Javafx tableview 反射不起作用

我试图用模拟数据填充 JavaFx TableView 列，但我不断收到反射错误，即使我认为我正确遵循了 Bean 约定：

// Data model

class SensorTableEntry {
    SensorTableEntry(Integer id, String man, String type, String addr) {
        this.id = new SimpleIntegerProperty(id);
        this.manufacturer = new SimpleStringProperty(man);
        this.type = new SimpleStringProperty(type);
        this.btAddress = new SimpleStringProperty(addr);
    }

    private IntegerProperty id;
    public Integer getId() { return idProperty().get(); }
    public void setId(Integer value) { idProperty().set(value); }
    public IntegerProperty idProperty() { return id; } 

    private StringProperty manufacturer;
    public void setManufacturer(String value) { manufacturerProperty().set(value); }
    public String getManufacturer() { return manufacturerProperty().get(); }
    public StringProperty manufacturerProperty() { return manufacturer; }

    private StringProperty type;
    public void setType(String value) { typeProperty().set(value); }
    public String getType() { return typeProperty().get(); }
    public StringProperty typeProperty() { return type; } 

    private StringProperty btAddress;
    public void setBtAddress(String value) { btAddressProperty().set(value); }
    public String getBtAddress() { return btAddressProperty().get(); }
    public StringProperty btAddressProperty() { return btAddress; } 
}

// More code before this...


// Actual table inside the controller

ObservableList<SensorTableEntry> sensorEntries = FXCollections.observableArrayList(
    new SensorTableEntry(1, "manufacturer", "type", "00:00:00:00:00:00")
);   

TableView<SensorTableEntry> table = new TableView<SensorTableEntry>();

TableColumn<SensorTableEntry,Integer> idCol = new TableColumn<SensorTableEntry,Integer>("ID");
idCol.setCellValueFactory(new PropertyValueFactory<SensorTableEntry,Integer>("id"));

TableColumn<SensorTableEntry,String> manufacturerCol = new TableColumn<SensorTableEntry,String>("Manufacturer");
manufacturerCol.setCellValueFactory(new PropertyValueFactory<SensorTableEntry,String>("manufacturer"));

TableColumn<SensorTableEntry,String> typeCol = new TableColumn<SensorTableEntry,String>("Type");
typeCol.setCellValueFactory(new PropertyValueFactory<SensorTableEntry,String>("type"));

TableColumn<SensorTableEntry,String> btAddressCol = new TableColumn<SensorTableEntry,String>("Bluetooth Address");
btAddressCol.setCellValueFactory(new PropertyValueFactory<SensorTableEntry,String>("btAddress"));

table.setItems(sensorEntries);
table.getColumns().addAll(
    idCol,
    manufacturerCol,
    typeCol,
    btAddressCol
);

pane.getChildren().add(table); 

我检查了类似问题的其他答案，例如：

Javafx PropertyValueFactory 未填充 Tableview

JavaFx TableView 未填充所有必需的列

Javafx 表视图未显示所有列中的数据

但无论我怎么检查，我似乎都没有发现我的命名出了问题。我错过了什么吗？

我得到的例外是：

线程“JavaFX应用程序线程”中的异常java.lang.RuntimeException：java.lang.IllegalAccessException：类sun.reflect.misc.Trampoline无法使用修饰符“public”访问类SensorTableEntry的成员 在 com.sun.javafx.property.PropertyReference.getProperty(PropertyReference.java:200)

你的属性必须是完全可访问的，以便它们的 getter 和它们的所有者类两者都必须是公开的.

所以只需替换它：

class SensorTableEntry {

有了这个：

public class SensorTableEntry {
