parameterized proxy URL matching query does not work with Spring Boot

[etasens]

Trying to set this up where the solr core is parameterized in a Spring Boot Application. The redirect url is
http://444.44.444.444:8983/solr/{_core}/select

This throws exception
java.net.URISyntaxException: Illegal character in path at index 32: http://444.44.444.444:8983/solr/{_core}/select

Is there a quick way around this?

Sorry but you'll have to look at this in a debugger. I don't have time. Those squiggly brackets I recall are the syntax for the parameterized proxy and so shouldn't be put into a URI object. So something is going wrong.
