我想从以下文档中获取uniq account_numbers。为什么mongoTemplate返回数字类型(int)的列值是双倍的?
{
"_id" : ObjectId("5825e49785a4caf2bfa64a2f"),
"profit" : "",
"account_number" : 10,
"m_number" : "",
"registration_number" : "",
"page_number" : "",
"entry_date" : ISODate("2016-04-01T07:35:35Z"),
"narration" : "By cash",
"voucher_number" : "",
"debit_credit" : 6150,
"account_code" : 2102,
"created_at" : ISODate("2016-04-01T07:35:35Z"),
"updated_at" : ISODate("2016-04-01T07:35:35Z"),
"employee_id" : 0,
"balance" : 0,
"credit" : 0,
"debit" : 0,
"particulars" : "",
"since_last" : 0,
"transaction_type" : 0,
"voucher_path" : "",
"branch" : "",
"auto_voucher_number" : "",
"check_book_series" : ""
}
account_number类型是数字,我想要使用Spring Mongo模板以int形式获取它。
Query query = new Query();
query.addCriteria(Criteria.where("account_code").is(accountCode).and("account_number").exists(true));
return List accounts = mongoTemplate.getCollection("transaction").distinct("account_number", query.getQueryObject());
上面的代码是返回列表帐户。查看调试结果
accounts = {[email protected]} size = 2815
0 = {[email protected]} "1626.0"
1 = {[email protected]} "1670.0"
2 = {[email protected]} "2936.0"
3 = {[email protected]} "2295.0"
4 = {[email protected]} "1010.0"
5 = {[email protected]} "1471.0"
6 = {[email protected]} "3333.0"
7 = {[email protected]} "1469.0"
8 = {[email protected]} "3445.0"
9 = {[email protected]} "3193.0"
10 = {[email protected]} "219.0"
11 = {[email protected]} "2509.0"
12 = {[email protected]} "3750.0"
13 = {[email protected]} "3425.0"
简短的问题是 - 如何从文档中获取int类型列表以及为什么返回双类型?
这里是文档的POJO,可能是我需要在现场定义的东西?
@Document(collection = "transaction")
public class Transaction implements Serializable {
private static final Long serialVersionUID = 1L;
@Id
//@GeneratedValue(strategy = GenerationType.IDENTITY)
@Field(value = "id")
private String id;
@Field(value = "account_code")
private Integer accountCode;
@Field(value = "account_number")
private Integer accountNumber;
知道了!谢谢。 – amjad
我无法控制集合以更改类型。我只是获取了值并提取了int值。再次感谢! – amjad
