网络连接的疑惑

Question

public class Client {    
    public static void main(String[] arg) {    
        try {    
            Employee joe = new Employee(150, "Joe");    
            System.out.println("employeeNumber= " + joe.getEmployeeNumber());    
            System.out.println("employeeName= " + joe.getEmployeeName());    
            Socket socketConnection = new Socket("127.0.0.1", 11111);    
            ObjectOutputStream clientOutputStream = new ObjectOutputStream(    
                    socketConnection.getOutputStream());    
            ObjectInputStream clientInputStream = new ObjectInputStream(    
                    socketConnection.getInputStream());    
            clientOutputStream.writeObject(joe);    
            joe = (Employee) clientInputStream.readObject();    
            System.out.println("employeeNumber= " + joe.getEmployeeNumber());    
            System.out.println("employeeName= " + joe.getEmployeeName());    
            clientOutputStream.close();    
            clientInputStream.close();    
        } catch (Exception e) {    
            System.out.println(e);    
        }    
    }    
}   

Answer 1

public class Server {    
    public static void main(String[] arg) {    
        Employee employee = null;    
        try {    
            ServerSocket socketConnection = new ServerSocket(11111);    
            System.out.println("Server Waiting");    
            Socket pipe = socketConnection.accept();    
            ObjectInputStream serverInputStream = new ObjectInputStream(pipe    
                    .getInputStream());    
            ObjectOutputStream serverOutputStream = new ObjectOutputStream(pipe    
                    .getOutputStream());    
            employee = (Employee) serverInputStream.readObject();    
            employee.setEmployeeNumber(256);    
            employee.setEmployeeName("li");    
            serverOutputStream.writeObject(employee);    
            serverInputStream.close();    
            serverOutputStream.close();    
        } catch (Exception e) {    
            System.out.println(e);    
        }    
    }    
}   

Answer 2

public class Employee implements Serializable {  }传递的对象要实现序列化接口！

Answer 3

我想，还是传递xml文件更好一点，兼容性更高。java 自己也提供了把Object转化为xml的类XMLEncoder 和 XMLDecoder

Answer 4

一定要用socketConnection连接吗？
用SocketServer不行吗？

Answer 5

我要传的类是数组的形式，用for循环做的，解决不了问题呀?类是序列化的
SERVER：
ServerListener(Socket t) throws IOException{
this.socket = t;
in = new ObjectInputStream(socket.getInputStream());
out = new ObjectOutputStream(socket.getOutputStream());
}

public void run() {
dao = new CSDAO();
Opertor[] opertor;
try {
opertor = dao.getAllOpertor();//从数据库获得数据
for(int i=0;i<opertor.length;i++){
out.writeObject(opertor[i]);
}
} catch (Exception e) {}
finally{
try {
in.close();out.close();
} catch (IOException e) {}
}
}
CLIENT:
public ClientConnection(String id) throws CsException, IOException {
address = new NetAddress();
inet = address.getNetAddress(id);
socket = new Socket(inet,1245);
}

public Opertor[] getOpertorName() throws CsException, IOException,ClassNotFoundException {
in = new ObjectInputStream(socket.getInputStream());
out = new ObjectOutputStream(socket.getOutputStream());
Opertor opertor[] = new Opertor[3];//数组为3个，不越界
for(int i=0;i<3;i++){
  opertor[i] = (Opertor) in.readObject();
}
in.close();out.close();
return opertor;
}
