Apache Poi Word 简明教程

Apache POI Word - Paragraph

本章您将学习如何创建一个段落以及如何使用 Java 将其添加到文档中。段落是 Word 文件中一页的一部分。

In this chapter you will learn how to create a Paragraph and how to add it to a document using Java. Paragraph is a part of a page in a Word file.

完成本课后，您将能够创建一个段落并在其上执行读取操作。

After completing this chapter, you will be able to create a Paragraph and perform read operations on it.

Create a Paragraph

首先，让我们使用前面章节中讨论的引用类创建一个段落。按照前面一章，首先创建一个文档，然后我们就可以创建一个段落。

First of all, let us create a Paragraph using the referenced classes discussed in the earlier chapters. By following the previous chapter, create a Document first, and then we can create a Paragraph.

以下代码片段用于创建电子表格 −

The following code snippet is used to create a spreadsheet −

//Create Blank document
XWPFDocument document = new XWPFDocument();

//Create a blank spreadsheet
XWPFParagraph paragraph = document.createParagraph();

Run on Paragraph

您可以使用 Run 输入文本或任何对象元素。使用段落实例，您可以创建 run 。

You can enter the text or any object element, using Run. Using Paragraph instance you can create run.

以下代码片段用于创建运行。

The following code snippet is used to create a Run.

XWPFRun run = paragraph.createRun();

Write into a Paragraph

让我们尝试在文档中输入一些文本。请考虑以下文本数据 −

Let us try entering some text into a document. Consider the below text data −

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.

以下代码用于将以上数据写入一个段落。

The following code is used to write the above data into a paragraph.

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

public class CreateParagraph {
   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("createparagraph.docx"));

      //create Paragraph
      XWPFParagraph paragraph = document.createParagraph();
      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("createparagraph.docx written successfully");
   }
}

将以上 Java 代码保存为 CreateParagraph.java, ，然后从命令提示符下编译并运行，如下所示 −

Save the above Java code as CreateParagraph.java, and then compile and run it from the command prompt as follows −

$javac CreateParagraph.java
$java CreateParagraph

它将编译并执行，在当前目录中生成名为 createparagraph.docx 的 Word 文件，您将在命令提示符中获得以下输出 −

It will compile and execute to generate a Word file named createparagraph.docx in your current directory and you will get the following output in the command prompt −

createparagraph.docx written successfully

createparagraph.docx 文件如下所示。

The createparagraph.docx file looks as follows.

createparagraph
