Spring数据mongodb查询skip（）无法正常工作。

Question

I discovered that skip() in a query using mongoOperations acts funny.

I have this code:

if (question.getCategory() == "" && question.getDifficulty() == 0 && question.getNumberOfCorrectAnswers() == 0) 
        return mongoOperations.find(new Query(Criteria.where("question").regex(questionPattern, "i"))
        .limit(getLimit()).skip(getSkip()), Question.class);

I use it in my search method. I want to do a pagination. For example limit the results to 10 and skip the first 5.

limit() works just fine, but skip() when it gets the value of 1 displays the 1st document in the collection. limit() is on 0 by default as to not shorten the range.

I checked in mongodb shell and skip(1) is viewing documents starting from the second one.

Anybody got an idea how to fix this?

Answer 1

Can you try this instead:

Criteria criteria = Criteria.where("question").regex(questionPattern, "i");
Query query = Query.query(criteria);
query.limit(getLimit());
query.skip(getSkip());
return mongoOperations.find(query, Question.class);
