推荐答案

我不认为组件上有一个直接的方式做这个。
我知道的一种方法是使用 setSelectableDateRange（Date from，Date to） - 当您将日期设置为当前日期时，所有前一天单元格，年/月下降将被禁用。

I do not think there is a straight forward way on the component to do this. One way, that I know of is to use the setSelectableDateRange(Date from,Date to) - When you set the from date to current date, all previous day cells, year/month drop downs becomes disabled.

示例：

    JCalendar calendar = new JCalendar();
    calendar.setSelectableDateRange(new Date(),new SimpleDateFormat("MM-DD-YYYY").parse("05-05-2015"));

    PropertyChangeListener calendarChangeListener  = new PropertyChangeListener() {
        @Override
        public void propertyChange(PropertyChangeEvent evt) {
            Date selectedDate = ((JCalendar)evt.getSource()).getDate();
        }
    };
    calendar.addPropertyChangeListener("calendar",calendarChangeListener);

这将禁用在当前日期之前，05/05/2015之后的任何日期的选择

This will disable selection of any date before current date and after 05/05/2015

请注意，此API在其javadoc中未记录。但是，这仍然是一个可以预期的公共设置器。

Note that this API is not documented in their javadoc. But still this is a public setter that works as expected.

编辑，因为你想知道如何 JDateChooser 可以在类似的上下文中使用

EDIT since you want to know how JDateChooser can be used in similar context

    JDateChooser chooser = new JDateChooser();
    chooser.getJCalendar().setSelectableDateRange(new Date(),new SimpleDateFormat("MM-DD-YYYY").parse("05-05-2015"));
    chooser.getJCalendar().addPropertyChangeListener("calendar",...);
