-----------------------------------------
Summary: Dozer custom mapping to skip primitive fields that aren't
set
Key: AIRAVATA-2751
URL: https://issues.apache.org/jira/browse/AIRAVATA-2751
Project: Airavata
Issue Type: Bug
Reporter: Marcus Christie
I'm finding that primitive fields that aren't set on a thrift model, like
{{long}}, are mapped into entities as a 0. The Dozer mapping (see
ObjectMapperSingleton) isn't calling {{isSet}} on the thrift models to make
sure that they are mapped.
Here's some pseudo code that I think would do the trick, although I'm not sure
if a CustomFieldMapper is the right way to customize this in Dozer (seemed like
the best option given the research I did):
{code}
public static ObjectMapperSingleton getInstance(){
if(instance == null) {
instance = new ObjectMapperSingleton();
instance.setCustomFieldMapper(new CustomFieldMapper() {
@Override
public boolean mapField(Object source, Object destination,
Object sourceFieldValue, ClassMap classMap, FieldMap fieldMap) {
if (source instanceof TBase) {
TBase thriftSource = (TBase) source;
// TODO: following doesn't work, needs reflection
srcField =
thriftSource.getClass()._Fields.byName(fieldMap.getSrcFieldName());
if (!thriftSource.isSet(srcField)) {
// Just skipping mapping field if not set on Thrift
source model
return true;
}
}
return false;
}
});
}
return instance;
}
{code}
