如何从位于docker容器中的java/spring-boot项目运行python脚本(并接收输出)？

FROM openjdk:8-jdk-alpine

# 安装Python
RUN apk add --no-cache python3

# 设置Python环境变量
ENV PYTHONUNBUFFERED=1

# 其他容器配置...

# 拷贝Java/Spring Boot项目到容器中
COPY target/myproject.jar /app/myproject.jar

# 拷贝Python脚本到容器中
COPY script.py /app/script.py

# 设置工作目录
WORKDIR /app

# 定义容器启动命令
CMD ["java", "-jar", "myproject.jar"]

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class PythonRunner {
    public static void main(String[] args) {
        try {
            // 构建命令
            ProcessBuilder pb = new ProcessBuilder("python3", "script.py");
            pb.redirectErrorStream(true);

            // 启动进程
            Process process = pb.start();

            // 读取输出
            BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);
            }

            // 等待进程结束
            int exitCode = process.waitFor();
            System.out.println("Exit Code: " + exitCode);
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }
}

print("Hello from Python!")

docker build -t myproject .
docker run myproject
