.product{height:333px}</style>

6.后端代码

6.1.运行es和kibana

6.2.写一个工具类--用于获取京东的数据

public class HtmlParseUtil {public List<Product> parseJd (String keyword)throws Exception{String path="https://search.jd.com/Search?keyword="+keyword;//Document整个网页对象Document parse = Jsoup.parse(new URL(path), 30000);//获取商品Element j_goodsList = parse.getElementById("J_goodsList");//获取每一个商品Elements li = j_goodsList.getElementsByTag("li");List<Product> list=new ArrayList<>();//循环for (Element element:li) {//获取下边为0的价格String p_price = element.getElementsByClass("p-price").eq(0).text();//获取商品的名字String p_name = element.getElementsByClass("p-name").eq(0).text();//System.out.println(p_name+""+p_price);//获取商品的图片  attr--属性String img = element.getElementsByTag("img").eq(0).attr("data-lazy-img");list.add(new Product(p_name,p_price,img));}return list;}
}

6.3.创建返回共同数据工具类

@Data
@AllArgsConstructor
@NoArgsConstructor
public class CommentResult {private int code;private String msg;private Object data;
}

6.4.将获取到京东的数据,添加到es中

6.4.1.controller层

@RestController
@RequestMapping("/product")
public class ProductController {@Autowiredprivate ProductService productService;//将京东的数据导入到es中@GetMapping("/export/{keyword}")public CommentResult product(@PathVariable String keyword) throws Exception {return  productService.export(keyword);}
}

6.4.2.service层

package com.guan.service;import com.alibaba.fastjson.JSON;
import com.guan.entity.Product;
import com.guan.util.CommentResult;
import com.guan.util.HtmlParseUtil;
import org.elasticsearch.action.bulk.BulkRequest;
import org.elasticsearch.action.bulk.BulkResponse;
import org.elasticsearch.action.index.IndexRequest;
import org.elasticsearch.client.RequestOptions;
import org.elasticsearch.client.RestHighLevelClient;
import org.elasticsearch.client.indices.CreateIndexRequest;
import org.elasticsearch.client.indices.GetIndexRequest;
import org.elasticsearch.common.xcontent.XContentType;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.servlet.HandlerInterceptor;import java.util.List;/*** TODO** @author lenovo* @version 1.0* @since 2022-08-17  11:42:53*/
@Service
public class ProductService {@Autowired//用来操作文档的private RestHighLevelClient client;//将京东的数据导入到es中public CommentResult export(String keyword) throws Exception{//调用工具类List<Product> list = HtmlParseUtil.parseJd(keyword);//数据量大,使用批量添加 bulk//先判断一下索引存在不存在GetIndexRequest getIndexRequest=new GetIndexRequest("jd");boolean exists = client.indices().exists(getIndexRequest, RequestOptions.DEFAULT);System.out.println(exists);//如果没有索引，创建一个索引if (!exists){CreateIndexRequest createIndexRequest=new CreateIndexRequest("jd");client.indices().create(createIndexRequest,RequestOptions.DEFAULT);}//有索引就批量添加文档//创建一个bulkRequest对象BulkRequest bulkRequest=new BulkRequest("jd");//添加数据for (Product product:list) {IndexRequest indexRequest=new IndexRequest();indexRequest.source(JSON.toJSONString(product), XContentType.JSON);bulkRequest.add(indexRequest);}BulkResponse bulk = client.bulk(bulkRequest, RequestOptions.DEFAULT);//判断是否报错  报错返回的true 不报错返回的是falseif (bulk.hasFailures()) {return new CommentResult(5000,"添加失败",null);}return new CommentResult(2000,"添加成功",null);}
}

6.4.3.访问

注意不要写中文会乱码

6.4.4.测试一下

6.5.查询数据从es中

6.5.1.controller

 //查询数据从es中@GetMapping("/search/{keywaord}")public CommentResult search(@PathVariable String keyword)throws Exception{return productService.search(keyword);}

6.5.2.service

 //根据关键字搜索public CommentResult search(String keyword) throws Exception{//创建一个搜索请求对象SearchRequest searchRequest=new SearchRequest("jd");//创建一个条件对象SearchSourceBuilder searchSourceBuilder=new SearchSourceBuilder();//查询构造器TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery("title", keyword);searchSourceBuilder.query(termQueryBuilder);//将条件对象放入到搜索请求对象中searchRequest.source(searchSourceBuilder);SearchResponse search = client.search(searchRequest, RequestOptions.DEFAULT);//将结果封装到hits中SearchHits hits = search.getHits();//获取总条数long value = hits.getTotalHits().value;//返回的是commentResult对象,但是在es中查询的时候是map类型List<Map<String,Object>> list=new ArrayList<>();SearchHit[] hits1 = hits.getHits();for (SearchHit searchHit:hits1) {//循环的时候拿到mapMap<String, Object> map = searchHit.getSourceAsMap();list.add(map);}return new CommentResult(2000,"查询成功",list);}

