Conversion error when sending input to controller to save

Question

Good evening guys, I’m having trouble solving this problem, I hope you can help me... When trying to save data from View only one field returns this error:

Failed to Convert Property value of type java.lang.String to required type com.sisdcon.oficinas.model.Usuarios for Property corretor_heados; nested Exception is java.lang.Illegalstateexception: Cannot Convert value of type java.lang.String to required type com.sisdcon.oficinas.model.Usuarios for Property corretor_heados: no matching Editors or Conversion Strategy found

on the screen has 3 more fields of the same type and works correctly, below I leave the Model, Controller (save method) and the view snippet (containing the fields)

Model....

 @Table(name = "heados")
@Entity
public class Atendimentos {
   @Id
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   private Long id_heados;

   @ManyToOne(fetch = FetchType.EAGER)
   @JoinColumn(name = "cadastro_heados", referencedColumnName = "id_cadastros", updatable = false, insertable = false)
   @NotNull(message = "Cliente Obrigatório.")
   private Cadastros cadastro_heados;

   @ManyToOne(fetch = FetchType.EAGER)
   @JoinColumn(name = "veiculo_heados", referencedColumnName = "id_veiculos", updatable = false, insertable = false)
   @NotNull(message = "Veículo Obrigatório.")
   private Veiculos veiculo_heados;

   @ManyToOne(fetch = FetchType.EAGER)
   @JoinColumn(name = "seguradora_heados", referencedColumnName = "id_cadastros", updatable = false, insertable = false)
   private Cadastros seguradora_heados;

   ?//--- ESTE É O CAMPO QUE OCORRE O ERRO!!!
   @ManyToOne( fetch = FetchType.EAGER)
   @JoinColumn(name = "corretor_heados", referencedColumnName = "id_usuarios", updatable = false, insertable = false)
   private Usuarios corretor_heados;


   private Long usuario_heados;
   private String veiculo_km_heados;

Controller... saving method

@RequestMapping(method = RequestMethod.POST)
   public String salvar(@Validated Atendimentos atendimentos, Errors errors, RedirectAttributes attributes) {

      System.out.println("vou tentar salvar");

      ///-- O SISTEMA ENTRA AQUI RETORNANDO O ERRO
      if (errors.hasErrors()) { 
         System.out.println("parei no erro!");
         return CADASTROVIEW;
      }
      try {

         atendimentosService.salvar(atendimentos);

      } catch (IllegalArgumentException e) {
         return CADASTROVIEW;
      }

      return "redirect:/atendimentos/"+atendimentos.getId_heados();
   }

View section contento os campo

<form id="FormAtendimentos" method="POST" th:action="@{/atendimentos}" th:object="${atendimentos}">

   <input type="text" th:field="*{seguradora_heados}">

   <input type="text" th:field="*{veiculo_heados}">

    <!--  ESSE É O CAMPO QUE O SISTEMA RETORNA O ERRO    -->
   <input type="text" th:field="*{corretor_heados}"> 


</form>

I realized that, only when filling in the case of Editing, it does not fill with the table ID "a number" it fills with the reference to the model in this way...

com.sisdcon.oficinas.model.Usuarios@22120bd8

another thing is in the query that JPA assembles, in it I have several joins, hence it even time uses Ner Join or left Uter Join.... below I leave the query mounted by JPA....

I was able to solve only now, and what happened is that it is mandatory have a Repository even if empty, I only created when I wanted to do a manual search, ie, create a custom query, after I created Repository even if empty, funfou!!! When you go through the same trouble, try this!! Thanks!!!
