springboot2整合spring-data-elasticsearch

一、简介

二、安装elasticsearch

安装传送门

三、springboot2整合spring-data-elasticsearch

1、版本

spring-boot 2.1.3.RELEASE
elasticsearch 6.5.0
spring-data-elasticsearch 3.1.5.RELEASE

2、引入坐标

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

3、增加配置

spring:
  data:
    elasticsearch:
      cluster-name: docker-cluster
      cluster-nodes: 127.0.0.1:9200
      repositories:
        enabled: true

cluster-name 可以访问 http://{ip}:{port} 获取

eg： http://localhost:9200/

完成以上三步，基础工作已经做完了

四、使用spring-data-elasticsearch

1.定义数据模型

比如我这边是以商品为模型

@Data
@Document(indexName = "product",type = "product",shards = 3,replicas = 1)
public class ESProduct implements Serializable{

    @ESId
    @Id
    private String id;
    private String title;
    //private String desc;
    private String sellPoint;
    private Double price;
    private Integer num;
    private String barcode;
    private String image;
    private String cid;
    private String cname;
    private Integer status;
    private Date created;
    private Date updated;

}

2. 建立索引，定义type类型，并定义个字段类型

PUT /product


PUT /product
{
  "settings": {
    "number_of_shards": 3,
    "number_of_replicas": 1
  },
  "mappings": {
    "product": {
			"properties": {
				"updated": {
					"type": "date",
					"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
				},
				"created": {
					"type": "date",
					"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
				},
				"status": {
					"type": "integer"
				},
				"cname": {
					"type": "text"
				},
				"cid": {
					"type": "text"
				},
				"image": {
					"type": "keyword"
				},
				"num": {
					"type": "integer"
				},
				"price": {
					"type": "double"
				},
				"sellPoint": {
					"type": "text"
				},
				"title": {
					"type": "text"
				},
				"id": {
					"type": "keyword"
				}
			}
		}
  }
}

3. 导入数据。

这里留个坑位，以后补

4. 使用

（1）创建es dao

直接继承ElasticsearchRepository这个类，基本的CRUD方法都有了，直接使用

@Repository
public interface ProductRepository extends ElasticsearchRepository<ESProduct,String> {

}

（2）创建es manager

定义接口


public interface ESProductManager {

    //批量增加数据
    void addDocuments(List<ESProduct> products);

    //根据ID查询数据
    ESProduct getProductById(String id);

    //根据产品类别名称分页搜索
    Page<ESProduct> findByCName(String cname, Integer page,Integer count);

    //根据产品类别Id分页搜索
    Page<ESProduct> findByCId(String cname, Pageable pageable);

    //根据时间段检索产品,并且对 sellPoint字段 查询
    Page<ESProduct> getProductByCreateTime(Date startTime, Date endTime,String sellPoint, Pageable pageable,Sort sort);

}

实现


@Service
@Slf4j
public class ESProductManagerImpl implements ESProductManager {

    @Autowired
    ProductRepository productRepository;
    @Autowired
    private ElasticsearchTemplate elasticsearchTemplate;

    @Override
    public void addDocuments(List<ESProduct> products) {
        if (CollectionUtils.isEmpty(products)){
            return;
        }
        List<ESProduct> collect = products.stream().filter(Objects::nonNull).collect(Collectors.toList());
        productRepository.saveAll(collect);
    }

    @Override
    public ESProduct getProductById(String id) {
        Optional<ESProduct> byId = productRepository.findById(id);
        return byId.isPresent()? byId.get() : null;
    }

    @Override
    public Page<ESProduct> findByCName(String cname, Integer page,Integer count) {
        SearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withQuery(matchPhraseQuery("cname",cname))
                .withIndices("product")
                .withTypes("product")
                .withPageable(PageRequest.of(page,count))
                .withSort(new FieldSortBuilder("updated").order(SortOrder.DESC))
                .build();
        return productRepository.search(searchQuery);
    }

    @Override
    public Page<ESProduct> findByCId(String cid, Pageable pageable) {
        //BoolQueryBuilder queryBuilder = new BoolQueryBuilder();
        //queryBuilder.must(QueryBuilders.matchQuery("cid", cid));
        SearchQuery searchQuery = new NativeSearchQueryBuilder()
                .withQuery(QueryBuilders.termQuery("cid",cid))
                .withIndices("product")
                .withTypes("product")
                .withPageable(pageable)
                .build();
        return productRepository.search(searchQuery);
    }

    @Override
    public Page<ESProduct> getProductByCreateTime(Date startTime, Date endTime,String sellPoint, Pageable pageable, Sort sort) {

        CriteriaQuery criteriaQuery = new CriteriaQuery(new Criteria()
                .and(new Criteria("updated").greaterThanEqual(
                        startTime.getTime()).lessThanEqual(endTime.getTime()))
                .and(new Criteria("sellPoint").contains("北京")))
                .setPageable(pageable)
                .addSort(sort);
        return elasticsearchTemplate.queryForPage(criteriaQuery,ESProduct.class);
    }
}

ElasticsearchTemplate 这个模板类，也有很多有用的API。

（3）Test controller

@RestController
@RequestMapping("/es/product")
public class ESProductController {


    @Autowired
    ItemService itemService;
    @Autowired
    ESProductManager esProductManager;

    @RequestMapping("/syncData")
    public Object syncData(){
        itemService.syncData();
        return "1223";
    }


    @RequestMapping("/search")
    @ResponseBody
    public Object getById() throws Exception {
        Map<String,Object> res = Maps.newHashMap();
        //根据Id查询
        ESProduct productById = esProductManager.getProductById("536563");
        res.put("getProductById",productById);

        //根据产品类别名称分页搜索
        Page<ESProduct> findByCName = esProductManager.findByCName("手机", 1, 5);
        res.put("findByCName",findByCName);
        //根据产品类别Id分页搜索
        Page<ESProduct> findByCId = esProductManager.findByCId("560", PageRequest.of(1,5));
        res.put("findByCId",findByCId);

        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        //根据时间段检索产品,并且对 sellPoint字段 查询
         Page<ESProduct> getProductByCreateTime = esProductManager.getProductByCreateTime(dateFormat.parse("2015-03-08 21:33:18"), new Date(),"北京", PageRequest.of(2,5) ,Sort.by("updated").descending());
        res.put("getProductByCreateTime",getProductByCreateTime);
        return res;
    }
