创建文件夹

File outputFile = new File(baseDirectory.getAbsolutePath(), MAVEN_WRAPPER_JAR_PATH);
       if(!outputFile.getParentFile().exists()) {
           if(!outputFile.getParentFile().mkdirs()) {
               log.debug(
                       "- ERROR creating output directory '" + outputFile.getParentFile().getAbsolutePath() + "'");
           }
       }

@GetMapping("/demo")
public void demo() {

    try {
        Path file = Paths.get("D://test").resolve("test.log");
        Resource resource = new UrlResource(file.toUri());
        if (!(resource.exists() || resource.isReadable())) {
            System.out.println("Flase");
 File outputFile = new File(baseDirectory.getAbsolutePath(), MAVEN_WRAPPER_JAR_PATH);
        if(!outputFile.getParentFile().exists()) {
            if(!outputFile.getParentFile().mkdirs()) {
                log.debug(
                        "- ERROR creating output directory '" + outputFile.getParentFile().getAbsolutePath() + "'");
            }
        }        }
        InputStream is = resource.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);
        StringBuilder logBuilder = new StringBuilder("");
        String data = null;

            logBuilder.append(data).append("\n");
        }
        br.close();
        isr.close();
        is.close();
        System.out.println(logBuilder.toString().contains("OK"));
    } catch (IOException e) {
        e.printStackTrace();
