  A:
  
  You should include spring-web.jar into your project:
   <dependency>
              <groupId>org.springframework</groupId>
              <artifactId>spring-web</artifactId>
              <version>3.2.3.RELEASE</version>
          </dependency>
  
  EDIT:
  I see you have Spring-web 3.0.x - try updating it to 3.2.x version :)
