Java 如何使用blob在mysql数据库中存储文件

我已经搜索了很多关于这个问题的信息，但是，我没有找到一个适合我的问题的解决方案，我有以下使用java存储文件的方法

private void uploadFile() throws Exception {
        Class.forName("com.mysql.jdbc.Driver").newInstance();
        connection = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/FileDb?autoReconnect=true", "user1", "123789");
        System.out.println("DB connection extablished!");

        PreparedStatement statement = connection.prepareStatement("INSERT INTO FilesTb(`FileData`) VAULES(?)");

        File file = new File(txtDir.getText() + "/" + txtFile.getText());// get path and file name from text fields

        FileInputStream fIn = new FileInputStream(file);
        statement.setBlob(1, fIn);
        statement.executeUpdate();
        JOptionPane.showMessageDialog(null, "File stored successfully!");

    }

当我试着运行这段代码时，我得到了以下错误：

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:您的SQL语法有错误；查看与您的MySQL服务器版本相对应的手册，以了解可在“VAULES（\u binary）”附近使用的正确语法
将文件数据转换为字节数组并在sql语句中设置

File fBlob = new File ("<your_path>");
FileInputStream is = new FileInputStream(fBlob);
statement.setBinaryStream(1, is, (int) fBlob.length());
statement.execute();

File fBlob=新文件（“”）；
FileInputStream is=新的FileInputStream（fBlob）；
语句.setBinaryStream（1，is，（int）fBlob.length（））；
语句。execute（）；
试试这个

File fBlob = new File ("<your_path>");
FileInputStream is = new FileInputStream(fBlob);
statement.setBinaryStream(1, is, (int) fBlob.length());
statement.execute();

File fBlob=新文件（“”）；
FileInputStream is=新的FileInputStream（fBlob）；
语句.setBinaryStream（1，is，（int）fBlob.length（））；
语句。execute（）；
