使用easyPOI根据模板导出

1.导入easypoi依赖

<!-- 导入导出 -->
		<dependency>
			<groupId>cn.afterturn</groupId>
			<artifactId>easypoi-base</artifactId>
			<version>3.0.3</version>
		</dependency>
		<dependency>
			<groupId>cn.afterturn</groupId>
			<artifactId>easypoi-web</artifactId>
			<version>3.0.3</version>
		</dependency>
		<dependency>
			<groupId>cn.afterturn</groupId>
			<artifactId>easypoi-annotation</artifactId>
			<version>3.0.3</version>
		</dependency>

2.设置导出的数据传输对象

@Data
    public class FillData {
        private String name;
        private double number;
    }

3.设置导出的excel模板

4.将模板存放在resource中

5.编写导出的方法

/**
     * 根据模板导出excel
     */
    @Test
    public void test(){
        FillData fillData = new FillData();
        String caseNumber=null;
        if (disEventInfoModel.getCaseNumber()!=null&&!disEventInfoModel.getCaseNumber().equals("")){
            caseNumber = disEventInfoModel.getCaseNumber();
        }
        if (caseNumber==null||caseNumber.equals("")) {
            caseNumber = UUID.randomUUID().toString().replace("-", "");
        }
//        TemplateExportParams params = new TemplateExportParams("exceltemplate/模板.xls");
        TemplateExportParams params = new TemplateExportParams(ExcelExportUtils.convertTemplatePath("exceltemplate/模板.xls"));
        if (params!=null){
            objectToMap(fillData);
            Workbook workbook = ExcelExportUtil.exportExcel(params, objectToMap(fillData));
            export(response, workbook, URLEncoder.encode(caseNumber + ".xls", "UTF-8"));
        }
        // Excel 导出 通过浏览器下载的形式
        public static void export(HttpServletResponse response, Workbook workbook, String fileName) throws IOException {
            response.setHeader("Content-Disposition",
                    "attachment;filename=" + new String(fileName.getBytes("UTF-8"), "iso8859-1"));
            response.setContentType("application/vnd.ms-excel;charset=UTF-8");
            response.setHeader("Pragma", "no-cache");
            response.setHeader("Cache-Control", "no-cache");
            response.setDateHeader("Expires", 0);
            BufferedOutputStream bufferedOutPut = new BufferedOutputStream(response.getOutputStream());
            workbook.write(bufferedOutPut);
            bufferedOutPut.flush();
            bufferedOutPut.close();
        }
