（使用工具： Free Spire.Presentation for Java）

**JAR包导入**

**方法一：**下载Free Spire.Presentation for Java包并解压缩，然后将lib文件夹下的jar包作为依赖项直接导入到Java应用程序中。

**方法二：**通过Maven仓库安装jar包，配置pom.xml文件的代码如下：

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <url>http://repo.e-iceblue.cn/repository/maven-public/</url>
        </repository>
    </repositories>
    <dependencies>
        <dependency>
            <groupId>e-iceblue</groupId>
            <artifactId>spire.presentation.free</artifactId>
            <version>3.9.0</version>
        </dependency>
    </dependencies>

**Java代码示例**

import com.spire.presentation.Presentation;
    import com.spire.presentation.diagrams.ISmartArt;
    import java.io.*;
    
    //java项目www.fhadmin.org
    public class extractTextFromSmartArt {
        public static void main(String[] args) throws Exception {
            Presentation presentation = new Presentation();
            presentation.loadFromFile("SmartArt.pptx");
    
            //新建txt文档
            String result = "output/extractTextFromSmartArt.txt";
            File file=new File(result);
            if(file.exists()){
                file.delete();
            }
            file.createNewFile();
            FileWriter fw =new FileWriter(file,true);
            BufferedWriter bw =new BufferedWriter(fw);
    
            bw.write("以下内容为从SmartArt中提取到的文本:" + "\r\n");
    
            //遍历所有幻灯片并获取SmartArt图形.
            for (int i = 0; i < presentation.getSlides().getCount(); i++)
            {
                for (int j = 0; j < presentation.getSlides().get(i).getShapes().getCount(); j++)
                {
                    if (presentation.getSlides().get(i).getShapes().get(j) instanceof ISmartArt)
                    {
                        ISmartArt smartArt = (ISmartArt)presentation.getSlides().get(i).getShapes().get(j);
    
                        //提取SmartArt中的文本
                        for (int k = 0; k < smartArt.getNodes().getCount(); k++)
                        {
                            bw.write(smartArt.getNodes().get(k).getTextFrame().getText() + "\r\n");
                        }
                    }
                }
            }
            bw.flush();
            bw.close();
            fw.close();
    
        }
    }
