从Solr获取数据到JTable

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

You probably want to use some solr client to requests and handle response data.

But you can do it in simple HTTP GET request if you want to like so:

// get all documents
http://localhost:8983/solr/select?q=*:*

If you're using multiple cores, then you probably need to use:

// get all documents from core0
http://localhost:8983/solr/core0/select?q=*:*

You can read more about solr common query parameters here .

Answer 2

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);
