Just use "insertOne" method, not save.

    MongoCollection collection;
    String collectionName = "somename";
    String jsonObject = "{}";

    if (!mongoTemplate.collectionExists(collectionName)) {
        collection = mongoTemplate.createCollection(collectionName);
        logger.info("Collection %s was successfully created", collectionName);
    } else {
        collection = mongoTemplate.getCollection(collectionName);
    }

    collection.insertOne(Document.parse(jsonObject));
