SpringBoot实现调用自定义的应用程序((最新推荐)

目录

• 1.应用程序设置全局可执行
• 2.在代码中配置调用程序的指令，并在Service中引入
• 3.编写命令执行方法
• 4.如命令执行时间过长，可先返回命令调用情况，后续进行任务的更新操作

1.应用程序设置全局可执行

添加安装路径到全局变量中，并执行source指令使其生效

export PATH=$PATH:/the/path/to/software

source /etc/profile

2.在代码中配置调用程序的指令，并在Service中引入

coverage:
command: coverage

@Value("${coverage.command}")
private String coverageCommand;

3.编写命令执行方法

    /*
     *调用命令并将执行日志写入文件中
     */
public void exeCmd(String commandStr, String logFile) {
        BufferedReader br = null;
        String line = null;
        StringBuilder stringBuild = new StringBuilder();
        try {
            Process p = Runtime.getRuntime().exec(commandStr);
            br = new BufferedReader(new InputStreamReader(p.getInputStream()));
            while ((line = br.readLine()) != null) {
                stringBuild.append(line + "\n");
                log.info(line);
                try (OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(new String(logFile.getBytes("utf-8"))), "utf-8")) {
                    out.append(stringBuild);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
     /*
     *调用命令并返回全部命令执行日志
     */
    public String getVariable(String command) throws IOException {
        BufferedReader br = null;
        String line = null;
        List<String> strings = new ArrayList<>();
        StringBuilder stringBuild = new StringBuilder();
        try {
            Process p = Runtime.getRuntime().exec(command);
            br = new BufferedReader(new InputStreamReader(p.getInputStream()));
            while ((line = br.readLine()) != null) {
                stringBuild.append(line + "\n");
                strings.add(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
        return strings.toString();
    }

4.如命令执行时间过长，可先返回命令调用情况，后续进行任务的更新操作

ExecutorService executorService = Executors.newFixedThreadPool(2);
CompletableFuture<Integer> future = CompletableFuture.supplyAsync(new Supplier<Integer>() {
                @Override
                public Integer get() {
                    log.info("开始执行算法-------");
                    exeCmd(commendStr, outLog());
                    log.info("算法执行结束");
                    File txtFile = new File(outLog);
                    //根据实际加工逻辑进行更新或其他操作
                    if (txtFile.exists()) {
                        task.setSuccessTime(new Date());
                        task.setTaskStatus("SUCCESS");
                    } else {
                        task.setErrorTime(new Date());
                        task.setTaskStatus("ERROR");
                    }
                    taskMapper.updateTaskInfo(task);
                    return 3;
                }
            }, executorService);
future.thenAccept(e -> System.out.println(e));
