刚刚安装了 POI 3.8 jar 并更改了代码...我收到此错误：

 public static void setStyleDataFormat( CellStyle style, int formatType )
{
    switch( formatType )
    {
        case CELL_TYPE_PERCENTAGE:

            style.setDataFormat(DataFormat.getFormat("0%"));
            break;

        case CELL_TYPE_PERCENTAGE_TWO_DECIMAL_PLACES:

            style.setDataFormat(DataFormat.getFormat("0.00%"));
            break;

        case CELL_TYPE_NUMERIC:

            style.setDataFormat(DataFormat.getFormat("#,##0"));
            break;

        case CELL_TYPE_NUMERIC_TWO_DECIMAL_PLACES:

            style.setDataFormat(DataFormat.getFormat("#,##0.00"));
            break;

        case CELL_TYPE_DATE:
        case CELL_TYPE_DATE_EMPTY_ON_ERROR:

            style.setDataFormat(DataFormat.getFormat("m/d/yy"));
            break;

        case CELL_TYPE_CURRENCY:

            style.setDataFormat(DataFormat.getFormat("($#,##0.00);($#,##0.00)"));
            break;

        case CELL_TYPE_CURRENCY_NO_CENTS:

            style.setDataFormat(DataFormat.getFormat("($#,##0_);($#,##0)"));
            break;
    }
}

不能从静态上下文引用非静态方法 getFormat(java.lang.String)

non static method cannot be referenced from static context should be able to help you fix this. It seems that Apache decided you shouldn't be so static.

DataFormat是一个接口，因此您不能在其上调用方法，就好像它们是静态的一样

您的代码应该类似于

   // Do this once per workbook
   DataFormat format = wb.createDataFormat();

   .....

   // Use the object in your per-cell work
   for (Cell c : row) {
       CellStyle cs = c.getCellStyle();
       cs.setDataFormat(format.get("dd/mm/yyyy");
   }
