EasyExcel通过模板导出数据

大家好，这两天在做excel导出功能，使用的是easyExcel，不得不说其功能全面，很好入手。
但是在开发的过程中也会遇到一些文档里无法提供解决的问题，这里我分享代码，方便以后自己观看，也希望能帮到想要导出功能的童鞋。

注: 大家好，今天更新内容：eastExcel 使用模板下载，本地正常下载，但是发布到服务器上遇到一个一些问题，
目前抽空在看看解决方法，再最下面贴出来希望有大佬看到能指点一二，小弟在这里先谢过了。
我又换了一个方法去实现通过模板下载excel功能

    <dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>2.2.0-beta1</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency>

@Overridepublic void exportInfo(List<CustomerInfo> customerDealerInfo, HttpServletResponse response) throws IOException {OutputStream out = null;BufferedOutputStream bos = null;try {String templateFileName = FileUtil.getPath() + "templates" + File.separator + "模板.xls";response.setContentType("application/vnd.ms-excel");response.setCharacterEncoding("utf-8");String fileName = URLEncoder.encode("下载后的名称.xls", "utf-8");response.setHeader("Content-disposition", "attachment; filename=" + new String(fileName.getBytes("UTF-8"), "ISO-8859-1"));out = response.getOutputStream();bos = new BufferedOutputStream(out);//读取ExcelExcelWriter excelWriter = EasyExcel.write(bos).withTemplate(templateFileName).build();WriteSheet writeSheet = EasyExcel.writerSheet().build();//customerDealerInfo 是我查询并需导出的数据，并且里面的字段和excel需要导出的字段对应// 直接写入Excel数据excelWriter.fill(customerDealerInfo, writeSheet);excelWriter.finish();bos.flush();} catch (Exception e) {// 重置responseresponse.reset();response.setContentType("application/json");response.setCharacterEncoding("utf-8");Map<String, String> map = new HashMap<String, String>(16);map.put("status", "failure");map.put("message", "下载文件失败" + e.getMessage());response.getWriter().println(JSON.toJSONString(map));}}

public class FileUtil {public static InputStream getResourcesFileInputStream(String fileName) {return Thread.currentThread().getContextClassLoader().getResourceAsStream("" + fileName);}public static String getPath() {return FileUtil.class.getResource("/").getPath();}public static File createNewFile(String pathName) {File file = new File(getPath() + pathName);if (file.exists()) {file.delete();} else {if (!file.getParentFile().exists()) {file.getParentFile().mkdirs();}}return file;}public static File readFile(String pathName) {return new File(getPath() + pathName);}
}

我查询并需导出的数据，并且里面的字段和excel需要导出的字段对应

       这里是报错行：ExcelWriter excelWriter = EasyExcel.write(bos).withTemplate(templateFileName).build();
