https 之间调用Certificate for

之前的httpclient是这样创建的

PoolingClientConnectionManager conMgr = new PoolingClientConnectionManager();
DefaultHttpClient httpclient = new DefaultHttpClient(conMgr);

改为：

SSLConnectionSocketFactory scsf = new SSLConnectionSocketFactory(SSLContexts.custom().loadTrustMaterial(null, new TrustSelfSignedStrategy()).build(), NoopHostnameVerifier.INSTANCE);

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(scsf).build();

发现以下错误时，解决方法同上
provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
