Java 如何删除JFormattedTextField的掩码？

我有一个由两个单选按钮控制的JFormattedTextField。在其中一个RadioButton中，我设置了掩码，另一个我希望清除掩码并正常键入。设置为“正常类型”后，它不会返回getText的值，该值仅在设置掩码时返回

如何解决这个问题

private void setMask() {
    MaskFormatter formatter = null;
    try {
        txtPesquisar.setValue(null);
        if (rbNome.isSelected()) {
            //clear mask to type normally
            formatter = new MaskFormatter("****************************************");
            formatter.setPlaceholderCharacter(' ');
        } else {
            //set mask
            formatter = new MaskFormatter("###.###.###-##");
            formatter.setPlaceholderCharacter(' ');
        }
        txtPesquisar.setFormatterFactory(new DefaultFormatterFactory(formatter));
        txtPesquisar.requestFocus();
        txtPesquisar.selectAll();
    } catch (ParseException ex) {
        ex.printStackTrace();
    }
}

在调用getValue之前，请确保在JFormattedTextField上调用CommittedIt。根据getValue部分：

返回最后一个有效值。根据AbstractFormatter的编辑策略，这可能不会返回当前值。当前编辑的值可以通过调用CommittedIt然后调用getValue来获得。 返回：

例如：

import java.awt.event.ActionEvent;
import java.awt.event.KeyEvent;
import java.text.ParseException;

import javax.swing.*;
import javax.swing.text.DefaultFormatterFactory;
import javax.swing.text.MaskFormatter;

在调用getValue之前，是否在JFormattedTextField上调用CommittedIt？如果没有，则需要执行此操作。在调用getValue之前，是否在JFormattedTextField上调用CommittedIt？如果没有，您将希望这样做。
