Não consigo fazer o projeto subir

Olá.

Gerei um projeto no link: https://start.spring.io/

Importei na IDE e nenhum erro aparece ao executar... Instalei o tomcat também, consigo executá-lo sem erros.

Mas quando tento acessar localhost:8080, abre a página do tomcat, não o conteúdo da minha classe. Tentei colocar outra coisa no @RequestMapping, mas ao acessar aquele endereço recebo um erro 404.

Minha classe:

package com.teste.teste;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@SpringBootApplication
@Controller
public class TesteApplication {

    @RequestMapping("/teste")
    @ResponseBody
    public String ola() {
        return "teste";
    }

    public static void main(String[] args) {
        SpringApplication.run(TesteApplication.class, args);
    }
}
