问题
I am using spring config server and spring security. I have followed the link https://cloud.spring.io/spring-cloud-config/multi/multi__spring_cloud_config_server.html I have added JCF in C:\Program Files\Java\jdk1.8.0_171\jre\lib\security folder. When I post localhost:8080/encrypt { "description": "The encryption algorithm is not strong enough", "status": "INVALID" } This response comes. Please let me know the issue.
回答1:
if you are getting {"description": "The encryption algorithm is not strong enough", "status": "INVALID" } response.The solution is just create bootstrap.properties file in config server and add encrypt.key="Secrete Key" property.

Disclaimer: I am running org.springframework.cloud:spring-cloud-config-server:2.0.6.RELEASE.
It's not just enought to enable unlimited crypto policy (btw, it is by default starting from jdk8.161), but you have to also provide (in case you want to use symmetric cryptography) encrypt.key property.
You can find it down the documentation: http://cloud.spring.io/spring-cloud-config/2.0.x/single/spring-cloud-config.html#_key_management
PS: Set it within bootstrap.properties.

bootstrap.properties are meant to be tracked under source control so i would rather reference the envcrypt.key value as an operating system environment variable.
For unix systems use export ENCRYPT_KEY=YOURKEY
Add this variable to one of start up files ~/bashrc, ~.profile or ~/.login to make it permanent
