Tuomas Toivonen :
When I hit the database with PagingAndSortingRepository.findAll(Pageable) I get Page<ObjectEntity>. However, I want to expose DTO's to the client and not entities. I can create DTO just by injecting entity into it's constructor, but how do I map the entities in Page object to DTO's? According to spring documentation, Page provides read-only operations.
Also, Page.map is not possibility, as we don't have support for java 8. How to create the new Page with mapped objects manually?
Ali Dehghani :
You can still use the Page.map without lambda expressions:
Page<ObjectEntity> entities = objectEntityRepository.findAll(pageable);
Page<ObjectDto> dtoPage = entities.map(new Converter<ObjectEntity, ObjectDto>() {
@Override
public ObjectDto convert(ObjectEntity entity) {
ObjectDto dto = new ObjectDto();
// Conversion logic
return dto;
}
});
