进行测试：

		System.out.println(page.getBeginIndex());
		System.out.println(page.getCurrentPage());
		System.out.println(page.getEveryPage());
		System.out.println(page.getTotalCount());
		System.out.println(page.getTotalPage());
		System.out.println(page.isHasNextPage());
		System.out.println(page.isHasPrePage());
