如何从 Java 异步运行 JBoss 服务器应用程序

Question

在我的java应用程序中，我需要运行一个带有文件standalone.bat的Jboss服务器。

我尝试了ProcessBuilder，虽然它确实启动了服务器，但我的应用程序被阻止等待服务器关闭

    @RequestMapping(value = "api/project/liststart", method = RequestMethod.POST)
    public HttpEntity<Boolean> postListServer(@RequestBody ListStart modules) throws Throwable {
        String cmd = "";
        Boolean response = false;
        ProcessBuilder processBuilder = new ProcessBuilder();
        String path = "C:\jboss-as-7.1.1.Final\bin\";
        String command = standelone.bat+ " >sometext.txt"  ;
        processBuilder.command("cmd.exe", "/c", command);
        processBuilder.directory(new File(path));
        Process process = processBuilder.start();
        BufferedReader reader =
                new BufferedReader(new InputStreamReader(process.getInputStream()));
        String ligne;
        while ((ligne = reader.readLine()) != null) {
            System.out.println(ligne);
        }

        int exitCode = process.waitFor();
        System.out.println("nExited with error code : " + exitCode);

        String F = path + "\SomeFile.txt";
        System.out.println("------------------------file: " + F);
        File file = new File(F);
        Scanner scanner = new Scanner(file);
        //now read the file line by line...
        int lineNum = 0;
        while (scanner.hasNextLine()) {
            String line = scanner.nextLine();
            lineNum++;
            if (line.contains("Started server")) {
                response = true;
                System.out.println("-------------------------------------" + response.toString());
            }
        }
        ResponseEntity responseEntity = new ResponseEntity<Boolean>(response, HttpStatus.OK);
        return responseEntity;
    }

}

我希望上面的方法返回true值，但在返回值之前它被阻止了。

似乎 scanner.hasNextLine(( 无法从循环中退出，所以尝试如下：

     while (scanner.hasNextLine()) {
                String line = scanner.nextLine();
                lineNum++;
                if (line.contains("Started server")) {
                    response = true;
                    System.out.println("-------------------------------------" + response.toString());
     return new ResponseEntity<Boolean>(response, HttpStatus.OK);
                } else {
     return new ResponseEntity<Boolean>(response, HttpStatus.OK);
}
            }
