Cannot parse XML using Jackson, model never gets populated

I am trying to parse bellow xml using Jackson library but with no luck. I tried few things with my model, and I don't see the problem...
XML:
<?xml version="1.0" encoding="UTF-8"?>
<litre version="1.1" creator="Dummy Creator"
xsi:schemaLocation="http://www.dummy.com/xmlschemas/DummyExtension.xsd>
<metadata>
<link href="dummy.com">
<text>Dummy</text>

<extensions>
<axtpx:DummyExtension>
<xtpx:hor>40000</xtpx:hor>
</axtpx:DummyExtension>
</extensions>
</pkrt>

<xtpx:hor>50000</xtpx:hor>
</axtpx:DummyExtension>
</extensions>
</pkrt>
</geskrt>
</krt>
</litre>
POJO:
#JacksonXmlRootElement(localName = "litre")
public #Data class Model {
#JacksonXmlProperty(localName = "pkrt")
#JacksonXmlElementWrapper(useWrapping = false)
private List<Data> entries;
public static #Data class Data {
#JacksonXmlProperty(isAttribute = true, localName = "data1")
private double dataOne;
#JacksonXmlProperty(isAttribute = true, localName = "data2")
private double dataTwo;
#JacksonXmlProperty(localName = "ints")
private double inters;
private String time;
#JacksonXmlProperty(namespace = "xtpx:hor")
private long hours;
}
}
While trying to deserialize with:
Model model = mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
.readValue(filePath.toFile(), Model.class);
parsing always passes with no exception, but entries list is always empty...
I would appreciate any help, thanx!

You most certainly have to do something like this:
#JacksonXmlRootElement(localName = "litre")
public #Data class Litre {
#JacksonXmlProperty(localName = "krt")
private Krt krt;
public static #Data class Krt {
#JacksonXmlProperty(localName = "geskrt")
private Geskrt geskrt;
}
public static #Data class Geskrt {
#JacksonXmlProperty(localName = "pkrt")
#JacksonXmlElementWrapper(useWrapping = false)
private List<Pkrt> pkrt;
}
public static #Data class Pkrt {
#JacksonXmlProperty(isAttribute = true, localName = "data1")
private double dataOne;
#JacksonXmlProperty(isAttribute = true, localName = "data2")
private double dataTwo;
#JacksonXmlProperty(localName = "ints")
private double inters;
private String time;
#JacksonXmlProperty(namespace = "xtpx:hor")
private long hours;
}
}

findAll UUID MongoRepository

I'm trying to achive a findAllByUUID using mongo-spring-boot, but with no luck.
What I have:
public interface CarMatchRepository extends MongoRepository<CarMatchEntity, String> {
List<CarMatchEntity> findAllByCarID(Iterable<UUID> ids);
CarMatchEntity findByCarID(UUID carID);
}
Function call:
public void addCarsToCollection(String id, List<UUID> carId) {
List<CarMatchEntity> entities = carMatchRepository.findAllByCarID(carId); <--- empty
}
If I call findByCarID() it retrieves correctly a single object (if exists) but using Iterable the query does not fail, but it never returns any object. Am I doing something wrong here or am I taking the wrong road for this problem?
Thanks!
Edit:
#Document(collection = "car_index")
public class CarMatchEntity implements Serializable {
#Id
private String id;
private UUID carID;
//partner data
private UUID partnerID;
private String partnerThumbURL;
private String partnerName;
private Date partnerMembershipSince;
// car location
private List<Double> location;
private String district;
private String city;
// car data
private CarType carType;
private String carBrand;
private String carModel;
private String carPlate;
private List<CarFeature> carFeatures;
private String carAddress;
private String description;
private BigDecimal hourFare;
private BigDecimal dayFare;
private BigDecimal weekFare;
private BigDecimal dailyPrice;
private BigDecimal suggestedHourlyPrice;
private BigDecimal suggestedDailyPrice;
private BigDecimal suggestedWeeklyPrice;
private String carThumbURL;
private Map<String, CarPhotos> carPhotosURL;
private CarAvailability availability;
private CarStatus carStatus;
private String carYear;
private FuelType fuelType;
#Transient
private DayOfWeek prohibitedDay;
private String carYearModel;
#Transient
private double partnerRating = 5.0;
private CarTransmission carTransmission;
private CarColor carColor;
private String odometer;
private Integer manufactureYear;
private String fipeCode;
private String renavam;
private String chassi;
private InsuranceCompany insuranceCompany;
private List<CarSpecialFeature> carSpecialFeatures;
private BigDecimal deductible;
private Boolean superCar;
public CarMatchEntity() {
}

