web service to retrieve data from solr - web-services

Question

how to write a rest web service to query data from solr server in java. I have the a java code to query from solr
CommonsHttpSolrServer server = null;
try
{
server = new CommonsHttpSolrServer("http://localhost:8080/solr/");
}
catch(Exception e)
{
e.printStackTrace();
}
SolrQuery query = new SolrQuery();
query.setQuery(solrquery);
query.set("rows",1000);
// query.setQueryType("dismax");
// query.setFacet(true);
// query.addFacetField("lastname");
// query.addFacetField("locality4");
// query.setFacetMinCount(2);
// query.setIncludeScore(true);
try
{
QueryResponse qr = server.query(query);
SolrDocumentList sdl = qr.getResults();
I need to get the same functionality in a web service by taking id as the query parameter.

If you just want to query the id passed as an parameter to the webservice -
String id = "100145";
String url = "http://localhost:8080/solr/core_name"; // core name needed if using multicore support
CommonsHttpSolrServer solrServer;
try {
solrServer = new CommonsHttpSolrServer(url);
ModifiableSolrParams qparams = new ModifiableSolrParams();
qparams.add("q", "id:"+id);
QueryResponse qres = solrServer.query(qparams);
SolrDocumentList results = qres.getResults();
SolrDocument doc = results.get(0);
System.out.println(doc.getFieldValue("id"));
} catch (Exception e) {
e.printStackTrace();
}
