在新的Gmail API中批量提取电子邮件

BatchRequest b = service.batch();//callback function. (Can also define different callbacks for each request, as required)JsonBatchCallback<Thread> bc = new JsonBatchCallback<Thread>() {    @Override    public void onSuccess(Thread t, HttpHeaders responseHeaders) throws IOException {        System.out.println(t.getMessages().get(0).getPayload().getBody().getData());    }    @Override    public void onFailure(GoogleJsonError e, HttpHeaders responseHeaders) throws IOException {    }};// queuing requests on the batch requestsfor (Thread thread : threads) {    service.users().threads().get("me", threads.getId()).queue(b, bc);}b.execute();
