1.简介
我们在上一章介绍了如果想实现将markdown内容转换为word的话, 如果想要转换后的word内容排版好看的话, 就需要将其转换过程分为两步
markdown→htmlhtml→ooXML(Office Open XML) word内容,word元信息本身就是个xml)
上一章节我们使用Flexmark将markdown内容转换为html内容, 完成了第一步, 本章节我们将介绍如何将html转换为ooxml
2. 环境信息
为了兼容更多的场景, 所以并没有用一些高版本的SDK, 信息如下
Java: 8
Docx4j: 8.3.10
3. Maven

public static void main(String[] args) {
String html = "<html><head></head><body><h2>嘉文四世</h2>\n" + "<blockquote>\n" + "<p>德玛西亚</p>\n" + "</blockquote>\n" + "<p><strong>给我找些更强的敌人！</strong></p>\n" + "<table>\n" + "<thead>\n" + "<tr><th>列1</th><th>列2</th></tr>\n" + "</thead>\n" + "<tbody>\n" + "<tr><td>数据1</td><td>数据2</td></tr>\n" + "</tbody>\n" + "</table>\n" + "</body></html>";
convertHtmlToDocx(html, "demo.docx");
}
}
测试结果如下:
在根目录生成了docx文件, 文件内容如下
生成的文档内容是有样式的, 只不过像字体样式, 包括表格都是默认样式
但如果项目上要求输出的制式文档或者是模板文件, 对文字标题甚至是表格都有其样式要求的话, 那就得用一些高阶用法了
5. 自定义样式
如果想要自定义输出的内容样式, 其实就两个思路:
- 从输出的内容出发: 毕竟是html转的ooxml, 那么可以给html添加css样式给docx4j进行渲染, 但前提是一些简单的css样式
- 从word出发: word文件本身就有内置样式并且也可以自定义样式, 所以可以先在模板文件中定义好样式, 然后和输入的内容进行映射
5.1 Html添加Css
比如给表格添加样式, 让表格有边框并且有一定的样式,css样式如下:
table{border-collapse:collapse;border-spacing:0;width:100%;margin:1em 0;background-color:transparent;}table th{background-color:#f7f7f7;border:1px solid #ddd;padding:8px 12px;text-align:left}table td{border:1px solid #ddd;padding:8px 12px}
public static void main(String[] args) {
String html = "<html><head><style>table{border-collapse:collapse;border-spacing:0;width:100%;margin:1em 0;background-color:transparent;}table th{background-color:#f7f7f7;border:1px solid #ddd;padding:8px 12px;text-align:left}table td{border:1px solid #ddd;padding:8px 12px}</style></head><body><h2>嘉文四世</h2>\n" + "<blockquote>\n" + "<p>德玛西亚</p>\n" + "</blockquote>\n" + "<p><strong>给我找些更强的敌人！</strong></p>\n" + "<table>\n" + "<thead>\n" + "<tr><th>列1</th><th>列2</th></tr>\n" + "</thead>\n" + "<tbody>\n" + "<tr><td>数据1</td><td>数据2</td></tr>\n" + "</tbody>\n" + "</table>\n" + "</body></html>";
convertHtmlToDocx(html, "demo.docx");
}
测试结果如下:
此时其实如果想要输出的内容样式好看, 通过定义css基本可以满足了, 但如果是制式文档对行间距,字间距,字体型号,标题,等有严格的要求, 如果这些都通过css定义的话 有点麻烦, 毕竟人家制式的文档本身已经定义好了, 那么就可以使用下面的方式
5.2 Html映射WordStyleId
我们可以先看一下word的内置样式, 我这里使用的是MAC office,Windows 和 wps 有些许差异
从上图中可以看到, word其实是有很多内置样式的, 并且可以新建样式, 下面也可以筛选列表
我们经常在快捷样式列表中选择的样式其实就是从这里来的
我们先手动新增一个自定义的样式 如下:
然后通过docx4j获取所有的wordstyle列表 如下:
private static WordprocessingMLPackage wordMLPackage;
@BeforeAll
@SneakyThrows
public static void init_mainDocumentPart() {
File templateFile = new File("demo.docx");
wordMLPackage = WordprocessingMLPackage.load(templateFile);
}
@Test
@SneakyThrows
public void given_doc_template_when_extract_style_then_return_style_list() {
final StyleDefinitionsPart sdp = wordMLPackage.getMainDocumentPart().getStyleDefinitionsPart();
List<Style> styles = sdp.getContents().getStyle();
log.info("docx styles length: {}", styles.size());
for (Style style : styles) {
String styleId = style.getStyleId();
String name = style.getName().getVal();
final String type = style.getType();
log.info("styleId: {}, name: {}, type: {}", styleId, name, type);
}
}
测试结果如下: 除了内置的样式如一级标题id=1, 最后的两个自定义样式是我们新加的
为什么手动添加了一个, 而出现两个样式记录: 可能是在选在样式类型的时候选择的是“链接段落和字符”导致出现了一对多的情况
[main] INFO html2docx.DocxStyleTest -- docx styles length: 25
