es批量导入进一对多的数据

es批量导入进一对多的数据

我有一个产品表

一个产品对应多个属性名

一个属性名对应多个属性值

一个产品还对应一个分类名称

   控制层

@ApiOperation(value = "导入所有产品信息数据库中商品到ES")
@RequestMapping(value = "/importAll", method = RequestMethod.POST)
@ResponseBody
public CommonResult<Integer> importAllList() {
    int count = esProductService.importAll();
    return CommonResult.success(count);
}

业务实现类

@Autowired
private EsProductDao productDao;
@Autowired
private EsProductRepository productRepository;

@Override
public int importAll() {
　　　//从库中查询出数据
    List<EsProduct> esProductList = productDao.getAllEsProductList(null);
　　//将数据导入到es中
    Iterable<EsProduct> esProductIterable = productRepository.saveAll(esProductList);
    Iterator<EsProduct> iterator = esProductIterable.iterator();
    int result = 0;
    while (iterator.hasNext()) {
        result++;
        iterator.next();
    }
    return result;
}

mybatis中getAllEsProductList的mapper.xml

<mapper namespace="com.macro.mall.search.dao.EsProductDao">
    <resultMap id="esProductListMap" type="com.macro.mall.search.domain.EsProduct">
        <id column="productId" jdbcType="BIGINT" property="id" />
        <result column="productSn" jdbcType="VARCHAR" property="productSn"/>
        <result column="brandId" jdbcType="BIGINT" property="brandId"/>
        <result column="brandName" jdbcType="VARCHAR" property="brandName"/>
        <result column="productCategoryId" jdbcType="BIGINT" property="productCategoryId"/>
        <result column="productName" jdbcType="VARCHAR" property="productName"/>
        <result column="subTitle" jdbcType="VARCHAR" property="subTitle"/>

            <collection property="attributeValues" ofType="com.macro.mall.search.domain.EsProductAttributeValue" javaType="java.util.ArrayList">

                <result column="pavProductAttributeValue" property="value" jdbcType="VARCHAR"/>
            </collection>
        </collection>
    </resultMap>
    <select id="getAllEsProductList" resultMap="esProductListMap">
        SELECT
        p.id productId,
        p.product_sn productSn,

        p.keywords keywords,
        pav.id pavProductAttributeValueId,
        pav.`value` pavProductAttributeValue,
        pa.id paProductAttributeId,
        pa.`name` paProductAttributeName,
        pc.id pcProductCategoryId,
        pc.`name` pcProductCategoryName
        FROM pms_product p
        LEFT JOIN pms_product_attribute_value pav ON p.id = pav.product_id
        LEFT JOIN pms_product_attribute pa ON pav.product_attribute_id= pa.id
        LEFT JOIN pms_product_category pc ON p.`product_category_id` = pc.`id`
        WHERE delete_status = 0 AND publish_status = 1
        <if test="id!=null">
            and p.id=#{id}
        </if>
    </select>
</mapper>

自定义的接口productRepository

public interface EsProductRepository extends ElasticsearchRepository<EsProduct, Long> {

}

这个是我的产品实体类

@Document(indexName = "product", type = "productInfo",shards = 1,replicas = 0)
public class EsProduct implements Serializable {

    private static final long serialVersionUID = 2372551074091780419L;
    @Id
    private Long id;
    @Field(type = FieldType.Keyword)
    private String productSn;
    private Long brandId;
    @Field(type = FieldType.Keyword)
    private String brandName;
    private Long productCategoryId;
    @Field(type = FieldType.Keyword)
    private String productName;
    @Field(analyzer = "ik_max_word",type = FieldType.Text)
    private String subTitle;
    private BigDecimal price;
    @Field(analyzer = "ik_max_word",type = FieldType.Text)
    private String keywords;

    @Field(type =FieldType.Nested)
    private List<EsProductAttribute> attributeList;

    @Field(type =FieldType.Nested)
    private EsProductCategory productCategorie;

这个是我的产品属性实体类

public class EsProductAttribute implements Serializable {

    private static final long serialVersionUID = 4965902919813623705L;
    @Id
    private Long id;

    @Field(type = FieldType.Keyword)
    private String paProductAttributeName;//属性名称

    @Field(type =FieldType.Nested)
    private List<EsProductAttributeValue> attributeValues;

这个是我的产品属性值实体类

public class EsProductAttributeValue implements Serializable {
    private static final long serialVersionUID = 6713756365860464751L;

    private Long id;
    private Long productAttributeId;
    //属性值
    @Field(type = FieldType.Keyword)
    private String value;

上面三个实体类都提供get和set方法

操作之后,添加成功

{
  "code": 200,
  "message": "操作成功",
  "data": 17
}
