Apache POI Word-有用的资源

Apache POI Word是一种用于读写Microsoft Word文档的Java API。它允许开发人员在Java应用程序中生成、修改和读取Word文档,以及将Word文档转换为其他格式如PDF、HTML等。以下是一些有用的资源,可用于学习和使用Apache POI Word。

文档
代码示例

以下代码示例可以帮助您了解如何使用Apache POI Word创建、修改和读取Word文档。

创建Word文档
import org.apache.poi.xwpf.usermodel.*;

import java.io.*;
import java.math.BigInteger;

public class CreateWordDocument {
    public static void main(String[] args) {
        XWPFDocument document = new XWPFDocument();

        //创建段落
        XWPFParagraph paragraph1 = document.createParagraph();
        paragraph1.setAlignment(ParagraphAlignment.CENTER);

        //在段落中创建文本
        XWPFRun run1 = paragraph1.createRun();
        run1.setBold(true);
        run1.setText("Apache POI Word");
        run1.setFontSize(16);
        run1.addBreak();

        //在段落中创建文本
        XWPFRun run2 = paragraph1.createRun();
        run2.setBold(false);
        run2.setText("Creating a Word document using Apache POI Word");
        run2.setFontSize(12);

        //创建新的段落
        XWPFParagraph paragraph2 = document.createParagraph();

        //通过流创建图片
        try {
            String imagePath = "poi-word.png";
            InputStream inputStream = new FileInputStream(imagePath);
            XWPFRun run3 = paragraph2.createRun();
            run3.addPicture(inputStream, XWPFDocument.PICTURE_TYPE_PNG, imagePath, Units.toEMU(300), Units.toEMU(200));
        } catch (IOException e) {
            e.printStackTrace();
        }

        //保存Word文档
        try {
            FileOutputStream out = new FileOutputStream("Hello.docx");
            document.write(out);
            out.close();
            System.out.println("Word document created successfully!");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
修改Word文档
import org.apache.poi.xwpf.usermodel.*;

import java.io.*;

public class ModifyWordDocument {
    public static void main(String[] args) {
        try {
            FileInputStream file = new FileInputStream(new File("Hello.docx"));
            XWPFDocument document = new XWPFDocument(file);

            //获取所有段落
            for (XWPFParagraph paragraph : document.getParagraphs()) {

                //获取所有文本
                for (XWPFRun run : paragraph.getRuns()) {

                    //设置文本字体
                    run.setFontFamily("Arial");
                    run.setFontSize(12);

                    //在文本中添加加粗
                    if (run.getText(0).contains("Apache")) {
                        run.setBold(true);
                    }
                }
            }

            //获取所有表格
            for (XWPFTable table : document.getTables()) {

                //获取所有行
                for (XWPFTableRow row : table.getRows()) {

                    //获取所有单元格
                    for (XWPFTableCell cell : row.getTableCells()) {

                        //设置单元格边框
                        cell.getCTTc().addNewTcPr().addNewTcBorders().addNewBottom().setVal(STBorder.SINGLE);
                        cell.getCTTc().addNewTcPr().addNewTcBorders().addNewTop().setVal(STBorder.SINGLE);
                        cell.getCTTc().addNewTcPr().addNewTcBorders().addNewLeft().setVal(STBorder.SINGLE);
                        cell.getCTTc().addNewTcPr().addNewTcBorders().addNewRight().setVal(STBorder.SINGLE);

                        //设置单元格背景颜色
                        cell.setColor("FBBF93");
                    }
                }
            }

            //保存Word文档
            FileOutputStream out = new FileOutputStream(new File("Hello.docx"));
            document.write(out);
            out.close();
            System.out.println("Word document modified successfully!");

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
读取Word文档
import org.apache.poi.xwpf.usermodel.*;

import java.io.*;

public class ReadWordDocument {
    public static void main(String[] args) {
        try {
            FileInputStream file = new FileInputStream(new File("Hello.docx"));
            XWPFDocument document = new XWPFDocument(file);

            //获取所有段落
            for (XWPFParagraph paragraph : document.getParagraphs()) {

                //获取所有文本
                System.out.println(paragraph.getText());
            }

            //获取所有表格
            for (XWPFTable table : document.getTables()) {

                //获取所有行
                for (XWPFTableRow row : table.getRows()) {

                    //获取所有单元格
                    for (XWPFTableCell cell : row.getTableCells()) {

                        //获取单元格中的文本
                        System.out.println(cell.getText());
                    }
                }
            }

            file.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
