找了半天终于解决了：

换掉本地jdk（安装目录jre\lib\security里的local_policy.jar,US_export_policy.jar）里面有一个jce的包，安全性机制导致的访问https会报错。

如本人安装的jdk需要替换的地方：1. C:\Program Files\Java\jdk1.8.0_102\jre\lib\security  2. C:\Program Files\Java\jre1.8.0_102\lib\security

下载地址: http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

目录 %JAVA_HOME%\jre\lib\security里的local_policy.jar,US_export_policy.jar
