Question

我正在尝试使用套接字从服务器向客户端发送自定义对象（Info）。信息类代码为：

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;


public class Info implements Serializable {


    private static final long serialVersionUID = -8967456786256719218L;


    private String ip;
    private int port;
    private List<String> responsibilityLines;


    public Info(String ip, int port, List<String> responsibilityLines) {
        this.ip = ip;
        this.port = port;
        this.responsibilityLines = responsibilityLines;
    }

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public int getSubscriberPort() {
        return port;
    }

    public void setSubscriberPort(int port) {
        this.port = port;
    }

    public List<String> getResponsibilityLines() {
        return responsibilityLines;
    }

    public void setResponsibilityLines(ArrayList<String> responsibilityLines) {
        this.responsibilityLines = responsibilityLines;
    }

    @Override
    public String toString() {
        return "Info{" +
                "ip='" + ip + '\'' +
                ", port=" + port +
                ", responsibilityLines=" + responsibilityLines +
                '}';
    }
 }

套接字连接已建立，并且其他任何Java对象或原始类型也已成功发送。但是，当我尝试发送Info对象的列表时，客户端将阻塞并等待接收（这永远不会发生）。要从服务器发送对象，请使用：

 List<Info> infoList = new ArrayList<>();
 Info inf = new Info("192.168.78.45", 3456, null);
 infoList.add(inf);
 dos.writeObject(infoList);
 dos.flush();

并接收我使用的对象：

List<Info> infoList;
infoList = (List<Info>) dis.readObject();

dos是ObjectOutputStream，dis是ObjectInputStream。

Answer 1

使用ByteArrayOutputStream作为ObjectOutputStream()的输入

ByteArrayOutputStream bos = new ByteArrayOutputStream()
ObjectOutputStream oos = new ObjectOutputStream(bos)
oos.writeObject(infoList)
oos.close

假设您的服务器知道谁可以解析信息类。

Android-Socket不会发送自定义对象
