Java导出Excel文档（poi），并上传到腾讯云对象存储服务器

需求

后台生成周报月报季报年报Excel，将文件下载链接推送给对应客户

开发思路：

1.根据选定日期生成周报，月报，季报，年报数据
2.将这些数据报告生成Excel表格
3.把生成的文件上传到腾讯云对象存储服务器
4.将服务器返回的url存储到数据库

工具

poi-3.14-20160307.jar(点击可下载)

数据

获取数据部分省略了

代码

主方法

public boolean addReportExcelToCloud(ReportResult rr) {OutputStream out = new ByteArrayOutputStream();ExcelProjectUtils eu = new ExcelProjectUtils();eu.exportExcel(rr, out);   //<1>ConvertUtil cu = new ConvertUtil();try {ByteArrayInputStream byteInput = cu.parse(out);String rs = PicUploadToYun.uploadExcel(SysContent.getFileRename("案场数据报.xls"), byteInput);  //<2>addReportExcelToDB(rr, rs);  //<3>return true;} catch (Exception e) {e.printStackTrace();}return false;}

<1> 将数据生成二进制Excel文件 (方法详细见下面代码)
<2> 将生成的二进制文件上传到腾讯云对象存储服务器 (方法详细见下面代码)
<3> 将服务器返回的url存储到数据库 (方法详细见下面代码)
