Java Question

Switch off java.langObject initialization in podam

I have POJOs:

class PersonJob {

private PersonAddress address;

//a buch of fields (non Object type)
}

class PersonAddress extends AbstractContact {
//empty fields class
}

class AbstractContact {
private Object contactId;

public Object getContactId() { return this.contactId }

public void setContactId(Object contactId) {this.contactId = contactId}
}


AbstractContact class is placed in external library.

I'm using PodamFactory with my DataProvider which extending AsbractRandomDataProviderStrategy for filling PersonJob. But when JAXB serializes it I git such error:

java.lang.ClassCastException: java.lang.Object incompatible with org.w3c.dom.Element

Is there a way to switch off instantiation of contactId field for AbstractContact class through DataProvider which extending AsbractRandomDataProviderStrategy?

Answer

First of all, can you change contactId to an actual type? I bet during runtime it's not an Object, but as it's declared it confuses Podam.

If the former is not an option, then you can do three things:

  1. Exclude contactId field with @PodamExclude annotation
  2. Exclude contactId field with a class info strategy

    DefaultClassInfoStrategy classInfoStrategy = DefaultClassInfoStrategy.getInstance(); classInfoStrategy.addExcludedField(PersonAddress.class, "contactId"); podamFactory.setClassStrategy(classInfoStrategy);

  3. Simply call pojo.setContactId(null); after manufacturing or even better pojo.setContactId(yourActualAddressObject);
