Quel est le chemin de classe pour le serveur solr intégré au démarrage de printemps?

Question

J'essaie d'utiliser un serveur solr intégré dans mon application de démarrage au printemps. Ma configuration est la suivante:

package ch.*.rest.config; 
import java.io.IOException; 
import javax.xml.parsers.ParserConfigurationException; 
import org.apache.solr.client.solrj.SolrClient; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.data.solr.core.SolrOperations; 
import org.springframework.data.solr.core.SolrTemplate; 
import org.springframework.data.solr.repository.config.EnableSolrRepositories; 
import org.springframework.data.solr.server.support.EmbeddedSolrServerFactory; 
import org.xml.sax.SAXException; 

@Configuration 
@EnableSolrRepositories 
public class SolrContext { 

    @Bean 
    public SolrClient solrClient() throws ParserConfigurationException, IOException, SAXException { 
     EmbeddedSolrServerFactory factory = new EmbeddedSolrServerFactory("classpath:com/acme/solr"); 
     return factory.getSolrClient(); 
    } 
    @Bean 
    public SolrOperations solrTemplate() throws ParserConfigurationException, IOException, SAXException { 
     return new SolrTemplate(solrClient()); 
    } 
} 

Avec gradle j'inclure les dépendances suivantes

compile('org.apache.solr:solr-core:5.5.4') 
compile('org.springframework.data:spring-data-solr:2.1.4.RELEASE') 

L'exécution de l'application renvoie l'exception suivante:

java.io.FileNotFoundException: class path resource [com/acme/solr] cannot be resolved to absolute file path because it does not exist

Il est évident que le classpath com/Acme/solr n'est pas trouvé. Comment puis-je savoir quel est le chemin réel de la classe?

Pour la configuration j'ai suivi http://docs.spring.io/spring-data/solr/docs/2.1.x/reference/html/#solr.annotation

Answer 1

De la documentation:

public EmbeddedSolrServerFactory(String solrHome) 
         throws ParserConfigurationException, 
          IOException, 
          SAXException 

Paramètres:

solrHome - Toute expression de chemin valide pour une utilisation avec ResourceUtils qui pointe vers le solr.solr .home directory

Cela signifie que vous devez créer un Solr H ome (et mettez les configurations de solr dedans là) dans le dossier de ressource pour gradle pour le ramasser. Ensuite, vous devez transmettre ce chemin à l'usine Solr intégrée. J'espère que ça aide
