    Repository take solrtemplate to execute solr operations. Since we have multiple cores so we need to create multiple template and multiple repositories for each core. Following example explains it with 2 solr core

    Repository and custom implementation for core1:

    public interface ICore1CustomDao {
    
    	  List<Core1> findCore1Data();
    }
    
    public interface Core1Repository extends SolrCrudRepository<Core1, String> {
    
    }
    
    public class Core1DaoImpl implements ICore1CustomDao {
    
    	@Autowired
        private SolrTemplate core1Template;
    
        public EventRepositoryImpl(SolrTemplate core1Template) {
            this.core1Template = core1Template;
        }
    
        @Override
        public List<Core1> findCore1Data() {
            return core1Template.queryForPage(new SimpleQuery("*:*"), Core1.class);
        }
    
    }

    Do same for Core2 repositories.

    Configure solr as:

    @Configuration
    public class Application {
    	
    	@Bean
    	public SolrServerFactory solrServerFactory() {
    		return new MulticoreSolrServerFactory(new HttpSolrServer("http://localhost:8983/solr"));
    	}
    	
    	@Bean
    	public SolrTemplate core1Template() throws Exception {
    		SolrTemplate solrTemplate = new SolrTemplate(solrServerFactory());
    	    solrTemplate.setSolrCore("core1");
    	    return solrTemplate;
    	}
    	
    	@Bean
    	public Core1Repository core1Repository() throws Exception {
    	    return new SolrRepositoryFactory(core1Template())
    	      .getRepository(Core1Repository.class, new Core1DaoImpl(core1Template()));
    	}
    	
    	@Bean
    	public SolrTemplate core2Template() throws Exception {
    		SolrTemplate solrTemplate = new SolrTemplate(solrServerFactory());
    	    solrTemplate.setSolrCore("core2");
    	    return solrTemplate;
    	}
    	
    	@Bean
    	public Core2Repository core2Repository() throws Exception {
    	    return new SolrRepositoryFactory(core2Template())
    	      .getRepository(Core2Repository.class, new Core2DaoImpl(core2Template()));
    	}
    	
    }

    Its done.