Try using JSON based queries with SpEL expressions
#Query("{carID: { $in: ?0 } })")
List<CarMatchEntity> findAllByCarIds(List<UUID> ids);

Use
List<CarMatchEntity> findAllByCarIDIn(Iterable<UUID> ids);
instead of
List<CarMatchEntity> findAllByCarID(Iterable<UUID> ids);
UPDATE:
Did you try to explicitly declare JPQL query instead of relying on Spring Data query generation mechanism?
#Query("select e from CarMatchEntity e where e.carID in (:ids)")
List<CarMatchEntity> findAllByCarID(#Param("ids") Iterable<UUID> ids);
UPDATE 2:
Another solution I would try is to declare argument ids in findAllByCarIDIn method as Collection<UUID> instead of Iterable<UUID>.

How to collect all xml elements in a list?

I am using jackson-dataformat-xml.
I have the following classes:
public class CTHotel {
#JacksonXmlProperty(localName = "basic-info")
private HotelBaseInfo hotelBaseInfo;
//other properties and getters and setters
}
public class HotelBaseInfo {
#JacksonXmlProperty(localName = "hotel-name")
private String hotelName;
#JacksonXmlElementWrapper(localName = "hotel-amenities")
private List<HotelAmenity> hotelAmenities;
//other properties and getters/setters
}
public class HotelAmenity {
private String category;
private String description;
#JacksonXmlElementWrapper(localName = "amenities")
private List<String> amenities;
//other properties and getters/setters
}
My XML is this:
<hotels>
<hotel>
<basic-info>
<hotel-name>Hotel XYZ</hotel-name>
<hotel-amenities>
<hotel-amenity>
<category>F&B</category>
<description>Random Text</description>
<amenities>
<amenity>Cafe</amenity>
<amenity>Bar</amenity>
<amenity>Rastaurant</amenity>
</amenities>
</hotel-amenity>
<hotel-amenity>
...
</hotel-amenity>
</hotel-amenities>
</basic-info>
</hotel>
<hotel>
...
</hotel>
</hotels>
My question is, how can I map amenities as list of strings in my HotelAmenity class as mentioned above ? What annotation should I use on amenities field ?
#JacksonXmlElementWrapper annotation on hotelAmenities field of Hotel class is working just fine.
I get the below error while mapping :
com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_OBJECT token
at [Source: java.io.StringReader#507bcc81; line: 3, column: 1039] (through reference chain: com.example.response.HotelSearchResponse["hotels"]->java.util.ArrayList[2]->com.example.response.CTHotel["basic-info"]->com.example.response.HotelBaseInfo["hotel-amenities"]->java.util.ArrayList[1]->com.example.response.HotelAmenity["amenities"]->java.util.ArrayList[9])

...

Here's the code, that I hope would answer your question:
/**Class Hotels*/
#JacksonXmlRootElement(localName = "hotels")
public class Hotels {
#JacksonXmlElementWrapper(useWrapping = false)
private List<Hotel> hotel;
//Other getters and setters
}
/**Class Hotel*/
#JacksonXmlRootElement(localName = "hotel")
public class Hotel {
#JacksonXmlProperty(localName = "basic-info")
private HotelBaseInfo hotelBaseInfo;
//Other getters and setters
}
/**Class HotelBaseInfo*/
public class HotelBaseInfo {
#JacksonXmlProperty(localName = "hotel-name")
private String hotelName;
#JacksonXmlElementWrapper(localName = "hotel-amenities")
private List<HotelAmenity> hotelAmenities;
//Other getters and setters
}
/**Class HotelAmenity*/
public class HotelAmenity {
private String category;
private String description;
#JacksonXmlElementWrapper(localName = "amenities")
private List<Amenities> amenity;
static class Amenities {
#JacksonXmlText
private String value;
}
//Other getters and setters
}

