java按顺序读取docx文件中的内容（包括图片）

使用ApachePOI读取docx文件，首先引入maven:

xml 复制代码

        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi</artifactId>
            <version>5.0.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.poi</groupId>
            <artifactId>poi-ooxml</artifactId>
            <version>5.0.0</version>
        </dependency>

可以对元素进行遍历，获取内容(段落和表格)

如下：

java 复制代码

        try {
            FileInputStream fis = new FileInputStream("xxxx.docx");
            XWPFDocument document = new XWPFDocument(fis);

            // 遍历文档中的所有元素（段落和表格）
            List<IBodyElement> bodyElements = document.getBodyElements();
            for (IBodyElement bodyElement : bodyElements) {
                if (bodyElement instanceof XWPFParagraph) {
                    XWPFParagraph paragraph = (XWPFParagraph) bodyElement;
                    System.out.println(paragraph.getStyleID() + ":" + paragraph.getText());
                } else if (bodyElement instanceof XWPFTable) {
                    System.out.println(((XWPFTable) bodyElement).getText());
                } else if (bodyElement instanceof XWPFPicture) {
                    System.out.println(Arrays.toString(((XWPFPicture) bodyElement).getPictureData().getData()));
                }
            }

            fis.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

发现此遍历方式不能读取到图片，只能通过getAllPictures方法得到所有图片，但失去了段落和图片之间的顺序。经过探索，改正遍历方式：

java 复制代码

            for (IBodyElement element : bodyElements) {
                if (element instanceof XWPFParagraph) {
                    XWPFParagraph paragraph = (XWPFParagraph) element;
                    String text = paragraph.getText();
                    if (text != null && !text.isEmpty()) {
                      //处理段落或正文
                    } else {
                        // 顺序遍历图片
                        paragraph.getIRuns().forEach(run -> {
                            if (run instanceof XWPFRun) {
                                XWPFRun xWPFRun = (XWPFRun) run;
                                for (XWPFPicture picture : xWPFRun.getEmbeddedPictures()) {
                                    XWPFPictureData pictureData = picture.getPictureData();
                                    String base64Image = "<img src='data:image/png;base64," + Base64.getEncoder().encodeToString((pictureData.getData())) + "'/>";       
                                }
                            }
                        });
                    }
                } else if (element instanceof XWPFTable) {
                //处理表格
                    XWPFTable table = (XWPFTable) element;
                    String text = table.getText();
                }
            }

这样遍历就可以按顺序读取docx文件的内容了。
