pageResponse

@JsonIgnoreProperties(ignoreUnknown = true, value = {"pageable"})
public class PageResponse<T> extends PageImpl<T> {

    public PageResponse(@JsonProperty("content") List<T> content, @JsonProperty("page") int page,
                        @JsonProperty("size") int size, @JsonProperty("totalElements") long totalElements) {
        super(content, PageRequest.of(page, size), totalElements);
    }

    public PageResponse(Page<T> page) {
        super(page.getContent(), page.getPageable(), page.getTotalElements());
    }

    public PageResponse(List<T> content, Pageable pageable, long totalElements) {
        super(content, pageable, totalElements);
    }

}

 

 

Service 캐시 적용

    @Cacheable(key = "#page", value = "allGoods", condition = "#page == 0", cacheManager = "cacheManager")
    public Page<GoodsListResponseDto> allGoods(int page, int size, String sortBy, boolean isAsc) {
      ...
        return new PageResponse<>(goodsResponseList, pageable, goodsPage.getTotalElements());
    }
