微服务电商实战(十二)搭建商品服务搜索引擎
目录
一、简介
二、商品服务数据库
三、es配置索引
四、搭建商品服务
五、前端页面
一、简介
本篇文章要完成的是搭建一个商品服务搜索引擎，使用elasticsearch(下文简称es)作为搜索引擎；
商品数据存放在mysql中，由canal将mysql的商品增量数据同步到es中。
同步方法参考docker安装canal同步mysql8与elasticsearch7数据，canal-adapter中的es7文件夹下的配置文件内容如下
dataSourceKey: defaultDS
destination: product_topic
groupId: g1
esMapping:
_index: products
_id: _id
# upsert: true
# pk: id
sql: "SELECT
p.product_id AS _id,p.product_id AS productId,p.category_id AS categoryId,p.product_name AS productName,
p.subtitle,p.product_specs AS productSpecs,p.product_price AS productPrice,
p.product_stock AS productStock,p.detail,p.master_pic AS masterPic,
p.revision,p.publish_status AS publishStatus,p.audit_status AS auditStatus,
p.created_time AS createdTime,p.updated_time AS updatedTime
FROM
p_product p"
# objFields:
# _labels: array:;
etlCondition: "where p.created_time>={}"
commitBatch: 3000
二、商品服务数据库
首先创建数据库shop-product
在电商项目中，常见的商品表结构，一般会有品牌信息表、供应商信息表、商品分类信息表、商品规格key表、商品规格值表、商品信息表、商品规格表、商品图片信息表、商品评论表等等。这里简单创建一下，本篇文章主要用到的是商品信息表，需要同步数据到es中。
商品信息表
CREATE TABLE `p_product` (
`product_id` INT (11) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT '主键ID',
`category_id` MEDIUMINT UNSIGNED DEFAULT NULL COMMENT '类型ID',
`product_core` VARCHAR (50) NOT NULL COMMENT '商品编码',
`product_name` VARCHAR (128) DEFAULT NULL COMMENT '商品名称',
`master_pic` VARCHAR (255) DEFAULT NULL COMMENT '商品主图url',
`bar_code` VARCHAR (50) NOT NULL COMMENT '国条码',
`brand_id` MEDIUMINT UNSIGNED NOT NULL COMMENT '品牌表的ID',
`supplier_id` MEDIUMINT UNSIGNED NOT NULL COMMENT '商品的供应商ID',
`subtitle` VARCHAR (128) DEFAULT NULL COMMENT '小标题',
`detail` text COMMENT '描述',
`product_specs` text DEFAULT NULL COMMENT '商品规格',
`product_price` DECIMAL (18, 2) DEFAULT NULL COMMENT '商品价格',
`average_cost` DECIMAL (18, 2) NOT NULL COMMENT '商品平均成本',
`product_stock` INT (11) DEFAULT NULL COMMENT '商品库存',
`publish_status` TINYINT NOT NULL DEFAULT 0 COMMENT '上下架状态：0下架,1上架',
`audit_status` TINYINT NOT NULL DEFAULT 0 COMMENT '审核状态：0未审核,1已审核',
`revision` INT (11) UNSIGNED DEFAULT 1 COMMENT '乐观锁',
`created_by` INT (11) UNSIGNED DEFAULT NULL COMMENT '创建人',
`created_time` TIMESTAMP DEFAULT NULL COMMENT '创建时间',
`updated_by` INT (11) UNSIGNED DEFAULT NULL COMMENT '更新人',
`updated_time` TIMESTAMP DEFAULT NULL COMMENT '更新时间',
PRIMARY KEY (`product_id`)
) ENGINE = INNODB AUTO_INCREMENT = 2 DEFAULT CHARSET = utf8 COMMENT = '商品信息表';规格、价格、成本、库存字段是商品的默认规格，这些字段是冗余的，且规格字段存的是中文json数据，好处是方便查询，但是维护会麻烦点，而因为规格key和value是极少会改动的，所以总体来说是利大于弊的。
测试数据insert sql如下：

