elasticsearch进阶使用demo

1. dao

   package com.czxy.reporty;
   
   import com.czxy.pojo.TdvdPojo;
   import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
   
   public interface DvdRepostory extends ElasticsearchRepository<TdvdPojo, Integer> {
   }
   

2. service

   package com.czxy.service;
   
   import com.czxy.pojo.TdvdPojo;
   import com.czxy.reporty.DvdRepostory;
   import org.apache.commons.lang3.StringUtils;
   import org.elasticsearch.index.query.*;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.data.domain.Page;
   import org.springframework.data.domain.PageRequest;
   import org.springframework.data.elasticsearch.core.query.NativeSearchQuery;
   import org.springframework.stereotype.Service;
   import org.springframework.transaction.annotation.Transactional;
   
   
   @Service
   @Transactional
   public class Dservice {
       @Autowired
       private DvdRepostory dvdRepostory;
       /**
        * es 根据dvd名字进行查询
        * @param serach
        * @return
        */
       public Page<TdvdPojo> pageQuery(String serach ,Integer page ,Integer size) {
           BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
           if(StringUtils.isNotBlank(serach)){
               WildcardQueryBuilder q1 = QueryBuilders.wildcardQuery("dname","*"+serach+"*");
               QueryBuilder q2 = new QueryStringQueryBuilder(serach).field("dname").defaultOperator(Operator.AND);
               BoolQueryBuilder boolQueryBuilder1 = new BoolQueryBuilder();
   
               boolQueryBuilder1.should(q1).should(q2);
   
               boolQueryBuilder.must(boolQueryBuilder1);
           }
           NativeSearchQuery searchQuery =new NativeSearchQuery(boolQueryBuilder);
   
           searchQuery.setPageable(PageRequest.of(page - 1 ,size ));
           return  this.dvdRepostory.search(searchQuery);
   
       }
   }
   
   

3. controller

   package com.czxy.controller;
   
   import com.czxy.pojo.TdvdPojo;
   import com.czxy.service.Dservice;
   import com.czxy.vo.Result;
   import org.springframework.beans.factory.annotation.Autowired;
   import org.springframework.data.domain.Page;
   import org.springframework.http.HttpStatus;
   import org.springframework.http.ResponseEntity;
   import org.springframework.web.bind.annotation.GetMapping;
   import org.springframework.web.bind.annotation.RequestMapping;
   import org.springframework.web.bind.annotation.RestController;
   
   @RestController
   @RequestMapping("/es")
   public class DvdController {
       @Autowired
       private Dservice dservice;
       @GetMapping("/search")
       public ResponseEntity<Result<TdvdPojo>> search(String search,Integer page, Integer size){
         Page<TdvdPojo> pa= this.dservice.pageQuery(search,page, size);
          Result<TdvdPojo> result = new Result<>(pa.getTotalElements(),pa.getContent());
           System.out.println(result);
          return new ResponseEntity<>(result,HttpStatus.OK);
       }
   
   
   }
   
   

4. pojo

   package com.czxy.pojo;
   
   
   import org.springframework.data.annotation.Id;
   import org.springframework.data.elasticsearch.annotations.Document;
   import org.springframework.data.elasticsearch.annotations.Field;
   import org.springframework.data.elasticsearch.annotations.FieldType;
   
   @Document(indexName="dvdall",type="dvd")
   public class TdvdPojo {
       /**
        * id
        */
       @Id
       private Integer id;
   
       /**
        * dvd名字
        */
      @Field(type = FieldType.Text)
       private String dname;
   
       /**
        * 总的库存量
        */
       @Field(type = FieldType.Long)
       private Integer allnumber;
   
       /**
        * 现在的库存量
        */
       @Field(type = FieldType.Long)
       private Integer nownumber;
   
       /**
        * 借阅的价格
        */
       @Field(type = FieldType.Float)
       private Double brorrowprice;