Here's what worked for me:
public class JacksonXmlParsing {
#JacksonXmlRootElement(localName = "hotels")
static class HotelSearchResponse {
#JacksonXmlElementWrapper(localName = "hotel")
private List<CTHotel> hotels;
//other properties and getters and setters
}
static class CTHotel {
#JacksonXmlProperty(localName = "hotel-name")
private String hotelName;
#JacksonXmlElementWrapper(localName = "hotel-amenities")
private List<HotelAmenity> hotelAmenities;
//other properties and getters and setters
}
static class HotelAmenity {
private String category;
private String description;
#JacksonXmlElementWrapper
private List<String> amenities;
//other properties and getters/setters
}
public static void main(String[] args) throws IOException {
XmlMapper xmlMapper = new XmlMapper();
File file = new File("./src/main/resources/file.xml");
HotelSearchResponse response = xmlMapper.readValue(file, HotelSearchResponse.class);
System.out.println(response);
}
}
Output:
HotelSearchResponse(hotels=[CTHotel(hotelName=Hotel XYZ, hotelAmenities=[HotelAmenity(category=F&B, description=Random Text, amenities=[Cafe, Bar, Rastaurant])])])
But basic-info tag is missed, I could find out why.

SimpleXMLConverter parse xml nodes

I'm stuck. How to parse Node with same name child node?
In this example i need nodes with rate attribute.
<xml>
<Rates>
<Rates winrate_cap="9999">
<Rates rate="323"/>
<Rates rate="343"/>
<Rates rate="2338"/>
<Rates rate="233"/>
</Rates>
</Rates>
</xml>
My response wrapper class:
#Root(name = "xml", strict = false)
public class XMLResponse {
#ElementList(entry = "Rates")
public List<Rates> response;
public static class Rates {
#Attribute(name = "winrate_cap", required = false)
public String winrate_cup;
#ElementList(required = false, entry = "Rates")
public List<Rates> rates;
}
public static class Rates {
#Attribute(name = "rate", required = false)
public String rate;
}
}

You are on the right way. As you have many Rates here, better name the class more with more context and set the xml name via Annotation.
I've separated the XMLResponse and Rates classes, but this doesn't make any difference.
The class XMLRespone maps the <xml>...</xml> part:
#Root(name = "xml")
public class XMLRespone
{
#Element(name = "Rates")
private Rates rates;
// ...
}
All types for <Rates...>...</Rates> is done by Rates class (and it's inner classes, which map the structure:
#Root(name = "Rates")
public class Rates
{
#Element(name = "Rates")
private RateList rates;
// ...
public static class RateList
{
#ElementList(entry = "Rates", inline = true)
private ArrayList<RateValue> values;
#Attribute(name = "winrate_cap", required = true)
private int winrateCap;
// ...
}
public static class RateValue
{
#Attribute(name = "rate", required = true)
private int rate;
// ...
}
}
Deserializing your XML gives this output (using generated toString()):
XMLRespone{rates=Rates{rates=RateList{values=[RateValue{rate=323}, RateValue{rate=343}, RateValue{rate=2338}, RateValue{rate=233}], winrateCap=9999}}}

Can not unmarshall a (XML with namespace) inputstream into object

When I send a request to web service the following response will be received. I am using the following code to unmarshall the response XML to an object, but it seems nothing will be put into the object.

Since your XML document is namespace qualified you will need to use the package level #XmlSchema annotation to map the namespace qualification.
#XmlSchema(
namespace = "example.com",
elementFormDefault = XmlNsForm.QUALIFIED)
package example;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