6.5.3.访问

7.用前端访问

7.1.报错

7.2.解决问题

在controller层添加@CrossOrigin注解

8.添加高亮

 //根据关键字搜索public CommentResult search(String keyword) throws Exception{//创建一个搜索请求对象SearchRequest searchRequest=new SearchRequest("jd");//创建一个条件对象SearchSourceBuilder searchSourceBuilder=new SearchSourceBuilder();//查询构造器TermQueryBuilder termQueryBuilder = QueryBuilders.termQuery("title", keyword);searchSourceBuilder.query(termQueryBuilder);//设置高亮HighlightBuilder highlightBuilder=new HighlightBuilder();//设置那个列高亮highlightBuilder.field("title");//设置高亮的前置标签highlightBuilder.preTags("<font color='red'>");//设置高亮的后置标签highlightBuilder.postTags("</font>");//将高亮给条件对象searchSourceBuilder.highlighter(highlightBuilder);//将条件对象放入到搜索请求对象中searchRequest.source(searchSourceBuilder);SearchResponse search = client.search(searchRequest, RequestOptions.DEFAULT);//将结果封装到hits中SearchHits hits = search.getHits();//获取总条数long value = hits.getTotalHits().value;//返回的是commentResult对象,但是在es中查询的时候是map类型List<Map<String,Object>> list=new ArrayList<>();SearchHit[] hits1 = hits.getHits();for (SearchHit searchHit:hits1) {//循环的时候拿到mapMap<String, Object> map = searchHit.getSourceAsMap();//获取高亮的字段Map<String, HighlightField> highlightFields = searchHit.getHighlightFields();//获取文本HighlightField title = highlightFields.get("title");Text[] fragments = title.getFragments();StringBuffer sb=new StringBuffer();for (Text text:fragments) {sb.append(text);}map.put("title",sb);list.add(map);}return new CommentResult(2000,"查询成功",list);}

9.添加分页

es默认每页显示10条

9.1.前端

<!--分页@size-change:页面显示条数改变是触发的事件@current-change:页码改变时触发的事件current-page:当期的页面page-sizes:接受一个整形的数组，数组元素为显示的选择每页显示的个数page-size:每页显示的页数total:总条数--><el-pagination@size-change="handleSizeChange"@current-change="handleCurrentChange":current-page="currentPage":page-sizes="pageSizes":page-size="pageSize":total="total"layout="total, sizes, prev, pager, next, jumper"></el-pagination>

<script>export default {name: "jd",data(){return {//当前显示页面变量currentPage: 1,//接受一个整形的数组，数组元素为显示的选择每页显示的个数pageSizes: [5, 10, 15, 20],//每页显示的页数pageSize: 5,//总条数total: 0,keyword: '', // 搜索的关键字results:[] // 后端返回的结果}},methods:{handleSizeChange(val) {//每页显示的条数大小改变时触发的方法this.pageSize = val;this.searchKey();},//页码改变时触发的方法handleCurrentChange(val) {this.currentPage = val;this.searchKey();},searchKey(){this.axios.get('/product/search/'+this.keyword+"/"+this.currentPage+"/"+this.pageSize).then(response=>{console.log(response.data)this.total=response.data.data[0].total;this.results=response.data.data;})}}}

9.2.后端

9.2.1.controller层

  //查询数据从es中@GetMapping("/search/{keyword}/{currentPage}/{pageSize}")public CommentResult search(@PathVariable String keyword,@PathVariable Integer currentPage,@PathVariable Integer pageSize)throws Exception{return productService.search(keyword,currentPage,pageSize);}

9.2.2.service

10.添加分词

10.1.添加分词前先把自己的写的京东的索引给删除

不删除的话,重启es的时候,es会打不开

10.2.在添加索引的时候设置分词

PUT /jd
{"mappings":{"properties": {"title":{"type": "text","analyzer": "ik_max_word"},"price":{"type": "keyword"},"imgUrl":{"type": "keyword"}}}}

注意：title里面的数据跟数据库的数据是一样的

10.3.将我们下载的分词放入到plugis中

10.4.重启es

10.5.运行项目,添加数据
