将文档转换为 JSON 表示的 Docx4j 功能？

Question

有没有好的方法可以将文档转换成 JSON 表示形式，然后显示在网页上？（要求文档转为JSON）

如果没有内置的方法，我的想法是将 Run/Paragraph 结构表示为 JSON 对象，但我觉得一旦我这样做就不会起作用开始处理更复杂的 Word 文档。

如果您添加：

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
    <version>2.11.3</version>
</dependency>

您可以尝试类似的方法：

import org.docx4j.Docx4J;
import org.docx4j.openpackaging.packages.WordprocessingMLPackage;

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

public class ConvertOutJSON  {

    static String inputfilepath = System.getProperty("user.dir") + "/sample-docs/sample-docxv2.docx";

    public static void main(String[] args)
            throws Exception {
        
        
        WordprocessingMLPackage wordMLPackage 
            = Docx4J.load(new java.io.File(inputfilepath));


        String xml = wordMLPackage.getMainDocumentPart().getXML();

        //System.out.println(xml);

        XmlMapper xmlMapper = new XmlMapper();
        JsonNode node = xmlMapper.readTree(xml);

        ObjectMapper jsonMapper = new ObjectMapper();
        //String json = jsonMapper.writeValueAsString(node);
        String json = jsonMapper.writerWithDefaultPrettyPrinter().writeValueAsString(node);

        System.out.println(json);

    }    
}

但是在快速测试中，我注意到一些 w:p 节点没有作为 JSON 发出。我没有查看它们是否在 readTree 步骤或 ObjectMapper 写入其输出时被 Jackson 丢弃；你需要深入研究 Jackson 来解决这个问题。

它当前正在生成如下输出：
