param-value>utf-8</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>Encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>  
  
  <!-- 配置spring mvc前端控制器 -->
  <servlet>
      <servlet-name>springwebmvc</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
           <!-- 通过此参数的配置加载spring配置文件，然后初始化资源 -->
           <param-name>contextConfigLocation</param-name>
           <param-value>classpath:spring-*.xml</param-value>
           <!-- <param-value>classpath:spring-*.xml</param-value> -->
      </init-param>
      <!--让tomcat启动则加载此servlet对象，数值越小优先级越高 -->
      <load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 配置Spring MVC前端控制器映射(servlet映射) -->
  <servlet-mapping>
       <servlet-name>springwebmvc</servlet-name>
       <url-pattern>/</url-pattern><!-- 除jsp拦截所有 -->
  </servlet-mapping>
  
  
  <!-- <welcome-file-list>
    <welcome-file>admin/index.jsp</welcome-file>
  </welcome-file-list> -->

网上大部分都是这个的问题

servlet-mapping中的

<url-pattern>/</url-pattern>

第二种：maven仓库下有的jar包下载不完全的问题

错误信息中，我挑选重要的一段，我在项目中需要的也是这个问题，最后在不懈的努力下解决了，特写下这篇博客为后来遇到错误的人！

出现这类问题首先我们查看哪些包没下载完全

第一步：再pom.xml文件右键run as选择Maven test看是否报错，从报错信息中看缺失的包，如果没有报错，则进入第二步

第二步：在pom.xml文件下右键，run as选择maven build，再Goals下输入以下命令:clean install -U

 

 运行，会有很多报错信息，在这些错误信息中找到缺失的包，只需要找到对应的目录，之后删掉那个文件夹，最后右键项目重新下载jar包

 

 

就可以更新maven的依赖包重新下载！下载好运行即可！
