如何将linkedHashMap转化为实体对象
import lombok.Data; import java.util.List; @Data public class ProfitPage<T> { private int pageSize ; //页码 private int total; //总条数 private Integer size; //当前页 private int pageNo;//页码 private List<T> detail; public ProfitPage(int total){ this.total = total; } /** * 获取总页数 * @return */ public int getTotalPages() { int totalPages = total / Constants.PROFIT_BATCH_NUM; if(total % pageSize != 0){ totalPages++; } return totalPages; } }
detail是ProfitPage对象;
ProfitPage对象是通过JsonString转换过来的
Gson gson = new GsonBuilder().enableComplexMapKeySerialization().create(); String jsonString = gson.toJson(detail.getDetail()); List<VbillCardProfitBean> vbillQrcodeProfitBeans = gson.fromJson(jsonString,List.class);
在这里并没有将list集合转换为List<vbillQrcodeProfitBeans>,还需要将遍历一遍 if(vbillQrcodeProfitBeans!=null&&vbillQrcodeProfitBeans.size()>0){ for (Object vbillCardProfitBeanLinked: vbillQrcodeProfitBeans ) { String vbillCardProfitBeanStr = gson.toJson(vbillCardProfitBeanLinked); VbillCardProfitBean vbillCardProfitBean = gson.fromJson(vbillCardProfitBeanStr,VbillCardProfitBean.class); } } }
