我正在通过 Sockets 创建一个更新客户端,并且在服务器端得到了一个 Broken Pipe。服务器接受客户端套接字并使用消息或大字节数组(~180MB)响应同一个套接字。在本地测试(客户端和服务器在同一台机器上)时不会发生该错误,并且似乎在发送字节数组时发生。我没有在客户端套接字上指定超时,并且在阅读完整响应之前不知道它为什么要关闭。这是我第一次使用套接字,任何帮助将不胜感激。
我的客户端套接字代码:
public static Response makeRequest(Request req) throws IOException {
Response response = null;
Socket echoSocket = null;
ObjectOutputStream out = null;
ObjectInputStream in = null;
echoSocket = new Socket(serverHost, 10008);
out = new ObjectOutputStream(echoSocket.getOutputStream());
in = new ObjectInputStream(
echoSocket.getInputStream());
BufferedReader stdIn = new BufferedReader(
new InputStreamReader(System.in));
out.writeObject(req);
try {
response = (Response)in.readObject();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
out.close();
in.close();
stdIn.close();
echoSocket.close();
return response;
}
Response 只是一个 POJO 保存响应(string/byte[] 和其他数据)
我的服务器代码(复制了 Sun/Oracle 站点的示例并将我的代码添加到其中)
public class Server extends Thread {
private Socket clientSocket;
public Server(Socket clientSocket) {
this.clientSocket = clientSocket;
start();
}
public void run()
{
{
System.out.println ("New Communication Thread Started");
try {
ObjectOutputStream out = new ObjectOutputStream(clientSocket.getOutputStream());
ObjectInputStream in = new ObjectInputStream(clientSocket.getInputStream());
Request request = null;
try {
request = (Request)in.readObject();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
UpdateDAO dao = new UpdateDAO();
ClientDAO cdao = new ClientDAO();
Update update = null;
Client client = null;
Session s = HibernateUtil.currentSession();
Transaction t = s.beginTransaction();
if (request != null) {
client = cdao.getClient(request.getClientId());
LogItem log = new LogItem();
log.setClient(client);
log.setTimestamp(new Date());
log.setAction(request.getAction());
if (request.getResponse() != null) {
update = dao.getUpdate(request.getResponse().getUpdateId());
}
TaskContext ctx = new TaskContext(request, client, update, log);
System.out.println("Action: " + request.getAction().getDescription());
Task task = TaskFactory.getTask(request.getAction());
System.out.println(task.getClass().getName());
Response response = task.perform(ctx);
out.writeObject(response);
log.setClientTaskDescription(request.getMessage());
log.setUpdate(ctx.getUpdate());
dao.save(ctx.getLog());
if (ctx.getUpdate() != null) {
dao.update(ctx.getUpdate());
}
} else {
out.writeObject(new Response("what"));
}
t.commit();
out.close();
in.close();
clientSocket.close();
}
