如何将导出项目表结构直接生成Word文档？

本文共计1282个文字，预计阅读时间需要6分钟。

使用Jfinal读取数据库数据并导出到Word文档的代码示例：

javaimport java.io.FileOutputStream;import java.math.BigInteger;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;

public class ExportDataToWord { public static void main(String[] args) { // 假设这里已经获取了数据库连接和数据 List

// 创建Word文档并写入数据 try (FileOutputStream fileOutputStream=new FileOutputStream(output.docx)) { // 代码逻辑省略，这里需要使用Word文档操作库，如Apache POI // 例如：Document document=new Document(); // 文档操作... } catch (Exception e) { e.printStackTrace(); } }

private static List

Map row2=new HashMap(); row2.put(name, 李四); row2.put(age, 25); data.add(row2);

return data; }}
