问题描述
我有一个在服务器端使用套接字的客户端-服务器程序,并且读写是以这种方式发生的
I have a client-server program using socket on the server side and read and write is happening in that way
soc = serversocket.accept(); System.out.println("Accepted"); in = new ObjectInputStream(soc.getInputStream()); out = new ObjectOutputStream(soc.getOutputStream()); if(in.readUTF() == null ? " " != null : !in.readUTF().equals(" ")) { diskinfo.setPath(in.readUTF()); } Item[] pac = diskinfo.get(); out.writeObject(pac);
同样在 cilent(android) 方面...
and similarly on the cilent(android) side...
Log.v("read", "item"); soc = new Socket(InetAddress.getByName("10.0.2.2"), 3838); output = new ObjectOutputStream(soc.getOutputStream()); input = new ObjectInputStream(soc.getInputStream()); try { output.writeUTF(path); packets = (Item[]) input.readObject(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); }
问题是,连接建立后程序卡住了,不报错也不例外;停下来
The problem is that, after the connection is established the program stuck their, giving no error no exception; just stop
推荐答案
这是一个死锁,你必须先创建并刷新 ObjectOutputStream.这是因为 ObjectInputStream 在继续之前会读取 OOS 发送的 header.
Its a deadlock, you must create and flush the ObjectOutputStream first. This is because ObjectInputStream reads the header sent by the OOS before continuing.
