Question

我按日期添加天数"Add day" 这是标准程序，但不幸的是我的Pentaho应用程序在c.setTime(dt);上中断，我显然不知道原因，因为例外没有任何意义。
所以另一个选择是解析日期并提取月，年和日以及+1到当天，但我必须处理Feburary和odd months。我脑子里只有这两个选项。

任何可以指导我任何其他选择的人？

Answer 1

此外，如果您正在使用Kettle / Pentaho数据集成，则可以使用Calculator步骤。提供的计算之一是“日期A + B天”。我经常使用它，它一直很适合我。

Answer 2

我遇到了同样的问题，这里的解决方案对我有用..

这是用户定义的Java类

中的一个问题

这是在尝试访问在try / catch块之外的try / catch块中设置的变量时引起的（即使先前已声明，但在try / catch中未设置，仍会出现此错误）。< / p>

Answer 3

尝试。

Calender cal=Calender.getInstance();

cal.add(Calender.DATE,1);

一个例子

    Calendar cal = Calendar.getInstance();
    System.out.println(cal.getTime());// out put Thu Aug 22 16:31:56 IST 2013
    cal.add(Calendar.DATE,1);
    System.out.println(cal.getTime());// out put Fri Aug 23 16:31:56 IST 2013

检查Demo。

如果以这种方式尝试，这应该可以正常工作。请在此处发表评论或发布您的代码，并附上例外情况。

Answer 4

另一种方法是使用Joda time

DateTime dateTime = new DateTime(date);
dateTime = dateTime.plusDays(1);

添加天数
