更新数据库操作，执行了292分钟之后出现了这个问题退出，这是什么原因？
代码：
public static String getDataFromUrl(String url) throws IOException { String getURL = url; URL getUrl = new URL(getURL); HttpURLConnection connection = (HttpURLConnection) getUrl.openConnection(); connection.connect(); BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));//出错行at GetUserData.getDataFromUrl(GetUserData.java:112) String lines; String result = ""; while ((lines = reader.readLine()) != null) { result = result + lines; } reader.close(); connection.disconnect(); return result; }
