在本章中，您将学习如何使用 Java 编程为段落应用边框。

In this chapter, you will learn how to apply border to a paragraph using Java programming.

Applying Border

以下代码用于在文档中应用边框 −

The following code is used to apply Borders in a Document −

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

public class ApplyingBorder {

   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("applyingborder.docx"));

      //create paragraph
      XWPFParagraph paragraph = document.createParagraph();

      //Set bottom border to paragraph
      paragraph.setBorderBottom(Borders.BASIC_BLACK_DASHES);

      //Set left border to paragraph
      paragraph.setBorderLeft(Borders.BASIC_BLACK_DASHES);

      //Set right border to paragraph
      paragraph.setBorderRight(Borders.BASIC_BLACK_DASHES);

      //Set top border to paragraph
      paragraph.setBorderTop(Borders.BASIC_BLACK_DASHES);

      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.");

      document.write(out);
      out.close();
      System.out.println("applyingborder.docx written successully");
   }
}

将上述代码保存在名为 ApplyingBorder.java, 的文件中，并从命令提示符按以下方式编译并执行它 −

Save the above code in a file named ApplyingBorder.java, compile and execute it from the command prompt as follows −

$javac ApplyingBorder.java
$java ApplyingBorder

如果您的系统已配置 POI 库，那么它将编译并执行，在当前目录中生成一个名为 applyingborder.docx 的 Word 文档，并显示以下输出 −

If your system is configured with the POI library, then it will compile and execute to generate a Word document named applyingborder.docx in your current directory and display the following output −

applyingborder.docx written successfully

applyingborder.docx 文件看起来如下 −

The applyingborder.docx file looks as follows −
