JAVA 导出 word

1、模板方式导出

1.1、引入 maven 依赖

<dependency><groupId>com.deepoove</groupId><artifactId>poi-tl</artifactId><version>1.12.2</version>
</dependency>

1.2、导出文档代码

public static void main(String[] args) {Map<String, Object> dataMap = new HashMap<>(16);dataMap.put("title", "标题内容");String pic1 = "C:\\Users\\HARRIS\\Desktop\\打工人.jpg";dataMap.put("pic1", pic1);dataMap.put("productCategory", Texts.of("超链接").link("http://www.baidu.com.cn").create());dataMap.put("attachRealName", Texts.of("锚点文本").anchor("custNo").create());List<Student> students = new ArrayList<>(10);students.add(new Student("张三", 18, 23.5, "111"));students.add(new Student("李四", 18, 23.5, "111"));students.add(new Student("王五", 24, 23.5, "111"));students.add(new Student("马六", 24, 23.5, "111"));List<String[]> dataList = new ArrayList<>();for (Student item : students) {dataList.add(new String[]{item.getName(), String.valueOf(item.getAge()), String.valueOf(item.getScore()),item.getPrice()});}// 创建一个列表来存储行数据RowRenderData commonTitle = Rows.of("姓名", "年龄","分数", "price").textColor("FFFFFF").bgColor("4472C4").center().create();List<RowRenderData> rows = new ArrayList<>();// 添加表头rows.add(commonTitle);// 遍历数据集合，创建 RowRenderData 对象并添加到列表中for (String[] data : dataList) {RowRenderData row = Rows.of(data).textFontFamily("仿宋_GB2312").textFontSize(9).horizontalCenter().center().create();rows.add(row);}TableRenderData table = Tables.create(rows.toArray(new RowRenderData[0]));RowRenderData totalRow = Rows.of("合计", "", "", "80%").horizontalCenter().center().create();table.addRow(totalRow);MergeCellRule.MergeCellRuleBuilder builder = MergeCellRule.builder();int[] indexArr = new int[]{1};for (int i : indexArr) {for (int j = 0; j < dataList.size() / 2; j++) {// 纵向合并单元格builder.map(MergeCellRule.Grid.of(j * 2 + 1, i), MergeCellRule.Grid.of(j * 2 + 2, i));}}// 横向合并单元格  MergeCellRule.Grid.of(x轴下标，y轴下标)builder.map(MergeCellRule.Grid.of(table.getRows().size() - 1, 0), MergeCellRule.Grid.of(table.getRows().size() - 1, 2));MergeCellRule rule = builder.build();table.setMergeRule(rule);dataMap.put("table1", table);try {//模板路径String filePath =  "C:\\Users\\HARRIS\\Desktop\\testTemplate.docx";String url = "C:\\Users\\HARRIS\\Desktop\\out.docx";if (!new File(url).getParentFile().exists()) {boolean mkdir = new File(url).getParentFile().mkdirs();if (mkdir) {System.out.printf("创建%s目录%n", new File(url).getParentFile());}}//解析模板XWPFTemplate template = XWPFTemplate.compile(filePath);//渲染数据template.render(dataMap);//以文件形式输出template.writeAndClose(Files.newOutputStream(Paths.get(url)));} catch (Exception e) {throw new RuntimeException(e);}}
