     * @return 返回值为zip包地址
     * @throws IOException 
     */
    public String exportToExcel(ReportsToExcelParameters reportsToExcelParameters) throws Exception;
    
    /**

     * @param task
     * @param reports
     * @param userdata
     * @param out

Plant as follows

public class ReportsToExcelFactory {
    public final static String EXCEL2003 = "xls";

    public final static String EXCEL2007 = "xlsx";

    public static ReportsToExcel create(String excelType) {
        if (EXCEL2003.equalsIgnoreCase(excelType)) {
            return createReportsToExcel2003();
        }
        else if (EXCEL2007.equalsIgnoreCase(excelType)) {
            return createReportsToExcel2007();
        }
        return null;
    }

    public static ReportsToExcel createReportsToExcel2003() {
        return new ReportsToExcelImplXls();
    }

    public static ReportsToExcel createReportsToExcel2007() {
        return new ReportsToExcelImplXlsx();
    }
}
