使用javafx ListProperty

Question

如何使用javafx listproperty在jpa实体类中编写OneToMany关系 我试过这个：

private final ListProperty<Bill> bills = new SimpleListProperty<>();

@OneToMany(targetEntity = Bill.class, mappedBy = "invoice")
public ObservableList getBills() {
    return bills.get();
}

public void setBills(ObservableList value) {
    bills.set(value);
}

public ListProperty billsProperty() {
    return bills;
}

得到错误：＆＃34; oneTomany属性类型应为[java.util.colletion，java.util.List]

Answer 1

仅使用List而不是getter和setter函数中的ObservableList。

private final ListProperty<Bill> bills = new SimpleListProperty<>();

@OneToMany(targetEntity = Bill.class, mappedBy = "invoice")
public List getBills() {
    return bills.get();
}

public void setBills(List value) {
    bills.set(FXCollections.observableArrayList(value));
}

public ListProperty billsProperty() {
    return bills;
}
