将数据从Python程序发送到Java程序 [英] Send data from Python program to Java program

问题描述

我有一个Python程序 status.py ，该程序将一些状态更新（字符串）打印到控制台。但是，我需要编写一个JavaFX程序 Display.java ，该程序将启动Python程序，然后将Python程序的状态更新打印到 TextArea 。

I have a Python program status.py that prints some status updates (strings) to the console. However, I need to write a JavaFX program Display.java that launches the Python program and then prints the Python program's status updates to a TextArea.

要完成此操作，我更改了 status.py ，将其状态更新写入文本文件，然后让Java程序将文本文件读取到 TextArea 中。

To accomplish this I've altered status.py to write its status updates to a text file and then have the Java program read the text file into the TextArea.

文本文件方法有效，但我觉得有更好的通信方式。我正在考虑让Python程序将其状态更新写入套接字，并让Java程序使用 ServerSocket 监听套接字。

The text file method is working, but I feel like there is a better way to communicate. I am thinking about having the Python program write its status updates to a socket and having the Java program listen to the socket using ServerSocket.

正在使用一种网络方法，例如通过套接字进行通信，这是完成 status.py 与 Display.java ？如果不是，那么完成这种进程间通信的最佳方法是什么？

Is using a networking approach such as communicating through sockets the best way to accomplish communication between status.py and Display.java? If not, what is the best way to accomplish such inter-proccess communication?

推荐答案

有两种方法可以从Python进程转换为Java进程：

There are two options for communicating information from a Python process to a Java process:

1. Java流行的网络库将使通过套接字轻松读取数据变得容易。由于您可以轻松地在Python中打开套接字，因此实现套接字通信将是最简单的解决方案。


2. 如果您具有 Jython ，您可以通过将Python代码包含在Java代码中来消除执行进程间通信的需要。

1. Java's popular networking libraries will make it easy to read in data through a socket. Since you can easily open up a socket in Python, implementing socket communication would be the easiest solution.
2. If you have experience with Jython, you can eliminate the need to perform inter-process communication by including the Python code within the Java code.
