BeanCreationException

Referente ao curso Spring MVC I: Criando aplicações web, no capítulo Finalizando o carrinho e atividade Usando RestTemplate

Praticamente desde o começo do curso que meu projeto não funciona corretamente,
Já abri uns 2 tópicos aqui no fórum e nada, então agora na ultima aula 
do curso de spring mvc 1 decidi baixar o projeto completo do curso pra 
ver se funcionava, mas é isso o que aparece no meu console logo que rodo
o servidor:

SEVERE: Servlet.init() for servlet [SpringDispatcher] threw exception
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pagamentoController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: org.springframework.web.client.RestTemplate br.com.programingbooks.controller.PagamentoController.restTemplate; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.web.client.RestTemplate] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Só para comparação, o erro que da no projeto que eu escrevi é igual exceto pelo final,
enquanto que no projeto baixado aparece isso:

WARNING: The web application [programingbooks] registered the JDBC driver [com.mysql.cj.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

no meu aparece isso:

Oi Murilo, tudo bem?

Posta aqui sua classe PagamentoController e pom.xml, por favor.

Uma pergunta, quais versões do JDK e do Tomcat você está utilizando para subir esse projeto?

Olá Otávio,

@Controller
@RequestMapping("/pagamento")
public class PaymentController {

    @Autowired
    private PurchaseCart pcart;
    @Autowired(required = true)
    private RestTemplate rt;

    @RequestMapping(value="/finalizar", method=RequestMethod.POST)
    public Callable<ModelAndView> finish(RedirectAttributes model) {
        return () -> {
            String uri = "http://book-payment.herokuapp.com/payment";

            try {
                String response = rt.postForObject(uri, new PaymentDatas(pcart.getTotal()),
                    String.class);
                System.out.println(response);
                model.addFlashAttribute("success", response);
                return new ModelAndView("redirect:/produtos/listar");
            } catch(HttpClientErrorException exception) {
                exception.printStackTrace();
                model.addFlashAttribute("fail", "Value oversize the permitted");
                return new ModelAndView("redirect:/produtos/listar");
            }
        };
    }
}

Depois que eu li a exceção eu mudei a anotação @Autowired
para ver se adiantava alguma coisa, infelizmente não.

No começo do curso o professor usa o jboss para criar
o projeto, como eu não consegui eu criei um projeto maven
direto pelo eclipse

Meu tomcat é o da verção 9.0.24 e minha jdk é a 12, mas também tenho a 8 no meu computador.

outra coisa que mudei no pom é o mysql já que eu tenho a versão 8.0.18 istalada no meu pc,
eu também já fiz um teste e alterei as versões de todos as dependências para as atuais
só pra ver no que dava, e deu erro, ai voltei para como estava antes.
solução!

Estou achando que é alguma incompatibilidade entre essas versões. Tenta subir utilizando JDK 8 no Tomcat 7, se der algum erro posta aqui, por favor.
