Using Jackson and Mongo Java Driver to insert and retrieve a POJO from the MongoDB

MongoPOJO

      // Person is a POJO, upload to db, retrieve from db

      Person person = new Person();
    	
    	person.setName("Evan Thompson");
    	person.setNickname("Unc");

    	ObjectMapper mapper = new ObjectMapper();  // can reuse, share globally
    	
    	try {
			String peep = mapper.writeValueAsString(person);
			Document doc = Document.parse(peep);  // this is what shortens the add to db
			collection.insertOne(doc);
		} catch (JsonProcessingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
    	
    	Bson filter = Filters.eq("name", "Evan Paul Leslie Thompson");
    	Bson projections = Projections.exclude("_id");

    	MongoCursor<Document> cur = collection.find().projection(projections).iterator();
    	
    	
    	
    	try {
    		while (cur.hasNext()) {
    			Document doc = cur.next();
    			
    			try {
					Person pers = mapper.readValue(doc.toJson(), Person.class);
					System.out.println(pers.getName());
			    	System.out.println(pers.getNickname());
				} catch (JsonParseException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (JsonMappingException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				} catch (IOException e) {

    		}
    	}
    	finally {
