若依框架自定义导出Excel多sheet页+合并单元格(Poi)

在用若依框架是发现自带的导出功能中并不能导出多个sheet和合并单元格,所以我在这里做了修改希望可以帮到你,用到的点个赞呗!

我们先一步步来

整个程序的思路为先返回下载地址,然后根据下载地址去下载excel

一  : 返回下载地址

首先是我们需要excel的下载地址,这里我们直接跳到exportExcel方法,以下是代码部分

其中list,listyw为两个sheet页的数据

@GetMapping("/export")
    public AjaxResult export(BizGuideFileDto bizGuideFile) {
        List list=iBizGuideFileService.selectBizGuideFile(bizGuideFile);
        List listyw=iBizGuideFileService.selectBizGuideFile2(bizGuideFile);        ExcelUtilMerge bizDSubjectExcelUtil = new ExcelUtilMerge(BizGuideFileDto.class);

        return AjaxResult.success(bizDSubjectExcelUtil.exportExcel
                (list,listyw, "sheet1","sheet2","标题据",list.get(0).getFileTitle()));
    }


public AjaxResult exportExcel(List list,List listyw, String sheetName,String sheetName2, String title,String title2)
    {
        this.init(list,listyw, sheetName,sheetName2, title, title2,Type.EXPORT, Excelyw.Type.EXPORT);
        return exportExcel();
    }

1、怎么建立多个sheet页

下面有我附上的工具类可以看到在方法init里面和源码相比多了几条尾号为2的,就是第二个sheet,在建工作簿、获取注解时、获取数据导出时都有相关的2,具体情况可以看代码/

具体逻辑可以从init里面一步步往下看

2、如何合并单元格

exportExcel() --->   
writeSheet() --->  
fillExcelData(index, row) --->
this.addCell(excel, row, vo, field, column++);
先根据这个思路看ExcelUtil

合并的只有三行代码,这里我做了一个判断,因为在这个方法外面是一个for循环,不做判断的话回报多重合并的错误,虽然结果是对的,但是有强迫症的我看着不舒服

这里合并的逻辑为从第三行开始,第listyw.size()+1行结束,第0列开始,第0列结束

if (heBing==true){
                    CellRangeAddress region = new CellRangeAddress(2, (short)listyw.size()+1, 0, (short)0);
                    sheet2.addMergedRegion(region);
                    this.heBing=false;
                }

3、自定义导出字段

因为若依导出是可以自定义的选择导出的字段的,所以只需要给需要导出的字段加上注解就可以,@Excel为若依源码的,是获取第一个sheet的导出字段,@Excelyw是我自己加的获取另一个sheet页导出字段的注解,具体逻辑可以复制Excel的

 @Excel(name = "内容")@Excelyw(name = "内容")
    private String content;
    @Excel(name = "指标")@Excelyw(name = "指标")
    private String kpi;
    

二 :根据下载地址下载excel

@GetMapping("/download")
    public void fileDownload(String fileName, String excelName, HttpServletResponse response, HttpServletRequest request) {
        try {
            if (!FileUtils.checkAllowDownload(fileName)) {
                throw new Exception(StringUtils.format("文件名称({})非法,不允许下载。 ", fileName));
            }
            String realFileName = excelName + fileName.substring(fileName.indexOf("_"));
            String filePath = RuoYiConfig.getDownloadPath() + fileName;
            response.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE);
            // 下载文件名重新编码
            FileUtils.setAttachmentResponseHeader(response, realFileName);
            FileUtils.writeBytes(filePath, response.getOutputStream());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

最后

给你附上exportExcel所在的工具类,具体看相关代码,整个工具类复制就可以用了
