Conexão com MongoDB
Instrução de Trabalho
Localização do MongoDB:
O servidor se encontra no site:
https://mongolab.com/
Esse Website fornece uma Plataforma como serviço de MongoDB (PaaS).
Não é necessário acessa-lo para desenvolver pra ele ou para se conectar nele, mas se for
necessário:
Usuário: labsoftlara
Senha: labsoftlara123
Comandos para se conectar ao banco de dados:
MongoClientURI uri
= new MongoClientURI("mongodb://labsoftlara:labsof
[email protected]:39000/lara");
MongoClient client = new MongoClient(uri);
DB db = client.getDB(uri.getDatabase());
Programa exemplo para se conectar e adicionar dados no
Banco de Dados:
import java.net.UnknownHostException;
import com.mongodb.*;
public class JavaSimpleExample {
// Extra helper code
public static BasicDBObject[] createSeedData(){
BasicDBObject seventies = new BasicDBObject();
seventies.put("decade", "1970s");
seventies.put("artist", "Debby Boone");
seventies.put("song", "You Light Up My Life");
seventies.put("weeksAtOne", 10);
BasicDBObject eighties = new BasicDBObject();
eighties.put("decade", "1980s");
eighties.put("artist", "Olivia Newton-John");
eighties.put("song", "Physical");
eighties.put("weeksAtOne", 10);
BasicDBObject nineties = new BasicDBObject();
nineties.put("decade", "1990s");
nineties.put("artist", "Mariah Carey");
nineties.put("song", "One Sweet Day");
nineties.put("weeksAtOne", 16);
