这个是jdk导致的，jdk里面有一个jce的包，安全性机制导致的访问https会报错，官网上有替代的jar包，换掉就好了

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

JDK7 http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

JDK8 http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
