pot-tl动态遍历

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

• 具体代码：

  @Data
  public class WordVO {
      private List<PictureRenderData> picture;
  
      private String problem;
  
      private String reason;
  }
  

  @RestController
  public class TestController {
  
    @GetMapping("/download")
    public void download() throws IOException {
        Map<String, Object> map = new HashMap<String, Object>();
        InputStream inputStream = Thread.currentThread().getContextClassLoader()
                .getResourceAsStream("template/test.docx");
        ListRenderPolicy policy = new ListRenderPolicy();
        Configure config = Configure.newBuilder()
                .bind("pictures", policy).build();
        List<WordVO> detailList = new ArrayList<>();
        WordVO one = new WordVO();
        WordVO two = new WordVO();
        one.setProblem("问题测试1");
        two.setProblem("问题测试2");
        one.setReason("原因测试1");
        two.setReason("原因测试2");
        List<PictureRenderData> pList1 = new ArrayList<>();
        List<PictureRenderData> pList2 = new ArrayList<>();
        pList1.add(new PictureRenderData(100, 120, "C:/Users/gp/Desktop/1.jpg"));
        pList1.add(new PictureRenderData(100, 120, "C:/Users/gp/Desktop/2.jpg"));
        pList2.add(new PictureRenderData(100, 120, "C:/Users/gp/Desktop/1.jpg"));
        one.setPicture(pList1);
        two.setPicture(pList2);
        detailList.add(one);
        detailList.add(two);
        List<Object> list = new ArrayList<>();
        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("C:/Users/gp/Desktop/测试.docx");
    }
  }
  

• word模板
  

• 导出结果
