Tomcat给我以下严重错误。

我的dispatcher-servlet.xml文件包含处理程序的Bean
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>
然后在我的web.xml文件中引用哪个：
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>
</servlet>
我的项目正在使用1.8源/二进制格式。该项目将运行并出现此错误，这让我有点发疯，我担心这可能会导致我没有看到的问题。
答案 0 :(得分：1)
Spring 5.1.2没有此类。
