swingx你可以到maven库里面搜索Jar包（google "maven repos"，出现很多maven库，随便找一个，搜索swingx，找最新的下载。如果你使用maven管理项目，那更好办了，把swingx放入依赖里面即可）。

JXDatepicker的使用方法：
// JXDatePicker提供了编辑器供用户直接输入日期，也提供了右侧按钮，点击按钮出现日期选择期供用户选择日期。
JXDatePicker datePicker = new JXDatePicker();
JXDatePicker datePicker1 = new JXDatePicker(new java.util.Date());
java.util.Date date = datePicker.getDate(); // 用户输入或选择日期后得到日期值
java.util.Date date1 = datePicker1.getDate(); // 用户输入或选择日期后得到日期值
//当然，你也可以指定用户输入日期的格式。
JXDatePicker datePicker2 = new JXDatePicker();
datePicker2.setFormats("yyyy.M.d", "yyyy-M-d");//可同时设置多种格式。setFormats(String...format)
JXMonthView的使用方法：
JXMonthView monthView = new JXMonthView();
monthView.setUnselectableDates(new java.util.Date());// 设置多个不可选择的日期，setUnselectableDates(java.util.Date ... date)
Setjava.util.Date unselectable = monthView.getSelectionModel().getUnselectableDates();// 获得当前有哪些不可选择日期
monthView.setFlaggedDates(date1,date2)// 设置多个被标记了的日期
Setjava.util.Date flaggedDates = monthView.getFlaggedDates();// 获得被标记的日期
Calendar calendar = monthView.getCalendar();// 获得日历对象
还有一些可set,get的属性罗列如下：
selectionMode
traversable
firstDayOfWeek
还有更多用法，看API吧。如果使用Maven，你可以自动下载javadoc和javasource。

* @Description:在原有基础上修改了以下内容：
* 1. 将容器由Frame改为了Dialog，以便在基于对话框的程序中也能够使用
* 2. 将最小日期由1980改为了1950，考虑到目前球员的出生日期可能早于1980年
* 3. 将初始显示格式设置为 yyyy年MM月dd日 格式，原有的小时去掉了，不适合于出生日期字段
