我尝试设置一个基本的SolrRepository应用程序并在ApplicationContext加载期间出现此错误:

这是我的ConfigClass:

@Configuration
@PropertySource("classpath:sandbox.properties")
@ComponentScan("sandbox.solr")
@EnableSolrRepositories(basePackages = { "sandbox.solr.repository" }, multicoreSupport = true)
public class StreamingSolrConf {

    @Resource
    private Environment env;

    @Bean
    public SolrServer solrServer() {
        return new HttpSolrServer(env.getRequiredProperty("solr.server.url"));
    }

    @Bean
    public SolrTemplate …

我需要将此类数据插入到 solr 服务器。

{
    "id":"09123"
    "firstName": "Harshana651175279",
    "lastName": "Samaranayake332146645",
    "department": {
            "id":"001",
            "depName":"dep01"        
        }
}

这些是我用于插入数据的 POJO。

public class SolrCustomer {

    @Id
    @Indexed
    private String id;
    @Field
    @Indexed
    private String firstName;
    @Field
    @Indexed
    private String lastName;
    @Field
    private Department department;

    //getters n setters
}

public class Department {

    @Id
    @Indexed
    private String id;
    @Field
    @Indexed
    private String departmentName;

    //getters n setters
}

没有部门数据它工作正常。但无法作为嵌套文档插入。当我尝试时，就像这样插入

{
    "firstName": "Harshana651175279",
    "lastName": "Samaranayake332146645",
    "department": [
        "org.ftm.solr.domain.Department@479c1814"
    ],
    "id": "2e204ab3-772d-4af1-a2be-866e21206ecd",
    "_version_": 1536317096485453800
}

这是我为此配置的架构。

<field name="department" …

当我直接在 Intellij 中运行集成测试时，测试成功运行。这是我对嵌入式服务器的 bean 定义。我添加了 destroyMethod 并且它没有效果。

我正在使用spring MVC开发一个Web应用程序,我使用tomcat托管它.我有一个要求,我想将apache-solr集成到我的搜索引擎.

我尝试在互联网上查找各种教程,但找不到合适的解释步骤.

所以我的要求是

1. 如何使用maven依赖(我使用tomcat来托管服务器)在Spring MVC中集成apache solr
2. 使用solr添加数据文件的基本教程
3. 如何集成它以从我的数据库中获取数据.我正在使用hibernate来映射我的数据库表.

经过一些教程后,我认为spring-data-solr适用于spring MVC.

PS我是上述所有技术的新手.

我正在编写一个与 Solr 通信的 Web 应用程序，我正在使用 Spring Data Solr + SolrJ 来获取 Java 中的信息。

对于 Solr 查询，我使用 (e)DisMax 和一些选项（现在，也许以后我需要添加其他内容）：

SolrQuery query = new SolrQuery();
        
query.set("q", terms);
query.set("pf", "text^100");
query.set("qf", "text");
query.set("defType", "edismax");
        
query.setStart(pageable.getOffset());
query.setRows(pageable.getPageSize());
        
query.setHighlight(true).setHighlightSnippets(10);
query.setParam("hl.fl", "text");

对于这种结构，我以这种方式构建了一个 bean

@SolrDocument
public class Document {
    
    @Field
    private String id;
    
    @Field
    private String text;
    
    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text …

我正在尝试使用 spring data solr 实现过滤器搜索。我有以下过滤器类型，并且都有一组过滤器。

1. A
   • (1,2,3) 中的 aa
   • ab 之间 (2016-08-02 至 2016-08-10)
2. 乙
   • 巴 (2,3,4)
   • bb 之间（550 至 1000）

我想使用 Spring data solr 实现的 Solr 查询是：

q=*:*&fq=(type:A AND aa:(1,2,3) AND ab:[2016-08-02 TO 2016-08-10]) OR (type:B AND ba:(2,3,4) AND bb:[550 TO 1000])

我不确定如何对某种类型的过滤器的多个子句进行分组，然后使用 OR 运算符。

提前致谢。

我找到了一篇关于 spring-data 反应式存储库的博客文章。有人提到，它目前支持 MongoDB、Apache Cassandra 和 Redis。

我们将在我们的反应式（基于 vert'x）架构中使用 spring-data-solr 存储库。

是否有可能在这种类型的存储库中轻松获得反应式支持？实施自己的反应式 solr 存储库需要多少努力？

我正在使用带有Solr 4.4.0和Spring 3.2.4.RELEASE的spring-data-solr 1.0.0.RELEASE编写基于Spring MVC的Search API.

我能够运行基本查询但无法找到任何好的示例如何返回得分和距离:结果中的geodist().

我知道我可以使用查询来获取Solr的结果

http://localhost:8983/solr/events/select?q=*:*&spatial=true&pt=51.435872%2C-0.427529&sfield=position&d=20&facet=true&facet.mincount=1&facet.limit=-1&facet.field=categoryIds&fl=score,*,distance:geodist()&sort=geodist()+asc

但我不知道如何使用spring-data-solr从Solr返回得分和距离属性.我试过以下代码

FacetQuery search = new SimpleFacetQuery();

Criteria conditions;// = new Criteria();
if(StringUtils.isNotBlank(searchCriteria.getSearchString()))
        conditions = new Criteria(EventDocument.FIELD_EVENT).contains(searchCriteria.getSearchString());

if(searchCriteria.isLocationKnown()){
        conditions.and(new Criteria(EventDocument.FIELD_POSITION).within(new GeoLocation(searchCriteria.getLatitude(), searchCriteria.getLongitude()), new Distance(searchCriteria.getDistance(), Distance.Unit.MILES)));
        conditions.and(new Criteria(CommonParams.FL).is("score,distance:geodist(),*"));
    } else{
        conditions.and(new Criteria(CommonParams.FL).is("score,*"));
    }

search.addCriteria(conditions);
FacetPage page = solrTemplate.queryForFacetPage(search, EventDocument.class);

但得到以下例外:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.data.solr.UncategorizedSolrException: undefined field fl; nested exception is org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: undefined field fl

我正在尝试执行一个查询,就像从文档中检索一个特定字段,我在执行查询时没有获取运行时错误,但我没有得到我应该从查询中检索的3个字段,只是日期和原点,但没有变量,应该返回所有变量的变量都是空值.我如何选择我只想在查询中检索的字段？

目前我的查询如下所示:

  @Query(value = "id:?0", fields = {"?1","date","origin"})
   List<Data> getRecord(String id,String field);
