ObjectRepository find method doesn't work when using Date type criteria about nitrite-java

[anidotnet]

The behaviour you are facing is due to Calendar object's milliseconds field. As Nitrite stores date object as a long field, you need to clear the Calendar object first if you want to use it as a filter.

I have created a test for you which will clarify this.

Test Case 1: Your test case

@Test
    public void testDate() {
        ObjectRepository<HtmlContentModel> repository = db.getRepository(HtmlContentModel.class);

        for (int i = 0; i < 5; i++) {
            HtmlContentModel model = new HtmlContentModel();
            Calendar calendar= Calendar.getInstance();
            calendar.set(2017 - i,1,1,0,0,0);
            model.publishTime = calendar.getTime();
            repository.insert(model);
        }

        assertEquals(repository.size(), 5);

        for (HtmlContentModel model : repository.find()) {
            System.out.println(model);
        }

        System.out.println("**************************");

        Calendar calendar=Calendar.getInstance();
        calendar.set(2015,1,1,0,0,0);
        final Date startTime=calendar.getTime();
        System.out.println("startTime: " + startTime + " - " + startTime.getTime());
        calendar.set(2017,1,1,0,0,0);
        final Date endTime=calendar.getTime();
        System.out.println("endTime: " + endTime + " - " + endTime.getTime());

        System.out.println("**************************");

        ObjectFilter objectFilter=ObjectFilters.and(ObjectFilters.gte("publishTime",startTime), ObjectFilters.lt("publishTime",endTime));
        Cursor<HtmlContentModel> cursor=repository.find(objectFilter, FindOptions.sort("publishTime",SortOrder.Ascending));
        List<HtmlContentModel> list = cursor.toList();
        for (HtmlContentModel model : list) {
            System.out.println(model);
        }
    }

    public static class HtmlContentModel implements Serializable {
        public Date publishTime;

        @Override
        public String toString() {
            return "html { " + publishTime.toString() + " - " + publishTime.getTime() + " }";
        }
    }

Output:

html { Wed Feb 01 00:00:00 IST 2017 - 1485887400192 }
html { Mon Feb 01 00:00:00 IST 2016 - 1454265000256 }

Test Case 2: What you should do (clearing the Calendar object's milliseconds field)

@Test
    public void testDate() {
        ObjectRepository<HtmlContentModel> repository = db.getRepository(HtmlContentModel.class);

        for (int i = 0; i < 5; i++) {
            HtmlContentModel model = new HtmlContentModel();
            Calendar calendar= Calendar.getInstance();
            calendar.clear();
            calendar.set(2017 - i,1,1,0,0,0);
            model.publishTime = calendar.getTime();
            repository.insert(model);
        }

        assertEquals(repository.size(), 5);

        for (HtmlContentModel model : repository.find()) {
            System.out.println(model);
        }

        System.out.println("**************************");

        Calendar calendar=Calendar.getInstance();
        calendar.clear();
        calendar.set(2015,1,1,0,0,0);
        final Date startTime=calendar.getTime();
        System.out.println("startTime: " + startTime + " - " + startTime.getTime());
        calendar.clear();
        calendar.set(2017,1,1,0,0,0);
        final Date endTime=calendar.getTime();
        System.out.println("endTime: " + endTime + " - " + endTime.getTime());

        System.out.println("**************************");

        ObjectFilter objectFilter=ObjectFilters.and(ObjectFilters.gte("publishTime",startTime), ObjectFilters.lt("publishTime",endTime));
        Cursor<HtmlContentModel> cursor=repository.find(objectFilter, FindOptions.sort("publishTime",SortOrder.Ascending));
        List<HtmlContentModel> list = cursor.toList();
        for (HtmlContentModel model : list) {
            System.out.println(model);
        }
    }

    public static class HtmlContentModel implements Serializable {
        public Date publishTime;

        @Override
        public String toString() {
            return "html { " + publishTime.toString() + " - " + publishTime.getTime() + " }";
        }
    }

Output:

html { Wed Feb 01 00:00:00 IST 2017 - 1485887400000 }
