I'll start off this reply by saying that I am in no way an expert on
Spring libraries. I've used them, but there's plenty that I do not know.
I think that if you're using spring-data-solr, then ONLY use
spring-data-solr. Do not try to load SolrJ itself as a dependency ...
it will be pulled in automatically. Using a different version of SolrJ
than spring-data-solr expects might break spring-data-solr. Accessing
SolrJ objects and methods directly in a way not explicitly recommended
by spring-data-solr might also cause problems.
When trying to use SolrJ directly and not through spring-data-solr, this
is required in the @SpringApplication annotation:
@SpringBootApplication(exclude = { SolrAutoConfiguration.class })
Yes, I have needed this in one of my own Spring Boot projects. Without
that, I got some WEIRD exceptions from my program. I no longer recall
what they were -- so I have no idea if the exceptions you're getting are
the same thing or not.
There may be other subtleties involved with Spring classes and SolrJ
that I have never personally encountered. Since you're using
spring-data-solr, you really need to talk to Spring first about any
problems you encounter, and only come to us if Spring says you need to.
