JDK1.7 HttpsURLConnection 调用HTTPS接口，发生如下报错：
main, WRITE: TLSv1.2 Handshake, length = 216
main, READ: TLSv1.2 Alert, length = 2
main, RECV TLSv1 ALERT: fatal, handshake_failure
javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

已经根据csdn搜到的在调用前指定了使用TLSv1.2协议了，如下：
SSLContext context = SSLContext.getInstance("TLSv1.2");
System.setProperty("https.protocols", "TLSv1.2,TLSv1.1,SSLv3");
context.init(null, null, null);
SSLContext.setDefault(context);
我看consol打印出来也是客户端发过去是TLSv1.2了，但为什么服务器返回还是有TLSv1的Alert？
jdk1.7 HttpsURLConnection 到底如何能调用https接口呢？POSTMAN就随意调用。。
用jdk1.7去访问https，怎么都不成功，要么成功后就是返回html代码，而不是json数据，主要因为jdk1.7默认https 请求是TLS1不支持TLS1.2。jdk1.7需要加入一个jar包：
