我正在嘗試使用 Room 將 base64 值保存到我的 sqlite 數據庫中，但由于某種原因它沒有保存。好吧，我假設它沒有保存，因為當我嘗試讀取具有base64列的表時，它會返回除base64列之外的所有其他列的值。我做錯了什么？我的實體：@Entity(tableName = "healthCareWorkerInformation",        foreignKeys = @ForeignKey(                entity = HealthCareWorker.class,                parentColumns = {"id"},                childColumns = {"hcwId"},                onDelete = ForeignKey.CASCADE),        indices = @Index(                value = {"hcwId"}))public class HealthCareWorkersInformation {    @PrimaryKey(autoGenerate = true)    @ColumnInfo(name = "hcwInfoId")    private long id;    private long hcwId;    //@ColumnInfo(typeAffinity = ColumnInfo.BLOB)    private String base64Image;    private String updatedAt = new SimpleDateFormat("dd MM yyyy, HH:mm",            Locale.getDefault()).format(Calendar.getInstance().getTime());    public HealthCareWorkersInformation() {    }    @Ignore    public HealthCareWorkersInformation(long hcwId) {        this.hcwId = hcwId;    }    public long getId() {        return id;    }    public void setId(long id) {        this.id = id;    }    public long getHcwId() {        return hcwId;    }    public void setHcwId(long hcwId) {        this.hcwId = hcwId;    }    public String getBase64Image() {        return base64Image;    }    public void setBase64Image(String base64Image) {        this.base64Image = base64Image;    }    public String getUpdatedAt() {        return updatedAt;    }    public void setUpdatedAt(String updatedAt) {        this.updatedAt = updatedAt;    }}我的道：@Insertvoid insertHealthCareWorkerInformation(HealthCareWorkersInformation healthCareWorkersInformation);@Query("SELECT * FROM HEALTHCAREWORKERINFORMATION")LiveData<List<HealthCareWorkerInformation>> getHCWInfo();我發送的示例數據：除 base64 列外，其他所有內容都將保存。請協助。
