Spring-cloud-config: Create failure analyzer when encrypt.keyStore.* properties in application.yml causes startup failure

[mjohns39]

Description of problem

If you try to set the encrypt.keyStore.* properties in application.yml, you get the following error:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2018-08-28 20:22:00.550 ERROR 31486 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter :

APPLICATION FAILED TO START

Description:

Field rsaProperties in org.springframework.cloud.config.server.config.EncryptionAutoConfiguration$KeyStoreConfiguration required a bean of type 'org.springframework.cloud.bootstrap.encrypt.RsaProperties' that could not be found.

Action:

Consider defining a bean of type 'org.springframework.cloud.bootstrap.encrypt.RsaProperties' in your configuration.

There is a question on stackoverflow of someone else having a similar issue.

Work-around

Move the encrypt.keyStore.* properties to bootstrap.yml

This is not a work around, it is the documented proper procedure to put these values in bootstrap

[mjohns39]

Why would adding the properties in application.yml cause an error then? If anything, shouldn't spring cloud just ignore the properties in application.yml?

[spencergibb]

Let's create a failure analyzer that suggests to move the properties to bootstrap.
