java实现mongoDB的多条件查询

需求：在mongDB客户端，我们很容易实现多条件查询，那么使用java操作时怎么实现呢

db.url.find({index:4,status:0,url:{$regex:"2016"}}).limit(1)

BasicDBObject doc5 = new BasicDBObject();
doc5.put("index", 3);
doc5.put("status", 0);
//doc5.put("url", "{$regex:'2016'}");错误的写法
BasicDBObject doc3 = new BasicDBObject();
doc3.put("$regex", "2016");
doc5.put("url", doc3);
FindIterable<Document> find = col.find(doc5);
