使用HttpHandler进行对象序列化时出现java.io.EOFException错误

我正在尝试序列化

HttpHandler

类中的对象

我有两个文件，

Server3.java

：

package server3;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.OutputStream;
import java.io.Serializable;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;

public class Server3 {
public static void main(String[] args) throws Exception {

HttpServer server = HttpServer.create(new InetSocketAddress(3333), 0);
server.createContext("/", new MyHandler());
server.setExecutor(null); // creates a default executor
server.start();
}

static class MyHandler implements HttpHandler {
public void handle(HttpExchange t) throws IOException {
        String response = "Kjo eshte nje pergjigje nga serveri! n";

        t.sendResponseHeaders(200, response.length());
        OutputStream os = t.getResponseBody();
        os.write(response.getBytes());
        os.close();

        Personat obj = new Personat();
        ObjectOutputStream objOut = new     ObjectOutputStream(t.getResponseBody());
        objOut.writeObject(obj);
        objOut.close();
}
}
}
class Personat implements Serializable{
private static final long serialVersionUID = 1L;
int ID=3;
String Name="Andi";
}

package server3;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.ObjectInputStream;
import java.net.HttpURLConnection;
import java.net.URL;
//te gjithe personat qe jan ne database me nej objekt 
public class Client3 {
public static void main(String[] args) throws Exception {
    try {
        URL url = new URL("http://localhost:3333");
        HttpURLConnection s = (HttpURLConnection) url.openConnection();
        s.setDoOutput(true);
        s.setDoInput(true);
        s.setRequestMethod("POST");
        s.setUseCaches(false);

        InputStream in = s.getInputStream();
        InputStreamReader isr = new InputStreamReader(in);
        BufferedReader br = new BufferedReader(isr);
        int c;
        while ((c = br.read()) != -1) {
            System.out.print((char) c);
        }
        ObjectInputStream ios = new ObjectInputStream(s.getInputStream());
        Personat oin = (Personat) ios.readObject();
        String emri=oin.Name;
        System.out.println(emri);
        ios.close();
        s.disconnect();
    } catch (IOException ex) {
        System.err.println(ex);
        System.out.print(ex);
    }
}
  }

和

Client3.java

：

package server3;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.OutputStream;
import java.io.Serializable;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpExchange;

public class Server3 {
public static void main(String[] args) throws Exception {

HttpServer server = HttpServer.create(new InetSocketAddress(3333), 0);
server.createContext("/", new MyHandler());
server.setExecutor(null); // creates a default executor
server.start();
}

static class MyHandler implements HttpHandler {
public void handle(HttpExchange t) throws IOException {
        String response = "Kjo eshte nje pergjigje nga serveri! n";

        t.sendResponseHeaders(200, response.length());
        OutputStream os = t.getResponseBody();
        os.write(response.getBytes());
        os.close();

        Personat obj = new Personat();
        ObjectOutputStream objOut = new     ObjectOutputStream(t.getResponseBody());
        objOut.writeObject(obj);
        objOut.close();
}
}
}
class Personat implements Serializable{
private static final long serialVersionUID = 1L;
int ID=3;
String Name="Andi";
}

package server3;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.ObjectInputStream;
import java.net.HttpURLConnection;
import java.net.URL;
//te gjithe personat qe jan ne database me nej objekt 
public class Client3 {

    try {
        URL url = new URL("http://localhost:3333");
        HttpURLConnection s = (HttpURLConnection) url.openConnection();
        s.setDoOutput(true);
        s.setDoInput(true);
        s.setRequestMethod("POST");
        s.setUseCaches(false);

        InputStream in = s.getInputStream();
        InputStreamReader isr = new InputStreamReader(in);
        BufferedReader br = new BufferedReader(isr);
        int c;
        while ((c = br.read()) != -1) {
            System.out.print((char) c);
        }
        ObjectInputStream ios = new ObjectInputStream(s.getInputStream());
        Personat oin = (Personat) ios.readObject();
        String emri=oin.Name;
        System.out.println(emri);
        ios.close();
        s.disconnect();
    } catch (IOException ex) {
        System.err.println(ex);
        System.out.print(ex);
    }
}
  }

但当我运行它时，eclipse会显示给我

java.io.EOFException Kjo eshte nje pergjigje nga serveri! njava.io.EOFException`

我不明白为什么。

来自java文档

表示在输入过程中意外到达文件结尾或流结尾

此异常主要由数据输入流用于向流结束发送信号。请注意，许多其他输入操作在流的末尾返回一个特殊值，而不是抛出异常

eofeexception

是

IOException

的子类。如果您试图从流中读取数据，并且没有更多的数据要读取，则会抛出该消息

我认为在

InputStream

中，在阅读以下内容后，什么都没有了：

InputStream in = s.getInputStream();
InputStreamReader isr = new InputStreamReader(in);
BufferedReader br = new BufferedReader(isr);
int c;
while ((c = br.read()) != -1) {
    System.out.print((char) c);
 }

---

问题是您试图将字符串

response

和对象都放入

response.length（）

字节中。发生的情况是只发送

response.length（）

字节，因此，如果您尝试读取更多内容，就会得到

EOFEException

如果改为将

responseLength

参数设置为0，则允许传输任意数量的数据

t.sendResponseHeaders(200, 0); 

---

如果要向流中写入更多数据，也不应关闭流。在所有写入操作完成之前，不要调用

os.close（）

我已经删除了整个部分

InputStream in=s.getInputStream（）；InputStreamReader isr=新的InputStreamReader（in）；BufferedReader br=新的BufferedReader（isr）；INTC；while（（c=br.read（））！=-1）{System.out.print（（char）c）；}

还有server.java端的参考，现在它显示了此错误

java.net.SocketException:来自服务器的文件意外结束java.net.SocketException:来自服务器的文件意外结束

非常感谢！！！！我有两天（16小时）的时间来完成这项工作，但我就是做不到！！！现在我终于可以完成我的工作了！！！所以再次谢谢你！！！
