Could you tell me why this error occurs?

Answer 1

org.springframework.web.servlet is a part of Spring MVC, it's located in org.springframework:spring-webmvc artifact:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
org.springframework:spring-web contains common functionality for using Spring in web applications, it's not tied to Spring MVC.

Answer 2

add this dependency to your pom.xml
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
