Question

我有一个Client_Sock应该将对象客户端发送到Server_Sock。我正在使用Netbeans，在两个项目中，Client_Sock和Server_Sock，我添加了Client类。

Server_Sock

    package com.app;

    @SpringBootApplication // contains @EnableAutoConfiguration @ComponentScan @Configuration   
    public class App {

    @Autowired
    private Service service;

    public static void main(String[] args) {

        final SpringApplication app = new SpringApplication(App.class);
        //app.setShowBanner(false);
        app.run();
    }

    @PostConstruct
    public void foo() {
        System.out.println("Instantiated service name = " + service.serviceName);
    }
    }

Client_Sock

class Connection extends Thread {
static C Ob; 
Socket cs;
Connection(Socket cs) throws Exception {
this.cs = cs;  
this.start();
}
public void run() {
try {
  InputStream is = cs.getInputStream();
  ObjectInputStream ois = new ObjectInputStream(is);
  Client cl = (Client)ois.readObject();  
  Ob.Write(cl);

  cs.close(); is.close(); ois.close(); 
}
catch(IOException e) {e.printStackTrace(); }
catch(ClassNotFoundException e) {e.printStackTrace(); }
 }
}

客户端

@Override
public void actionPerformed(ActionEvent e) { 
    if(e.getActionCommand().equals("connect")){
        try{
            //add the data in client
            Client cl = new Client();
            cl._age=Integer.parseInt(age_.getText());
            cl._id=Integer.parseInt(id_.getText());
            cl._name=name_.getText();

            //check if data is good
            if(cl._age>18 && !cl._name.equals("") && cl._id>1000 && cl._id<9999){
                Socket cs = new Socket("localhost",5555);
                OutputStream os = cs.getOutputStream();

                ObjectOutputStream oos = new ObjectOutputStream(os);
                oos.writeObject(cl); 
                os.close(); oos.close(); cs.close();
                this.setVisible(false);
                this.dispose();
            }
        }
        catch(Exception ex){
            ex.printStackTrace();
        }

    }
}

当我运行项目时，我在Client_Sock上没有错误，但是当服务器应该收到客户端对象时，我收到此错误：

import java.io.Serializable;

class Client implements Serializable{
public String _name;
public Integer _age;
public Integer _id;

Client(){

}
Client(String myName, Integer myAge, Integer myId){
    _name = myName;
    _age = myAge;
    _id = myId;
}
}

我已经阅读了一些关于套接字传输和序列化的文章，但我找不到我收到此错误的原因。你能帮我吗？谢谢。

套接字传输上的java.lang.ClassNotFoundException
