以下是使用Java的ProcessBuilder调用Python程序或脚本的示例： ### 示例一：简单调用Python脚本 ```java import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStreamReader; public class ProcessBuilderPythonExample { public static void main(String[] args) { try { // 创建ProcessBuilder对象，指定Python解释器和Python脚本路径 ProcessBuilder pb = new ProcessBuilder("python", "path/to/your/script.py"); // 启动进程 Process process = pb.start(); // 获取进程的输入流 BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); String line; // 读取Python脚本的输出 while ((line = reader.readLine()) != null) { System.out.println(line); } // 等待进程执行完毕 int exitCode = process.waitFor(); System.out.println("Process exited with code " + exitCode); } catch (IOException | InterruptedException e) { e.printStackTrace(); } } } ``` ### 示例二：带参数调用Python脚本 ```java import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class ProcessBuilderPythonWithArgsExample { public static void main(String[] args) { try { // 创建ProcessBuilder对象，指定Python解释器、Python脚本路径和参数 ProcessBuilder pb = new ProcessBuilder("python", "path/to/your/script.py", "arg1", "arg2"); // 启动进程 Process process = pb.start(); // 获取进程的输入流 BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); String line; // 读取Python脚本的输出 while ((line = reader.readLine()) != null) { System.out.println(line); } // 等待进程执行完毕 int exitCode = process.waitFor(); System.out.println("Process exited with code " + exitCode); } catch (IOException | InterruptedException e) { e.printStackTrace(); } } } ``` ### 示例三：从引用中的实际案例 ```java import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStreamReader; public class CosyVoice3Example { public static void main(String[] args) { try { ProcessBuilder pb = new ProcessBuilder("python", "/root/run.py"); pb.directory(new File("/root")); pb.redirectErrorStream(true); // 合并错误流，便于统一处理 Process process = pb.start(); BufferedReader reader = new BufferedReader( new InputStreamReader(process.getInputStream()) ); String line; while ((line = reader.readLine()) != null) { System.out.println("[Python] " + line); if (line.contains("Running on http://0.0.0.0:7860")) { System.out.println("✅ CosyVoice3 服务已就绪！"); break; // 可通知前端或释放等待线程 } } } catch (IOException e) { e.printStackTrace(); } } } ``` ### 示例四：另一个带参数的案例 ```java import java.io.IOException; public class AnotherExample { public static void main(String[] args) { try { ProcessBuilder pb = new ProcessBuilder("C:\\Python34\\python.exe", "D:\\New folder\\test\\src\\NewCodes\\pickel4output.py", "may", "vay"); Process process = pb.start(); } catch (IOException e) { e.printStackTrace(); } } } ```