`updated_time` TIMESTAMP DEFAULT NULL COMMENT '更新时间',
PRIMARY KEY (comment_id)
) ENGINE = INNODB AUTO_INCREMENT = 4 DEFAULT CHARSET = utf8 COMMENT = '商品评论表 ';
三、es配置索引
使用postman添加es索引products
索引结构如下：
{
"mappings":{
"properties": {
"productId":{
"type": "long"
},
"categoryId": {
"type": "long"
},
"productName": {
"type": "text",
"analyzer":"ik_smart",
"search_analyzer":"ik_smart"
},
"subtitle": {
"type": "text",
"analyzer":"ik_smart",
"search_analyzer":"ik_smart"
},
"productSpecs": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"productPrice": {
"type": "double"
},
"productStock":{
"type": "long"
},
"detail": {
"type": "text",
"analyzer":"ik_smart",
"search_analyzer":"ik_smart"
},
"masterPic": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
},
"revision": {
"type": "long"
},
"publishStatus": {
"type": "long"
},
"auditStatus": {
"type": "long"
},
"createdTime": {
"type": "date",
"store": true
},
"updatedTime": {
"type": "date",
"store": true
}
}
}
}
同步数据后使用postman搜索查看
四、搭建商品服务
1、创建跟商品有关的模块
2、创建商品搜索dto输出类
package com.liazhan.product.output.dto;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import java.util.Date;
/**
* @version:V1.0
* @Description:
* @author: Liazhan
* @date 2020/5/24 17:11
*/
@Data
@ApiModel(value = "商品搜索输出实体类")
public class ProductSearchOutDto {
@ApiModelProperty(value = "商品主键ID")
private Integer productId;
@ApiModelProperty(value = "类型ID")
private Integer categoryId;
@ApiModelProperty(value = "商品名称")
private String productName;
@ApiModelProperty(value = "小标题")
private String subtitle;
@ApiModelProperty(value = "商品规格")
private String productSpecs;
@ApiModelProperty(value = "商品价格")
private Double productPrice;
@ApiModelProperty(value = "商品库存")
private Integer productStock;
@ApiModelProperty(value = "商品描述")
private String detail;
@ApiModelProperty(value = "主图")
private String masterPic;
@ApiModelProperty(value = "乐观锁")
private Integer revision;
@ApiModelProperty(value = "上下架状态 0下架 1上架")
private Integer publishStatus;
@ApiModelProperty(value = "审核状态 0未审核 1已审核")
private Integer auditStatus;
@ApiModelProperty(value = "创建时间")
private Date createdTime;
@ApiModelProperty(value = "更新时间")
private Date updatedTime;
}
3、shop-service-api-product模块添加dto依赖和创建商品服务搜索相关接口
pom如下：
shop-service-api
com.liazhan
0.0.1-SNAPSHOT
4.0.0
shop-service-api-product
jar
shop-api-product-dto
com.liazhan
0.0.1-SNAPSHOT
接口如下：
package com.liazhan.product.service;
import com.alibaba.fastjson.JSONObject;
import com.liazhan.base.BaseResponse;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.data.domain.Pageable;
import org.springframework.data.web.PageableDefault;
import org.springframework.web.bind.annotation.GetMapping;
/**
* @version V1.0
* @description:
* @author: Liazhan
* @date: 2020/5/25 22:22
*/
@Api(tags = "商品服务搜索相关接口")
public interface ProductSearchService {
@GetMapping("/search")
@ApiOperation(value = "搜索接口")
@ApiImplicitParams({
@ApiImplicitParam(paramType = "query",name = "keyword",dataType = "String",required = true,value = "搜索关键字"),
@ApiImplicitParam(paramType = "query",name = "page",dataType = "Integer",required = false,value = "第几页,从0开始,默认为0"),
@ApiImplicitParam(paramType = "query",name = "size",dataType = "Integer",required = false,value = "一页几条,默认为10"),
@ApiImplicitParam(paramType = "query",name = "sort",dataType = "String",required = false,value = "排序相关的信息,比如sort=productId&sort=createTime,desc 表示按照主键正序排列基础上按创建时间倒序排列")
})
public BaseResponse search(String keyword, @PageableDefault(page = 0,value = 10) Pageable pageable);
}
4、shop-service-impl-product模块添加依赖，常量类，es实体类，mapper，接口实现类，启动类，配置文件
目录如下：
pom文件如下：
shop-service-impl
com.liazhan
0.0.1-SNAPSHOT
4.0.0
shop-service-impl-product
jar
shop-service-api-product
com.liazhan
0.0.1-SNAPSHOT
org.springframework.boot
spring-boot-starter-data-elasticsearch
ma.glasnost.orika
orika-core
1.5.2
commons-beanutils
commons-beanutils
1.9.3
常量类如下：
package com.liazhan.product.consts;
/**
* @version:V1.0
* @Description: 常量类
* @author: Liazhan
* @date 2020/5/28 15:36
*/
public interface ProductConst {
//商品表商品主键列
String PRODUCT_ID_COLUMN = "productId";
//商品表商品名称列
String PRODUCT_NAME_COLUMN = "productName";
//商品表商品小标题列
String SUBTITLE_COLUMN = "subtitle";
//商品表商品描述列
String DETAIL_COLUMN = "detail";
//商品表商品上架状态列
String PUBLISH_STATUS_COLUMN = "publishStatus";
//商品表商品审核状态列
String AUDIT_STATUS_COLUMN = "auditStatus";
//商品表商品创建时间列
String CREATED_TIME_COLUMN = "createdTime";
//商品已上架状态
Integer PUBLISHED = 1;
//商品已审核状态
Integer AUDITED = 1;
//筛选起始时间
String SCREEN_START_TIME = "2020-05-11 16:00:00";
//筛选结束时间
String SCREEN_END_TIME = "2020-05-18 16:00:00";
//筛选时间格式
String SCREEN_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss";
//es关键词高亮前缀
String HIGHLIGHT_PRETAGS = "";
//es关键词高亮后缀
String HIGHLIGHT_POSTTAGS = "";
//高亮字段显示的最长长度,不配置可能导致高亮不全,文章内容缺失等问题 最大高亮分片数800000
Integer HIGHLIGHT_FRAGMENTSIZE = 800000;
//从第一个分片获取高亮字段
Integer HIGHLIGHT_NUMOFFRAGMENTS = 0;
}
实体类如下：
package com.liazhan.product.es.entity;
import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;
import java.util.Date;
/**
* @version V1.0
* @description: es商品索引
* @author: Liazhan
* @date: 2020/5/25 22:40
*/
@Document(indexName = "products",type = "_doc")
@Data
public class ProductEntity {
//主键id
@Id
private Integer productId;
//类型id
private Integer categoryId;
//商品名称
private String productName;
//小标题
private String subtitle;
//商品规格
private String productSpecs;
//商品价格
private Double productPrice;
//商品库存
private Integer productStock;
//商品详情
private String detail;
//主图
private String masterPic;
//乐观锁
private Integer revision;
//上下架状态 0下架 1上架
private Integer publishStatus;
//审核状态 0未审核 1已审核
private Integer auditStatus;
//创建时间
private Date createdTime;
//更新时间
private Date updatedTime;
}
mapper如下：
package com.liazhan.product.es.mapper;
import com.fasterxml.jackson.core.JsonEncoding;

