RequestMapping cannot be resolved to a type

I'm just starting to study Spring Boot. I installed STS and created an application with Web + JPA + MySQL + DevTools + Security. When I'm creating my Controller and I note it with @RequestMapping, STS says RequestMapping can not be resolved to a type.

import org.springframework.stereotype.Controller;

@Controller
public class TestController {

    @RequestMapping("/test")    
    public String test() {
        return "test";
    }

}

EDIT

My pom.xml

<?xml version="1.0" encoding="UTF-8"?>

How do I solve this?

**You should add RequestMethodType as like GET/ POST/ PUT/ DELETE.**Here we use get method for return something

@Controller
public class TestController {
    @RequestMapping(value="/test",method=RequestMethod.GET)    
    public String test() {
        return "test";
    }
}

Check the POM and do a maven update. make sure you have imported

import org.springframework.web.bind.annotation.RequestMapping;
