Find documents with array that contains a specific value in mongodb using java

According to the answer provided in this link: Find document with array that contains a specific value, i have tried getting the items in java using this statement

searchQuery.put("arrayMine", new BasicDBObject("$in","[xxx]"));
OR
searchQuery.put("arrayMine", new BasicDBObject("$in","xxx"));

But it keeps saying the $in value must be an array while my arrayMine is an array. What should be the correct syntax in java?

Solution

  • Both variants you have are treating the value of BasicDBObject as String.

    Use

    searchQuery.put("arrayMine", new BasicDBObject("$in", Arrays.asList("xxx"))
