以下是两个Java使用ProcessBuilder调用Python程序的案例： 案例一： ```java import java.io.IOException; public class ProcessBuilderExample1 { public static void main(String[] args) { ProcessBuilder pb = new ProcessBuilder("C:\\Python34\\python.exe", "D:\\New folder\\test\\src\\NewCodes\\pickel4output.py","may","vay"); try { Process process = pb.start(); } catch (IOException e) { e.printStackTrace(); } } } ``` 此案例直接创建`ProcessBuilder`对象，指定Python解释器路径和要执行的Python脚本路径以及参数，然后启动进程[^1]。 案例二： ```java import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.nio.file.Path; import java.util.ArrayList; import java.util.List; import org.apache.commons.io.IOUtils; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class ProcessBuilderExample2 { private static final Logger LOGGER = LoggerFactory.getLogger(ProcessBuilderExample2.class); public static int callPythonScript(String pkg, Path path) throws IOException, InterruptedException { List<String> commands = new ArrayList<>(); commands.add("python"); commands.add(pkg); commands.add("--ad=test"); ProcessBuilder processBuilder = new ProcessBuilder(); processBuilder.command(commands); processBuilder.directory(path); processBuilder.redirectErrorStream(true); Process process = processBuilder.start(); StringBuilder result = new StringBuilder(); final BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); try { String line; while ((line = reader.readLine()) != null) { result.append(line); LOGGER.info(processBuilder.command().toString() + " --->: " + line); } } catch (IOException e) { LOGGER.warn("failed to read output from process", e); } finally { IOUtils.closeQuietly(reader); } process.waitFor(); int exit = process.exitValue(); if (exit != 0) { throw new IOException("failed to execute:" + processBuilder.command() + " with result:" + result); } else { return exit; } } } ``` 此案例将Python脚本调用封装在`callPythonScript`方法中，通过`List`添加命令和参数，设置工作目录，处理进程输入流并根据进程退出值判断执行结果[^2]。
