我的类DCServeCeditor是DialogController的子类。这是一个看起来很普通的FXML控制器类：

class DCServRecEditor extends DialogController {

    private int m_dialogMode = DB.DBEDIT_MODE_ADD;
    private int m_selServ = -1;
    private GregorianCalendar m_cal = null;


    @FXML // ResourceBundle that was given to the FXMLLoader
    private ResourceBundle resources;

    @FXML // URL location of the FXML file that was given to the FXMLLoader
    private URL location;

    @FXML // fx:id="ancMatchSelector"
    private AnchorPane ancMatchSelector; // Value injected by FXMLLoader

    @FXML // fx:id="ancServEditor"
    private AnchorPane ancServEditor; // Value injected by FXMLLoader

    @FXML // fx:id="ancServRecEditor"
    private AnchorPane ancServRecEditor; // Value injected by FXMLLoader

        ...
}

我进行了两次和三次检查，以确保FXML中没有一个命名控件在controller类中也没有实例字段。所有实例字段都用@fxml标记。

FXML中controller类的名称与我的java文件相同，并且有适当的限定。该错误发生在调用initialize()之前，因此我不认为它与initialize()有任何关系，尽管我已经检查了它是否也用@fxml标记。

错误消息除了说它有修饰符“”之外，没有给我关于它有问题的成员的任何细节。我回到我的controller类，将所有具有默认访问权限的成员设为public，但我仍然得到错误。
我甚至不知道问题是从我的类的哪里来的。有人知道这里出了什么问题吗？

另一个令人尴尬的简单问题。

我很惊讶有人现在还没跳出来。

问题出在我的类dcservreceditor中。请注意，类是用default访问权限声明的。
