Spring Data Solr multiple cores and repository

Question

I have apache solr with multiple cores e.g. currency, country etc... So using Spring Data Solr I can retrieve information from one core. I have got this XML configuration ri

Answer 1

Spring Data now supports multiple cores with their respective repositories.

The multicoreSupport flag needs to be true in @EnableSolrRepositories annotation and the corresponding document needs to be told what core they belong to. Like:

@SolrDocument(solrCoreName = "currency")
public class Currency
{
    // attributes
}

the other class should be

@SolrDocument(solrCoreName = "country")
public class Country
{
    // attributes
}

The respective repositories should know what pojo they are working with.

public interface CurrencyRepository extends SolrCrudRepository
{
}

and

public interface CountryRepository extends SolrCrudRepository
{
}

and configuration should be

@Configuration
@EnableSolrRepositories(value = "com.package.name",multicoreSupport = true)
public class SolrConfig
{
    @Bean
    public SolrServer solrServer() throws Exception
    {
        HttpSolrServerFactoryBean f = new HttpSolrServerFactoryBean();
        f.setUrl("http://localhost:8983/solr");
        f.afterPropertiesSet();
        return f.getSolrServer();
    }

    @Bean
    public SolrTemplate solrTemplate(SolrServer solrServer) throws Exception
    {
        return new SolrTemplate(solrServer());
    }
}
