Elasticsearch 6：拒绝映射更新，因为最终映射将具有多种类型 [英] Elasticsearch 6: Rejecting mapping update as the final mapping would have more than 1 type

问题描述

我正在尝试将项目转换为使用最新的Elasticsearch 6，并且遇到了这个问题。我不知道问题是产品还是产品。在我的映射和属性中，我指定了产品，因此我不确定为什么在尝试为产品建立索引时会出现此错误。

I'm trying to convert a project to use the latest Elasticsearch 6 and am having this problem. I don't know if the problem is "Product" vs "product". In my mappings and attributes I specify "products", so I am not sure why I get this error when I try to index a product.

错误：

无效的NEST响应是由对PUT的不成功的低级调用生成的：
/ products / products / 1？pretty = true& error_trace = true

Invalid NEST response built from a unsuccessful low level call on PUT: /products/products/1?pretty=true&error_trace=true

拒绝将映射更新更新为[产品]，因为最终映射将使
具有不止一种类型：[产品，产品]

"Rejecting mapping update to [products] as the final mapping would have more than 1 type: [Product, products]"

请求：

{
  "id": 1,
  "warehouseId": 0,
  "productStatus": 1,
  "sku": "102377",
  "name": "Name",
  "shortDescription": "Description",
  "longDescription": "Description",
  "price": 37.3200
}

我的代码：

    [ElasticsearchType(Name = "products")]
    public class Product : BaseEntity
    {
        [Key]
        public int Id { get; set; }
        public int WarehouseId { get; set; }
        [Display(Name = "Product Status")]
        public Enums.ProductStatus ProductStatus { get; set; }
        [Required, StringLength(10)]
        public string Sku { get; set; }
        [Required, StringLength(200)]
        public string Name { get; set; }
        [StringLength(500), Display(Name = "Short Description")]
        public string ShortDescription { get; set; }
        [DataType(DataType.MultilineText), Display(Name = "Long Description")]
        public string LongDescription { get; set; }
        [Column(TypeName ="Money")]            
        public Nullable<decimal> Price { get; set; }
    }

connection.DefaultMappingFor<Product>(m => m.IndexName("products"));

推荐答案

这是因为ES 6发生了重大变化。 x：删除了映射（即使为了向后兼容，您仍然可以在路径中指定映射），因此实际上将索引限制为单一类型。

This is because of a breaking change in ES 6.x: mappings were removed (even if for backward compatibility you can still specify it in the path) thus de facto limiting the index to a single type.
