代码如下：

import com.spire.doc.*;
import com.spire.doc.documents.*;

public class MultiLevelList {
    public static void main(String[] args) {
        //创建一个Document类的实例
        Document document = new Document();
        //添加Section
        Section sec = document.addSection();

        //添加段落
        Paragraph paragraph = sec.addParagraph();
        paragraph.appendText("Lists");
        paragraph.applyStyle(BuiltinStyle.Title);
        paragraph = sec.addParagraph();
        paragraph.appendText("Numbered List: ").getCharacterFormat().setBold(true);

        //创建编号列表样式
        ListStyle numberList = new ListStyle(document, ListType.Numbered);//编号列表
        numberList.setName("numberList");
        numberList.getLevels().get(1).setNumberPrefix("\u0000.");
        numberList.getLevels().get(1).setPatternType(ListPatternType.Arabic);
        numberList.getLevels().get(2).setNumberPrefix("\u0000.\u0001.");
        numberList.getLevels().get(2).setPatternType(ListPatternType.Arabic);

        //创建符号列表样式
        ListStyle bulletList= new ListStyle(document, ListType.Bulleted);//符号列表
        bulletList.setName("bulletList");

        //添加列表样式
        document.getListStyles().add(numberList);
        document.getListStyles().add(bulletList);

        //添加段落并应用列表样式
        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 1");
        paragraph.getListFormat().applyStyle(numberList.getName());

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2");
        paragraph.getListFormat().applyStyle(numberList.getName());

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.1");
        paragraph.getListFormat().applyStyle(numberList.getName());
        paragraph.getListFormat().setListLevelNumber(1);

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.2");
        paragraph.getListFormat().applyStyle(numberList.getName());
        paragraph.getListFormat().setListLevelNumber(1);

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.2.1");
        paragraph.getListFormat().applyStyle(numberList.getName());
        paragraph.getListFormat().setListLevelNumber(2);
        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.2.2");
        paragraph.getListFormat().applyStyle(numberList.getName());
        paragraph.getListFormat().setListLevelNumber(2);
        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.2.3");
        paragraph.getListFormat().applyStyle(numberList.getName());
        paragraph.getListFormat().setListLevelNumber(2);

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.3");
        paragraph.getListFormat().applyStyle(numberList.getName());
        paragraph.getListFormat().setListLevelNumber(1);

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 3");
        paragraph.getListFormat().applyStyle(numberList.getName());

        paragraph = sec.addParagraph();
        paragraph.appendText("Bulleted List:").getCharacterFormat().setBold(true);

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 1");
        paragraph.getListFormat().applyStyle(bulletList.getName());
        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2");
        paragraph.getListFormat().applyStyle(bulletList.getName());

        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.1");
        paragraph.getListFormat().applyStyle(bulletList.getName());
        paragraph.getListFormat().setListLevelNumber(1);
        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 2.2");
        paragraph.getListFormat().applyStyle(bulletList.getName());
        paragraph.getListFormat().setListLevelNumber(1);
        paragraph = sec.addParagraph();
        paragraph.appendText("List Item 3");
        paragraph.getListFormat().applyStyle(bulletList.getName());

        //保存文档
        document.saveToFile("MultiLevelList.docx", FileFormat.Docx);
        document.dispose();
    }
}
