Overview

This PR Support for CollectionMappingStrategy on the @BeanMapping and @Mapping. This allows for more granular control over the collection mapping strategy at the individual method or property level, rather than relying solely on the global configuration set for the entire mapper.

Key Changes

• @BeanMapping Support:
  • A collectionMappingStrategy has been added to the @BeanMapping annotation interface.
  • The annotation processor now reads this strategy and applies it as the default for all property mappings within the method, unless overridden by a more specific @Mapping annotation.
• @Mapping Support:
  • A collectionMappingStrategy member has been added to the @Mapping annotation interface.
  • The code generation logic has been updated to prioritize the strategy set on a specific @Mapping.

With these changes, we can now flexibly control the strategy for populating target collections for specific use cases, without altering the global mapper configuration.

The resolution priority is as follows: @Mapping > @BeanMapping > @Mapper > @MapperConfig.
