HttpClient get请求验证URL是否正常

项目开发中用org.apachemons.httpclient.HttpClient get请求验证URL是否正常，使用jdk1.7 80版本 ，大量地址被验证，频繁失败， 日志 报错内容如下：

借鉴网上很多大佬的出现问题的解说，

 1、jre的加密策略原因，导致SSL请求还没发出去，客户端就自己断了连接。

2、说是TLS版本的问题，jdk1.7默认的TLS版本是1.0，将TLS版本改成1.1或者1.2就行。

解决问题有如下：

1、代码增加：System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");验证了，无效。

2、更换jdk1.7 131版本及以上，TLS1.2 For JRE 1.7.0_131-b31 in Oracle site : TLSv1.2 and TLSv1.1 are now enabled by default on the TLS client end-points. This is similar behavior to what already happens in JDK 8 releases.，验证后，简直不要太好哦。。非常感谢
