1、数据准备
参考之前的项目，本文用订单商品的数据的做搜索
1)、订单表order_info，主要字段有：
id(主键)、order_no(订单号)、user_name(下单人)、consignee(收货人)、addresses(收货地址)、order_status(订单状态1~6)
created_at(下单时间)、store_id(店铺id)、order_amount(订单总额)
2)、订单商品表order_goods，主要字段有：
id(主键)、order_id(订单id)、goods_name(商品名称)、goods_spec(商品规格)、goods_price(商品价格)
3)、店铺表store，主要字段有：
id(主键)、store_name(店铺名称)
4)、测试数据：
5)、构造数据库模型，Order.php文件
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Log;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Arr;
use App\Models\OrderGoods;
/**
* @property mixed pay_type 支付方式 1支付宝， 2微信，3余额
* @property mixed user
*/
class Order extends Model
{
protected $table = 'order_info';
public $timestamps = false;
protected $fillable = ['order_no', 'store_id', 'user_id', 'user_name', 'consignee',
'phone', 'province', 'district', 'city', 'address', 'addresses', 'leave_msg', 'order_status', 'return_status',
'is_lock', 'goods_amount', 'order_amount', 'logistics_amount','discount_amount','commission_amount','reward_wheat', 'remark', 'pay_type', 'source',
'is_show', 'pay_at', 'delivery_at', 'finish_at', 'cancel_at', 'delete_at', 'created_at', 'updated_at'];
public function goods()
{
return $this->hasMany('App\Models\OrderGoods', 'order_id', 'id');
}
public function store(){
return $this->belongsTo('App\Models\Store','store_id','id');
}
public function toESArray()
{
// 只取出需要的字段
$arr = Arr::only($this->toArray(), [
'id',
'order_no',
'user_name',
'consignee',
'addresses',
'order_status',
'order_amount',
'created_at',
]);
$arr['store_name'] = $this->store->store_name;
// 只取出需要的 goods 字段
$arr['goods'] = $this->goods->map(function (OrderGoods $goods){
return Arr::only($goods->toArray(),['goods_name', 'goods_spec', 'goods_price']);
});
//随机生成属性
$arr['properties'] = collect($this->getProperties())->map(function($properties,$key){
return array_merge($properties, [
'search_value' => $properties['name'].':'.$properties['value'],
]);
});
return $arr;
}
//构造商品属性规格数据
public function getProperties(){
$params = [];
$params1 = [
["name" => "品牌名称", "value" => "金士顿"],
["name" => "品牌名称", "value" => "海盗船"],
["name" => "品牌名称", "value" => "三星"],
["name" => "品牌名称", "value" => "影驰"],
["name" => "品牌名称", "value" => "威刚"],
];
$params2 = [
["name" => "内存容量", "value" => "8GB"],
["name" => "内存容量", "value" => "4GB"],
["name" => "内存容量", "value" => "16GB"],
];
$params3 = [
["name" => "传输类型", "value" => "DDR4"],
["name" => "传输类型", "value" => "DDR3"],
];
$params[] = $params1[rand(0,4)];
$randNum = rand(1,3);
foreach($params2 as $k=> $val){
if($k<$randNum){
$params[] = $val;
}else{
break;
}
}
$params[] = $params3[rand(0,1)];
return $params;
}
}OrderGoods.php文件
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class OrderGoods extends Model
{
protected $table = 'order_goods';
protected $fillable = ['order_id','goods_id','sku_id','goods_name','goods_image',
'goods_num','original_price','goods_price','goods_spec','logistics_amount','receive_amount','goods_amount','is_after_sale','status'];
}Store.php文件
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Store extends Model
{
protected $table = 'store'; // 指定表
protected $fillable = ['id', 'phone_number', 'store_name', 'password', 'store_logo', 'store_domain_name', 'store_grade', 'store_duration', 'store_type', 'passed', 'refuse_reason', 'is_usable', 'remark', 'reason', 'invoice', 'payment_voucher', 'remember_token', 'submit_time', 'first_trial_time', 'upload_documents_time', 'pass_time', 'open_time'];
public function orders(){
$this->hasMany('App\Models\Order','store_id','id');
}
}2、创建索引orders
通过创建一个 Artisan 命令来实现，创建Elasticsearch目录，执行命令
php artisan make:command Elasticsearch/CreateIndex
CreateIndex.php文件内容
<?php
namespace App\Console\Commands\Elasticsearch;
use Illuminate\Console\Command;
class CreateIndex extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'es:create-index {index}';
/**
* The console command description.
