java 功能中，有一个功能是大家经常做的，就是excel导出，简单的excel导出 可以直接用阿里的easyExcel添加注解自动导出来某些固定字段就行了，这个是比较简单的导出，本文就不作过多赘述
这篇文章主要是针对，某些页面的导出，比如说按照页面上的表格的样式导出数据 类似于下面图片这样的，主要应用于报表，自定义的样式之类的excel导出 本文导出 总汇，标品，定开三个sheet的数据，有则导出，无则不用导出
导出的excel需要的pom结构
最后导出的请求接口字段 
最后导出的内容如下
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>easyexcel</artifactId>
<version>3.2.1</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>ooxml-schemas</artifactId>
<version>1.4</version>
</dependency>
1 第一步 控制层
文章来源：https://www.toymoban.com/news/detail-699085.html
/**
* 根据报价单id导出报表
*
* @param response
* @param id
*/
@PostMapping("/exportPriceDetail/{id}")
@ApiOperation(value = "根据报价单id导出报表")
@SneakyThrows
public void exportPriceDetail(HttpServletResponse response, @PathVariable("id") Long id, @RequestBody List<ExportMenuReq> menus) {
response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
response.setCharacterEncoding("utf-8");
String encodeFileName = URLEncoder.encode("报价单", "UTF-8").replaceAll("\\+", "%20");
response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + encodeFileName + ".xlsx");
response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");
priceDetailExportService.exportPriceDetail(response, id,menus);
}2.第二步 逻辑层
主要生成水印和处理要导出的，模块的逻辑
文章来源地址https://www.toymoban.com/news/detail-699085.html
@SneakyThrows
public void exportPriceDetail(HttpServletResponse response, Long id, List<ExportMenuReq> menus) {
UserDTO user = AuthenticationContext.getUser();
Watermark watermark = new Watermark();
watermark.setContent(user.getUserAccount()+"@XX集团"+user.getErpId());
watermark.setWidth(500);
watermark.setHeight(200);
watermark.setYAxis(200);
ExcelWriter excelWriter = EasyExcel.write(response.getOutputStream()).inMemory(true).registerWriteHandler(new CustomerWaterMarkHandler(watermark)).build();
List<String> sheetNames = new ArrayList<>();
Map<String, List<String>> openContentColumnNames = new HashMap<>();
Map<String, List<String>> openContentDevelopmentColumnNames = new HashMap<>();
for (ExportMenuReq menu : menus) {
sheetNames.add(menu.getName());
if (CollectionUtils.isNotEmpty(menu.getChildren())) {
List<String> columnNames = openContentColumnNames.get(menu.getName()) != null ? openContentColumnNames.get(menu.getName()) : new ArrayList<String>();
List<ExportMenuReq> openContents = menu.getChildren();
for (ExportMenuReq openContent : openContents) {
if (Constants.DEVELOPMENT_INFO.equals(openContent.getName()) && CollectionUtils.isNotEmpty(openContent.getChildren())) {
List<ExportMenuReq> developmentColumns = openContent.getChildren();
List<String> developmentColumnNames = developmentColumns.stream().map(tree -> tree.getName() + Constants.DEVELOPMENT_SUFFIX).collect(Collectors.toList());
columnNames.addAll(developmentColumnNames);
openContentDevelopmentColumnNames.put(menu.getName(), developmentColumnNames);
} else {
columnNames.add(openContent.getName());
}
}
//根据ID获取列，如果用名称遇到名称一样的数据，就会因为key一样导致只有一个列表，并且两个列表value都放入一个key
openContentColumnNames.put(menu.getId().toString(), columnNames);
}
}
exportPriceDetail(id, sheetNames, openContentColumnNames, openContentDevelopmentColumnNames, excelWriter);
