整合Elasticsearch实现商品搜索
Elasticsearch实现商品搜索总结：
1.在pom.xml中添加相关依赖，修改springboot配置，
2.添加对应商品文档对象EsProduct，注意需要中文分词的注解
3.添加EsProductRepository接口用于操作Elasticsearch，继承ElasticsearchRepository接口，这样就拥有了一些基本的Elasticsearch数据操作方法（一些搜索方法等等，curd），同时可以定义一个衍生查询方法。
(阅读代码后发现，es基本数据操作方法基于JPA,继承PagingAndSortingRepository<T, ID> 继承 CrudRepository（JPA）)
4.添加EsProductService接口，实现类从数据库中导入所有商品到ES,删除/创建/商品，
根据关键字搜索名称或者副标题，
根据关键字搜索名称或者副标题复合查询，
根据商品id推荐相关商品，
获取搜索词相关品牌、分类、属性
整合Elasticsearch实现商品搜索
在pom.xml中添加相关依赖
<!--Elasticsearch相关依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-elasticsearch<artifactId>
</dependency>Copy to clipboardErrorCopied
修改SpringBoot配置文件
修改application.yml文件，在spring节点下添加Elasticsearch相关配置。
data:
elasticsearch:
repositories:
enabled: true
cluster-nodes: 127.0.0.1:9300 # es的连接地址及端口号
cluster-name: elasticsearch # es集群的名称Copy to clipboardErrorCopied
添加商品文档对象EsProduct
不需要中文分词的字段设置成@Field(type = FieldType.Keyword)类型，需要中文分词的设置成@Field(analyzer = "ik_max_word",type = FieldType.Text)类型。

添加EsProductRepository接口用于操作Elasticsearch
继承ElasticsearchRepository接口，这样就拥有了一些基本的Elasticsearch数据操作方法，同时定义了一个衍生查询方法。
package com.macro.mall.tiny.nosql.elasticsearch.repository;
import com.macro.mall.tiny.nosql.elasticsearch.document.EsProduct;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
/**
* 商品ES操作类
* Created by macro on 2018/6/19.
*/
public interface EsProductRepository extends ElasticsearchRepository<EsProduct, Long> {
/**
* 搜索查询
*
* @param name 商品名称
* @param subTitle 商品标题
* @param keywords 商品关键字
* @param page 分页信息
* @return
*/
Page<EsProduct> findByNameOrSubTitleOrKeywords(String name, String subTitle, String keywords, Pageable page);
}

添加EsProductService接口
package com.macro.mall.tiny.service;
import com.macro.mall.tiny.nosql.elasticsearch.document.EsProduct;
import org.springframework.data.domain.Page;
import java.util.List;
/**
* 商品搜索管理Service

public interface EsProductService {
/**

*/
int importAll();
/**
* 根据id删除商品
*/
void delete(Long id);
/**
* 根据id创建商品
*/
EsProduct create(Long id);
/**

*/
void delete(List<Long> ids);
/**

Page<EsProduct> search(String keyword, Integer pageNum, Integer pageSize);
