SSLConnectionSocketFactory sslFactory = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
HttpClientConnectionManager connMgr = PoolingHttpClientConnectionManagerBuilder.create().setSSLSocketFactory(sslFactory).build();
return HttpClients.custom().setConnectionManager(connMgr).setUserAgent("MyService").build();

只要构造SSLConnectionSocketFactory对象的时候传入new NoopHostnameVerifier()就可以了，否则httpclient5会校验启动的桩的ip和证书的ip是否一致，不一致会报
