pom.xml中配置使用的依赖

        <spring-boot.version>2.3.4.RELEASE</spring-boot.version>
        <spring-cloud.version>Hoxton.RELEASE</spring-cloud.version>

elasticsearch依赖

  <!-- 使用ElasticsearchRestTemplate模板依赖-->
         <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-elasticsearch</artifactId>
        </dependency>
      

在application.xml中配置文件

#项目名

  application:
    name: jq-search
    #连接es
  elasticsearch:
    rest:
      uris: http://192.168.230.134:9200

创建controller类进行简单测试

package com.jq.controller;

import com.jq.model.SerchModel;
import org.elasticsearch.index.query.QueryBuilders;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.domain.PageRequest;
import org.springframework.data.domain.Pageable;
import org.springframework.data.elasticsearch.core.ElasticsearchRestTemplate;
import org.springframework.data.elasticsearch.core.ElasticsearchTemplate;
import org.springframework.data.elasticsearch.core.SearchHit;
import org.springframework.data.elasticsearch.core.SearchHits;
import org.springframework.data.elasticsearch.core.aggregation.AggregatedPage;
import org.springframework.data.elasticsearch.core.query.NativeSearchQuery;
import org.springframework.data.elasticsearch.core.query.NativeSearchQueryBuilder;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;
import java.util.stream.Stream;

@RestController
@CrossOrigin
@RequestMapping("search")
public class SearchController {

    @Autowired
    private ElasticsearchRestTemplate elasticsearchRestTemplate;

    @GetMapping()
    public Object getSerch(String name){
        //构建分页
        Pageable pageable= PageRequest.of(0,999);
        NativeSearchQueryBuilder builder=new NativeSearchQueryBuilder();
        NativeSearchQuery query=builder.withQuery(QueryBuilders.queryStringQuery(name))
                .withPageable(pageable)
                .build();
        SearchHits<SerchModel> search = elasticsearchRestTemplate.search(query, SerchModel.class);
        Stream<SearchHit<SerchModel>> searchHitStream = search.get();
        return searchHitStream;
    }

}