[main] INFO html2docx.DocxStyleTest -- styleId: a, name: Normal, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: 1, name: headhttp://www.devze.coming 1, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: 2, name: heading 2, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: 3, name: heading 3, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: 4, name: heading 4, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: a0, name: Default Paragraph Font, type: character[main] INFO html2docx.DocxStyleTest -- styleId: a1, name: Normal Table, type: table[main] INFO html2docx.DocxStyleTest -- styleId: a2, name: No List, type: numbering[main] INFO html2docx.DocxStyleTest -- styleId: a3, name: header, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: a4, name: 页眉 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: 10, name: 标题 1 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: 20, name: 标题 2 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: 30, name: 标题 3 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: 40, name: 标题 4 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: a5, name: Normal Indent, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: a6, name: Subtitle, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: a7, name: 副标题 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: a8, name: Title, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: a9, name: 标题 字符, type: character[main] INFO html2docx.DocxStyleTest -- styleId: aa, name: Emphasis, type: character[main] INFO html2docx.DocxStyleTest -- styleId: ab, name: Hyperlink, type: character[main] INFO html2docx.DocxStyleTest -- styleId: ac, name: Table Grid, type: table[main] INFO html2docx.DocxStyleTest -- styleId: ad, name: caption, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: customBodyText, name: customBodyText, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: customBodyText0, name: customBodyText 字符, type: character
测试的时候发现一个奇怪的问题, 如果没有手动添加样式的话输出的内容如下:
[main] INFO html2docx.DocxStyleTest -- docx styles length: 22
[main] INFO html2docx.DocxStyleTest -- styleId: Normal, name: Normal, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: Heading1, name: heading 1, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: Heading2, name: heading 2, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: Heading3, name: heading 3, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: Heading4, name: heading 4, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: DefaultParagraphFont, name: Default Paragraph Font, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Header, name: header, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: HeaderChar, name: Header Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Heading1Char, name: Heading 1 Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Heading2Char, name: Heading 2 Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Heading3Char, name: Heading 3 Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Heading4Char, name: Heading 4 Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: NormalIndent, name: Normal Indent, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: Subtitle, name: Subtitle, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: SubtitleChar, name: Subtitle Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Title, name: Title, type: paragraph[main] INFO html2docx.DocxStyleTest -- styleId: TitleChar, name: Title Char, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Emphasis, name: Emphasis, type: character[main] INFO html2docx.DocxStyleTest -- styleId: Hyperlink, name: Hyperlink, type: character[main] INFO html2docx.DocxStyleTest -- styleId: TableGrid, name: Table Grid, type: table[main] INFO html2docx.DocxStyleTest -- styleId: TableNormal, name: Normal Table, type: table[main] INFO html2docx.DocxStyleTest -- styleId: Caption, name: caption, type: paragraph
