spring-data-elasticsearch @Field注解中analyzer无效的解决方案

环境：

1、es 6.8

2、spring-boot-starter-data-elasticsearch 2.2.5 Release

之所以使用映射文件是因为@Field注解中的analyzer无效，跟踪了下代码发现使用spring-data-elasticsearch在创建es实体类对应的

elasticsearch映射时根本就没有使用@Field注解中的内容，包括名字！！！

最后的解决方案：

@Getter
    @Setter
    @Document(indexName="product",type="es-product",shards=3,replicas = 0)
    @Mapping(mappingPath="mapping/es-product.json")
    public class ESProduct {
    
        @Field
        String id;
    
        @Field(name="mainTitle")
        String mainTitle;
    
        @Field(name="subTitle")
        String subTitle;
    
        @Field(name="brandName")
        String brandName;
    
        @Field(name="categoryName")
        String categoryName;
    }

es-product.json映射文件内容如下所示

{
      "properties": {
        "id": {
          "type": "keyword"
        },
        "mainTitle": {
          "type": "text",
          "analyzer": "ik_max_word",
          "search_analyzer": "ik_max_word"
        },
        "brandName": {
          "type": "keyword"
        },
        "categoryName": {
          "type": "keyword"
        }
      }
    }
