经常会遇到给用户提供数据下载的场景，将相关数据导出为Excel，因此对此进行了相关工具方法的封装：
pom:

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>3.9</version>
        </dependency>

Controller层调用：

    @GetMapping("download")
    public void downloadAnnualBudget(@RequestParam("businessYear") Integer year,
                                       @RequestParam(value = "version", required = false) Integer version,
                                       HttpServletResponse httpResponse) {
        // 获取待下载数据
        List<AnnualBudgetDownLoadBo> dataset = annualBudgetService.getBudget(year, version);
        String[] headers = {"资源类型", "单价", "折扣", "预算量", 计费量"};
        download(annualBudgetDownLoadBos, headers, httpResponse);
    }

工具类封装：

public class ExportExcelUtils<T> {

    private static final Logger logger = LoggerFactory.getLogger(ExportExcelUtils.class);

    /**
     * 导出无头部标题行Excel, 时间格式默认：yyyy-MM-dd hh:mm:ss
     * @param workbook
     * @param title
     * @param dataset
     */
    public static <T> void exportExcel(XSSFWorkbook workbook, String title, Collection<T> dataset) {
        exportExcel2007(workbook,title, null, dataset);
    }

    /**
     * 导出带头部标题行Excel, 时间格式默认：yyyy-MM-dd hh:mm:ss
     * @param workbook
     * @param title
     * @param headers
     * @param dataset
     */
    public static <T> void exportExcel(XSSFWorkbook workbook, String title, String[] headers, Collection<T> dataset) {
        exportExcel2007(workbook,title, headers, dataset);
    }

    /**
