定位是 AES-ECB解密JCE无限制权限策问题

Java版本

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (IcedTea 3.12.0) (Alpine 8.212.04-r0)
OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)

进入容器查看Java路径

echo $JAVA_HOME

 找到policy路径

 

docker替换jar包

# jre替换local_policy.jar和US_export_policy.jar JCE无限制权限策
COPY  UnlimitedJCEPolicyJDK8/local_policy.jar /usr/lib/jvm/java-1.8-openjdk/jre/lib/security/policy/limited/local_policy.jar
COPY  UnlimitedJCEPolicyJDK8/US_export_policy.jar /usr/lib/jvm/java-1.8-openjdk/jre/lib/security/policy/limited/US_export_policy.jar
COPY  UnlimitedJCEPolicyJDK8/local_policy.jar /usr/lib/jvm/java-1.8-openjdk/jre/lib/security/policy/unlimited/local_policy.jar
