篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了用jxl导出Excel相关的知识,希望对你有一定的参考价值。

断断续续,终于把这个简单的功能实现了。

本身花的有效时间也不多,但是陆续出现好多蛋疼的问题,归根结底是自己程序功底不深厚,尤其对Java流理解不透彻。

还好今天时间充足,磨得我背疼不已的时候,终于把它整完了。

这里首先介绍下背景:SSM框架(前端easyui)、POI因为乱码问题被pass掉、五一假期又没有花时间,不得不赶紧换个API把他整出来。

功能大致是这样的:

busiAccept.jsp中引入common.jsp主要是为了busiAccept.js在请求后台的时候带过去必要的参数:loginId(在session中)、请求地址(在配置文件中)

pom.xml

1 <!-- 导出Excel -->
2         <dependency>
3             <groupId>net.sourceforge.jexcelapi</groupId>
4             <artifactId>jxl</artifactId>
5             <version>2.6.12</version>
6         </dependency>

另外这个pom导入jar包也很奇怪,明明是http://220.181.85.249:8081/nexus/index.html#welcome里边先找到jxl然后把代码版本信息等拷进来。但是往往这样都只能找到低版本,反而要去网上搜索jxl+maven,找到引入高版本的那种jar的pom代码帖进来,进而会直接下载高版本jar

另外BusiAcceptServiceImpl.java中,

 92                 bWorkbook.close();
 94                 os.flush();
 95                 os.close();
流的关闭顺序不对会导致导出空白的Excel。
另外用封装的请求方式$u.webutil.doPost("../../../AWCCI", info, true, registClient);为什么不行(到底行不行)还有待测试,老火的是家里外网速度太慢。

技术分享

点击导出之后,浏览器会自动下载Excel文件到浏览器的下载目录。

再回味一下关键代码:

 15         WritableWorkbook bWorkbook = null;
 26             // 创建Excel对象  
 27             //根据传进来的file对象创建可写入的Excel工作薄  
 28             OutputStream os = response.getOutputStream();  
 29             bWorkbook = Workbook.createWorkbook(os);
bWorkbook.write();

对于流,还需要熟悉……
