Question

如果需要，你真的需要做一个完整的阅读，这样你才能真正理解我的问题。我会非常感激和感激。我明白了：

java.io.FileNotFoundException: photo.png (The system cannot find the file specified)
at java.io.FileInputStream.open0(Native Method)
at java.io.FileInputStream.open(FileInputStream.java:195)
at java.io.FileInputStream.<init>(FileInputStream.java:138)
at com.nationalid.NationalIDModel.getPicture(NationalIDModel.java:150)
at com.nationalid.NationalViewController.goToPrint(NationalViewController.java:560)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

当我运行我的应用时。

这一行：

at com.nationalid.NationalIDModel.getPicture(NationalIDModel.java:150)

对应于此代码的第6行：

public FileInputStream getPicture(PreparedStatement preparedStatement)
{
    File file = new File("photo.png");
    FileInputStream fileInputStream;
    try {
        fileInputStream = new FileInputStream(file);
        preparedStatement.setBinaryStream(7, (InputStream) fileInputStream, (int) file.length());
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return (FileInputStream) Picture.getBean();
}

这一个：

at com.nationalid.NationalViewController.goToPrint(NationalViewController.java:560)

对应于我在索引7处设置binaryStream的行（图像文件）：

public void goToPrint(ActionEvent event) {
    myConnection = SqliteConnection.connector();

    try {
        NationalIDModel national = (NationalIDModel)nationalTable.getSelectionModel().getSelectedItem();
        String query = "SELECT * FROM nationalid_table " + "WHERE unique_number = ? AND passportID = ? AND firstname = ?" + "AND lastname = ? AND issuedate = ? AND expirydate = ? AND " + "picture = ?

        preparedStatement = myConnection.prepareStatement(query);
        preparedStatement.setString(1, national.getUniqueNumber());
        preparedStatement.setString(2, national.getPassportID());
        preparedStatement.setString(3, national.getFirstname());

        preparedStatement.setString(14, national.getIDNumber());
        preparedStatement.setString(15, national.getAge());
        myResultSet = preparedStatement.executeQuery();

        if (myResultSet.next())
        {
            //((Node)event.getSource()).getScene().getWindow().hide();
            Stage window = new Stage();
            FXMLLoader loader = new FXMLLoader();
            Pane root = loader.load(getClass().getResource("../nationalid/PersonsDetailsView.fxml").openStream());

            PersonsDetailsController personsDetailsController = (PersonsDetailsController) loader.getController();
            personsDetailsController.getUsers(
                    (FileInputStream) national.getPicture(preparedStatement),
                    national.getFirstname(),
                    national.getLastname(),
                    national.getGender(),
                    national.getHeight(),
                    national.getDateOfBirth(),
                    national.getNationality(),
                    national.getAddress(),
                    national.getIDNumber(),
                    national.getIssueDate(),
                    national.getExpiryDate()
                    );

            Scene scene = new Scene(root);
            window.setTitle("Hello " + txtfirstname.getText() + ", this is your menu page");
            window.getIcons().add(new Image("file:users.png"));
            window.setScene(scene);
            window.show();
            NotificationType type = NotificationType.SUCCESS;
            TrayNotification trayNotification = new TrayNotification();
            trayNotification.setTitle("User Details");
            trayNotification.setMessage("User Details Displayed!");
            trayNotification.setNotificationType(type);
            trayNotification.showAndDismiss(Duration.seconds(4));
        }

        preparedStatement.close();
    } catch (SQLException ep) {
        //Logger.getLogger(AddUserController.class.getName()).log(SEVERE, null, ep);
        System.out.println(ep);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

但首先这是我问题的背景：

我正在使用智能创意中的javafx构建桌面应用程序。我正在使用MVC模式。我已经构建了一个模块：显示所有可能的数据操作，包括统计估计和数据库值的表示。

现在我正在构建第二个模块：National Identification将从Birth表中提取数据，进行可能的操作并将其存储在ID表中。该项目的目的实际上是获得每个人的真实跟踪......

