Spire.Doc for Java 是一款專業的Java Word組件，開發人員使用它可以輕松地將Word文檔創建、讀取、編輯、轉換和打印等功能集成到自己的Java應用程序中。

本文介紹使用Spire.Doc for Java在Word文檔中添加多級項目符號列表和多級編號列表的方法。可點擊此處下載最新版測試。

代碼如下：

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

public class MultiLevelList {
    public static void main(String[] args) {
        //創建一個Document類的實例
        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);

        //創建編號列表樣式
        ListStyle numberList = new ListStyle(document, ListType.Numbered);//編號列表
        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);

        //創建符號列表樣式
        ListStyle bulletList= new ListStyle(document, ListType.Bulleted);//符號列表
        bulletList.setName("bulletList");

        //添加列表樣式
        document.getListStyles().add(numberList);
        document.getListStyles().add(bulletList);

        //添加段落并應用列表樣式
        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());

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