Java Spring 怎麼非同步傳送post請求？

如果你跟我一樣用的Spring 4.0 版本或以上的話，最簡單的方式就是使用

AsyncRestTemplate

我用的是fastJson，來post Json 資料

原始碼如下,URL 是post 連結, 第二個引數是資料, 第三個引數可以不要

    public StringBuffer postHttpJsonDataAsyn(String URL, JSONObject jsonObject, final JSONObject responseJsonMap) throws IOException {
        // 傳送非同步post , 非阻塞, 傳送完無需等待結果返回
        AsyncRestTemplate client = new AsyncRestTemplate();
        ListenableFuture<ResponseEntity<String>> listenableFuture = client.postForEntity(URL, new HttpEntity<Object>(jsonObject), String.class);
        listenableFuture.addCallback(new SuccessCallback<ResponseEntity<String>>() {
            @Override
            public void onSuccess(ResponseEntity<String> result) {
                System.out.println("("+result.getStatusCode()+ ":"+result.getStatusCode().getReasonPhrase()+ "):"+result.getBody());
            }
        }, new FailureCallback() {
            @Override
            public void onFailure(Throwable ex) {
                System.out.println(ex);
            }
        });
        return new StringBuffer("finish postHttpJsonDataAsyn post");
    }

    @Override
    public StringBuffer postHttpStringDataAsyn(String URL, String postStr, JSONObject results) throws IOException {
        // 傳送非同步post , 非阻塞, 傳送完無需等待結果返回
        AsyncRestTemplate client = new AsyncRestTemplate();
        ListenableFuture<ResponseEntity<String>> listenableFuture = client.postForEntity(URL, new HttpEntity<Object>(postStr), String.class);
        listenableFuture.addCallback(new SuccessCallback<ResponseEntity<String>>() {
            @Override
            public void onSuccess(ResponseEntity<String> result) {
                System.out.println("("+result.getStatusCode()+ ":"+result.getStatusCode().getReasonPhrase()+ "):"+result.getBody());

            }
        }, new FailureCallback() {
            @Override
            public void onFailure(Throwable ex) {
                ex.printStackTrace();
                System.out.println(ex);
            }
        });
        return new StringBuffer("finish postHttpStringDataAsyn post");
    }
