Skip field globally in ModelMapper

Question

I am using ModelMApper to map objects from DTO to Impl - when deserializing the object. This is done in combination with JAxRS. When user makes a POST/PUT request I dont want the "id" to ever be mapped.

I need to skip the "id" field for all the mappings. I dont want to do this one by one since there aren't necessarily explicit maps for all classes. How could I configure the mapper to skip all "id" fields from all DTOs to Impls mappings.

Thank you

One approach is to use Conditions to conditionally map (or not) id properties. Something like this (not tested):

Condition skipIds = new Condition() {
    public boolean applies(MappingContext<Object, Object> context) {
        return !context.getMapping().getLastDestinationProperty().getName().equals("id");
    }
};

modelMapper.getConfiguration().setPropertyCondition(skipIds);

This sets the skipIds condition to be used globally for all properties, so that the mapping of values to any destination property with the name "id" will be skipped.

Using this doesn't seem to prevent `Unmapped destination properties found` errors when executing `modelMapper.validate()` – Casey Mar 27 '17 at 08:50

@Jonathan 's solution worked for me with a slight modification. I had to change

public boolean applies(MappingContext<S, D> context)

to

public boolean applies(MappingContext context)
