springboot通过接口执行本地shell脚本

首先创建springboot项目
shell脚本

#!/bin/sh
 echo 'Hello World！'

然后编写执行shell脚本的util类

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class ShellUtils {

    /**
     * @param pathOrCommand 脚本路径或者命令
     * @return
     */
    public static List<String> exceShell(String pathOrCommand) {
        List<String> result = new ArrayList<>();

        try {
            // 执行脚本
            Process ps = Runtime.getRuntime().exec(pathOrCommand);
            int exitValue = ps.waitFor();
            if (0 != exitValue) {
                System.out.println("call shell failed. error code is :" + exitValue);
            }

            // 只能接收脚本echo打印的数据，并且是echo打印的最后一次数据
            BufferedInputStream in = new BufferedInputStream(ps.getInputStream());
            BufferedReader br = new BufferedReader(new InputStreamReader(in));
            String line;
            while ((line = br.readLine()) != null) {
                System.out.println("脚本返回的数据如下： " + line);
                result.add(line);
            }
            in.close();
            br.close();

        } catch (Exception e) {
            e.printStackTrace();
        }

        return result;
    }
}

最后开发接口调用此类

@RestController
@RequestMapping("/shell/test")
public class ShellTestController {

    @GetMapping("/shell")
    public List<String> shellTest(){
        List<String> list = ShellUtils.exceShell("/home/shelltest/test.sh");
        return list;
    }
}
