如何使用原始弹簧数据索尔在嵌入式 solr 上配置多个内核

Question

我想在我的Solr 5.5.0嵌入式服务器环境中添加另一个内核。"在我的世界里"，我创建了一个嵌入式服务器，让 spring-data 加载核心配置。但是使用我的解决方案，似乎所有数据都进入默认的核心"collection1"。到目前为止，我在弹簧引导旁边找不到示例。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，您可以执行类似操作，而不是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嵌入式解决方案客户端或独立客户端。您可以根据配置文件将其更改为执行(自动连线环境并检查配置文件(
