+ * Spring Data通过注解来声明字段的映射属性，有下面的三个注解：

+ * - `@Document` 作用在类，标记实体类为文档对象，一般有两个属性
+ *      - indexName：对应索引库名称
+ *      - type：对应在索引库中的类型
+ *      - shards：分片数量，默认5
+ *      - replicas：副本数量，默认1
+ * - `@Id` 作用在成员变量，标记一个字段作为id主键
+ * - `@Field` 作用在成员变量，标记为文档的字段，并指定字段映射属性：
+ *      - type：字段类型，是是枚举：FieldType
+ *      - index：是否索引，布尔类型，默认是true
+ *      - store：是否存储，布尔类型，默认是false
