在Java中调用Python脚本可以使用以下几种方法:
使用Runtime类的exec方法执行Python脚本:String command = "python path/to/python/script.py";Process process = Runtime.getRuntime().exec(command);BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));String line;while ((line = input.readLine()) != null) { System.out.println(line);}input.close();使用ProcessBuilder类执行Python脚本:ProcessBuilder pb = new ProcessBuilder("python", "path/to/python/script.py");Process process = pb.start();BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));String line;while ((line = input.readLine()) != null) { System.out.println(line);}input.close();使用Jython库将Python代码嵌入到Java中执行:首先需要在项目中引入Jython库,然后可以直接在Java代码中调用Python代码:
import org.python.core.PyObject;import org.python.util.PythonInterpreter;public class Main { public static void main(String[] args) { PythonInterpreter interpreter = new PythonInterpreter(); interpreter.execfile("path/to/python/script.py"); PyObject someFunc = interpreter.get("someFunc"); someFunc.__call__(); }}这些是在Java中调用Python脚本的几种常用方法,可以根据具体需求选择适合的方法。
