How to implement multiple query condition with Spring Data MongDB? - mongodb

Question

I'm starting learn spring data mongodb. Currently, I try to implement multiple condition query with Spring Data MongoDB.
First I have a sample collection
{
"_id": "df05532f-8893-4802-8710-ab92056c9c77",
"objectId": {
"$numberLong": "1"
},
"creator": {
"_id": {
"$numberLong": "3"
},
"username": "magic"
},
"content": "7878787887",
"attachments": [],
"pinned": false,
"histories": [
{
"content": "new new comment 2222",
"createdAt": {
"$date": {
"$numberLong": "1664970753576"
}
}
},
{
"content": "update me",
"createdAt": {
"$date": {
"$numberLong": "1664970753691"
}
}
},
{
"content": "update me3333",
"createdAt": {
"$date": {
"$numberLong": "1664970753734"
}
}
},
{
"content": "44444455666",
"createdAt": {
"$date": {
"$numberLong": "1664970753740"
}
}
}
],
"contentUpdateAt": {
"$date": {
"$numberLong": "1664970753745"
}
},
"createdAt": {
"$date": {
"$numberLong": "1664970753576"
}
},
"lastModifiedAt": {
"$date": {
"$numberLong": "1664970753772"
}
}
}
I'm trying to find a partial document when the array histories has one element that matched with content equals 44444455666
With MongoDB CLI, I completed build the query like
db.ticket_detail_comments.find(
{
histories: {
$elemMatch: {
content: "44444455666"
}
},
_id : "df05532f-8893-4802-8710-ab92056c9c77"
},
{ "histories.$": 1, name: 1 }
)
The result was exactly what I expected
{
"_id": "df05532f-8893-4802-8710-ab92056c9c77",
"histories": [
{
"content": "44444455666",
"createdAt": {
"$date": {
"$numberLong": "1664970753740"
}
}
}
]
}
When I tried to build query with Spring Data MongoDB (using MongoDbTemplate) I can't find any way to build query look like in console. I tried addOperation but seem not work,
I tried to build 2 separated Criteria (one, two) that match with 2 condition I expected, then combine them with andOperation like new Criteria().andOperator(one).andOperator(two);. The unhappy part is the query generated is so different
db.ticket_detail_comments.find(
{
"$and": [
{
histories: {
$elemMatch: {
content: "44444455666"
}
},
_id : "df05532f-8893-4802-8710-ab92056c9c77"
},
{ "histories.$": 1, name: 1 }
]
}
)
With this query, I always get a null value. Can anyone help me with that? What is correct Criteria syntax I should use?
Thanks for reading.
UPDATE
I created a small demo, let's see
Data in Mongo Collection look like
{
"_id": "dad9db98-241b-40fa-aab4-af1671f97631",
"data": "demo",
"children": [
{
"name": "tim",
"age": 19
},
{
"name": "alex",
"age": 18
}
],
"_class": "com.example.demo.Data"
}
MONGOCLI
db.data.find(
{
children: {
$elemMatch: {
name: "alex"
}
},
_id : "dad9db98-241b-40fa-aab4-af1671f97631"
},
{ "children.$": 1}
)
=> Result:
{ _id: 'dad9db98-241b-40fa-aab4-af1671f97631',
children: [ { name: 'alex', age: 18 } ] }
JAVA CODE
package com.example.demo;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.NoArgsConstructor;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Criteria;
import org.springframework.data.mongodb.core.query.Query;
import javax.annotation.PostConstruct;
import java.util.List;
import java.util.UUID;
#SpringBootApplication
public class DemoApplication {
private final MongoTemplate template;
public DemoApplication(MongoTemplate template) {
this.template = template;
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#PostConstruct
public void init() {
Data.Child child1 = Data.Child.builder()
.name("alex")
.age(18)
.build();
Data.Child child2 = Data.Child.builder()
.name("tim")
.age(19)
.build();
final String id = UUID.randomUUID().toString();
Data data = Data.builder()
.id(id)
.data("demo")
.children(List.of(child2, child1))
.build();
template.save(data, "data");
Query query = Query.query(
Criteria.where("_id").is(id).and("children")
.elemMatch(Criteria.where("name").is("alex"))
);
query.fields().position("children", 1);
var r = template.findOne(query, Data.class, "data");
System.out.printf("DEBUG");
}
}
#lombok.Data
#AllArgsConstructor
#NoArgsConstructor
#Builder
class Data {
private String id;
private String data;
private List<Child> children;
#lombok.Data
#AllArgsConstructor
#NoArgsConstructor
#Builder
static class Child {
private String name;
private Integer age;
}
}
=> Result: Data Object with 2 elements in children list.
But what I expected is Data Object has one element in children list like resut from CLI
