布满荆棘的人生 2023-10-11 11:09 43阅读 0赞

**一、加入依赖：**

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

**二、在application.yml中：**

spring:
      data:
        solr:
          host: http://192.168.2.155:8983/solr/ik_core

**三、测试：**

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class MystoreSearchServiceApplicationTests {
    
        @Autowired
        private SolrClient client;
    
        @Test
        public void testQueryDataByHighLighting() {
            SolrQuery query = new SolrQuery();
            //设置查询内容
            query.setQuery("双卡");
            //设置分页
            query.setStart(0);
            query.setRows(10);
            //设置复制域
            query.set("df", "t_product_keywords");
    
            //开启高亮
            query.setHighlight(true);
            //添加高亮字段
            query.addHighlightField("t_product_name");
            //设置高亮的前缀和后缀
            query.setHighlightSimplePre("<span style='color:red;'>");
            query.setHighlightSimplePost("</span>");
    
            try {
                QueryResponse response = client.query(query);
                // 结果集
                SolrDocumentList results = response.getResults();
                // 高亮部分
                Map<String, Map<String, List<String>>> highlighting = response.getHighlighting();
                for (SolrDocument result : results) {
                    Object id = result.getFieldValue("id");
                    // 根据id拿当前字段的高亮部分；
                    Map<String, List<String>> stringListMap = highlighting.get(id);
                    if (stringListMap != null) {
                        List<String> t_product_name = stringListMap.get("t_product_name");
                        String s = t_product_name.get(0);
                        System.out.println(s);
                    }
                }
            } catch (SolrServerException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    
        @Test
        public void testQueryData() {
            SolrQuery query = new SolrQuery();

            try {
                QueryResponse response = client.query(query);

            } catch (SolrServerException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    
        @Test
        public void testDeleteData() {

            try {

            document.addField("id", "003");
            document.addField("t_product_name", "huawei p30 牛逼 荣耀之最 双卡双待");
