浅谈java实现mongoDB的多条件查询

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 find = col.find(doc5);
