java忽略了单元测试的Jackon JsonProperty访问

Question

我在Spring Boot项目中使用Jackson进行序列化/反序列化

我有一个DTO对象，结构如下

public class TestDTO implements Serializable {
    private static final long serialVersionUID = 1L;

    private Long id;

    @JsonProperty(access = JsonProperty.Access.READ_ONLY)
    private UUID certificateId;

    @NotNull
    private Long orgId;

    @NotNull
    private CertificateType certificateType;

    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    @Valid
    @NotNull
    private PublicCertificateDTO publicCertificate;

    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    @Valid
    private PrivateCertificateDTO privateCertificate;

    @JsonProperty(access = JsonProperty.Access.READ_ONLY)
    private ZonedDateTime expiryDate;

    @JsonProperty(access = JsonProperty.Access.READ_ONLY)
    private ZonedDateTime createdDate;

    @JsonProperty(access = JsonProperty.Access.READ_ONLY)
    private ZonedDateTime updatedDate;
}

在我的单元测试中使用以下方法序列化此对象

public static byte[] convertObjectToJsonBytes(TestDTO object)
        throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);

    JavaTimeModule module = new JavaTimeModule();
    mapper.registerModule(module);

    return mapper.writeValueAsBytes(object);
}

导致具有WRITE_ONLY访问权限的字段被忽略（原因很明显）。因此，在序列化对象中，我看到publicCertificate和privateCertificate的空值

我确实试过设置mapper.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)

有没有其他方法可以忽略单元测试的这些属性