*
* @var string
*/
protected $description = '创建Elasticsearch索引';
protected $index;
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
//删除之前创建的索引
$this->index = $this->argument('index');
if ($this->existIndex()) {
$this->deleteIndex();
$this->info('已删除索引：'.$this->index);
}
//创建索引
app('es')->indices()->create([
'index' => $this->index,
'body' => [
'settings' => [
'analysis' => [
'analyzer' => [
'ik_smart_synonym' => [
'type' => 'custom',
'tokenizer' => 'ik_max_word',
'filter' => ['synonym_filter'],
],
],
'filter' => [
'synonym_filter' => [
'type' => 'synonym',
'synonyms_path' => 'analysis/synonyms.txt',
],
],
],
],
]
]);
$this->info('已创建索引：'.$this->index);
}
/**
* @desc 检测索引
* @method existIndex
* @return bool
* @time 2020/8/7 17:05
*/
public function existIndex(){
return app('es')->indices()->exists(['index' => $this->index]);
}
/**
* @desc 删除索引
* @method deleteIndex
* @return array
* @time 2020/8/7 17:05
*/
public function deleteIndex(){
return app('es')->indices()->delete(['index' => $this->index]);
}
}创建索引时要先判断之前是否已创建，如果已创建就先删除后在重新创建，创建所以时settings设置了同义词配置，关于同义词的安装之前已经讲过，这里就不再叙述了。
执行命令创建orders索引
php artisan es:create_index orders
3、创建mappings
通过创建一个 Artisan 命令来实现，执行命令
php artisan make:command Elasticsearch/CreateMapping
CreateMapping.php文件内容
<?php
namespace App\Console\Commands\Elasticsearch;
use Illuminate\Console\Command;
class CreateMapping extends Command
{
/**
* The name and signature of the console command.
*
* @var string
*/
protected $signature = 'es:create-mapping {index}';
/**
* The console command description.
*
* @var string
*/
protected $description = '创建Elasticsearch映射';
protected $index;
/**
* Create a new command instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* @return mixed
*/
public function handle()
{
$this->index = $this->argument('index');
$params = $this->getParams();
app('es')->indices()->putMapping($params);
$this->info('已创建映射：'.$this->index);
}
public function getParams(){
$params = [
'index'=>$this->index,
'type'=>'_doc',
'custom'=>['include_type_name'=>true],
'body'=>[
'_doc'=>[
'properties'=>[
]
]
]
];
switch ($this->index){
case 'orders':
$params['body']['_doc']['properties'] = [
'id'=>['type'=>'integer'],
'order_no'=>['type'=>'keyword'],
'order_amount'=>['type'=>'scaled_float','scaling_factor'=>100],
'order_status'=>['type'=>'byte'],
'created_at'=>['type'=>'keyword'],
'user_name'=>['type'=>'text',"analyzer"=>"ik_max_word", "search_analyzer"=>"ik_smart_synonym"],
'consignee'=>['type'=>'text',"analyzer"=>"ik_max_word", "search_analyzer"=>"ik_smart_synonym"],
'store_name'=>['type'=>'text',"analyzer"=>"ik_max_word", "search_analyzer"=>"ik_smart_synonym"],
'addresses'=>['type'=>'text',"analyzer"=>"ik_max_word", "search_analyzer"=>"ik_smart_synonym"],
'goods'=>[
'type'=>'nested',
'properties'=>[
'goods_name'=>['type'=>'text',"analyzer"=>"ik_max_word", "search_analyzer"=>"ik_smart_synonym",'copy_to'=>'goodsName'],
'goods_spec'=>['type'=>'text',"analyzer"=>"ik_max_word", "search_analyzer"=>"ik_smart_synonym",'copy_to'=>'goodsSpec'],
'goods_price'=>['type'=>'scaled_float','scaling_factor'=>100]
]
],
'properties'=>[
'type'=>'nested',
'properties'=>[
'name'=>['type'=>'keyword','copy_to'=>'properties_name'],
'value'=>['type'=>'keyword','copy_to'=>'properties_value'],
'search_value'=>['type'=>'keyword']
]
]
];
break;
}
return $params;
}
}创建mapping要指定索引名称
Elasticsearch 的多字段匹配查询是不支持查询 Nested 对象的字段，如果不设置copy_to是查询不到数据的，所以这里加了copy_to参数，查询的时候可以通过copy_to参数值来查询数据
search_analyzer在搜索查询时，使用了自定义的ik_smart_synonym，可以同义词查询
执行命令
php artisan es:create_mapping orders
4、同步订单数据到Elasticsearch中
通过创建一个 Artisan 命令来实现，执行命令
php artisan make:command Elasticsearch/SyncOrders
SyncOrders.php文件内容
<?php
namespace App\Console\Commands\Elasticsearch;
use App\Models\Order;
use Illuminate\Console\Command;
class SyncOrders extends Command
{
protected $signature = 'es:sync-orders';
protected $description = '将订单数据同步到 Elasticsearch';
public function __construct()
{
parent::__construct();
}
public function handle()
{
// 获取 Elasticsearch 对象
$es = app('es');
Order::with(['goods'])
// 使用 chunkById 避免一次性加载过多数据
->chunkById(100, function ($orders) use ($es) {
$this->info(sprintf('正在同步 ID 范围为 %s 至 %s 的订单', $orders->first()->id, $orders->last()->id));
// 初始化请求体
$req = ['body' => []];
// 遍历订单
foreach ($orders as $order) {
// 将订单模型转为 Elasticsearch 所用的数组
$data = $order->toESArray();
$req['body'][] = [
'index' => [
'_index' => 'orders',
'_id' => $data['id'],
],
];
$req['body'][] = $data;
}
try {
// 使用 bulk 方法批量创建
$es->bulk($req);
} catch (\Exception $e) {
$this->error($e->getMessage());
}
});
$this->info('同步完成');
}
}执行命令
php artisan es:sync-orders
