我的多线程服务器/客户端项目出现问题。ObjectInputStream/ObjectOutputStream |客户端接收和发送大量对象(Java)
服务器端很好,但问题出在客户端。
我可以发送和接收的对象我想我需要声明一个ObjectInputStream
和ObjectOutputStream
作为我的类属性,然后实例化它们的构造
每次但问题是,代码上阻塞ObjectInputStream
实例。
这里是我的代码:
客户:
public class agency_auth_gui extends javax.swing.JFrame {
Socket s_service;
ObjectOutputStream out;
ObjectInputStream in;
public agency_auth_gui() {
try {
initComponents();
System.out.println("#Connexion en cours avec le Serveur Bancaire.");
s_service = new Socket("127.0.0.1", 6789);
out = new ObjectOutputStream(new BufferedOutputStream(s_service.getOutputStream()));
in= new ObjectInputStream(new BufferedInputStream(s_service.getInputStream()));
//Authentification du Client GAB
out.writeObject((String) "type:agence");
out.flush();
} catch (UnknownHostException ex) {
Logger.getLogger(agency_auth_gui.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(agency_auth_gui.class.getName()).log(Level.SEVERE, null, ex);
}
}
...
Some automaticaly generated swing code
...
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
try {
// Envoi d'une arraylist exec contenant l'authentification
ArrayList exec = new ArrayList();
exec.add("auth_agent");
exec.add(jTextField1.getText());
exec.add(jTextField2.getText());
out.writeObject((ArrayList) exec);
out.flush();
// Reception de la reponse du serveur pour la fonction authentification
Agent agent = (Agent) in.readObject();
if(agent.getId()==0)
{
System.out.println("null");
}else
{
System.out.println(agent.getId());
}
} catch (IOException ex) {
Logger.getLogger(agency_auth_gui.class.getName()).log(Level.SEVERE, null, ex);
} catch (ClassNotFoundException ex) {
Logger.getLogger(agency_auth_gui.class.getName()).log(Level.SEVERE, null, ex);
}
}
public static void main(String args[]) {
try {
for (javax.swing.UIManager.LookAndFeelInfo info : javax.swing.UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
javax.swing.UIManager.setLookAndFeel(info.getClassName());
break;
}
}
} catch (ClassNotFoundException ex) {
java.util.logging.Logger.getLogger(agency_auth_gui.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (InstantiationException ex) {
java.util.logging.Logger.getLogger(agency_auth_gui.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
} catch (IllegalAccessException ex) {
java.util.logging.Logger.getLogger(agency_auth_gui.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);

最后一句话的相关性是什么? – EJP
你说得对,它没有意义。我误解了这个例子,并认为这些溪流是通过管道输送的,他们显然不需要这样做。 – NilsH
了解,但我怎么做我wana做什么? 我应该如何让我的客户读取并发送尽可能多的对象? – Coldfire