现在在出生模块中，我有一个查看和打印按钮的视图和打印按钮，所以我必须从数据库中提取数据。每个窗口都是一个fxml文件，其中包含与之关联的特定控制器。

在目前的模块（识别）中，我想做同样的事情，但这次我也必须从数据库中提取图像。

所以我能够提取所有信息并在imageview中正确显示个人图像。

现在在我的ID模块包中，我有一个数据库操作模型：

package com.nationalid;    
public class NationalIDModel {

private final SimpleStringProperty UniqueNumber;
private final SimpleStringProperty PassportID;
private final SimpleStringProperty Firstname;
private final SimpleStringProperty Lastname;
private final SimpleStringProperty IssueDate;
private final SimpleStringProperty ExpiryDate;
private final SimpleStringProperty Picture;
private final SimpleStringProperty Nationality;
private final SimpleStringProperty DateOfBirth;
private final SimpleStringProperty Gender;
private final SimpleStringProperty Address;
private final SimpleStringProperty Height;
private final SimpleStringProperty BirthID;
private final SimpleStringProperty IDNumber;
private final SimpleStringProperty NumberOfID;

public NationalIDModel(String unique_number,
                       String passportID,

    this.Status = new SimpleStringProperty(status);
}

public String getUniqueNumber() {
    return UniqueNumber.get();
}

    return UniqueNumber;
}

public void setUniqueNumber(String uniqueNumber) {
    this.UniqueNumber.set(uniqueNumber);
}

}

public SimpleStringProperty passportIDProperty() {

public void setLastname(String lastname) {
    this.Lastname.set(lastname);
}

public String getIssueDate() {
    return IssueDate.get();

}

public String getIDNumber() {
    return IDNumber.get();
}

    return Age;
}

public void setAge(String age) {
    this.Age.set(age);
}

public String getStatus() {
    return Status.get();
}

public SimpleStringProperty statusProperty() {
    return Status;
}

public void setStatus(String status) {
    this.Status.set(status);
}

}

我故意尝试从此修改getPicture（）方法：

public String getPicture() {
    return Picture.get();
}

到此：

public FileInputStream getPicture(PreparedStatement preparedStatement)
{
    File file = new File("photo.png");
    FileInputStream fileInputStream;
    try {
        fileInputStream = new FileInputStream(file);
        preparedStatement.setBinaryStream(7, (InputStream) fileInputStream, (int) file.length());
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (SQLException e) {
        e.printStackTrace();
    }
    return (FileInputStream) Picture.getBean();
}

以便它可以匹配：

preparedStatement.setBinaryStream(7, national.getPicture(preparedStatement));

            txtNumberOfIDCard.setText(myResultSet.getString("number_of_id"));
            txtage.setText(myResultSet.getString("age"));
            statuslbl.setText(myResultSet.getString("status"));
        }
        //goToPrint();
        preparedStatement.close();
        myResultSet.close();
    }
    catch (SQLException ex)
    {
        System.out.println(ex);
        Logger.getLogger(NationalViewController.class.getName()).log(Level.SEVERE, null, ex);
    }
}

}

应该带我到这个界面PersonsDetailsController：

package com.nationalid;



public class PersonsDetailsController implements Initializable{



@Override
public void initialize(URL location, ResourceBundle resources) {

}

public void getUsers(FileInputStream inputeStream, String userinfo1, String userinfo2,
                     String userinfo3, String userinfo4,
                     String userinfo5, String userinfo6,
                     String userinfo7, String userinfo8,
                     String userinfo9, String userinfo10)
{
    userlabel.setText("View " + userinfo2 + "'s" + " Details");

    try (OutputStream outputStream = new FileOutputStream(new File("photo.jpg"))) {
        byte[] content = new byte[1024];
        int size;
        while((size = inputeStream.read(content)) != -1)
        {
            outputStream.write(content, 0, size);
        }
        outputStream.close();
        inputeStream.close();

        Image image = new Image("file:photo.jpg", 247, 232, true, true);
        imageViewCapture.setImage(image);
    } catch (IOException e) {
        e.printStackTrace();
    }

    txtfirstname.setText(userinfo1);
    txtlastname.setText(userinfo2);
    txtgender.setText(userinfo3);
    txtheight.setText(userinfo4);
    txtdateofbirth.setText(userinfo5);
    txtnationality.setText(userinfo6);
    txtaddress.setText(userinfo7);
    txtidnumber.setText(userinfo8);
    txtissuedate.setText(userinfo9);
    txtexpirydate.setText(userinfo10);
}
}

我可以打印。

我的目标是将图像从NationalViewController传递到我可以打印的PersonsDetailsController。

我已成功将图像从数据库拉到NationalViewController，方法为pullIDDataOnclick（），并将其显示在imageview中。

但是每当我点击查看按钮转到PersonsDetailsController界面时，我都会提到错误。

请帮忙！感谢。

如何传递从数据库中提取的图像文件并放入页面，从javafx中的一个页面到另一个页面
