java - 年月日的 Joda 期间

Question

我正在使用以下代码来获取年、月、日中的两个日期之间的差异

tenAppDTO.getTAP_PROPOSED_START_DATE()=2009-11-01  
tenAppDTO.getTAP_PROPOSED_END_DATE()=2013-11-29                                                                         
ReadableInstant r=new DateTime(tenAppDTO.getTAP_PROPOSED_START_DATE());
ReadableInstant r1=new DateTime(tenAppDTO.getTAP_PROPOSED_END_DATE());
Period period = new Period(r, r1);  
period.normalizedStandard(PeriodType.yearMonthDay());
years =  period.getYears();
month=period.getMonths();
day=period.getDays();   
out.println("year is-:"+years+"month is -:"+ month+"days is -:"+ day);

通过使用上面的代码我得到结果年是-:4 月是-:0 天是-:0但实际结果是年是-:4 月是-:0 天是-:28

请提供解决方案

Answer 1

你可以尝试改变

Period period = new Period(r, r1); 

与

Period period = new Period(r, r1, PeriodType.yearMonthDay());

你可以这样尝试:

tenAppDTO.getTAP_PROPOSED_START_DATE()=2009-11-01  
tenAppDTO.getTAP_PROPOSED_END_DATE()=2013-11-29                                                                         
ReadableInstant r=new DateTime(tenAppDTO.getTAP_PROPOSED_START_DATE());
ReadableInstant r1=new DateTime(tenAppDTO.getTAP_PROPOSED_END_DATE());
Period period = new Period(r, r1, PeriodType.yearMonthDay());   //Change here  
period.normalizedStandard(PeriodType.yearMonthDay());
years =  period.getYears();
month=period.getMonths();
day=period.getDays();   
out.println("year is-:"+years+"month is -:"+ month+"days is -:"+ day);
