In order to deserialize an XMLGregorianCalendar flexjson raise a JSonException with the following message:
"There was an exception trying to instantiate an instance of javax.xml.datatype.XMLGregorianCalendar"
This occours because the class XMLGregorianCalendar has not a default constructor with no parameter as flexjson is supposed to have.
To avoid this you need to implement the flexjson.ObjectFactory interface to instantiate and build a well-defined XMLGregorianCalendar object.
Suppose we have a simple class as follows:
public class Foo{
private XMLGregorianCalendar startDate;
private XMLGregorianCalendar endDate;
public XMLGregorianCalendar getStartDate(){return startDate;}
public void setStartDate(XMLGregorianCalendar start){this.startDate = start;}
public XMLGregorianCalendar getEndDate(){return endDate;}
public void setEndDate(XMLGregorianCalendar end){this.endDate = end;}
}
Example of ObjectFactory implementation:
public class XMLGregorianCalendarFactory implements ObjectFactory {
@Override
public Object instantiate(ObjectBinder context, Object value, Type targetType,
Class targetClass) {
try {
XMLGregorianCalendar result = DatatypeFactory.newInstance().newXMLGregorianCalendar();
JSONDeserializer jd = new JSONDeserializer();
String input = new JSONSerializer().deepSerialize(value);
jd.deserializeInto(input, result);
return result;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
To force flexjson uses our implementation, we need to pass it with the use method, as shown below:
JSONDeserializer jd = new JSONDeserializer();
jd.use(XMLGregorianCalendar.class, new XMLGregorianCalendarFactory());
Foo target = new Foo();
jd.deserializeInto(json, target);
After jd.deserializeInto(json, target) execute, the target object Foo will be correctly instatiate. (If we provide a valid json string!)
