At present,i use solr 7.1,and want to integrate with spring boot ,but likely spring boot and solrj the highest version of the support is 5.5.but i use solr 7.1,and HttpSolrServer of solr is deprecated. Is it possible to perform the integration using solr 7.1
It is possible to upgrade individual versions of specifics libraries in spring-boot.
There is a file in spring boot that manages all it's preset versions found here: https://github.com/spring-projects/spring-boot/blob/1.5.x/spring-boot-dependencies/pom.xml
<solr.version>5.5.5</solr.version>
You could try overwrite this version by overwriting it in your own pom.xml
<properties>
<solr.version>7.1</solr.version>
</properties>
but beware this might break other stuff.
