Как сериализовать JAXBElement?

Question

Я использую:

• GSON 2.3.1
• апач-CXF-3.1.1
• JBoss EAP 6,4

Я использую wsdl2java создать клиент WebService из WSDL.

я генерировать классы с:

@XmlElementRef(name = "FMLA_Code", namespace = "http://www.ultipro.com/contracts", type = JAXBElement.class) 
protected JAXBElement<String> fmlaCode; 

При получении объекта обратно от вызова WebService Я хочу, чтобы сделать ответ JSON вызывающей

EmploymentInformationGetResponse response =    port.getEmploymentInformationByEmployeeIdentifier(employeeNumberIdentifier); 
GsonBuilder gsonBuilder = new GsonBuilder(); 
gsonBuilder.registerTypeHierarchyAdapter(EmploymentInformationGetResponse.class, new EmploymentInformationGetResponseAdapter()); 
Gson gson = gsonBuilder.disableHtmlEscaping().create(); 
String s = gson.toJson(response); 
System.out.println(s); 

Результат содержит

fmlaCode=javax.xml.bind.JAXBElement@3191394e 

Каков наилучший способ получить ценность?

Я могу, но не хотел бы изменять сгенерированные классы, поскольку их, возможно, потребуется сгенерировать снова позже.

Я попытался создать адаптер типа для JAXBElement, но не дозвонились:

public class JAXBElementAdapter extends TypeAdapter<JAXBElement> { 

    @Override 
    public void write(JsonWriter jsonWriter, JAXBElement jaxbElement) throws IOException { 
     if (jaxbElement == null) { 
      jsonWriter.nullValue(); 
      return; 
     } 
     JAXBElement e = jaxbElement; 
     jsonWriter.value(e.getValue() != null ? e.getValue().toString() : ""); 
    } 

    @Override 
    public JAXBElement read(JsonReader jsonReader) throws IOException { 
     return null; 
    } 
} 

Я использовал этот код для регистрации адаптера:

gsonBuilder.registerTypeHierarchyAdapter(JAXBElement.class, new JAXBElementAdapter()); 

Вот сгенерированный EmploymentInformationGetResponse

import javax.xml.bind.JAXBElement; 
import javax.xml.bind.annotation.XmlAccessType; 
import javax.xml.bind.annotation.XmlAccessorType; 
import javax.xml.bind.annotation.XmlElementRef; 
import javax.xml.bind.annotation.XmlType; 
import java.util.List; 

/**

*/ 
@XmlAccessorType(XmlAccessType.FIELD) 
@XmlType(name = "EmploymentInformationGetResponse", propOrder = { 
    "results" 
}) 
public class EmploymentInformationGetResponse 
    extends GetResponse 
{ 

    @XmlElementRef(name = "Results", namespace = "http://www.ultipro.com/contracts", type = JAXBElement.class) 
    protected JAXBElement<ArrayOfEmploymentInformation> results; 

    /** 
    * Gets the value of the results property. 
    * 
    * @return 
    *  possible object is 
    *  {@link JAXBElement }{@code <}{@link ArrayOfEmploymentInformation }{@code >} 
    *  
    */ 
    public JAXBElement<ArrayOfEmploymentInformation> getResults() { 
     return results; 
    } 

    /** 
    * Sets the value of the results property. 
    * 
    * @param value 
    *  allowed object is

    *  
    */ 
    public void setResults(JAXBElement<ArrayOfEmploymentInformation> value) { 
     this.results = value; 
    } 

И EmploymentInformation без ge тестеры и сеттеры

Answer 1

Я не уверен, почему ваш код не работает. Я думаю, что наиболее вероятная проблема заключается в том, что JAXBElement является параметризованным типом, поэтому вам нужно указать его с параметром generic type.

Попробуйте это вместо того, чтобы при регистрации TypeAdapter:

gsonBuilder.registerTypeAdapter(
     new TypeToken<JAXBElement<String>>(){}.getType(), 
     new JAXBElementAdapter()); 

Answer 2

Вам нужно сделать: Gson gson = new GsonBuilder() .registerTypeAdapter(JAXBElement.class, new JAXBElementAdapter()) .create();
