将输入类型文件插入mySQL表

Question

我想将servlet从表单中获取的photoPath URL插入到我的表中，但是它无效。

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    response.setContentType("text/html;charset=UTF-8");
    String name = request.getParameter("name");
    String number = request.getParameter("contactNumber");
    String position = request.getParameter("position");
    String email = request.getParameter("email");
    String photoPath = request.getParameter("myImage");

    MySqlHandler.registerEmployee(name, number, position, email, photoPath);

}

如果我这样做

    try (PrintWriter out = response.getWriter()) {
        out.println(photoPath);
    }

url显示为150x150.png（这是我的img的名称）所以我知道字符串存储在那里。但是当我将它传递给我的registerEmployee函数时，它会阻止所有数据插入到我的表中。如果我将photoPath设置为某​​个静态字符串，则所有内容都会正确插入。可能有什么不对？我想也许是我从

获得的字符串

request.getParameter("myImage");

包含一些无法插入mysql表的奇怪字符？

  public static void registerEmployee(String name, String number, String position, String email, String photoPath) {
  initConnection();

  try {
      String query = " insert into employee_registry (name, number, position, email, photo_path)"
              + " values (?, ?, ?, ?, ?)";
      PreparedStatement preparedStatement = connection.prepareStatement(query);
      preparedStatement.setString(1, name);
      preparedStatement.setString(2, number);
      preparedStatement.setString(3, position);
      preparedStatement.setString(4, email);
      preparedStatement.setString(5, photoPath);
      preparedStatement.execute();
  } catch (Exception e) {
      e.printStackTrace();
      System.err.println("Exception" + e.getMessage());
  }

  closeConnection();
}
