Я использую библиотеку Джексона, чтобы попытаться десериализовать XML в своем приложении для Android.

Градуировка, включающая Джексона, выглядит следующим образом:

 // Normal Jackson libraries
    compile 'com.fasterxml.jackson.core:jackson-core:2.12.3'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.12.3'
    compile "com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.12.3"
    implementation group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.12.3'
    implementation group: 'com.fasterxml.jackson.module', name: 'jackson-module-scala_2.11', version: '2.12.3'
    implementation 'com.fasterxml.jackson.datatype:jackson-datatype-joda:2.12.3'
 

Конфигурация XmlMapper для десериализации выглядит следующим образом:

 XmlMapper objectMapper = new XmlMapper();
                        objectMapper.registerModule(new JodaModule());
                        objectMapper.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
                        objectMapper.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
                        objectMapper.enable(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY);
                        objectMapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);
                        objectMapper.disable(DeserializationFeature.FAIL_ON_MISSING_CREATOR_PROPERTIES);
                        objectMapper.disable(DeserializationFeature.FAIL_ON_IGNORED_PROPERTIES);
                        objectMapper.disable(DeserializationFeature.FAIL_ON_NULL_FOR_PRIMITIVES);
                        objectMapper.disable(DeserializationFeature.FAIL_ON_NULL_CREATOR_PROPERTIES);
                        objectMapper.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);

                        ClinicalDocument res = objectMapper.readValue(s, ClinicalDocument.class);
 

Но в последней строке выше я получил следующую ошибку:

где класс кол-во это:

 import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlSeeAlso;
import javax.xml.bind.annotation.XmlType;


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "QTY")
@XmlSeeAlso({
    RTOMOPQ.class,
    RTOPQPQ.class,
    RTOQTYQTY.class,
    REAL.class,
    INT.class,
    PQ.class,
    MO.class,
    TS.class
})
public abstract class QTY extends ANY {

}
 

and the ANY class that QTY extends is:

 @XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "ANY")
@XmlSeeAlso({
    BL.class,
    ANYNonNull.class,
    CR.class,
    SLISTTS.class,
    GLISTPQ.class,
    SLISTPQ.class,
    GLISTTS.class,
    QTY.class,
    II.class,
    CD.class,
    URL.class,
    BIN.class
})
public abstract class ANY {

    @XmlAttribute(name = "nullFlavor")
    protected List<String> nullFlavor;

  
    public List<String> getNullFlavor() {
        if (nullFlavor == null) {
            nullFlavor = new ArrayList<String>();
        }
        return this.nullFlavor;
    }
}
 

Do you know how to solve this problem? I’m loosing hours without any success.

Thank you very much in advance!
