Java从Apache poi获取excel单元格背景颜色

I am trying to get cell color info in .xlsx file using Apache POI.

我试图使用Apache POI在.xlsx文件中获取单元格颜色信息。

Method cellStyle.getFillBackgroundColor() is returning short. How can I convert short to java.awt.Color or any other format(XSSFColor).

方法cellStyle.getFillBackgroundColor()返回short。如何将short转换为java.awt.Color或任何其他格式(XSSFColor)。

Ultimately I want to store the value of cell based on its background color.

最终我想根据背景颜色存储单元格的值。

 Workbook workbook = WorkbookFactory.create(new FileInputStream (new File(SAMPLE_XLSX_FILE_PATH)));
    Sheet sheet = workbook.getSheetAt(0);
    DataFormatter dataFormatter = new DataFormatter();
    sheet.forEach(row -> {
        row.forEach(cell -> {
            String cellValue = dataFormatter.formatCellValue(cell);
            CellStyle cellStyle = cell.getCellStyle();
            System.out.println(cellStyle.getFillBackgroundColor());
            //Color userColor = cellStyle.getFillBackgroundColor(); //ERROR 
        });
        System.out.println();
    });

I am using version 3.6 which I think do not support getFillBackgroundColorColor()

我使用的是版本3.6,我认为不支持getFillBackgroundColorColor()

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>3.6</version>

With .xlsx spreadsheets, you can call the getFillBackgroundColorColor (2 "Color" words) method. It returns an org.apache.poi.ss.usermodel.Color (not a very useful interface), that XSSFColor implements. Then you can cast it as XSSFColor.

使用.xlsx电子表格,您可以调用getFillBackgroundColorColor(2“Color”字样)方法。它返回一个XSSFColor实现的org.apache.poi.ss.usermodel.Color(不是一个非常有用的接口)。然后你可以把它作为XSSFColor。

XSSFColor = (XSSFColor) cellStyle.getFillBackgroundColorColor();

Alternatively, again with .xlxs spreadsheets, you can cast the CellStyle as an XSSFCellStyle, and XSSFCellStyle's getFillBackgroundColorColor method returns an XSSFColor directly. It also has getFillBackgroundXSSFColor which does the same thing.

或者,再次使用.xlxs电子表格,您可以将CellStyle转换为XSSFCellStyle,XSSFCellStyle的getFillBackgroundColorColor方法直接返回XSSFColor。它也有getFillBackgroundXSSFColor,它做同样的事情。

Get the background fill color.

获取背景填充颜色。

Note - many cells are actually filled with a foreground fill, not a background fill - see getFillForegroundColor()

注意 - 许多单元格实际上填充了前景填充,而不是背景填充 - 请参阅getFillForegroundColor()

Beware that solid fills are implemented as foreground colors, so the foreground color may be what you're really after. There are complementary methods for the foreground color, e.g. getFillForegroundColorColor.

请注意,实心填充是作为前景色实现的,因此前景色可能是您真正想要的。前景色有补充方法,例如: getFillForegroundColorColor。
