### 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)][poi-3.14-20160307.jar]**

### 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)
