如何计算从Java中使用SQL获取的两个时间戳之间的年/月/日（实际上不需要时间）？

以下是我正在使用的代码片段：

query = "SELECT bc.periodbeginningdate " +
            "FROM cus_billingcontract bc " +
            "WHERE cus_billingcontract_id = " + recordID;
Timestamp bDate = DB.getSQLValueTS(null, query);

query = "SELECT bc.periodenddate " +
            "FROM cus_billingcontract bc " +
            "WHERE cus_billingcontract_id = " + recordID;
Timestamp eDate = DB.getSQLValueTS(null, query);

Answer 1

您可以使用long将时间戳转换为getTime()：请点击此处查看大量信息：

然后，使用long值，您可以使用JodaTime库轻松访问月差异。
