使用docx4j+docx4j-ImportXHTML实现将html转成word

1.依赖

复制代码

        <!--docx4j + docx4j-ImportXHTML实现html转word -->
        <dependency>
            <groupId>org.docx4j</groupId>
            <artifactId>docx4j</artifactId>

        </dependency>

2.测试代码

前置条件：

复制代码
String htmlContent = pdfService.generateHtmlContent();
这个是得到填充后的模板的内容！！！

复制代码

            String htmlContent = pdfService.generateHtmlContent();

            XHTMLImporterImpl xhtmlImporter = new XHTMLImporterImpl(wordPackage);
            mainDocumentPart.getContent().addAll(xhtmlImporter.convert(htmlContent, null));

            // 将 Word 文档写入 ByteArrayOutputStream
            ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
            wordPackage.save(outputStream);

        } catch (Exception e) {

            return new ResponseEntity<>(HttpStatus.INTERNAL_SERVER_ERROR);
        }
    }
