Ryan McKinley commented on SOLR-20:
-----------------------------------
I have dramatically reworked the client code to fit with the pluggable
ContentStream model in SOLR-104. This version makes it easy to
customize/extend the request/response behavior. Once it stabilizes and is
better tested, I'll upload a zip, but for now, you can preview it:
http://svn.lapnap.net/solr/solrj/
Major changes:
* it is based on commons-httpclient-3.0.1.jar
* I'm using wt=JSON rather then XML. (It maps to a hash easier)
* I moved some of the common classes to o.a.s.util. Hopefully the core classes
will be refactored to make it easier to share some classes
* handles multiple ContentStreams using multi-part form upload
* Got rid of the SolrDocumentable/SolrDocumented distinction. -- now there is
only SolrDocument()
* You can define and automatically build a solr document with annotations
* Includes a first draft for a HibernateEventListener. When stuff is
added/updated/deleted, it gets sent to solr. (Note, this class should probable
not be in the main client as the hibernate prerequisite libraries are
substantial - I've included them because its what i need to have working soon)
When this is more stable, it will be something similar to a Compass
Hibernate3GpsDevice
(http://www.opensymphony.com/compass/versions/1.1RC1/html/gps-hibernate.html)
The key interfaces are:
public interface SolrClient
{
public abstract SolrResponse process( final SolrRequest req );
}
public interface SolrRequest
{
public String getMethod();
public String getHandlerPath();
public RequestParams getParams();
public Collection<ContentStream> getContentStreams();
public SolrResponse parseResponseBody(InputStream in);
public SolrResponse execute(SolrClient solr);
}
- - - - - - -
Here is some sample usage:
SolrClient client = new CommonsHttpSolrClient(
new URL("http://localhost:8983/solr/";) );
// Set up a simple query
SolrQuery query = new SolrQuery();
query.setQuery( "solr" );
query.addFacetField( "cat" );
query.setFacetLimit( 15 );
query.setQuery( "video" );
query.setShowDebugInfo( true );
QueryResponse rsp = query.execute( client );
for( ResultDoc doc : rsp.getDocs() ) {
System.out.println( doc.get( "name" ) );
System.out.println( doc.getScore() );
System.out.println( doc.getExplain() );
}
SimpleSolrDoc doc = new SimpleSolrDoc();
doc.setField( "id", "xxx" );
doc.setField( "price", 12.34f );
doc.setField( "cat", new String[] { "aaa", "bbb", "ccc" } );
new AddDocuments( doc ).execute( client );
new CommitIndex().execute( client );

This also includes a utility to make solr documents from annotations. Given
the class:
@SolrSearchable( boost=2.0 )
public class Example
{
@SolrSearchable
public String getName()
{
return "hello"
}
@SolrSearchable( name="cat", boost=3 )
public String getSomeOtherName()
{
return "there"
}
}
The DocumentBuilder can automatically make:
<doc boost="2.0">
<field name="name">hello</field>
<field name="cat" boost="3">there</field>
</doc>

There are a few parts of the API i think are awkward, I'd love any feedback /
review you may have.