BoolQueryBuilder boolQuery = QueryBuilders.boolQuery();

启动类如下：
package com.liazhan;
import com.spring4all.swagger.EnableSwagger2Doc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @version V1.0
* @description: 商品服务启动类
* @author: Liazhan
* @date: 2020/5/25 22:33
*/
@SpringBootApplication
@EnableSwagger2Doc
public class AppProduct {
public static void main(String[] args) {
SpringApplication.run(AppProduct.class,args);
}
}
配置文件bootstrap.yml内容如下：
spring:
cloud:
config:
uri: http://localhost:8000 # 配置中心的具体地址，即 config-server
name: product,common # 对应 {application} 部分
profile: dev # 对应 {profile} 部分
label: master # 对应 {label} 部分，即 Git 的分支。如果配置中心使用的是本地存储，则该参数无用
#解决不允许同一个服务中接口中存在多个feign实体bean问题
main:
allow-bean-definition-overriding: true
5、接下来需要在我们的github配置文件仓库中添加商品服务配置文件和修改网关配置文件添加商品服务路由配置
其中prod和test内容都为空，dev内容如下：
server:
port: 8500
spring:
application:
name: liazhan-product
#es配置
data:
elasticsearch:
cluster-name: docker-cluster
cluster-nodes: 47.98.183.103:9300
####swagger相关配置
swagger:
base-package: com.liazhan.product.service
title: 微服务电商项目-商品服务接口
description: 商品服务
version: 1.1
terms-of-service-url: www.baidu.com
contact:

email: [email protected]配置文件github地址https://github.com/liazhan/shop-project-config/tree/daf999ce9d80a03dfc3b2c3ea86cbedacd03f22d
修改网关配置文件product-dev.yml，最终内容如下：
#服务端口号
server:
port: 8300
spring:
application:
name: liazhan-member
datasource:
druid:
# 数据库访问配置, 使用druid数据源
db-type: com.alibaba.druid.pool.DruidDataSource

max-active: 20
# 连接等待超时时间
max-wait: 30000
# 配置检测可以关闭的空闲连接间隔时间

##Jpa配置
jpa:
hibernate:
ddl-auto: update
database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
show-sql: true
#redis配置

port: 6379
pool:
max-idle: 100
min-idle: 1
max-active: 1000
max-wait: -1
####swagger相关配置
swagger:
base-package: com.liazhan.member.service
title: 微服务电商项目-会员服务接口
description: 会员服务
version: 1.1
terms-of-service-url: www.baidu.com
contact:
name: liazhan
email: [email protected]
####会员登陆类型相关配置
login:

value: pc,android,ios
配置文件github地址https://github.com/liazhan/shop-project-config/tree/55d992ff690ee78a83cc7c1173929ee1cd781564
6、修改config配置中心服务application.yml配置文件，添加搜索product路径，内容如下：
server:
port: 8000
eureka:
client:
service-url:
defaultZone: http://localhost:8100/eureka/
spring:
application:
name: config-server
cloud:
config:
server:
git:
uri: https://github.com/liazhan/shop-project-config # 配置git仓库的地址
search-paths: common,eureka,gateway,member,weixin,product # git仓库地址下的相对地址，可以配置多个，用,分割。
bus:
enabled: true
trace:
enabled: true
rabbitmq:
host: 47.98.183.103
port: 5672
username: user
password: password
management:
endpoints:
web:
exposure:
include: "*"
ok，如此便完成了，我们分别启动config、eureka、product服务。
访问http://localhost:8500/swagger-ui.html
ok，大工告成。
