Java对word文件的读写

一、使用 POI 

       在网上找了一些读写代码，读文件没得问题，但是，写入的文件，无法用word打开。用纯文本工具打开能看到写入的文字，说明是以字符的形式写入了，而不是以word 的二进制格式写入。弄了半天也没找到原因，于是放弃，转而采用jacob

   读取word代码：

public static String getWordContent(File wordFile) throws Exception {FileInputStream in = new FileInputStream(wordFile);WordExtractor extractor = new WordExtractor(in);String text = extractor.getText();return text;}

文件写入代码：

ByteArrayInputStream bais = new ByteArrayInputStream(content.getBytes());POIFSFileSystem fs = new POIFSFileSystem();DirectoryEntry directory = fs.getRoot();DocumentEntry de = directory.createDocument("WordDocument", bais);FileOutputStream ostream = new FileOutputStream(new File(fileName));fs.writeFilesystem(ostream);bais.close();ostream.flush();ostream.close();

二、使用jacob

jacob 需要dll的支持，其原理是 建立起java和COM组件之间的桥梁，调用COM来完成操作，个人不是很喜欢这样的调用方式。
