You can’t import org.springframework.web.servlet.DispatcherServlet in a java file. This class is mainly under the spring-webmvc jar package. All imported jar packages are as follows:

Right-click the project–>properties–>Deployment Assembly–>add–>Java Build Path Entries–>import all dependent Jar packages and restart tomcat.
