python用socket传输json格式数据给java

import socket
import json

#一个对象
class msg:
    def __init__(self, name='hfz', age=18):
        self.age = age
        self.name = name

#连接服务器
sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sk.connect(('127.0.0.1', 9001))
#创建对象
data = msg()
print(data)
#转换字典
dataDict = data.__dict__
print(dataDict)
#转换json
dataJson = json.dumps(dataDict)
print(type(dataJson))
#序列化字节编码
sk.send(dataJson.encode())

import java.io.InputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class sockServer {
    public static void main(String[] args) throws Exception{
        ServerSocket server = new ServerSocket(9001);
        Socket socket = server.accept();
        InputStream inputStream = socket.getInputStream();


        byte[] bytes = new byte[1024];
        int len = inputStream.read(bytes);
        String data = new String(bytes,0,len);
        System.out.println(data);
        
        server.close();
    }
}
