接到一个任务，要读取doc文件的内容。解析里面的内容，进行一个处理和返回。

### 读取doc: ###

看了

很多文章，基本都是：

import org.apache.poi.hwpf.HWPFDocument;
    import org.apache.poi.hwpf.extractor.WordExtractor;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.IOException;
    
    public class WordImportUtils {
    
        public static String readWordFile(String path) {
            File file = new File(path);
            FileInputStream fileInputStream = null;
            try {
                fileInputStream = new FileInputStream((file.getAbsolutePath()));
                HWPFDocument document = new HWPFDocument(fileInputStream);
                WordExtractor extractor = new WordExtractor(document);
                return extractor.getText();//此处还有很多别的方法可以使用
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                if(fileInputStream != null){
                    try {
                        fileInputStream.close();
                    }catch (Exception e){
                        e.printStackTrace();
                    }
                }
            }
            return "";
        }
    
        public static void main(String args[]) throws Exception {
            String path="D:\\tmp\\invest.doc";
            String content = readWordFile(path);
            System.out.println(content);
        }
    
    }

*  extractor对象的几个get方法说明：
    
     *  getText() ：返回String，全文内容
     *  getMainTextboxText() 返回String\[\]，读取的是多个文本框中的内容
     *  getParagraphText() 返回String\[\]，读取的是多个自然段的内容
 *  读取的图片都没了，表格只保留了文字部分，格式都没有了。其余的格式（换行、回车等）均被保留

里面  
import org.apache.poi.hwpf.HWPFDocument;  
import org.apache.poi.hwpf.extractor.WordExtractor;

这两行报错。

看了下引用：

implementation 'org.apache.poi:poi:3.16'
        implementation 'org.apache.poi:poi-ooxml:3.16'

细看了下代码，确实没有。就直接搜 WordExtractor

原来是少了：poi-scratchpad 的引用 [引用版本查询][Link 1]

implementation 'org.apache.poi:poi-scratchpad:3.16'

这样就正常。

如果是docx或者pdf格式怎么处理呢？

### 读取docx ###

import org.apache.pdfbox.io.RandomAccessBuffer;
    import org.apache.pdfbox.pdfparser.PDFParser;
    import org.apache.pdfbox.pdmodel.PDDocument;
    import org.apache.pdfbox.text.PDFTextStripper;

    import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
    import org.apache.commons.lang.StringUtils;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.InputStream;
    
    public class WordImportUtils {
    
        public static void main(String args[]) throws Exception {
            String path="D:\\tmp\\invest2.docx";
            String docx = readWord(path);
            System.out.println(docx);
        }
        
        public static String readWord(String path) throws Exception {
            File file = new File(path);
            String suffix =  StringUtils.substringAfterLast(path, ".");
            FileInputStream fileInputStream = new FileInputStream((file.getAbsolutePath()));
            return readWord(fileInputStream, suffix);
        }
    
        public static String readWord(InputStream inputStream, String suffix) throws Exception{
            if ("doc".equals(suffix)) {
                HWPFDocument document = new HWPFDocument(inputStream);
                WordExtractor extractor = new WordExtractor(document);
                return extractor.getText();
            } else if ("docx".equals(suffix)) {
                OPCPackage opcPackage = OPCPackage.open(inputStream);
                POIXMLTextExtractor extractor = new XWPFWordExtractor(opcPackage);
                return extractor.getText();
            } else if("pdf".equals(suffix)){
                RandomAccessBuffer rab = new RandomAccessBuffer(inputStream);
                PDFParser pdfParser = new PDFParser(rab);
                pdfParser.parse();
                PDDocument document = pdfParser.getPDDocument();
                // 获取页码
                int pages = document.getNumberOfPages();
                PDFTextStripper stripper = new PDFTextStripper();
                // 设置按顺序输出
                stripper.setSortByPosition(true);
                stripper.setStartPage(1);
                stripper.setEndPage(pages);
                return stripper.getText(document);
            }else{
                return null;
            }
        }
    
       
    
    }

pdf的引用包：

implementation 'org.apache.pdfbox:fontbox:2.0.22'
        implementation 'org.apache.pdfbox:pdfbox:2.0.22'

### 文件上传后读取 ###

#### controller ####

@ApiOperation("读取word")
    @RequestMapping(value = "/extractWordFile", method = RequestMethod.POST)
    public ResultVO extractWordFile(@RequestPart("file") MultipartFile file) throws Exception {
        Map<String, Object> data = importDocService.extractWordFile(file);
        return ResultVO.createSuccess(data);
    }

#### service ####

@Service
    public class ImportDocService {
        private static final Logger logger = LoggerFactory.getLogger(VisitImportDocService.class);
    
        public Map<String, Object> extractWordFile(MultipartFile file) throws Exception{
            String fileSuffix = StringUtils.substringAfterLast(file.getOriginalFilename(), ".");
            String data = WordImportUtils.readWord(file.getInputStream(), fileSuffix);
            // 根据实际的要求去获取到副标题和内容
            String subFirstFix = "";
            String content = "";
            Map<String, Object> result = new HashMap<>();
            result.put("subHead", subFirstFix);
            result.put("content", content);
            return result;
        }
    
    }

### 总结： ###

读取doc文件主要是 poi-scratchpad的正确引入。这边主要是处理文本的。后续有需要处理其它的，再进行添加处理
