mongo数据库对图片的存储

先建立一个数据库连接public MongoDB(String dbName) throws UnknownHostException, MongoException {    connection = new Mongo('192.168.19.208:27017');    db = connection.getDB(dbName);}

向数据库中存入图片public void inputPage()   try {       String newFileName =“phone”；       File imageFile =new File('c:\\JavaWebHosting.png')       GridFS gfsPhoto =new GridFS(db);       GridFSInputFile gfsFile = gfsPhoto.createFile(imageFile)       gfsFile.setFilename(newFileName)       gfsFile.save();   } catch (IOException e) {       e.printStackTrace();   }}
