Apache POI Word - 字體樣式和對(duì)齊方式

本章介紹如何使用Java在Word文檔中應(yīng)用不同的字體樣式和對(duì)齊方式。 通常，字體樣式包含:字體大小，類型，粗體，斜體和下劃線。 對(duì)齊分為左，中，右，對(duì)齊。

字體樣式

以下代碼用于設(shè)置不同樣式的字體:

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 
   {
   //Blank Document
   XWPFDocument document= new XWPFDocument(); 
        
   //Write the Document in file system
   FileOutputStream out = new FileOutputStream(
   new File("fontstyle.docx"));
        
   //create paragraph
   XWPFParagraph paragraph = document.createParagraph();
        
   //Set Bold an Italic
   XWPFRun paragraphOneRunOne = paragraph.createRun();
   paragraphOneRunOne.setBold(true);
   paragraphOneRunOne.setItalic(true);
   paragraphOneRunOne.setText("Font Style");
   paragraphOneRunOne.addBreak();
        
   //Set text Position
   XWPFRun paragraphOneRunTwo = paragraph.createRun();
   paragraphOneRunTwo.setText("Font Style two");
   paragraphOneRunTwo.setTextPosition(100);
 
   //Set Strike through and Font Size and Subscript
   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");
   }
}

將上述代碼保存為 FontStyle.java ，然后從命令提示符處編譯并執(zhí)行它，如下所示:

$javac FontStyle.java
$java FontStyle

它將在當(dāng)前目錄中生成名為 font style.docx 的Word文件，并在命令提示符下顯示以下輸出:

fontstyle.docx written successfully

fontstyle.docx 文件如下所示。

對(duì)齊方式

以下代碼用于設(shè)置與段落文本的對(duì)齊方式:

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 
   {
   //Blank Document
   XWPFDocument document= new XWPFDocument(); 
        
   //Write the Document in file system
   FileOutputStream out = new FileOutputStream(
   new File("alignparagraph.docx"));
        
   //create paragraph
   XWPFParagraph paragraph = document.createParagraph();
        
   //Set alignment paragraph to RIGHT
   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.");
        
   //Create Another paragraph
   paragraph=document.createParagraph();
        
   //Set alignment paragraph to CENTER
   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 written successfully");
   }
}

將上述代碼保存為 AlignParagraph.java ，然后從命令提示符處編譯并執(zhí)行，如下所示:

$javac AlignParagraph.java
$java AlignParagraph

它將在當(dāng)前目錄中生成名為 align paragraph.docx 的Word文件，并在命令提示符中顯示以下輸出:

alignparagraph.docx written successfully

alignparagraph.docx 文件如下所示:
