Spring Data for Apache Solr

添加依赖

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

编写实体类(省略了getset)

@SolrDocument(collection = "testcore")
public class Menu {
    @Id
    @Field("id")
    private Long menu_id;

    @Field("myfield")
    private String menu_name;
}

编写springboot入口类并启动

@SpringBootApplication
public class SpringDataSolrApp {
    public static void main(String[] args) {
        SpringApplication.run(SpringDataSolrApp.class,args);
   }
}

编写测试方法

@SpringBootTest(classes = SpringDataSolrApp.class)
@RunWith(SpringRunner.class)
public class TestSpringdataSolr {

    @Autowired
    private SolrTemplate solrTemplate;

    private String coreName = "testcore";

    @Test
    public void testUpdate() {
        SolrInputDocument document = new SolrInputDocument();

        document.addField("id", 10010);
        document.addField("myfield", "中国联通");

        UpdateResponse updateResponse = solrTemplate.saveDocument(coreName, document);

        System.out.println(updateResponse.getStatus() == 0 ? "保存成功" : "保存失败");

        solrTemplate.commit(coreName);
    }

    @Test
    public void testDelete(){
        //根据id 删除
        UpdateResponse updateResponse = solrTemplate.deleteByIds(coreName, "2000");
        System.out.println(updateResponse.getStatus() == 0 ? "删除成功" : "删除失败");

        // 根据条件删除
        Query query = new SimpleQuery();
        query.addCriteria(Criteria.where("myfield").is("系统"));
        UpdateResponse updateResponse1 = solrTemplate.delete(coreName, query);
        System.out.println(updateResponse1.getStatus() == 0 ? "删除成功" : "删除失败");

        solrTemplate.commit(coreName);
    }

    @Test
    public void query(){

        // 分页条件
        Query query = new SimpleQuery();
        query.addCriteria(Criteria.where("myfield").is("管理"));
        // 从哪条开始查询 & 每页数据条数
        query.setOffset(0L);
        query.setRows(3);
        // 降序
        query.addSort(Sort.by(Sort.Direction.DESC,"id"));

        Page<Menu> pages = solrTemplate.query(coreName, query, Menu.class);
        List<Menu> menus = pages.getContent();

        for (Menu menu : menus) {
            System.out.println(menu);
        }
    }

    @Test
    public void testHighLighting(){

        HighlightQuery query = new SimpleHighlightQuery();

        query.addCriteria(Criteria.where("myfield").is("菜单"));

        HighlightOptions options = new HighlightOptions();
        options.addField("myfield");
        options.setSimplePostfix("<span style='color:red'>");
        options.setSimplePostfix("</span>");

        query.setHighlightOptions(options);

        // 用户存储高亮数据
        List<Menu> result =new ArrayList<>();

        HighlightPage<Menu> menus = solrTemplate.queryForHighlightPage(coreName, query, Menu.class);

        // 获取处理高亮的对象
        List<HighlightEntry<Menu>> highlighted = menus.getHighlighted();
        for (HighlightEntry<Menu> menuHighlightEntry : highlighted) {
            // 没有高亮的数据
            Menu entity = menuHighlightEntry.getEntity();

            // 高亮数据
            List<HighlightEntry.Highlight> highlights = menuHighlightEntry.getHighlights();
            for (HighlightEntry.Highlight highlight : highlights) {
                String hlresult = highlight.getSnipplets().get(0);
                entity.setMenu_name(hlresult);
                System.out.println(entity);
                result.add(entity);
            }
        }
        for (Menu menu : result) {
            System.out.println(menu);
        }

    }
