why DozerConverter is not working?

Question

I am using dozer version 5.5.1. And i want to configure my custom converter so i have this

import org.dozer.DozerConverter;

import com.example.movies.api.models.response.ClientResponseDTO;

public class MyCustomConverter
    extends DozerConverter<ClientResponseDTO, String> {

    public MyCustomConverter() {
        super(ClientResponseDTO.class, String.class);
    }

    @Override
    public String convertTo(ClientResponseDTO source, String destination) {
        return "ClientResponseDTO Converted to string!";
    }

    @Override
    public ClientResponseDTO convertFrom(String source, ClientResponseDTO destination) {
        return new ClientResponseDTO();
    }   

}

Which i am loading with Spring like this:

@Bean
public Mapper dozerBeanMapper() {
    DozerBeanMapper mapper = new DozerBeanMapper();
    List<CustomConverter> converters = new ArrayList<>();
    converters.add(new MyCustomConverter(ClientResponseDTO.class, String.class));
    mapper.setCustomConverters(converters);
    return mapper;
}

Then, i have this usage:

    @Autowired Mapper mapper;
    ...

    ClientResponseDTO clientResponseDTO = clientService.getClient(id);
    String conversion = this.mapper.map(clientResponseDTO, String.class);

And the custom converter is never being called. Do you know why is that ? Regards!

Note that your constructor doesn't need to have parameters: `public PagingDDTransformer() { super(ClientResponseDTO.class, String.class); }` — Philippe Gonday, Apr 10 '15 at 13:00
You are right! i've already changed it. I've updated the post. It still not working — jscherman, Apr 10 '15 at 15:02
The mapper is coming from injection as you said. I am using Spring 4, i am autowiring the bean. — jscherman, Apr 10 '15 at 15:03

Refer to dozer documentation you should add mapping to bean description. Eg.

<bean id="org.dozer.Mapper" class="org.dozer.DozerBeanMapper">
<property name="mappingFiles">
<list>
  <value>systempropertymapping1.xml</value>
  <value>dozerBeanMapping.xml</value>
  <value>injectedCustomConverter.xml</value>
</list>
</property><property name="customConvertersWithId">
<map>
  <entry key="CustomConverterWithId" ref="configurableConverterBeanInstance1" />
  <entry key="CustomConverterWithId2" ref="configurableConverterBeanInstance2" />
</map>
</property>
</bean>
