如何为多个内核配置带有存储库的Spring Data Solr [英] How to configure Spring Data Solr with Repositories for multiple cores

问题描述

是否有使用带有多核支持的存储库的solr设置spring数据的详细而完整的解释?

Is there a detailed and complete explanation for setting up spring data with solr using repositories with multicore support?

推荐答案

唯一需要用于spring-data-solr的依赖项是

The only dependency that need to be used for spring-data-solr is

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-solr</artifactId>
    <version>1.5.2.RELEASE</version>
</dependency>

它会下载solrj依赖项，并且绝不能用更高版本的solrj覆盖. 同样，我们最好使用HttpSolrServer而不是EmbeddedSolrServer.

It downloads solrj dependency and this must not be overridden with later versions of solrj. Also It is always preferable to use HttpSolrServer over EmbeddedSolrServer which is what we will be working with.

Configuration类应如下所示:

The Configuration class should look like this:

@Configuration
@EnableSolrRepositories(value = "com.package.",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());
    }
}

文档实体应包含有关它们属于哪个核心的信息

The document entity should contain information about which core they belong to

@SolrDocument(solrCoreName = "core1")
public class Document1
{
    @Id
    @Field
    private String id;

    /**other attributes**/
}

另一个文件应该是

@SolrDocument(solrCoreName = "core2")
public class Document2
{
    @Id
    @Field
    private String id;

    /**other attributes**/
}

现在最好的部分是您已经完成.只需以简单的旧方法设置存储库就可以了

Now the best part is you are already done. Simply setting up repository in the plain old way does the trick

public interface SolrCore1Repository extends SolrCrudRepository<Document1,String>
{
    // optional code
}

另一个仓库就像

public interface SolrCore2Repository extends SolrCrudRepository<Document2,String>
{
    // optional code
}

一旦solr在指定的url上运行，并且其中包含根据pojo设置的字段，就完成了.

Once solr is running on the url specified and it has fields according to the pojo, you are done.
