## 一、问题描述 ##

有个需求就是读取word中的内容，poi可以实现这种需求，网上找了下示例，代码如下：

/** * 读取doc文件内容 * * @param fs 想要读取的文件对象 * @return 返回文件内容 * @throws IOException */
        public static String readDoc(FileInputStream fs) throws IOException { 
            StringBuilder result = new StringBuilder();
            WordExtractor re = new WordExtractor(fs);
            result.append(re.getText());
            re.close();
            return result.toString();
        }
    
        public static String readDocToStr(File file) throws IOException { 
            return readDoc(new FileInputStream(file));
        }
    
        public static void main(String[] args) { 
            File file = new File("D:\\xxx\\xxx\\1\\file\\2021\\04\\28\\34a58ac4faa4222712a4329ac60f34f9\\34a58ac4faa4222712a4329ac60f34f9.docx");
            try { 
                System.out.println(readDocToStr(file));
            } catch (IOException e) { 
                e.printStackTrace();
            }
        }

依赖如下：

<dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi</artifactId>
          <version>5.0.0</version>
        </dependency>
        <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-ooxml</artifactId>
          <version>5.0.0</version>
        </dependency>
        <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-scratchpad</artifactId>
          <version>5.0.0</version>
        </dependency>
        <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-ooxml-full</artifactId>
          <version>5.0.0</version>
        </dependency>
        <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi</artifactId>
          <version>5.0.0</version>
        </dependency>

上面的代码运行会报如下错误：

Exception in thread "main" java.lang.IllegalArgumentException: The document is really a OOXML file
    	at org.apache.poi.hwpf.HWPFDocumentCore.verifyAndBuildPOIFS(HWPFDocumentCore.java:126)
    	at org.apache.poi.hwpf.extractor.WordExtractor.<init>(WordExtractor.java:52)

OOXML错误。

## 二、解决方法 ##

报上面的错误就是不能正确的解析docx文档导致的，改成如下就行了：

static String read(InputStream is) throws Exception { 
            System.out.println(FileMagic.valueOf(is));
            String text = "";
            if (FileMagic.valueOf(is) == FileMagic.OLE2) { 
                WordExtractor ex = new WordExtractor(is);
                text = ex.getText();
                ex.close();
            } else if (FileMagic.valueOf(is) == FileMagic.OOXML) { 
                XWPFDocument doc = new XWPFDocument(is);
                XWPFWordExtractor extractor = new XWPFWordExtractor(doc);
                text = extractor.getText();
                extractor.close();
            }
            return text;
        }
    
        public static void main(String[] args) throws Exception { 
            InputStream is = new BufferedInputStream(new FileInputStream("D:\\xxx\\xxx\\1\\file\\2021\\04\\28\\34a58ac4faa4222712a4329ac60f34f9\\34a58ac4faa4222712a4329ac60f34f9.docx")); //really a OOXML Word file
            System.out.println(read(is));
            is.close();
        }
