SpringBoot+solr

1.配置application.yml

　　spring.data.solr.host: http://192.168.6.168:8080/solr/ciri_core

2.引入jar包

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

3.使用solrj增删改查

@Service
public class SolrServiceImpl implements SolrService {

    @Autowired
    private SolrClient solrClient;
    @Autowired
    private SolrMapper solrMapper;

    public List<SolrDto> query() throws IOException, SolrServerException {
        SolrQuery solrQuery = new SolrQuery();
        solrQuery.set("q","s_name:花");
        QueryResponse response = solrClient.query(solrQuery);
        //获取对象
        List<Solr> beans = response.getBeans(Solr.class);
        //Solr solr = beans.get(0);
        return null;
    }
    //不使用实体返回solr查询结果
    public List<SolrDto> queryNoBeans() throws IOException, SolrServerException {
        List<SolrDto> solrList = new LinkedList<SolrDto>();
        SolrQuery solrQuery = new SolrQuery();
        //查询条件
        solrQuery.set("q","s_name:花");

        //过滤条件
        //solrQuery.set("fq", "s_price:[30 TO 50]");

        //排序
        solrQuery.addSort("s_orderBy", SolrQuery.ORDER.asc);

        //分页
        solrQuery.setStart(0);
        solrQuery.setRows(5);

        //默认域
        // params.set("df", "s_title");

        //只查询指定域
        //solrQuery.set("fl", "id,s_name,s_price");

        //高亮
        //打开开关
        solrQuery.setHighlight(true);
        //指定高亮域
        solrQuery.addHighlightField("s_name");
        //设置前缀
        solrQuery.setHighlightSimplePre("<span style='color:red'>");
        //设置后缀
        solrQuery.setHighlightSimplePost("</span>");
        System.out.println(solrQuery.toString());
        QueryResponse response = solrClient.query(solrQuery);
        SolrDocumentList results = response.getResults();
        long numFound = results.getNumFound();

        //获取高亮显示的结果, 高亮显示的结果和查询结果是分开放的
        Map<String, Map<String, List<String>>> highlight = response.getHighlighting();

        for (SolrDocument result : results) {
            SolrDto solrDto = new SolrDto();
            String id = (String) result.get("id");
            solrDto.setId(Integer.parseInt(id));
            solrDto.setPrice((Double) result.get("s_price"));

            Map<String, List<String>> map = highlight.get(result.get("id"));
            List<String> list = map.get("s_name");
            solrDto.setName(list.get(0));
            solrList.add(solrDto);
        }
        return solrList;
    }

    @Override
    public void save() throws Exception {
        Solr solr = solrMapper.selectByPrimaryKey(2);
        //solr8小时时差
        Date updatedtime = solr.getUpdatedtime();
        updatedtime.setTime(updatedtime.getTime()+28800000L);
        solr.setUpdatedtime(updatedtime);
        solrClient.addBean(solr);
        solrClient.commit();
    }

    public void delete(String id) throws Exception {
        solrClient.deleteById(id);
        solrClient.commit();    
}

3.使用solrj对象 id为字符串 对应field

@SolrDocument(solrCoreName = "ciri_core")
public class Solr implements Serializable {
    @Field("id")
    private String id;
    @Field("s_name")
    private String name;
    @Field("s_title")
    private String title;
    private Integer category;
    @Field("s_content")
    private String content;
    @Field("s_price")
    private Double price;
    @Field("s_color")
    private String color;
    @Field("s_orderBy")
    private Integer orderby;
    @Field("s_updatetime")
    private Date updatedtime;
get/set方法
}
