Poi Excel无法应用背景颜色

我正在使用POI来生成excel。 我有一个场景就像我想应用背景到表中的单元格行，但我无法做到这一点，我给了代码below.Please告诉什么是我的代码中的错误，或者是我所做的代码是正确的..

  System.out.println("Called"); try { XSSFWorkbook xb = new XSSFWorkbook(); XSSFSheet sheet = xb.createSheet(sheetName); XSSFCellStyle cellStyle = xb.createCellStyle(); XSSFFont font = xb.createFont();

如果你使用这个片段，它将工作：

 XSSFCellStyle style = workbook.createCellStyle(); XSSFColor myColor = new XSSFColor(Color.RED); style.setFillForegroundColor(myColor); style.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND); 

我可以给你这个链接 ，在那里描述如何使用XSSF。 主要更改是从工作簿中创build一个新的XSSFCellStyle并设置填充模式。
