我是靠谱客的博主 苗条菠萝,最近开发中收集的这篇文章主要介绍java httpclient 阻塞_java – Httpclient 4.3阻塞连接池,觉得挺不错的,现在分享给大家,希望可以做个参考。

概述

当我使用httpclient 4.3如下

static {

try {

SSLContextBuilder builder = new SSLContextBuilder();

builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());

SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build());

CookieSpecProvider easySpecProvider = new CookieSpecProvider() {

public CookieSpec create(HttpContext context) {

return new BrowserCompatSpec() {

@Override

public void validate(Cookie cookie, CookieOrigin origin) throws MalformedCookieException {

// Oh, I am easy

}

};

}

};

Registry r = RegistryBuilder. create()

.register(CookieSpecs.BEST_MATCH, new BestMatchSpecFactory())

.register(CookieSpecs.BROWSER_COMPATIBILITY, new BrowserCompatSpecFactory())

.register("easy", easySpecProvider).build();

RequestConfig requestConfig = RequestConfig.custom().setConnectionRequestTimeout(5000)

.setSocketTimeout(10000).setConnectTimeout(10000).setCookieSpec("easy").setRedirectsEnabled(false)

.build();

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();

cm.setMaxTotal(100);

cm.setDefaultMaxPerRoute(10);

client = HttpClients.custom().setConnectionManager(cm).setDefaultCookieSpecRegistry(r)

.setSSLSocketFactory(sslsf).setDefaultRequestConfig(requestConfig).build();

} catch (Exception e) {

logger.error("http client init fail!", e);

}

}

public static String execute(HttpRequest httpRequest) {

CloseableHttpResponse response = null;

HttpGet httpGet = null;

HttpEntity httpEntity = null;

try {

httpGet = new HttpGet(httpRequest.getUrl());

httpGet.setHeader("Connection", "close");

if (httpRequest.isUseGzip()) {

httpGet.addHeader("Accept-Encoding", "gzip,deflate,sdch");

}

if (!StringUtils.isEmpty(httpRequest.getContentType())) {

httpRequest.setContentType(httpRequest.getContentType());

}

httpGet.addHeader("User-Agent",

"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63");

response = client.execute(httpGet);

httpEntity = response.getEntity();

byte[] bytes = null;

try {

bytes = EntityUtils.toByteArray(httpEntity);

} catch (Exception e) {

return null;

}

if (response.getStatusLine().getStatusCode() != 200) {

logger.warn("error! StatusCode: " + response.getStatusLine().getStatusCode() + ", url: "

+ httpRequest.getUrl());

return null;

}

@SuppressWarnings("deprecation")

String charset = EntityUtils.getContentCharSet(httpEntity);

if (StringUtils.isEmpty(charset)) {

Matcher match = charsetPatterm.matcher(new String(bytes));

if (match.find()) {

charset = match.group(1);

}

}

if (!StringUtils.isEmpty(charset)) {

String strUtf8 = new String(new String(bytes, charset).getBytes(), GlobalConfig.ENCODING);

return StringEscapeUtils.unescapeHtml4(strUtf8);

}

} catch (Exception e) {

logger.error("error! url [" + httpRequest.getUrl() + "]", e);

} finally {

try {

if (httpEntity != null) {

EntityUtils.consume(httpEntity);

}

if (response != null) {

response.close();

}

if (httpGet != null) {

httpGet.abort();

}

} catch (Exception e) {

// ignore

}

}

return null;

}
