poi-tl动态遍历

Posted 2022-11-28 听风者-better

最近工作需要导出word文档，选择使用了poi-tl这个word模板引擎
官网文档 Poi-tl Documentation

在使用过程中需要动态遍历一个集合数据，可以使用ListRenderPolicy这个插件，但是官方文档不知为何没有写出具体实例，但是在源码里是可以找到的相应的实例
源码地址

这里我自己写个测试实例以作记录
poi-tl版本

<dependency>
    <groupId>com.deepoove</groupId>
    <artifactId>poi-tl</artifactId>
    <version>1.10.1</version>
</dependency>

          detailList.forEach(wordVO -> 
              list.add(new TextRenderData(wordVO.getProblem()));
              list.add(new TextRenderData(wordVO.getReason()));
              if (CollectionUtils.isNotEmpty(wordVO.getPicture())) 
                  list.addAll(wordVO.getPicture());
              
          );
          map.put("pictures", list);
          XWPFTemplate template = XWPFTemplate.compile(inputStream, config).render(map);
          template.writeToFile(location + "result/test.docx");
