如何使用原始 spring-data-solr 在嵌入式 solr 上配置多个内核

Question

我想为我的 Solr 5.5.0 嵌入式服务器环境添加另一个核心。 "In my world" 我创建了一个嵌入式服务器并让 spring-data 加载核心配置。但是在我的解决方案中，似乎所有数据都进入了默认核心 "collection1"。到目前为止，我找不到 spring-boot 旁边的示例。但这不是一个选择。

到目前为止，我的配置如下所示：

@Import({
    AppctxSolrEmbedded.class,
    AppctxSolrHttp.class
})
@EnableSolrRepositories(value = "de.my.application.*.repository", multicoreSupport = true)
@Configuration
public class AppctxSolr {

    public @Bean SolrTemplate solrTemplate(
            @Named("solrClient") SolrClient solrClient) {
        return new SolrTemplate(solrClient, "collection1");
    }

    public @Bean SolrTemplate operatorSolrTemplate(
            @Named("solrClient") SolrClient solrClient) {
        return new SolrTemplate(solrClient, "operator1");
    }
}

@Dev @Qual @RemoteDev
@Configuration
public class AppctxSolrEmbedded {

    @Bean
    public EmbeddedSolrServerFactoryBean solrClient(
            @Value("${solr.server}") String solrHome) {
        EmbeddedSolrServerFactoryBean factory = new EmbeddedSolrServerFactoryBean();
        factory.setSolrHome(solrHome);
        return factory;
    }
}

@Prod
@Configuration
public class AppctxSolrHttp {

    @Bean
    public HttpSolrClientFactoryBean solrClient(
            @Value("${solr.server}") String baseURL) {
        HttpSolrClientFactoryBean factory = new HttpSolrClientFactoryBean();
        factory.setUrl(baseURL);
        return factory;
    }
}

这是我的做法

@Configuration
@EnableSolrRepositories(multicoreSupport = true)
public class MulticoreSolrConfiguration {

  @Autowired
  private SolrClient solrClient;

  @Bean
  public SolrOperations solrTemplate() throws ParserConfigurationException, SAXException, IOException {
    return new SolrTemplate(this.solrClient);
  }

  @Bean
  public MulticoreSolrClientFactory multicoreSolrClientFactory()
      throws ParserConfigurationException, SAXException, IOException {
    return new MulticoreSolrClientFactory(this.solrClient, "operator1", "collection1");
  }

  @Bean(name = "operatorSolrClient")
  public SolrClient operatorSolrClient() throws IOException, SAXException, ParserConfigurationException {
    return this.multicoreSolrClientFactory().getSolrClient("operator1");
  }

  @Bean(name = "operatorSolrTemplate")
  public SolrTemplate operatorSolrTemplate() throws IOException, SAXException, ParserConfigurationException {
    return new SolrTemplate(this.operatorSolrClient());
  }
}

  @Bean(name = "collectionSolrClient")
  public SolrClient collectionSolrClient() throws IOException, SAXException, ParserConfigurationException {
    return this.multicoreSolrClientFactory().getSolrClient("collection1");
  }

  @Bean(name = "collectionSolrTemplate")
  public SolrTemplate collectionSolrTemplate() throws IOException, SAXException, ParserConfigurationException {
    return new SolrTemplate(this.collectionSolrClient());
  }
}

然后您可以像这样代替 AppctxSolrEmbedded 和 AppctxSolrHttp

@Configuration
class SolrConfiguration {

  private final SolrProperties solrProperties; // Has details about solr host, port, directory .....

  @Autowired
  public SolrConfiguration(final SolrProperties solrProperties) {
    this.solrProperties = solrProperties;
  }

  @Bean
  SolrClient solrClient() {
    final SolrClient solrClient;
    if (this.solrProperties.isEmbedded()) {
      solrClient = createEmbeddedSolrClient();
    } else {
      solrClient = createStandaloneSolrClient();
    }

    return solrClient;
  }

  private SolrClient createEmbeddedSolrClient() {
    final String solrConfigurationFolder = this.solrProperties.getSolr().getHome();

    final EmbeddedSolrServerFactoryBean factoryBean = new EmbeddedSolrServerFactoryBean();
    factoryBean.setSolrHome(solrConfigurationFolder);

    return factoryBean.getSolrClient();
  }

  private SolrClient createStandaloneSolrClient() {
    final String solrUrl = this.solrProperties.getHost();

    return new HttpSolrClient(solrUrl);
  }
}

如您所见，我正在根据某些属性集创建 embeddedsolrclient 或 standaloneclient。您可以将其更改为基于配置文件（Autowire 环境并检查配置文件）
