Use hutool tool class to operate excel with more empty Sheet1

To do a project in the near future, you need to be right excel Read and write , be used hutool Tool class , There are many edited tables sheet The situation of

hutool After operation excel Always bring a default empty sheet1, Study it and share it with you

Official documents say that this solution ：

// Define the table name when initializing 
ExcelWriter writer = new ExcelWriter("d:/aaa.xls", " surface 1");
// Switch sheet, At this point, from 0 OK, start writing 
writer.setSheet(" surface 2");
...
writer.setSheet(" surface 3");
...

It doesn't feel quite in line with my actual situation

		try (ExcelWriter writer = new ExcelWriter(drawConfig.getExcelPath())) {
    
            writer.setSheet(1).renameSheet(" The operation log ")
                    .setColumnWidth(1, 28)
                    .setColumnWidth(3, 28)
                    .write(drawRows, false)
                    .close();
        }catch (IllegalArgumentException e){
    
            ...
        }

After thinking about it, I should use ExcelWriter By default, a sheet1, Here, read first and then write , The problem is solved

		ExcelReader reader;
        try {
    
            reader = ExcelUtil.getReader(drawConfig.getExcelPath());
            ExcelWriter writer = reader.getWriter();
            writer.setSheet(1).renameSheet(" The operation log ")
                    .setColumnWidth(1, 28)
                    .setColumnWidth(3, 28)
                    .write(drawRows, false)
                    .close();
        } catch (POIException e) {
    
            throw new UniException(" file does not exist ！");
        }
