private void getUsersWithin24Hours(String id, Map < String, Object > payload) throws JSONException {
JSONObject json = new JSONObject(String.valueOf(payload.get("data")));
Query query = new Query();
query.addCriteria(Criteria.where("user_id").is(id).and("timezone").in(json.get("timezone")).and("gender").in(json.get("gender")).and("locale").in(json.get("language")).and("time").gt(getDate()));
mongoTemplate.getCollection("user_log").distinct("user_id", query.getQueryObject());
}
I was going to made a query and get result from mongodb and I was succeed with mongo terminal command:
db.getCollection('user_log').find({"user_id" : "1", "timezone" : {$in: [5,6]}, "gender" : {$in : ["male", "female"]}, "locale" : {$in : ["en_US"]}, "time" : {$gt : new ISODate("2017-01-26T16:57:52.354Z")}})
but from java when I was trying it gave me below error.
org.bson.codecs.configuration.CodecConfigurationException: Can't find a codec for class org.json.JSONArray
What is the ideal way to do this?
Hint : actually I think in my code error occurred of this part json.get("timezone"). because it contains array. When I am using hardcode string arrays this code works
Here's an example of MongoDB from MongoDB University course with a MongoDB database named "students" with a collection named "grades" :

You don't have to use JSONObject/JSONArray
for conversion.
Replace with below line if the payload.get("data")
is Map
BasicDBObject json = new BasicDBObject(payload.get("data"));
Replace with below line if the payload.get("data")
holds json string.
BasicDBObject json =(BasicDBObject) JSON.parse(payload.get("data"));
