@RestController
@RequestMapping(value="/api")
public class ProfissionalController {

    @Autowired
    ProfissionalRepository profissionalRespository;

    @GetMapping("/profissional")
    public List<Profissional> listaProfissional(){
        return profissionalRespository.findAll();
    }

    @GetMapping("/profissional/{id}")
    public Profissional idProfissional(@PathVariable(value="id") long id){
        return profissionalRespository.findById(id);
    }

    @PostMapping("/profissional/add")
    public Profissional addProfissional(@RequestBody Profissional profissional) {
        return profissionalRespository.save(profissional);
    }
}

Model

import java.io.Serializable;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import javax.validation.constraints.NotNull;


@Entity
@Table(name="TB_PROSSIONAL")
public class Profissional implements Serializable{

    /**

     */
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @NotNull
    private long id;
    @NotNull
    private String nome;
    private String endereco;
    private String telefone;
    private String telefone2;

    public long getId() {
        return id;
    }
    public void setId(long id) {
        this.id = id;
    }
    public String getNome() {
        return nome;
    }
    public void setNome(String nome) {
        this.nome = nome;
    }

Answer 1

I found the error, my controller, models and Repository folders were outside the main folder.
