导出word并且插入图片

	// 导出报告 Word文档（仅导出单个Word文件）@GetMapping("/exportReportWord")@ApiOperationSupport(order = 8)@ApiOperation(value = "导出报告 Word 文档", notes = "正式节点才能导出报告")public void exportReportWord(@RequestParam String yearMonth, HttpServletResponse response) {try {// 5. 生成Word文档并直接输出到响应流String fileName = UUID.randomUUID() + ".docx";response.setContentType("application/vnd.openxmlformats-officedocument.wordprocessingml.document");response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "UTF-8"));try (XWPFTemplate template = getXwpfTemplate(null)) {template.write(response.getOutputStream());}} catch (Exception e) {log.error("导出Word失败", e);try {response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, "导出失败：" + e.getMessage());} catch (IOException ex) {log.error("设置响应错误信息失败", ex);}}}private XWPFTemplate getXwpfTemplate(CmComplaintVO cmComplaintVO) throws IOException {Map<String, Object> map = new HashMap<>();// 1. 处理文本参数（保持原有逻辑）map.put("work_order_time",Optional.ofNullable(LocalDateTime.now()).map(time -> time.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))).orElse(null));// 处理图片的核心代码Resource imageResource = new ClassPathResource("templates/statistic_chart.png");try (InputStream imageStream = imageResource.getInputStream()) {// 1. 将输入流转换为 BufferedImage（直接从流转换，避免中间字节数组）BufferedImage bufferedImage = ImageIO.read(imageStream);if (bufferedImage == null) {throw new IOException("无法解析图片流，可能是图片格式不支持");}// 2. 使用 Pictures.ofBufferedImage() 创建图片对象PictureRenderData pictureData = Pictures.ofBufferedImage(bufferedImage, PictureType.PNG).size(712, 500) // 设置图片宽高（像素）.create(); // 创建 PictureRenderDatamap.put("image", pictureData); // 绑定到模板占位符 {{image}}} catch (IOException e) {log.error("处理图片失败", e);// 可选：添加默认图片或抛出友好异常throw new RuntimeException("导出Word失败：图片处理异常", e);}// 3. 编译模板（必须绑定图片渲染策略）PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();Resource templateResource = resolver.getResource("classpath:/templates/cm_statistics.docx");Configure config = Configure.builder().bind("image", new PictureRenderPolicy()) // 绑定图片渲染策略.build();XWPFTemplate template = XWPFTemplate.compile(templateResource.getInputStream(), config).render(map);return template;}

本文介绍了导出报告Word文档的实现方法。通过Spring Boot的@GetMapping注解创建"/exportReportWord"接口，使用XWPFTemplate工具生成Word文件并直接输出到响应流。方法包含：(1)设置响应头为Word文档类型；(2)调用getXwpTemplate方法处理模板；(3)异常处理机制。模板处理方法getXwpfTemplate包含：文本参数处理（如格式化当前时间）、图片处理（将PNG图片转为BufferedImage并设置尺寸）以及模板编译（绑定图片渲染策略）。该方法最终返回包含动态数据和图片的Word模板对象，支持导出包含统计图表的报告文档。

如果不插图片就简单了

代码如下

/*** 传入 对象  返回生成的word文档* @param cmComplaintVO* @return* @throws IOException*/private XWPFTemplate getXwpfTemplate(CmComplaintVO cmComplaintVO) throws IOException {Map<String, Object> map = new HashMap<>();// 方式1：直接处理map.put("work_order_time",Optional.ofNullable(LocalDateTime.now()).map(time -> time.format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))).orElse(null));// 导出PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();Resource resource = resolver.getResource("classpath:/templates/cm_statistics.docx");
//		Configure config = Configure.builder().bind("table", new LoopRowTableRenderPolicy()).build();
//		XWPFTemplate template = XWPFTemplate.compile(resource.getInputStream(), config).render(map);XWPFTemplate template = XWPFTemplate.compile(resource.getInputStream()).render(map);return template;}
