java如何使用poi-tl在word模板里渲染多张图片

embedded/2024/12/28 11:43:35/

1、poi-tl官网地址
http://deepoove.com/poi-tl/

2、引入poi-tl的依赖

java">	  <dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.12.1</version></dependency>

3、定义word模板

释义：?为开始标签，/为结束标签，@picture为渲染每一个图片
在这里插入图片描述

4、Java测试代码

java">@RequestMapping("/test")
@RestController
public class TestController {private static final String PICTURE_PATH = "D:\\test\\picture\\";@GetMapping("/download")public void download(HttpServletResponse response) throws IOException {//定义存储集合Map<String, Object> pictureMap= new HashMap<>();//创建并得到图片集合,设置图片大小List<Map<String, PictureRenderData>> pictureList = createPictureList(100, 100);pictureMap.put("pictureList", pictureList);//通过XWPFTemplate处理XWPFTemplate document = XWPFTemplate.compile(new ClassPathResource("templates/test.docx").getFile()).render(pictureMap);//返回数据设置setResponseHeader(response);//输出流并关闭OutputStream os = response.getOutputStream();document.write(os);os.close();}private List<Map<String, PictureRenderData>> createPictureList(int width, int height) {List<Map<String, PictureRenderData>> list = new ArrayList<>();//添加多张图片到集合list.add(createPictureMap("Banner (1).jpg", width, height));list.add(createPictureMap("Banner (10).jpg", width, height));list.add(createPictureMap("Banner (100).jpg", width, height));return list;}private Map<String, PictureRenderData> createPictureMap(String pictureName, int width, int height) {Map<String, PictureRenderData> map = new HashMap<>();//创建PictureRenderData对象并设置其大小//Pictures还有其他方法，如Pictures.ofStream()流处理，可根据自己的需求及文档替换map.put("picture", Pictures.ofLocal(PICTURE_PATH + pictureName).size(width, height).create());return map;}private void setResponseHeader(HttpServletResponse response) {response.reset();response.setContentType("application/octet-stream");response.setHeader("Content-disposition","attachment;filename=picture_word_" + System.currentTimeMillis() + ".docx");}
}
