Java生成Word文档

1. Apache POI

简介:
Apache POI 是一个用于读写Microsoft Office文件格式的开源Java库，它支持多种Office文件格式，包括Word (.doc 和 .docx)。

依赖:
在 pom.xml 文件中添加 Apache POI 的依赖：

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>5.2.1</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>5.2.1</version>
</dependency>

简单用法:

import org.apache.poi.xwpf.usermodel.*;

import java.io.FileOutputStream;
import java.io.IOException;

public class SimpleWordGenerator {
   
    public static void main(String[] args) {
   
        try (XWPFDocument document = new XWPFDocument()) {
   
            XWPFParagraph paragraph = document.createParagraph();
            XWPFRun run = paragraph.createRun();
            run.setText("Hello, World!");

            FileOutputStream fileOut = new FileOutputStream("simple.docx");
            document.write(fileOut);
            fileOut.close();
        } catch (IOException e) {
   
            e.printStackTrace();
        }
    }
}

复杂用法:

import org.apache.poi.xwpf.usermodel.*;

import java.io.FileOutputStream;
import java.io.IOException;

public class ComplexWordGenerator {
   
    public static void main(String[] args) {
   
        try (XWPFDocument document = new XWPFDocument()) {
   
            // 创建标题
            XWPFParagraph titlePara = document.createParagraph();
            XWPFRun titleRun = titlePara.createRun();
            titleRun.setText("Report Title");
            titleRun.setBold(true);
            titlePara.setAlignment(ParagraphAlignment.CENTER);

            // 创建列表
            XWPFParagraph listPara = document.createParagraph();
            XWPFRun listRun = listPara.createRun();
            listPara.createRun().setText("Item 1");
            listPara.createRun().addBreak(BreakType.LINE);
            listPara.createRun().setText("Item 2");
            listPara.createRun().addBreak(BreakType.LINE);
            listPara.createRun().setText("Item 3");

            // 创建表格
            XWPFTable table = document.createTable(3, 2);
            table.getRow(0).getCell(0).setText("Header 1");
            table.getRow(0).getCell(1).setText("Header 2");
            table.getRow(1).getCell(
