JTable在两个日期之间的rowfilter，同一列

问题描述

如何在两个日期之间实现RowFilter?日期为字符串格式.是否有必要将格式更改为日期格式以应用RegexFilter?

How can I implement a RowFilterbetween two dates? The dates are in string format. Is it necessary to change the format to a date format to apply a RegexFilter?

我尝试使用以下内容，但失败了:

I tried using the following, but failed :

DefaultTableModel model = (DefaultTableModel) easypath.masteBusiness_table.getModel();
easypath.masteBusiness_table.setModel(model);
TableRowSorter<TableModel> rowSorter = new TableRowSorter<>(easypath.masteBusiness_table.getModel());
easypath.masteBusiness_table.setRowSorter(rowSorter);
rowSorter.setRowFilter(RowFilter.regexFilter(startD+"\\s+(.*?)\\s+"+endD));

我知道我对过滤错误，因为(startD+"\\s+(.*?)\\s+"+endD)); 仅用于搜索单个字符串，但作为新手，我非常感谢任何建议.

I know I am wrong with the filtering as (startD+"\\s+(.*?)\\s+"+endD)); is only for searching a single string but as a novice I would very much appreciate any suggestion.

更新
我刚刚看到了这个内容( http://docs.oracle. com/javase/7/docs/api/javax/swing/RowFilter.html )，其中RowSorter<M,I>，M是模型，而I是不符合我的条件的整数值

UPDATE
I just saw this (http://docs.oracle.com/javase/7/docs/api/javax/swing/RowFilter.html) where RowSorter<M,I>, M is the model and I is an integer value, which does not match my criteria

推荐答案

您应该将Date存储在TableModel中，而不是日期的字符串表示形式.

You should be storing a Date in the TableModel not a String representation of the date.

然后您可以使用RowFilter.

可以使用带有两个日期过滤器的和"过滤器来代替正则表达式过滤器.像这样:

Instead of a regex filter you can use an "and" filter with two date filters.Something like:

List<RowFilter<Object,Object>> filters = new ArrayList<RowFilter<Object,Object>>(2);
filters.add( RowFilter.dateFilter(ComparisonType.AFTER, startDate) );
filters.add( RowFilter.dateFilter(ComparisonType.BEFORE, endDate) );
rf = RowFilter.andFilter(filters);
sorter.setRowFilter(rf);

在排序和过滤上阅读Swing教程.有关如何使用过滤器的更多信息和工作示例.
