究其原因，是JDK文件夹bin的中少了jce，下载一个复制进去就行了

打开以下网址，下载JCE压缩包：
http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

 

 

压缩包里有以下文件：

2、将压缩包解压，local_policy.jar和US_export_policy.jar这两个jar包放到$JAVA_HOME/jre/lib/security目录。因为目录下已有这两个文件，可以先备份，再覆盖。

mv $JAVA_HOME/jre/lib/security/local_policy.jar $JAVA_HOME/jre/lib/security/local_policy.jar.bak
mv $JAVA_HOME/jre/lib/security/US_export_policy.jar $JAVA_HOME/jre/lib/security/US_export_policy.jar.bak
cp local_policy.jar US_export_policy.jar $JAVA_HOME/jre/lib/security
