Java Swing 是否有任何好的免费日期和时间选择器？

There are a lot date pickers available but no date AND time picker. This is the closest I came across so far: Looking for a date AND time picker

有很多日期选择器可用，但没有日期和时间选择器。这是迄今为止我遇到的最接近的：寻找日期和时间选择器

Anybody?

有人吗？

For a time picker you can use a JSpinner and set a JSpinner.DateEditor that only shows the time value.

对于时间选择器，您可以使用 JSpinner 并设置仅显示时间值的 JSpinner.DateEditor。

JSpinner timeSpinner = new JSpinner( new SpinnerDateModel() );
JSpinner.DateEditor timeEditor = new JSpinner.DateEditor(timeSpinner, "HH:mm:ss");
timeSpinner.setEditor(timeEditor);
timeSpinner.setValue(new Date()); // will only show the current time

As you said Date picker is easy, there are many out there.

正如你所说的日期选择器很容易，那里有很多。

As for a Time picker, check out how Google Calendar does it when creating a new entry. It allows you to type in anything while at the same time it has a drop down in 30 mins increments. The drop down changes when you change the minutes.

至于时间选择器，请查看 Google 日历在创建新条目时是如何工作的。它允许您输入任何内容，同时以 30 分钟为增量进行下拉。当您更改分钟时，下拉列表会发生变化。

If you need to allow the user to pick seconds, then the best you can do is a typable/drop down combo

如果您需要允许用户选择秒数，那么您能做的最好的事情就是打字/下拉组合

Use the both combined.. that's what i did:

将两者结合使用..这就是我所做的：

public static JPanel buildDatePanel(String label, Date value) {
JPanel datePanel = new JPanel();

JDateChooser dateChooser = new JDateChooser();
if (value != null) {
    dateChooser.setDate(value);
}
for (Component comp : dateChooser.getComponents()) {
    if (comp instanceof JTextField) {
    ((JTextField) comp).setColumns(50);
    ((JTextField) comp).setEditable(false);
    }
}

datePanel.add(dateChooser);

SpinnerModel model = new SpinnerDateModel();
JSpinner timeSpinner = new JSpinner(model);
JComponent editor = new JSpinner.DateEditor(timeSpinner, "HH:mm:ss");
timeSpinner.setEditor(editor);
if(value != null) {
    timeSpinner.setValue(value);
}

datePanel.add(timeSpinner);

return datePanel;
}

There is the FLib-JCalendarcomponent with a combined Date and Time Picker.

还有就是FLib-JCalendar与组合日期和时间选择器组件。

You can extend the swingx JXDatePicker component:

您可以扩展 swingx JXDatePicker 组件：

"JXDatePicker only handles dates without time. Quite often we need to let the user choose a date and a time. This is an example of how to make use JXDatePicker to handle date and time together."

“JXDatePicker 只处理日期，没有时间。很多时候我们需要让用户选择日期和时间。这是一个如何使用 JXDatePicker 一起处理日期和时间的例子。”

EDIT: This article disappeared from the web, but as SingleShot discovered, it is still available in an internet archive. Just to be sure, here is the full working example:

编辑：这篇文章从网上消失了，但正如 SingleShot 发现的那样，它仍然可以在互联网档案中找到。可以肯定的是，这里是完整的工作示例：
