项目使用的是jeecg开源框架(springmvc+spring+hibernate+。。。。。。等)此代码仅供参考!如有更好的意见或建议可留言。 创建excel大致分这几步: 1、创建HSSFWorkbook对象(也就是excel文档对象) 2、通过HSSFWorkbook对象创建sheet对象(也就是excel中的sheet) 3、通过sheet对象创建HSSFROW对象(row行对象) 4、通过HSSFROW对象创建列cell并set值(列名) controller 层 /** * excel自定义导出 * @param hAqscTieupsummary * @param request * @param response * @param dataGrid * @param modelMap * @return */ @SuppressWarnings("deprecation") @RequestMapping(params = "exportEXL") public String exportEXL(HAqscTieupsummaryEntity hAqscTieupsummary, HttpServletRequest request, HttpServletResponse response, DataGrid dataGrid, ModelMap

Why is detailTextLabel not visible?

一笑奈何 提交于 2019-11-28 06:41:27
detailTextLabel is not visible (code below). Can you tell me why? // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... NSString *cellValue = [myListArray objectAtIndex:indexPath.row]; cell.textLabel.text

Fullcalendar: Change the color for specific days

你离开我真会死。 提交于 2019-11-28 06:29:45
I'm stuck with a project I get at work. I need to change the background color of some days. It's a calendar where the user should see, which days are available and which not. I found out that there is an attribute called "data-date", but I didn't found a possibility to use it. Is there any way to manipulate the background of specific days? I think there must be a way, cause the cell which shows the current date has another color too. Regin Larsen For the views month , basicWeek and basicDay you can change the rendering of the days by providing a dayRender function. E.g.: $("#calendar")

深度学习之长短期记忆网络LSTM理解

转自博客 http://colah.github.io/posts/2015-08-Understanding-LSTMs/ ,大致翻译了一下,大神讲的很好。 RNN Networks 人类不会每时每刻都开始思考。当你阅读这篇文章时,你会根据你对之前单词的理解来理解每个单词。你不会扔掉所有东西,然后再从头开始思考。你的思想有持久性。 传统的神经网络无法做到这一点,这似乎是一个主要的缺点。例如, 目前还不清楚传统的神经网络如何利用其对电影中先前事件的推理来为后来的事件提供信息。 循环神经网络解决了这个问题。它们是带有循环的网络,允许信息持续存在。 递归神经网络具有循环。 在上图中,一块神经网络A,接受一些输入 并输出值 。循环允许信息从网络的一个步骤传递到下一个步骤。 这些循环使得循环神经网络看起来有点神秘。但是,如果你多想一点,事实证明它们与普通的神经网络并没有什么不同。可以将循环神经网络视为同一网络的多个副本,每个副本都将消息传递给后继者。考虑如果我们展开循环会发生什么: 展开的递归神经网络。 这种类似链的性质表明,递归神经网络与序列和列表密切相关。它们是用于此类数据的神经网络的自然架构。 他们肯定会被使用!在过去几年中,将RNN应用于各种问题取得了令人难以置信的成功:语音识别,语言建模,翻译,图像字幕......这个列表还在继续。我将讨论使用RNNs可以实现的惊人壮举

HBase学习之路 (六)过滤器

目录 过滤器(Filter) HBase过滤器的分类 比较过滤器 专用过滤器 正文 回到顶部 过滤器(Filter)   基础API中的查询操作在面对大量数据的时候是非常苍白的,这里Hbase提供了高级的查询方法:Filter。Filter可以根据簇、列、版本等更多的条件来对数据进行过滤,基于Hbase本身提供的三维有序(主键有序、列有序、版本有序),这些Filter可以高效的完成查询过滤的任务。带有Filter条件的RPC查询请求会把Filter分发到各个RegionServer,是一个服务器端(Server-side)的过滤器,这样也可以降低网络传输的压力。   要完成一个过滤的操作,至少需要两个参数。 一个是抽象的操作符 ,Hbase提供了枚举类型的变量来表示这些抽象的操作符:LESS/LESS_OR_EQUAL/EQUAL/NOT_EUQAL等; 另外一个就是具体的比较器(Comparator) ,代表具体的比较逻辑,如果可以提高字节级的比较、字符串级的比较等。有了这两个参数,我们就可以清晰的定义筛选的条件,过滤数据。 抽象操作符(比较运算符) LESS < LESS_OR_EQUAL <= EQUAL = NOT_EQUAL <> GREATER_OR_EQUAL >= GREATER > NO_OP 排除所有 比较器(指定比较机制) BinaryComparator

(Easy) Game of Life leetCode

☆樱花仙子☆ 提交于 2019-11-28 05:25:50
Description: According to the Wikipedia's article : "The Game of Life , also known simply as Life , is a cellular automaton devised by the British mathematician John Horton Conway in 1970." Given a board with m by n cells, each cell has an initial state live (1) or dead (0). Each cell interacts with its eight neighbors (horizontal, vertical, diagonal) using the following four rules (taken from the above Wikipedia article): Any live cell with fewer than two live neighbors dies, as if caused by under-population. Any live cell with two or three live neighbors lives on to the next generation. Any

NSTableView: detecting a mouse click together with the row and column

心已入冬 提交于 2019-11-28 04:44:26
I'm trying to detect when a mouse click occurs in an NSTableView, and when it does, to determine the row and column of the cell that was clicked. So far I've tried to use NSTableViewSelectionDidChangeNotification, but there are two problems: It only triggers when the selection changes, whereas I want every mouse click, even if it is on the currently selected row. The clickedRow and clickedColumn properties of NSTableView are both -1 when my delegate is called. Is there a better (and correct) way of doing this?

WPF Datagrid cell, cellinfo and selectedcells + custom selection

核能气质少年 提交于 2019-11-28 04:29:18
问题 I want to manipulate selection in WPF datagrid, but I have problem with access to actual cells and setting focus on them and marking them as selected. Can anyone explain me: Why there isn't some simple way to get the **DatagridCell** from **DatagridCellInfo**? Why is almost nobody on SO working with WPF datagrids? (I don't see much Q/A with votes up) Is there an easy way how to make your own selection mode for WPF datagrid? What's my problem I wanted to make custom selection on WPF Datagrid
