我正在开发一个API（只是为了学习），当我尝试使用端点列出保存在我的DB（本地）上的文件时，我收到了这个：

[
{
    "nome": null,
    "url": null,
    "type": null,
    "size": 0,
    "paciente": null,
    "medico": null
}

字符串
]
这是我的终点：

@GetMapping("/files")
    public ResponseEntity<List<ResponseFile>> getListFiles() {
        List<ResponseFile> files = resultadosExamesService.listarTodosArquivos().map(dbFile -> {
            String fileDownloadUri = ServletUriComponentsBuilder
                    .fromCurrentContextPath()
                    .path("/exames/files/")
                    .path(dbFile.getIdExame().toString())
                    .toUriString();

            return new ResponseFile(
                    dbFile.getNomeArquivo(),
                    fileDownloadUri,
                    dbFile.getTipoExame(),
                    dbFile.getArquivoExame().length);
        }).collect(Collectors.toList());

        return ResponseEntity.status(HttpStatus.OK).body(files);
    }

我的ResponseFile：

public class ResponseFile {
    private String nome;
    private String url;
    private String type;
    private long size;
    private Paciente paciente;

    private PacientesDTO pacienteDTO;
    private Medico medico;

    public ResponseFile(String nomeArquivo, String fileDownloadUri, String tipoExame, int length) {
        this.nome = nome;
        this.url = url;
        this.type = type;
        this.size = size;

    }
//get and set...

我期待收到这样的JSON：（这个端点列出了来自DB的医生预约）

[
{
    "idConsulta": 2,
    "nomeMedico": "Camila Bernardo",
    "nomePaciente": "João",
    "motivoConsulta": "fortes dores de cabeça",
    "dataConsulta": "2023-12-12T14:00:00"
},
{
    "idConsulta": 3,
    "nomeMedico": "Camila Bernardo",
    "nomePaciente": "João",
    "motivoConsulta": "fortes dores de cabeça",
    "dataConsulta": "2023-12-12T16:00:00"
}
