java调用python传参数_python窗口图形界面编程在 Java 中调用 Python 脚本并传递参数可以通过以下几种方式实现 使用 Runtime exec 方法 javatry String arguments new String python path to your python script py arg1 arg2 argN Process process

在Java中调用Python脚本并传递参数可以通过以下几种方式实现:

使用`Runtime.exec`方法

 try { String[] arguments = new String[] { "python", "path_to_your_python_script.py", "arg1", "arg2", // ... "argN" }; Process process = Runtime.getRuntime().exec(arguments); BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream())); String line; while ((line = in.readLine()) != null) { System.out.println(line); } process.waitFor(); } catch (IOException | InterruptedException e) { e.printStackTrace(); } 

使用`ProcessBuilder`类

 try { ProcessBuilder processBuilder = new ProcessBuilder("python", "path_to_your_python_script.py", "arg1", "arg2", /* ... */); Process process = processBuilder.start(); BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream())); String line; while ((line = in.readLine()) != null) { System.out.println(line); } process.waitFor(); } catch (IOException | InterruptedException e) { e.printStackTrace(); } 

使用`jython`库(不推荐,因为可能不支持所有第三方库):

 import org.python.util.PythonInterpreter; public class JavaCallPython { public static void main(String[] args) { try (PythonInterpreter interpreter = new PythonInterpreter()) { interpreter.execfile("path_to_your_python_script.py"); interpreter.set("arg1", "value1"); interpreter.set("arg2", "value2"); // ... interpreter.execfile("path_to_your_python_script.py"); } } } 

使用`ProcessBuilder`传递参数(适用于Windows和Linux系统):

 try { ProcessBuilder processBuilder = new ProcessBuilder("python", "path_to_your_python_script.py", "arg1", "arg2", /* ... */); Process process = processBuilder.start(); BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream())); String line; while ((line = in.readLine()) != null) { System.out.println(line); } process.waitFor(); } catch (IOException | InterruptedException e) { e.printStackTrace(); } 

请确保Python脚本路径正确,参数传递无误。如果有特殊字符或空格,请使用双引号将参数值括起来。
