Looks like the problem above is due to the constructor. There is something is spring data that doesn't like this class to have a constructor.

I can guess that spring is using reflection and default constructor to create the instance. You second example doesn’t have default constructor and probably that’s why it doesn’t work.

Someone else pointed to me that Spring hates final classes. I have to try using open classes on that.

or use all-open plugin

the spring-boot plugin opens all annoted classes (at least the @Service, @Component, @Repository ones. I’m not sure about @Document/SolrDocument)

yep that's what I ended up using
