ClassCastException Beansbinding Java

你能告诉我为什么在这里出现

ClassCastException

exception吗

protected void initDataBindings() {
    BeanProperty<Apprentice, String> apprenticeBeanProperty = BeanProperty.create("vorname");
    ObjectProperty<JTextField> jTextFieldObjectProperty = ObjectProperty.create();
    AutoBinding<Apprentice, String, JTextField, JTextField> autoBinding = Bindings.createAutoBinding(UpdateStrategy.READ_WRITE, apprentice, apprenticeBeanProperty, txtVorname, jTextFieldObjectProperty);
    autoBinding.bind();
}

java有attributee“vorname”（德语中的firstname），这是一个包含getter和setter的私有字段

private String vorname;

public Apprentice(){
    ;
}

public String getVorname() {
    return vorname;
}

public void setVorname(String vorname) {
    this.vorname = vorname;
}

我自己找到了解决办法，我把“自我对象”而不是“文本”绑定为如下所示：

protected void initDataBindings() {
    BeanProperty<Apprentice, String> apprenticeBeanProperty_1 = BeanProperty.create("vorname");
    BeanProperty<JTextField, String> jTextFieldBeanProperty_1 = BeanProperty.create("text");
    AutoBinding<Apprentice, String, JTextField, String> autoBinding_1 = Bindings.createAutoBinding(UpdateStrategy.READ_WRITE, apprentice, apprenticeBeanProperty_1, txtVorname, jTextFieldBeanProperty_1);
    autoBinding_1.bind();
}

受保护的void initDataBindings（）{
BeanProperty学徒BeanProperty_1=BeanProperty.create（“vorname”）；
BeanProperty jTextFieldBeanProperty_1=BeanProperty.create（“文本”）；
自动绑定自动绑定\u 1=绑定。创建自动绑定（UpdateStrategy.READ\u WRITE，peedient，peediateBeanProperty\u 1，txtVorname，jTextFieldBeanProperty\u 1）；
自动绑定_1.bind（）；
}

无论如何，谢谢你：）

protected void initDataBindings() {
    BeanProperty<Apprentice, String> apprenticeBeanProperty_1 = BeanProperty.create("vorname");
    BeanProperty<JTextField, String> jTextFieldBeanProperty_1 = BeanProperty.create("text");
    AutoBinding<Apprentice, String, JTextField, String> autoBinding_1 = Bindings.createAutoBinding(UpdateStrategy.READ_WRITE, apprentice, apprenticeBeanProperty_1, txtVorname, jTextFieldBeanProperty_1);
    autoBinding_1.bind();
}
