官网提供的javaSDK与DEMO中的HttpClient是否会引起fullgc
HttpClient httpClient = HttpClientBuilder.create()
.setConnectionManager(connManager)
.build();
String url = "https://" + domain + urlSuffix;
HttpPost httpPost = new HttpPost(url);
RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(readTimeoutMs).setConnectTimeout(connectTimeoutMs).build();
httpPost.setConfig(requestConfig);
StringEntity postEntity = new StringEntity(data, "UTF-8");
httpPost.addHeader("Content-Type", "text/xml");
httpPost.addHeader("User-Agent", USER_AGENT + " " + config.getMchID());
httpPost.setEntity(postEntity);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
return EntityUtils.toString(httpEntity, "UTF-8");
为什么HttpClient最后没有关闭,而且每次request都会创建一个HttpClient对象(是否需要使用CloseableHttpClient),创建HttpClient是一个很耗费资源的过程,这样在高并发下会不会出现fullgc,如果来不及回收的情况下,系统直接挂掉
