#592 Fix Decorator-support for component model 'spring' and 'jsr330', extend decorator integration-tests, add examples to @DecoratedWith javadoc

  * A typical decorator implementation will be an abstract class and only implement/override a subset of the methods of
  * the mapper type which it decorates. All methods not implemented or overridden by the decorator will be implemented by
- * the code generator.
+ * the code generator by delegating to the generated mapper implementation.
+ * <p>
+ * <b>NOTE:</b> The usage of decorated mappers differs depending on the selected component model.
+ * <p>
+ * <b>NOTE:</b> This annotation is not supported for the component model {@code cdi}. Use CDI's own
+ * <a href="https://docs.jboss.org/cdi/spec/1.0/html/decorators.html">{@code @Decorator}</a> feature instead.
+ * <p>
+ * <b>NOTE:</b> The decorator feature when used with component model {@code jsr330} is considered <em>experimental</em>
+ * and it may change in future releases.
+ * <p>
+ * <h2>Examples</h2>
+ * <p>
+ * For the examples below, consider the following mapper declaration:
+ *
+ * <pre>
+ * &#64;Mapper(componentModel = "...")
+ * &#64;DecoratedWith(PersonMapperDecorator.class)
+ * public interface PersonMapper {
+ *
+ *     &#64;Mapping(target = "name", ignore = true)
+ *     PersonDto personToPersonDto(Person person);
+ *
+ *     AddressDto addressToAddressDto(Address address); // not touched by the decorator
+ * }
+ * </pre>
+ *
+ * <h3>1. Component model 'default'</h3>
+ * <h4>Referencing the original mapper in the decorator</h4>
  * <p>
  * If a constructor with a single parameter accepting the type of the decorated mapper is present, a delegate with
  * generated implementations of all the mapper methods will be passed to this constructor. A typical implementation will
- * store the passed delegate in a field of the decorator and make use of it in the decorator methods.
+ * store the passed delegate in a field of the decorator and make use of it in the decorator methods:
+ *
+ * <pre>
+ * public abstract class PersonMapperDecorator implements PersonMapper {
+ *
+ *     private PersonMapper delegate;
+ *
+ *     public PersonMapperDecorator(PersonMapper delegate) {
+ *         this.delegate = delegate;
+ *     }
+ *
+ *     &#64;Override
+ *     public PersonDto personToPersonDto(Person person) {
+ *         PersonDto dto = delegate.personToPersonDto( person );
+ *         dto.setName( person.getFirstName() + " " + person.getLastName() );
+ *
+ *         return dto;
+ *     }
+ * }
+ * </pre>
+ *
+ * <h4>Using the decorated mapper</h4>
+ * <p>
+ * Nothing special needs to be done. When using {@code Mappers.getMapper( PersonMapper.class )}, the <em>decorator</em>
+ * is returned, with the injected original mapper.
+ * <h3>2. Component model 'spring'</h3>
+ * <h4>Referencing the original mapper in the decorator</h4>
+ * <p>
+ * The generated implementation of the original mapper is annotated with the Spring's {@code @Qualifier("delegate")}. To
+ * autowire that bean in your decorator, add that qualifier annotation as well:
+ *
+ * <pre>
+ * public abstract class PersonMapperDecorator implements PersonMapper {
+ *
+ *     &#64;Autowired
+ *     &#64;Qualifier("delegate")
+ *     private PersonMapper delegate;
+ *
+ *     &#64;Override
+ *     public PersonDto personToPersonDto(Person person) {
+ *         PersonDto dto = delegate.personToPersonDto( person );
+ *         dto.setName( person.getFirstName() + " " + person.getLastName() );
+ *
+ *         return dto;
+ *     }
+ * }
+ * </pre>
+ *
+ * <h4>Using the decorated mapper in the decorator</h4>
+ * <p>
+ * The generated class that extends the decorator is annotated with Spring's {@code @Primary} annotation. To autowire
+ * the decorated mapper in the application, nothing special needs to be done:
+ *
+ * <pre>
+ * &#64;Autowired
+ * private PersonMapper personMapper; // injects the decorator, with the injected original mapper
+ * </pre>
+ *
+ * <h3>3. Component model 'jsr330'</h3>
+ * <h4>Referencing the original mapper</h4>
+ * <p>
+ * JSR 330 doesn't specify qualifiers and only allows to specifically name the beans. Hence, the generated
+ * implementation of the original mapper is annotated with the {@code @Named("fully-qualified-name-of-generated-impl")}.
+ * To inject that bean in your decorator, add the same annotation to the delegate field:
+ *
+ * <pre>
+ * public abstract class PersonMapperDecorator implements PersonMapper {
+ *
+ *     &#64;Inject
+ *     &#64;Named("org.examples.PersonMapperImpl_")
+ *     private PersonMapper delegate;
+ *
+ *     &#64;Override
+ *     public PersonDto personToPersonDto(Person person) {
+ *         PersonDto dto = delegate.personToPersonDto( person );
+ *         dto.setName( person.getFirstName() + " " + person.getLastName() );
+ *
+ *         return dto;
+ *     }
+ * }
+ * </pre>
+ *
+ * <h4>Using the decorated mapper in the decorator</h4>
+ * <p>
+ * Unlike with the other component models, the usage site must be aware if a mapper is decorated or not, as for
+ * decorated mappers, the parameterless {@code @Named} annotation must be added to select the <em>decorator</em> to be
+ * injected:
+ *
+ * <pre>
+ * &#64;Inject
+ * &#64;Named
+ * private PersonMapper personMapper; // injects the decorator, with the injected original mapper
+ * </pre>
  * <p>
- * <b>NOTE:</b> The decorator feature is considered experimental and it may change in future releases. Currently
- * decorators are only supported for the default component model, not for the CDI and Spring models.
