1、windows10下配置solr环境，将solr官网下载好的压缩包解压到指定目录，solr的项目结构如下

cmd进入server/solr目录下启动solr服务：

浏览器访问：http://localhost:8983/solr

创建核心文档

2、项目集成：

pom.xml文件添加依赖

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

application.yml配置

data:
        solr:
          host: http://192.168.168.224:8983/solr/searchList

业务代码：

solr工具类

@Component
    public class SolrUtils {
        private SolrClient solrClient;
        
        private SolrQuery  solrQuery;
        @Autowired
        public SolrUtils(SolrClient solrClient) {
            this.solrClient = solrClient;
            solrQuery = new SolrQuery();
        }
    
        /**
         * 向solr文档中添加对象
         * @param data
         * @throws IOException
         * @throws SolrServerException
         */
        public void addSolrPO(SolrSearchPO data) throws IOException, SolrServerException {
            solrClient.addBean(data);
            solrClient.commit();
        }
    
        /**
         * solr查询
         * @param key  关键字
         * @param page  
         * @param row
         * @return
         * @throws IOException
         * @throws SolrServerException
         */
        public List<SolrSearchPO> queryList(String key,int page,int  row) throws IOException, SolrServerException {
            List<SolrSearchPO> list=new ArrayList<>();
            solrQuery.setQuery(key);
            solrQuery.setStart(page);
            solrQuery.setRows(row);
            //设置高亮字段
            solrQuery.setHighlight(true);
            solrQuery.addHighlightField("name,title");
            solrQuery.setHighlightSimplePre("<font color='red'>");
            solrQuery.setHighlightSimplePost("</font>");
            QueryResponse query = solrClient.query(solrQuery);
            // 文档结果集
            SolrDocumentList docs = query.getResults();
            SolrSearchPO solrSearchPO;
            for (SolrDocument s : docs) {
                solrSearchPO = new SolrSearchPO();
                solrSearchPO.setId(s.getFirstValue("id").toString());
                solrSearchPO.setName(s.getFirstValue("name").toString());
                solrSearchPO.setTitle(s.getFirstValue("title").toString());
                solrSearchPO.setContent(s.getFirstValue("content").toString());
                list.add(solrSearchPO);
            }
            return list;
        }
    
        /**
         * 删除
         * @throws IOException
         * @throws SolrServerException
         */
        public void delDoc() throws IOException, SolrServerException {
            solrClient.deleteByQuery("*:*");
            solrClient.commit();
        }
    }

测试

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class SolrTest {
    
        private Logger logger = LoggerFactory.getLogger(SolrTest.class);
    
        @Autowired

            try {
                allTestPo = testService.findAllTestPo(3);
                for (TestPO t : allTestPo) {
                    solrSearchPO = new SolrSearchPO();
                    solrSearchPO.setId(String.valueOf(t.getId()));
                    solrSearchPO.setName(t.getName());

                    solrUtils.addSolrPO(solrSearchPO);
                }
    
            } catch (Exception e) {
                e.printStackTrace();
                logger.error("添加错误--->"+e.toString());
            }
    
    
        }
    
        @Test
        public void queryList() {
            try {
                List<SolrSearchPO> solrSearchPOS = solrUtils.queryList("*:*", 0, 10);
                logger.info("搜索结果集长度---------->size=" + solrSearchPOS.size());
                for (SolrSearchPO s : solrSearchPOS) {
                    logger.info(s.toString());
                }
            } catch (IOException | SolrServerException e) {
                e.printStackTrace();
                logger.info("搜索失败------>e=" + e.toString());
            }
        }
    
        @Test
        public void del() {
            try {
                solrUtils.delDoc();
                logger.info("删除solr索引成功");
            } catch (IOException | SolrServerException e) {