可以发现内置的style前后不一致,未添加自定义样式前一级标题的id为“Heading1”, 修改后就成了“1”, 可能是默认生成的文档还是英文的, 当修改保存了之后, 就被系统篡改成中文的了
ok, word样式我们定义好了
现在就通过docx4j应用一下自定义的word样式, 实现思路: 通过html标签的class属性 映射wrod的styleId
首先给html加上class信息如下图:
private static WordprocessingMLPackage wordMLPackage;
@BeforeAll
@SneakyThrows
public static void init_mainDocumentPart() {
File templateFile = new File("demo.docx");
wordMLPackage = WordprocessingMLPackage.load(templateFile);
}
@Test
@SneakyThrows
public void given_doc_template_and_class_when_mapping_custom_style_then_render_doc() {
final String html = "<html><head><style>table{border-collapse:collapse;border-spacing:0;width:100%;margin:1em 0;background-color:transparent}table th{background-color:#f7f7f7;border:1px solid#ddd;padding:8px 12px;text-align:left}table td{border:1px solid#ddd;padding:8px 12px}</style></head><body><h2 class=\"1\">嘉文四世</h2><blockquote><p class=\"customBodyText\">德玛西亚</p></blockquote><p class=\"customBodyText\"><strong>给我找些更强的敌人！</strong></p><table><thead><tr><th>列1</th><th>列2</th></tr></thead><tbody><tr><td>数据1</td><td>数据2</td></tr></tbody></table></body></html>";
final MainDocumentPart mainDocumentPart = wordMLPackage.getMainDocumentPart();
XHTMLImporterImpl importer = new XHTMLImporterImpl(wordMLPackage);
// CLASS_TO_STYLE_ONLY：只认 class，不管 style 和 <strong>/<em> 等标签，相当于「纯 CSS 类驱动样式」
// CLASS_PLUS_OTHER：class 是基础样式，style 和内联标签是补充 / 覆盖，相当于「类样式 + 局部微调样式」
// IGNORE_CLASS: 忽略class样式
importer.setParagraphFormatting(FormattingOption.CLASS_TO_STYLE_ONLY);
importer.setRunFormatting(FormattingOption.CLASS_TO_STYLE_ONLY);
importer.setTableFormatting(FormattingOption.CLASS_TO_STYLE_ONLY);
// html转ooxml
final List<Object> docxContent = importer.convert(html, null);
final List<Object> docxOldContent = mainDocumentPart.getContent();
// 清空模板内容 并 添加新的内容
docxOldContent.clear();
docxOldContent.addAll(docxContent);
Docx4J.save(wordMLPackage, new File("newDemo.docx"), Docx4J.FLAG_NONE);
}
测试结果如下:
一级标题和自定义样式都映射完成了
6. 占位符替换
结合上述的功能, 已经能很好的输出html到word中了, 但项目上又有新的需求了, 不光是将markdown→html→word, 还需要将大模型识别到的内容一同输出到模板文件中去, 也就是最终输出的内容有两部分
- 大模型提取到的人员信息, 如姓名工作住址等
- 大模型总结的人员描述信息(markdown)
其实第二步内容使用doc4j已经实现了, 现在需要通过占位符的方式输出人员基本信息到word中, 这个其实很好处理, 可以使用poi-tl实现占位符的替换
6.1 Maven
<dependency> <groupId>com.deepoove</groupId> <artifactId>poi-tl</artifactId> <version>1.12.0</version> </dependency>
6.2 实现
@Test
public void given_template_doc_and_content_when_replace_then_replace() {
final Configure templateEngineConfigure = Configure.builder().build();
File templateFile = new File("demo.docx");
File outputFile = new File("newDemo.docx");
Map<String, Object> data = new HashMap<>();
data.put("user", "嘉文四世");
data.put("summoner", "张铁牛");
data.put("position", "打野");
data.put("dialogue", "给我找些更强的敌人");
try (XWPFTemplate template = XWPFTemplate.compile(templateFile, templateEngineConfigure)) {
template.render(data).writeToFile(outputFile.getAbsolutePath());
}
catch (IOException e) {
log.error("failed to replace template word placeholder", e);
throw new RuntimeException(e);
}
}
模板内容如下:
测试结果如下:
不仅实现了占位符的替换, 而且也保留了占位符本身的样式, 这就很舒服了
7. 封装工具类
为了更方便的调用docx4j和poi-tl操作word, 我们可以封装一个工具类去更方便的调用, 比如可以通过传入一个map对象然后实现自动替换占位符和markdown内容渲染, 最好是通过链式调用一行代码就解决战斗, 没错 它来了

9. 小结
本章使用docx4j和poi-tl实现将普通占位符内容和html文本内容转换为word, 并介绍了如何使用其特性实现自定义样式渲染, 最后封装链式调用的工具类和对应的单元测试代码, 结合上一章内容能够将各种形式的内容通过一行代码即可实现word的渲染
到此这篇关于Java实现将html转换为word(docx)的文章就介绍到这了,更多相关Java html转word内容请搜索编程客栈(www.devze.com)以前的文章或继续浏览下面的相关文章希望大家以后多多支持编程客栈(www.devze.com)！
