Question

java中的mongoDB怎么分页,要代码，数据量较大

Answer 1

List<BasicDBObject> result = new ArrayList<BasicDBObject>();

if (tableName.length() > 0) {

if (cursor == null) {

coll = db.getCollection(tableName);

cursor = coll.find().skip(skipNum).limit(num);

}

while (cursor.hasNext()) {

BasicDBObject o = (BasicDBObject) cursor.next();

result.add(o);

}

}

但是调用出现了问题：

我这样查,
List<BasicDBObject> list1 = mongoDao.queryWithNum(LuceneTest.tableName, 100,100);

List<BasicDBObject> list2 = mongoDao.queryWithNum(LuceneTest.tableName, 200,100);

System.out.print("--结束,共" + list1.size() + "条---" + "--");

System.out.println(list2.size());
