我在我的Servlet类中遇到此异常，当我尝试将文件从客户端应用程序上传到我的服务器时，这是我的servlet doPost代码片段
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
String userName = "admin";
String password = "123";
if (DBManager.getInstance().checkIfCanLogin(userName, password)) {
final Part part = (Part) request.getParts().toArray()[1];
new Thread(() -> {
// bla bla bla
}).start();
} else {
response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
}
}catch (Exception e){
e.printStackTrace();
response.setStatus(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
}
}
这里的行final Part part = (Part) request.getParts().toArray()[1];引发了异常，我试图修复这个问题但是没有发现任何问题，我也是JavaEE的新手，我的背景是来自android，也是我想要解决的问题是一切正常，但重新启动后（我认为没有更多用它）这个Servlet停止工作，问题只有这个servlet，我从客户端发送文件（andorid使用改造）
这是错误日志
