public class ShellTest {
    private String callScript( String... workspace) {
        try {
            File dir = null;
            if (workspace[0] != null) {
                dir = new File(workspace[0]);
                System.out.println(workspace[0]);
            }
           // String[] evnp = {"val=2", "call=Bash Shell"};
            Process process = Runtime.getRuntime().exec("./invokeJ.sh", null, dir);
            BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));
            StringBuilder result = new StringBuilder();
            String line;
            while ((line = input.readLine()) != null) {
                result.append(line);
                result.append("\n");
            }
            input.close();
            return result.toString();
        } catch (Exception e) {
            e.printStackTrace();
            return "invoke error!";
        }
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ShellTest call = new ShellTest();
        System.err.println(call.callScript("/export/data/shell"));
    }
}

shell脚本的路径和内容如下：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0lCTGlwbHVz_size_16_color_FFFFFF_t_70

执行结果：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0lCTGlwbHVz_size_16_color_FFFFFF_t_70 1

下面是我在服务中封装的方法

private void invokeCommand(final HttpExchange httpExchange) {
        logger.info("invoke command service start!");
        String requestBody = IOUtil.readStream(httpExchange.getRequestBody());
        CommandDefinition command = JSON.parseObject(requestBody, CommandDefinition.class);
        Assert.checkNonNull(command);
        Assert.check(StringUtils.isBlank(command.getCommand()), "command is null");
        Assert.check(StringUtils.isBlank(command.getDir()), "dir is null");
        logger.info("invoke command request body:{}", JSONObject.toJSONString(command));
        String result = executeCommand(command);
        logger.info("invoke command result:{}", result);
    }
    private String executeCommand(CommandDefinition command) {
        try {
            File dirTmp = new File(command.getDir());
            Process process = Runtime.getRuntime().exec(command.getDir(), command.getEnvp(), dirTmp);
            BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));
            StringBuilder result = new StringBuilder();
            String line;
            while ((line = input.readLine()) != null) {
                result.append(line);
                result.append("\n");
            }
            input.close();
            return result.toString();
        } catch (Exception e) {
            e.printStackTrace();
            return "invoke error!";
        }
    }
