Spring config server not starting with keystore - spring

Question

trying to boot spring cloud config server with a keystore but am getting the following on startup:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'encryptionBootstrapConfiguration': Unsatisfied dependency expressed through field 'encryptor'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'textEncryptor' defined in org.springframework.cloud.bootstrap.encrypt.EncryptionBootstrapConfiguration$RsaEncryptionConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.crypto.encrypt.TextEncryptor]: Factory method 'textEncryptor' threw exception; nested exception is java.lang.NullPointerException
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'textEncryptor' defined in org.springframework.cloud.bootstrap.encrypt.EncryptionBootstrapConfiguration$RsaEncryptionConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.crypto.encrypt.TextEncryptor]: Factory method 'textEncryptor' threw exception; nested exception is java.lang.NullPointerException

at org.springframework.cloud.context.encrypt.EncryptorFactory.create(EncryptorFactory.java:34) ~[spring-cloud-context-1.1.9.RELEASE.jar:1.1.9.RELEASE]
The following options are used to start the component:
--spring.cloud.config.server.git.uri=http://mygit.com/alexander.lovett/service-discovery-demo.git
--spring.cloud.config.server.git.searchPaths=Software/config
--spring.rabbitmq.host=spring-bus
--management.security.enabled=false
--encrypt.keystore.location=file://C:/Users/607567487/BTTV/workspace/service-discovery-demo/Software/config-serverserver.jks
--encrypt.keystore.secret=changeme
--encrypt.keystore.password=letmein
--encrypt.keystore.alias=mytestkey
I've tried the location as file://C:/.../server.jks file:C:/.../server.jks and even put the jks on the classpath and tried classpath:server.jks
But still get the same error regardless.

Answer 1

Simple fix...
the properties should be encrypt.key-store.* not encrypt.keystore.*

Answer 2

I had the same issue, but a different cause. Here is a short description. In a nutshell, the problem was caused by ENCRYPT_KEY environment variable that triggered textEncryptor bean autoconfig with malformed KeyProperties. Spring failed to populate KeyProperties from the environment variable ENCRYPT_KEY causing NullPointerException. If encryption key is provided as system property -Dencrypt.key=123 then spring will have no problems configuring textEncryptor bean.
