**相关说明**

**索引文档，需要对字段进行自定义映射**

@Data
    @Document(indexName = "people3",type = "_doc")
    public class People {
    
        @Id
        private Integer id;
    
        @Field(type = FieldType.Keyword)
        private String name;
    
        @Field(type = FieldType.Text,analyzer = "ik_smart")
        private String description;
    
        @Field(type = FieldType.Text,analyzer = "hanlp")
        private String description2;
    
        @Field(type = FieldType.Text,analyzer = "pinyin")
        private String description3;
    
        @MultiField(mainField = @Field(type = FieldType.Text,analyzer = "ik_smart"),
                otherFields = @InnerField(suffix = "inner", type = FieldType.Text, analyzer = "pinyin"))
        private String description4;
    
        @MultiField(mainField = @Field(type = FieldType.Text,analyzer = "hanlp"),
                otherFields = @InnerField(suffix = "inner",type = FieldType.Text,analyzer = "pinyin"))
        private String description5;
    }

**默认情况下，springboot data elasticsearch使用如下映射方式，自定义映射不起作用**

**解决办法：使用elasticsearchRestTemplate手动添加映射**

@Resource
        private ElasticsearchRestTemplate elasticsearchRestTemplate;
    
        @PostConstruct
        public void init(){
            elasticsearchRestTemplate.putMapping(People.class);
        }

**添加此操作后，自定义映射生效**
