原因：

默认自带的policy.jar不支持gpg加密的功能。需要替换jar

方法1：  修改java.security

先找到java的安装位置

windows下查看版本：（默认安装路径安装就不需要去配环境变量了）

1 java -version

windows下查看安装路径：

1 java -verbose

找到 jre/lib/security/java.security

检查是否有写入的权限为（644）没有的话授权

vi  jre/lib/security/java.security

新增

security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider

保存完成在把文件的权限改为(444)

2、方法2

替换

jre/lib/security/policy/limited/local_policy.jar

jre/lib/security/policy/limited/US_export_policy.jar

并修改为权限（644）
