Question

我正在尝试使用Struts2将数据从excel导入MySQL。在这里我导入了所有数据，但是我遇到了日期问题。这个excel有一个列作为月（2014年4月）。

我还在数据库中导入了Month列。但每当我使用Month字段检索时，它会显示2014年4月，2014年8月，2014年7月，2014年1月的数据。实际上，我的数据库总共（2014年4月至2015年4月）1年的数据。每个月有440条记录。

我创建了J.S.P页面，用于在数月之间检索数据。

MySQL数据库：

这里我试图在几个月之间检索数据。我试图找回 Apr-2014和Jun-2014之间的数据。但是，我得到了像Apr-2014这样的数据 Aug-2014，Jul-2014和Jun-2014。我需要数据像这样Apr-2014，May-2014和Jun-2014。请帮助我在几个月之间从MySQL获取数据。
