最新的通信java到python

Question

我想從java運行python腳本，當在java中的東西會改變我想發送有關它的信息到python程序。我不知道它的最佳解決方案。我可以運行python腳本並將啓動信息發送給它，但隨後出現問題。我想通過TCP/IP連接發送的數據，但是當我嘗試這樣做，我有python腳本錯誤：

Caused by: Traceback (most recent call last): 
File "pythonScript.py", line 2, in <module> 
import socket 
ImportError: No module named socket

所以它的一些問題SCOKET進口，但是當我運行這個程序normaly不存在錯誤。它的功能代碼，我用它來運行python腳本：

public void runPythonScript(boolean isCameraOn, String ip){ 
    System.out.println(ip); 
    String[] arguments = {ip}; 
    PythonInterpreter.initialize(System.getProperties(),System.getProperties(), arguments); 
    PythonInterpreter python = new PythonInterpreter(); 
    StringWriter out = new StringWriter(); 
    python.setOut(out); 
    python.execfile("pythonScript.py"); 
    String outputStr = out.toString(); 
    System.out.println(outputStr); 
} 

而且它的Python客戶端的代碼：

import sys 
import socket //ERROR 

print("poczatek") 
print(sys.argv[0]) 
print("koniec") 

HOST = "localhost" 
PORT = 8080 

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
sock.setblocking(0) 
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) 
sock.connect((HOST, PORT)) 

sock.sendall("Hello\n") 
data = sock.recv(1024) 
print("1)", data) 

if (data == "olleH\n"): 
    sock.sendall("Bye\n") 
    data = sock.recv(1024) 
    print("2)", data) 

if (data == "eyB}\n"): 
    sock.close() 
    print("Socket closed") 

Java服務器：

public void sendDataToPythonScript(boolean isCameraOn, String ip) throws 
IOException { 
    String fromClient; 
    String toClient; 

    ServerSocket server = new ServerSocket(8080); 
    System.out.println("wait for connection on port 8080"); 

    boolean run = true; 
    while(run) { 
     Socket client = server.accept(); 
     System.out.println("got connection on port 8080"); 
     BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream())); 
     PrintWriter out = new PrintWriter(client.getOutputStream(),true); 

     fromClient = in.readLine(); 
     System.out.println("received: " + fromClient); 

     if(fromClient.equals("Hello")) { 
      toClient = "olleH"; 
      System.out.println("send olleH"); 
      out.println(toClient); 
      fromClient = in.readLine(); 
      System.out.println("received: " + fromClient); 

      if(fromClient.equals("Bye")) { 
       toClient = "eyB"; 
       System.out.println("send eyB"); 
       out.println(toClient); 
       client.close(); 
       run = false; 
       System.out.println("socket closed"); 
      } 
     } 
    } 
    System.exit(0); 
}

嘗試導入嵌入式插座模塊

import _socket 

如果不能解決問題，請嘗試設置python模塊this link的路徑，以解釋如何在java中設置python的路徑。
