java实现word文档的参数替换

Java实现Word文档的参数替换可以通过Apache POI库来实现，具体步骤如下：

导入Apache POI库，可以在Maven中添加以下依赖：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>

打开Word文档，读取文档内容，并将需要替换的参数保存到Map中：

FileInputStream inputStream = new FileInputStream(new File("example.docx"));
XWPFDocument document = new XWPFDocument(inputStream);

Map<String, String> params = new HashMap<String, String>();
params.put("name", "张三");
params.put("age", "25");

遍历Word文档中所有的段落和表格，查找需要替换的参数，并进行替换：

for (XWPFParagraph paragraph : document.getParagraphs()) {
    List<XWPFRun> runs = paragraph.getRuns();
    for (XWPFRun run : runs) {
        String text = run.getText(0);
        if (text != null) {
            for (Map.Entry<String, String> entry : params.entrySet()) {
                if (text.contains(entry.getKey())) {
                    text = text.replace(entry.getKey(), entry.getValue());
                    run.setText(text, 0);
                }
            }
        }
    }
}

for (XWPFTable table : document.getTables()) {
    for (XWPFTableRow row : table.getRows()) {
        for (XWPFTableCell cell : row.getTableCells()) {
            for (XWPFParagraph paragraph : cell.getParagraphs()) {
                List<XWPFRun> runs = paragraph.getRuns();
                for (XWPFRun run : runs) {
                    String text = run.getText(0);
                    if (text != null) {
                        for (Map.Entry<String, String> entry : params.entrySet()) {
                            if (text.contains(entry.getKey())) {
                                text = text.replace(entry.getKey(), entry.getValue());
                                run.setText(text, 0);
                            }
                        }
                    }
                }
            }
        }
    }
}

保存并关闭Word文档：

FileOutputStream outputStream = new FileOutputStream(new File("example.docx"));
document.write(outputStream);
outputStream.close();
document.close();

以上就是Java实现Word文档的参数替换的步骤。
