SpringBoot整合Solr

    org.springframework.boot
    spring-boot-starter-data-solr
    2.4.11

必须指定solr的某个core

错误写法：http://localhost:8983/solr/

spring:
  data:
    solr:
      host: http://localhost:8983/solr/hotle_core

需要注入SolrClient

	//注入SolrClient
	@Resource
    private SolrClient solrClient;

    //添加操作
    @Test
    void contextLoads() throws IOException, SolrServerException {
        //新建索引
        SolrInputdocument document = new SolrInputdocument();
        //创建索引
        document.setField("id","123411");
        document.setField("name","小明");
        //添加索引
        solrClient.add(document);
        solrClient.commit();
    }

测试查询

result.get(“id”)获取的是solr配置文件中映射entity中的值

通过SolrQuery对象进行设置筛选条件进行查询

@Test
void querydocument() throws IOException, SolrServerException {
    SolrQuery query = new SolrQuery();
    //查询条件,默认所有查询
    query.setQuery("*:*");
    //查询结果的封装对象
    QueryResponse queryResponse = solrClient.query(query);
    //查询结果
    SolrdocumentList results = queryResponse.getResults();
    //查询到的数量
    long numFound = results.getNumFound();
    System.out.println(numFound);
    for (Solrdocument result : results) {
        System.out.println("id=>"+result.get("id"));
        System.out.println("article_abstract=>"+result.get("article_abstract"));
    }
}

安装使用Solr
