1、int pageNumber = pageable.getPageNumber() + 1;
int size = pageable.getPageSize();
//总条数
int totalRows = list.size();

    if (pageNumber * size < totalRows) {// 判断是否为最后一页result = list.subList((pageNumber - 1) * size, pageNumber * size);} else {result = list.subList((pageNumber - 1) * size, totalRows);}QueryWithPageDTO resultDto = new QueryWithPageDTO();resultDto.setList(result);resultDto.setTotal(Long.valueOf(totalRows + ""));

2、
public class QueryWithPageDTO {

// 总条数
private Long total;
// 数据
private List<T> list; //FirstPlanDTOpublic Long getTotal() {return total;
}public void setTotal(Long total) {this.total = total;
}public List<T> getList() {return list;
}public void setList(List<T> list) {this.list = list;
}

}
