Date類型數據的加一天

 

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");

try {
                if (startDate != null && !startDate.isEmpty()) {
                    Predicate predicate = cb.greaterThanOrEqualTo(root.<Date>get(Customer_.crtTime),
                            sdf.parse(startDate));
                    predicates.add(predicate);
                }

                    Calendar cal = Calendar.getInstance(); cal.setTime(sdf.parse(endDate)); cal.add(Calendar.DATE, 1); Predicate predicate = cb.lessThanOrEqualTo(root.<Date>get(Customer_.crtTime), cal.getTime()); predicates.add(predicate);
                }
