Apache POI Word - 字体和对齐

本章介绍如何使用 Java 在 Word 文档中应用不同的字体样式和对齐方式。通常，字体样式包含:字体大小、类型、粗体、斜体和下划线。对齐方式分为左对齐、居中对齐、右对齐和两端对齐。

字体样式

以下代码用于设置不同样式的字体 −

import java.io.File;
import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.VerticalAlign;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public class FontStyle {

   public static void main(String[] args)throws Exception {

        //空白文档
        XWPFDocument document = new XWPFDocument();
        
        //将文档写入文件系统
        FileOutputStream out = new FileOutputStream(new File("fontstyle.docx"));
        
        //创建段落
        XWPFParagraph passage = document.createParagraph();
        
        //设置粗体和斜体
        XWPFRun passageOneRunOne = passage.createRun();
        passageOneRunOne.setBold(true);
        passageOneRunOne.setItalic(true);
        passageOneRunOne.setText("字体样式");
        passageOneRunOne.addBreak();
        
        //设置文本位置
        XWPFRun passageOneRunTwo = passage.createRun();
        passageOneRunTwo.setText("字体样式二");
        passageOneRunTwo.setTextPosition(100);
        
        //设置删除线、字体大小和下标
        XWPFRun paragraphOneRunThree = paragraph.createRun();
        paragraphOneRunThree.setStrike(true);
        paragraphOneRunThree.setFontSize(20);
        paragraphOneRunThree.setSubscript(VerticalAlign.SUBSCRIPT);
        paragraphOneRunThree.setText(" Different Font Styles");
        
        document.write(out);
        out.close();
        System.out.println("fontstyle.docx written successully");
   }
}

将上述代码保存为 FontStyle.java，然后编译并从命令提示符执行它，如下所示 −

$javac FontStyle.java
$java FontStyle

它将在当前目录中生成一个名为 fontstyle.docx 的 Word 文件，并在命令提示符上显示以下输出 −

fontstyle.docx 写入成功

fontstyle.docx 文件如下所示。

对齐

以下代码用于设置段落文本的对齐方式 −

import java.io.File;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.ParagraphAlignment;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public class AlignParagraph {

   public static void main(String[] args)throws Exception {

        //空白文档
        XWPFDocument document = new XWPFDocument();
        
        //将文档写入文件系统
        FileOutputStream out = new FileOutputStream(
        new File("alignparagraph.docx"));
        
        //创建段落
        XWPFParagraph passage = document.createParagraph();
        
        //将段落对齐方式设置为右对齐
        paragraph.setAlignment(ParagraphAlignment.RIGHT);
        XWPFRun run = paragraph.createRun();
        run.setText("At tutorialspoint.com, we strive hard to " +
         "provide quality tutorials for self-learning " +
         "purpose in the domains of Academics, Information " +
         "Technology, Management and Computer Programming " +
         "Languages.");
        
        //创建另一个段落
        paragraph = document.createParagraph();
        
        //将段落对齐方式设置为居中
      	paragraph.setAlignment(ParagraphAlignment.CENTER);
      	run = paragraph.createRun();
      	run.setText("The endeavour started by Mohtashim, an AMU " +
         "alumni, who is the founder and the managing director " +
         "of Tutorials Point (I) Pvt. Ltd. He came up with the " +
         "website tutorialspoint.com in year 2006 with the help" +
         "of handpicked freelancers, with an array of tutorials" +
         " for computer programming languages. ");
			
      document.write(out);
      out.close();
      System.out.println("alignparagraph.docx 写入成功");
   }
}

将上述代码保存为 AlignParagraph.java，然后从命令提示符中编译并执行它，如下所示 −

$javac AlignParagraph.java
$java AlignParagraph

它将在当前目录中生成一个名为 alignparagraph.docx 的 Word 文件，并在命令提示符中显示以下输出 −

alignparagraph.docx 写入成功

alignparagraph.docx 文件如下所示 −
