模块javafx.base无法访问类application.Customer（在模块FCR中），因为模块FCR没有向javafx.base打开应用程序

Question

原因：java.lang.IllegalAccessException：模块javafx.base无法访问类application.Customer（在模块FCR中），因为模块FCR没有向javafx.base打开应用程序

在javafx.base/com.sun.javafx.property.methodHelper.invoke(MethodHelper.java:69)

这是客户的代码：

public class customer {

private final IntegerProperty ID;
private final StringProperty  firstName;
private final StringProperty  lastName;
private final StringProperty  carPlate;
private final IntegerProperty telephoneNum;

public customer(int ID,String firstName, String lastName, String carPlate, int telephoneNum) {
    this.ID = new SimpleIntegerProperty();
    this.firstName = new SimpleStringProperty();
    this.lastName = new SimpleStringProperty();
    this.carPlate = new SimpleStringProperty();
    this.telephoneNum = new SimpleIntegerProperty();

    setID(ID);
    setfirstName(firstName);
    setlastName(lastName);
    setcarPlate(carPlate);
    settelephoneNum(telephoneNum);
}

public final StringProperty firstNameProperty() {
    return firstName;
}

public final String getfirstName() {
    return firstName.get();
}

public final void setfirstName(String fname) {
    firstName.set(fname);
}

public final IntegerProperty IDProperty() {
    return ID;
}

public final int getID() {
    return ID.get();
}

public final void setID(int iD) {
    ID.set(iD);
}

public final StringProperty lastNameProperty() {
    return lastName;
}

public final String getlastName() {
    return lastName.get();
}

public final void setlastName(String lname) {
    lastName.set(getfirstName());;
}

public final IntegerProperty telephoneNumProperty() {
    return telephoneNum;
}

public final int gettelephoneNum() {
    return telephoneNum.get();
}

public final void settelephoneNum(int tnum) {
    telephoneNum.set(tnum);;
}

public final StringProperty carPlateProperty() {
    return carPlate;
}

public final String getcarPlate() {
    return carPlate.get();
}

public final void setcarPlate(String platenum) {
    carPlate.set(platenum);
}

public class checkCustomers {

private customersData q = Main.q;

@FXML
private TableView table;


@FXML
private TableColumn firstName;
@FXML
private TableColumn lastName;
@FXML
private TableColumn carPlate;
@FXML
private TableColumn telephoneNumber;


@FXML
public void initialize() {
    
System.out.println(1);

firstName.setCellValueFactory(new PropertyValueFactory<customer, String>("firstName"));
lastName.setCellValueFactory(new PropertyValueFactory<customer, String>("lastName"));
carPlate.setCellValueFactory(new PropertyValueFactory<customer, String>("carPlate"));
telephoneNumber.setCellValueFactory(new PropertyValueFactory<customer, Integer>("telephoneNumber"));
table.setItems(FXCollections.observableArrayList(q.getAllCustomers()));
}

module-info.java代码如下：

module FCR {
    requires javafx.controls;
    requires javafx.fxml;
    requires java.sql;
    requires javafx.base;

    opens application to javafx.graphics, javafx.fxml;
}

我想我应该在模块中添加一些信息-有人能帮忙吗？

Answer 1

PropertyValueFactory类使用反射获取命名属性。您必须授权该类的模块(javafx.base)对您的代码进行必要的访问，以便该反射能够工作。

变化：

opens application to javafx.graphics, javafx.fxml;

致：

opens application to javafx.graphics, javafx.fxml, javafx.base;

null

null

lastNameCol.setCellValueFactory(data -> data.getValue().lastNameProperty());
