wordxml模版导出

poi-tl是一个基于Apache POI的Word模板引擎，可以使用Word模板和数据创建漂亮的Word文档。下面是一个使用poi-tl进行Word模板导出的示例：

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

import java.io.FileOutputStream;
import java.util.HashMap;
import java.util.Map;

public class WordTemplateExport {
    public static void main(String[] args) throws Exception {
        // 加载Word模板
        XWPFDocument document = new XWPFDocument(WordTemplateExport.class.getResourceAsStream("template.docx"));

        // 获取模板中的段落和表格
        XWPFParagraph paragraph = document.getParagraphs().get(0);
        XWPFTable table = document.getTables().get(0);

        // 替换段落中的占位符
        Map<String, String> placeholders = new HashMap<>();
        placeholders.put("title", "Hi, poi-tl Word模板引擎");
        replacePlaceholder(paragraph, placeholders);

        // 替换表格中的占位符
        Map<String, String> tablePlaceholders = new HashMap<>();
        tablePlaceholders.put("name", "John Doe");
        tablePlaceholders.put("age", "30");
        replacePlaceholder(table, tablePlaceholders);

        // 导出Word文档
        FileOutputStream out = new FileOutputStream("output.docx");
        document.write(out);
        out.close();

        System.out.println("Word模板导出成功！");
    }

    // 替换段落中的占位符
    private static void replacePlaceholder(XWPFParagraph paragraph, Map<String, String> placeholders) {
        List<XWPFRun> runs = paragraph.getRuns();
        for (int i = 0; i < runs.size(); i++) {
            XWPFRun run = runs.get(i);
            String text = run.getText(0);
            if (text != null) {
                for (Map.Entry<String, String> entry : placeholders.entrySet()) {
                    String placeholder = "${" + entry.getKey() + "}";
                    if (text.contains(placeholder)) {
                        text = text.replace(placeholder, entry.getValue());
                        run.setText(text, 0);
                    }
                }
            }
        }
    }

    // 替换表格中的占位符
    private static void replacePlaceholder(XWPFTable table, Map<String, String> placeholders) {
        for (XWPFTableRow row : table.getRows()) {
            for (XWPFTableCell cell : row.getTableCells()) {
                for (XWPFParagraph paragraph : cell.getParagraphs()) {
                    replacePlaceholder(paragraph, placeholders);
                }
            }
        }
    }
}

这个示例中，我们首先加载了一个Word模板文件，然后使用`replacePlaceholder`方法替换模板中的占位符。最后，将替换后的文档导出为一个新的Word文档。
