1.pom.xml 中新增

<dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi</artifactId>
                <version>4.0.0</version>
            </dependency>
            <dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi-ooxml</artifactId>
                <version>4.0.0</version>
            </dependency>
            <dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi-scratchpad</artifactId>

            </dependency>
            <dependency>
                <groupId>org.apache.poi</groupId>
                <artifactId>poi-scratchpad</artifactId>
                <version>3.17</version>
            </dependency>

2.service

import lombok.extern.slf4j.Slf4j;
    import org.apache.poi.hwpf.HWPFDocument;
    import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
    import org.apache.poi.xwpf.usermodel.XWPFDocument;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.core.io.ClassPathResource;
    import org.springframework.stereotype.Service;
    
    import java.io.InputStream;
    
    @Slf4j
    @Service
    public class PdfService {
    
    
        public void sendPdf(WorkFlowRequestDTO requestDTO) throws Exception {
            testReadByDoc("pdf/aa.docx");
        }
    
        public void testReadByDoc(String filePath) throws Exception {
            String text = "";
            InputStream is = new ClassPathResource((filePath)).getInputStream();
            if (filePath.endsWith("docx")) {
                HWPFDocument doc = new HWPFDocument(is);
                //输出书签信息
                //输出文本
                System.out.println(doc.getDocumentText());
                XWPFDocument doc1= new XWPFDocument(is);
                XWPFWordExtractor extractor = new XWPFWordExtractor(doc1);
                text = extractor.getText();
                extractor.close();
                is.close();
            }
        }
    
    }

3.注意

docx 和doc不能互转 会抛异常（内部的结构不一样）
