本文介绍了一个项目需求，即通过REST API来执行Python和Shell脚本。示例中展示了如何在Java控制器中调用Runtime类来运行Python脚本`hello.py`和Shell脚本`hello.sh`，并提供了测试接口`/api/v1/op/shell`的调用方法。

前言

最近项目上有一个需求需要暴露rest请求，这个rest请求要去执行python或者shell脚本；

1、目录结构

在这里插入图片描述

2、py示例

print 'hello python'

3、shell示例

echo 'hello shell'
mkdir hello

4、rest接口示例

package com.hxs.demo.soon.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Collections;
import java.util.List;

/**

@RestController
@RequestMapping(path = "/api/v1/op")
public class OptionController {
    private static final String PYNAME ="hello.py";
    private static final String SHELLNAME ="hello.sh";

    @GetMapping(path = "/python")
    public List<String> python() {
        String path = OptionController.class.getClassLoader().getResource("").getPath();
        Process proc;
        try {
            //执行脚本
            proc = Runtime.getRuntime().exec("python " + path + PYNAME);
            BufferedReader in = new BufferedReader(new InputStreamReader(proc.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
            in.close();
            proc.waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }

        return Collections.singletonList("success");
    }

    @GetMapping(path = "/shell")
    public List<String> shell() {
        String path = OptionController.class.getClassLoader().getResource("").getPath();
        try {
            //先授权
            ProcessBuilder pb = new ProcessBuilder("/bin/chmod", "755", path+SHELLNAME);
            Process ps = pb.start();
            ps.waitFor();

            //执行脚本
            Process process = Runtime.getRuntime().exec(path+SHELLNAME);
            BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
            in.close();
            process.waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }

        return Collections.singletonList("success");
    }
}
