| ty.create("${" + sourceProperty + "}"),
field, BeanProperty.create("text"));
bindingGroup.addBinding(binding);
bindingGroup.bind();
return new JXLayer<jTextComponent>(field, new HibernateValidationUI(
sourceObject, sourceProperty));
}
}
createTextField()方法主要将给定对象属性的值与JTextField的text绑定，然后将JTextField纳入到 JXLayer的管理之下。这样一来，一旦用户在JTextField里面修改数据，这个改变就会同步到该对象属性 上，然后就引发了前面描述的一系列逻辑，最终改变的数据就会被Hiberante Validator加以验证。
最后，我们可以编写一个Demo application来看看效果如何，代码如下：
package de.jingge.main;
import de.jingge.domain.Country;

import net.miginfocom.swing.MigLayout;
import org.jdesktop.beansbinding.BindingGroup;
import org.jdesktop.jxlayer.JXLayer;
import static de.jingge.view.GuiComponentFactory.*;
public class ValidationApplicaton {
private BindingGroup bg;
private Country country;
private JXLayer<jTextComponent> codeField;
private JXLayer<jTextComponent> nameField;

}
ValidationApplicaton app = new ValidationApplicaton();
JFrame frame = new JFrame("Demo Validation Application");
frame.setPreferredSize(new Dimension(360, 150));
frame.getContentPane().add(app.buildPanel(), BorderLayout.CENTER);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setCenter(frame);
frame.setVisible(true);
frame.pack();
}
private static void setCenter(JFrame frame) {

}
public ValidationApplicaton() {
country = new Country();
bg = new BindingGroup();
}
