java使用poi-tl模版引擎导出word之列表循环数据渲染

1.模版制作

在静态资源目录下resources/static/templates新建exportWord.docx，编写以下模版内容：

在这里插入图片描述

2.开启spring表达式

（1）引入依赖

<dependency><groupId>org.springframework</groupId><artifactId>spring-expression</artifactId><version>5.3.18</version>
</dependency>

（2）代码中开启表达式

ConfigureBuilder builder = Configure.builder();
// 开启spring表达式
builder.useSpringEL();

3.编写关键代码接口

@GetMapping("/exportWord")
public void exportWord(HttpServletResponse response) throws FileNotFoundException {//存放数据，也就是填充在word里面的值Map<String, Object> params = new HashMap<>();params.put("title","测试使用poi-tl模版导出word");List<Map<String, Object>> list = new ArrayList<>();Map<String, Object> map = new HashMap<>();map.put("a","测试");map.put("b","米");map.put("c","201312");list.add(map);Map<String, Object> map1 = new HashMap<>();map1.put("a","测试2");map1.put("b","千米");map1.put("c","2012312");list.add(map1);params.put("list",list);ConfigureBuilder builder = Configure.builder();// 开启spring表达式builder.useSpringEL();// 或模板在静态资源的相对路径File rootFile = new File((ResourceUtils.getURL("classpath:").getPath()));File templateFile = new File(rootFile, "/static/templates/exportWord.docx");//jar包获取不到文件路径`//URLDecoder.decode() 解决获取中文名称文件路径乱码String templatePath = URLDecoder.decode(templateFile.getPath());//生成文件名String fileName = new SimpleDateFormat("yyyyMMddHHmmss").format(new Date()) + "_" + System.currentTimeMillis();// 导出woldtry {// 导出Word文档为文件XWPFTemplate template = XWPFTemplate.compile(templatePath,builder.build()).render(params);// 将导出的Word文件转换为流response.setContentType("application/octet-stream");response.setHeader("Content-disposition","attachment;filename=\""+fileName+".docx"+"\"");// HttpServletResponse responseOutputStream out = response.getOutputStream();BufferedOutputStream bos = new BufferedOutputStream(out);template.write(bos);bos.flush();out.flush();// 最后不要忘记关闭这些流。PoitlIOUtils.closeQuietlyMulti(template, bos, out);} catch (Exception e) {System.out.println("导出Word文档时出现异常：" + e.getMessage());}
}
