代码实现

public class PoitlTest {

    public static void main(String[] args) throws IOException {
        test();
    }

    private static void test() throws IOException {
        // 创建列表策略
        NumbericRenderPolicy policy = new NumbericRenderPolicy();
        ConfigureBuilder builder = Configure.newBuilder();
        // 为pictures指定列表策略
        builder.bind("pictures", policy).build();

        // 多级列表数据，由于列表中可能是Text或者Picture，所以类型采用RenderData
        List detailList = new ArrayList<>();
        List detailList2 = new ArrayList<>();
        TextRenderData textRenderData1 = new TextRenderData();
        TextRenderData textRenderData2 = new TextRenderData();
        textRenderData1.setText("选项1");
        textRenderData2.setText("选项2");

        BufferedImage bufferedImage1 = ImageIO.read(new URL("https://dev-nfs.sf8cloud.com/receive/EZ-NFS-22a36097-47de-451a-877d-730598ba9166.png"));
        BufferedImage bufferedImage2 = ImageIO.read(new URL("https://dev-nfs.sf8cloud.com/receive/EZ-NFS-c8a9d8fd-9a4b-4376-a44c-00e87030aa71.gif"));

        PictureRenderData pictureRenderData1 = new PictureRenderData(100, 120, ".png",bufferedImage1);
        PictureRenderData pictureRenderData2 = new PictureRenderData(100, 120, ".png",bufferedImage2);
        detailList.add(textRenderData1);
        detailList.add(pictureRenderData1);
        detailList2.add(textRenderData2);
        detailList2.add(pictureRenderData2);

        // 使用NumbericRenderData包装列表数据，这样模板中可以直接使用{{*pictures}}机型渲染;
        NumbericRenderData numbericRenderData1 = new NumbericRenderData(Pair.of(STNumberFormat.DECIMAL, ""),detailList);
        NumbericRenderData numbericRenderData2 = new NumbericRenderData(Pair.of(STNumberFormat.DECIMAL, ""),detailList2);

        TestPoiMain main = new TestPoiMain();
        List> amapList = new ArrayList<>();
        Map bmap = new HashMap(16);
        bmap.put("pictures", numbericRenderData1);
        bmap.put("no", "A");
        bmap.put("content", "这是一个题目");
        amapList.add(bmap);

        Map bmap2 = new HashMap(16);
        bmap2.put("pictures", numbericRenderData2);
        bmap2.put("no", "B");
        bmap2.put("content", "这是第二个个题目");
        amapList.add(bmap2);

        main.setListMap(amapList);

        XWPFTemplate template = XWPFTemplate.compile("D:\\problem.docx", builder.build()).render(main);
        FileOutputStream out = new FileOutputStream("D:\\output.docx");
        template.write(out);
    }
