【MongoDB】Java驱动读写数组

经常不用就忘了如何操作，记录一笔。

写

MongoClient client = new MongoClient(host, port);MongoDatabase db = client.getDatabase(testdb);MongoCollection<Document> col = db.getCollection(testcol);String[] color = {"red", "blue", "green"};Document doc = new Document("color", Arrays.asList(color));col.insertOne(doc);

读

Document query = new Document("color", "red");MongoCursor<Document> c = col.find(query).iterator();while (c.hasNext()) {      Document sub = c.next();      System.out.println(sub.get("color"));      System.out.println(sub);}
