• springboot整合elasticsearch

    1、创建一个springboot工程并加入相关依赖

    pom.xml文件

    1. "1.0" encoding="UTF-8"?>
    2. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    2、创建一个配置类，获取ES工具类对象

    1. @Configuration
    2. public class EsConfig {
    3.     @Bean
    4.     public RestHighLevelClient restHighLevelClient(){
    5.         RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
    6.                 RestClient.builder(new HttpHost("127.0.0.1",9200,"http"))
    7.         );
    8.         return restHighLevelClient;
    9.     }
    10. }

    3、进行相关的ES操作

    3.1 对索引的相关操作

    3.1.1 创建索引

    1. @SpringBootTest
    2. class SpringbootEsApplicationTests {
    3.  
    4.     @Autowired
    5.     private RestHighLevelClient client;
    6.  
    7.     /**
    8.      * 添加索引
    9.      * @throws Exception
    10.      */
    11.     @Test
    12.     public void testCreateIndex() throws Exception{
    13.         CreateIndexRequest createIndexRequest = new CreateIndexRequest("springboot-es01");
    14.         CreateIndexResponse createIndexResponse = client.indices().create(createIndexRequest, RequestOptions.DEFAULT);
    15.         System.out.println(createIndexResponse.isAcknowledged());
    16.     }
    17. }

    3.1.2 删除索引

    1. @SpringBootTest
    2. class SpringbootEsApplicationTests {
    3.  
    4.     @Autowired
    5.     private RestHighLevelClient client;
    6.  
    7.     /**
    8.      * 删除索引
    9.      * @throws Exception
    10.      */
    11.     @Test
    12.     public void testDeleteIndex() throws Exception{
    13.         DeleteIndexRequest deleteIndexRequest = new DeleteIndexRequest("springboot-es01");
    14.         AcknowledgedResponse delete = client.indices().delete(deleteIndexRequest, RequestOptions.DEFAULT);
    15.         System.out.println(delete.isAcknowledged());
    16.     }
    17. }

    9.      * @throws Exception
    10.      */
    11.     @Test
    12.     public void testIndexExits() throws Exception{
    13.         GetIndexRequest getIndexRequest = new GetIndexRequest("springboot-es01");
    14.         boolean exists = client.indices().exists(getIndexRequest, RequestOptions.DEFAULT);

    7.         IndexRequest indexRequest = new IndexRequest("springboot-es01");
    8.         //指定文档的id
    9.         indexRequest.id("1");
    10.         //指定文档的内容，XContentType xContentType 什么格式
    11.         indexRequest.source(JSON.toJSONString(new User("dumpling",21,"新加坡")),XContentType.JSON);
    12.         IndexResponse index = client.index(indexRequest, RequestOptions.DEFAULT);

    31.         Arrays.stream(hits).forEach(item-> System.out.println(item.getHighlightFields()));
    32.     }

    4、京东搜索案例

    4.1 创建项目

    pom.xml

    1. <dependencies>
    3. <dependency>
    4.     <groupId>org.jsoupgroupId>
    5.     <artifactId>jsoupartifactId>
    6.     <version>1.15.2version>
    7. dependency>
    8. <dependency>
    9.     <groupId>com.alibabagroupId>
    10.     <artifactId>fastjsonartifactId>
    11.     <version>2.0.10version>
    12. dependency>
    13. <dependency>
    14.     <groupId>org.springframework.bootgroupId>
    15.     <artifactId>spring-boot-starter-data-elasticsearchartifactId>
    16. dependency>
    17. <dependency>
    18.     <groupId>org.springframework.bootgroupId>
    19.     <artifactId>spring-boot-starter-webartifactId>
    20. dependency>

    4.2 爬取京东商品工具类

    1. public class HtmlParseUtil {
    2.     public static List ParseJd(String keyword) throws Exception {
    3.         String path = "https://search.jd.com/Search?keyword="+keyword;
    4.         //获取京东搜索的整个网页对象
    5.         Document document = Jsoup.parse(new URL(path), 30000);
    6.         //System.out.println(document);
    7.         Element j_goodsList = document.getElementById("J_goodsList");
    8.         //System.out.println(j_goodsList);
    9.         Elements li = j_goodsList.getElementsByTag("li");
    10.         //System.out.println(li);
    11.         List list = new ArrayList<>();
    12.         for (Element e : li){
    13.             String pPrice = e.getElementsByClass("p-price").text();
    14.             String pName = e.getElementsByClass("p-name").text();
    15.             String pImg = e.getElementsByTag("img").attr("data-lazy-img");
    16.             //System.out.println(pImg);
    17.             list.add(new Product(pName,pImg,pPrice));
    18.         }
    19.         //System.out.println(list);
    20.         return list;
    21.     }
    22. }

    4.3 ES配置类

    如果不写这个配置类的话，默认连接的是本地的elasticsearch

    1. @Configuration
    2. public class EsConfig {
    3.     @Bean
    4.     public RestHighLevelClient restHighLevelClient(){
    5.         RestHighLevelClient restHighLevelClient = new RestHighLevelClient(
    6.                 RestClient.builder(new HttpHost("127.0.0.1",9200,"http"))
    7.         );
    8.         return restHighLevelClient;
    9.     }
    10. }

    9.     @GetMapping("export/{keyword}")
    10.     public CommonResult export(@PathVariable String keyword) throws Exception {
    11.         return productService.export(keyword);
    12.     }
    13. }

    4.4.2 service层

    4.     private RestHighLevelClient client;
    5.  
    6.     public CommonResult export(String keyword) throws Exception{
    7.         List products = HtmlParseUtil.ParseJd(keyword);
    8.         //1、创建索引
    9.         GetIndexRequest getIndexRequest = new GetIndexRequest("jd_product");
    10.         boolean exists = client.indices().exists(getIndexRequest,RequestOptions.DEFAULT);
    11.         if (!exists){
    12.             CreateIndexRequest createIndexRequest = new CreateIndexRequest("jd_product");
    13.             CreateIndexResponse createIndexResponse = client.indices().create(createIndexRequest, RequestOptions.DEFAULT);
    14.             System.out.println("是否创建索引："+createIndexResponse.isAcknowledged());
    15.         }
    16.         BulkRequest bulkRequest = new BulkRequest("jd_product");
    17.         products.stream().forEach(item-> bulkRequest.add(new IndexRequest().source(JSON.toJSONString(item), XContentType.JSON)));
    18.         BulkResponse bulk = client.bulk(bulkRequest, RequestOptions.DEFAULT);
    19.         System.out.println(bulk.hasFailures());
    20.         if (!bulk.hasFailures()){
    21.             return new CommonResult(2000,"添加成功",null);
    22.         }
    23.         return new CommonResult(5000,"添加失败",null);
    24.     }
    25. }

    8.         SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    9.         MatchQueryBuilder matchQueryBuilder = QueryBuilders.matchQuery("name",keyword);
    10.         searchSourceBuilder.query(matchQueryBuilder);
    11.         //设置分页
