Spring cloud data flow custom application properties

Question

I created a custom spring cloud data flow application. I would like to create a stream with it and put some application properties in it, as we can add for the provided appl

Answer 1

For the custom application properties, you can make sure if you follow Spring Boot configuration properties configuration correctly. You can see some of the examples from the out of the box apps here

I am not sure which version of SCDF do you use. If you are on the release before SCDF 2.x, then the name of the whitelist properties needs to be spring-configuration-metadata-whitelist.properties as the whitelist properties file with the name dataflow-configuration-metadata-whitelist.properties is supported only from SCDF 2.x.

Also, make sure to place the whitelist properties file into /META-INF directory under classpath (src/main/resources directory) for example here.

Regarding the documentation, please follow the instructions mentioned here in the SCDF documentation.
