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

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.POIXMLTextExtractor;import org.apache.poi.hwpf.HWPFDocument;import org.apache.poi.hwpf.extractor.WordExtractor;import org.apache.poi.openxml4j.opc.OPCPackage;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 data = importDocService.extractWordFile(file);return ResultVO.createSuccess(data);}

service

@Servicepublic class ImportDocService {private static final Logger logger = LoggerFactory.getLogger(VisitImportDocService.class);public Map 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 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
