- 总结
注：在此之前需要下载elasticsearch以及拼音分词器。可以查看这篇文章，免费下载，下载完直接解压就行。https://download.csdn.net/download/weixin_47874230/86514890
一、引入pom依赖
spring-data-elasticsearch版本需要与springboot版本对应，此处使用springboot版本为2.2.13.RELEASE
<dependency><groupId>org.springframework.data</groupId><artifactId>spring-data-elasticsearch</artifactId><version>3.2.12.RELEASE</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency>
二、修改yml文件
server:port: 8080
spring:elasticsearch:rest:uris:- http://localhost:9200三、创建实体类GoodsDoc.java
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.*;
import org.springframework.data.elasticsearch.core.completion.Completion;
import java.util.Date;@Data
@AllArgsConstructor
@NoArgsConstructor
@Document(indexName = "goods", shards = 1, replicas = 0) //type = "_doc" ,
public class GoodsDoc {@Id@Field(type = FieldType.Keyword)private String id;@CompletionField(analyzer = "ik_smart", searchAnalyzer = "ik_smart", maxInputLength = 100)private Completion title;@Field(type = FieldType.Text) //测试用，当name和title值相同时，检索结果区别,title查出结果数据较少，name为正常查询private String name;@Field(type = FieldType.Float)private float price;@Field(type = FieldType.Text)private String desc;@Field(type = FieldType.Date, format = DateFormat.custom, pattern = "yyyy-MM-dd HH:mm:ss")@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")private Date createdTime;@Field(type = FieldType.Date, format = DateFormat.custom, pattern = "yyyy-MM-dd HH:mm:ss")@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")private Date modifiedTime;
}
四、创建GoodsMapper.java
import com.example.elasticsearch7demo.entity.GoodsDoc;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import org.springframework.stereotype.Repository;@Repository
public interface GoodsMapper extends ElasticsearchRepository<GoodsDoc, String> {}五、创建GoodsController.java
包含创建索引，添加数据，测试功能
import com.example.elasticsearch7demo.mapper.GoodsMapper;
import org.elasticsearch.action.search.SearchResponse;
import org.elasticsearch.search.suggest.Suggest;
import org.elasticsearch.search.suggest.SuggestBuilder;
import org.elasticsearch.search.suggest.SuggestBuilders;
import org.elasticsearch.search.suggest.completion.CompletionSuggestionBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.data.elasticsearch.core.completion.Completion;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.stream.Collectors;@RestController
@RequestMapping
public class GoodsController {@Autowiredprivate ElasticsearchRestTemplate restTemplate;@Autowiredprivate GoodsMapper goodsMapper;//创建索引和映射@GetMapping("/create")public void testCreateIndex(){restTemplate.createIndex(GoodsDoc.class);restTemplate.putMapping(GoodsDoc.class);}//添加数据@GetMapping("/insert")public void addData() throws Exception {List<GoodsDoc> orderDocs = new ArrayList<>();List<String> suggestList = new ArrayList<>();String title = "笔记本电脑";suggestList.add(title); //可以把多个内容作为suggest的数据源Completion suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));GoodsDoc orderDoc = new GoodsDoc("1", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "笔记本";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("2", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "笔记本支架";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("3", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "笔记本内存条";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("4", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "联想笔记本";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("5", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "华硕笔记本";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("6", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "联想台式机";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("7", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "笔记本电脑是联想牌子的";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("8", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);suggestList = new ArrayList<>();title = "你喜欢什么牌子的笔记本？";suggestList.add(title);suggest = new Completion(suggestList.toArray(new String[suggestList.size()]));orderDoc = new GoodsDoc("9", suggest,title, 100,"笔记本电脑非常方便",new Date(),new Date());orderDocs.add(orderDoc);goodsMapper.saveAll(orderDocs);}//测试@GetMapping("/test")public List<String> search(@RequestParam("keywords") String keywords){// 使用suggest进行标题联想CompletionSuggestionBuilder suggest = SuggestBuilders.completionSuggestion("title")//根据什么前缀来联想
// .prefix("笔记本").prefix(keywords)// 跳过重复过滤.skipDuplicates(true)// 匹配数量.size(10);SuggestBuilder suggestBuilder = new SuggestBuilder();suggestBuilder.addSuggestion("title-suggest",suggest);//执行查询SearchResponse suggestResp = restTemplate.suggest(suggestBuilder, GoodsDoc.class);//拿到Suggest结果Suggest.Suggestion<? extends Suggest.Suggestion.Entry<? extends Suggest.Suggestion.Entry.Option>> orderSuggest = suggestResp.getSuggest().getSuggestion("title-suggest");// 处理返回结果List<String> suggests = orderSuggest.getEntries().stream().map(x -> x.getOptions().stream().map(y->y.getText().toString()).collect(Collectors.toList())).findFirst().get();// 输出内容for (String str : suggests) {System.out.println("自动补全 = " + str);}return suggests;}}六、结果
总结
