Question

I new in Solr. I can add data to Solr from application, but I want to get data from Solr to my Java desktop application.

How can I get data from Solr ("http://localhost:8983/solr")?

Answer 1

Solrj is the easiest way to go. It’s the solr java client library.
Add it as a dependency to your project, then write a pojo with all the fields that you want to get back from Solr. Annotate each field with the solrj @Field annotation, then send your query to Solr like this:

SolrServer solrServer = new HttpSolrServer("htp://localhost:8080/solr/core0");
QueryResponse response = solrServer.query(new SolrQuery(query));
List<Pojo> pojos = response.getBeans(Pojo.class);
