如题！
望大虾解答！
以下是我的代码：



@SuppressWarnings("unchecked")

	public PageModel<Book> findByTypeName(int pageNo, int pageSize,

			String typename) {

		String sql = "select * from ("

			+ " select *,row_number() over(order by pubtime) rownum "

			+ " from new_book  where typename = ?) temp "

			+ " where rownum between ? and ?";

		

		List<Book> all = new ArrayList<Book>();

		PageModel<Book> pageModel = new PageModel<Book>();

		

		int counts = this.getTotalRecords("select count(1) from new_book where typename = " + typename);

		

		if(counts <=0) {

			return null;

		} else {

			pageModel.setTotalRecords(counts);

			pageModel.setTotalPages();

			pageModel.setPageNo(pageNo);

			

			int start = pageModel.getPageSize()*(pageModel.getPageNo()-1) + 1;

			int end = pageModel.getPageSize()*pageModel.getPageNo();

			

			all = getJdbcTemplate().queryForList(sql, new Object[] {typename ,start, end});



System.out.println(sql + " " + start + " " + end + " " + typename + " " + counts);			

System.out.println("List 大小：" + all.size());

			

			pageModel.setList(all);

			

			return pageModel;

		}

	}
