问下这个错误是什么引起的

Answer 2

可能是你读取的资源没有以EOF(end of file)符号结尾EOFException 继承自IOException 
给出一个在输入过程中意外地到达文件尾或流尾的信号。 这个异常主要用在数据输入流，它一般期望一个指定格式的二进制文件，并且对它来说该流结束是一个非寻常情况。
大部分其它输入流在流结束时返回一个指定值。 

Answer 3

End Of File估计是你读到了文件结尾还在读  结果Java被你雷到了  然后报了这个错...

Answer 4

我都还没读就到文件尾了！！
inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());

Answer 5

整个方法贴出来大家帮我看看！
public void save_record_db1() {
_file = cf.getpath("") + "/log/" + df.format(new Date())
+ ".log";
String result = "";
String hostName = "172.16.31.88";
int port = 8080;
String servletPath = "/depot/GeneralHandleSvt?reqType=utility.UtilActionHandler.save_record";
String webServerStr = "http://" + hostName + ":" + port
+ servletPath;
System.out.println("web str is " + webServerStr);
String servletGET = webServerStr; 
// + "&"
// + URLEncoder.encode("backdoor") + "="
// + URLEncoder.encode("qJdBlE"); ObjectInputStream inputFromServlet = null; try {

System.out.println("Connecting...");
URL DBservlet = new URL(servletGET);
HttpURLConnection servletConnection =(HttpURLConnection) DBservlet.openConnection();
//servletConnection.connect();
System.out.println("Connected"); //servletConnection.setDoInput(true);
servletConnection.setDoOutput(true);
servletConnection.setUseCaches(false);
servletConnection.setRequestProperty("Content-Type",
"application/octet-stream");
ObjectOutputStream outputToServlet = null;
System.out.println("Sending the maintainv to the servlet...");
outputToServlet = new ObjectOutputStream(servletConnection
.getOutputStream());
outputToServlet.writeObject(iw.getAllLine(_file));
outputToServlet.flush();
outputToServlet.close();
System.out.println("Complete.");
System.out.println("Refreshing the list"); System.out.println("Getting input stream");
//System.out.println(servletConnection.getHeaderField(2)+"######");
inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
inputFromServlet.close();
}

catch (Exception e) {
e.printStackTrace();
}
