在春季启动休眠搜索中索引时屏蔽敏感数据

我使用的是SpringBoot2.0.2和HibernateSearch5.10.2。 我的实体类如下:

    @Entity
    @Table(name = "CUSTOMERS")
    @Indexed(index = "indexes_customer")
    @JsonIgnoreProperties(ignoreUnknown = true)
    public class Beneficiary implements Serializable {
        private static final long serialVersionUID = 1L;
        @Id
        @Column(name = "ID", nullable = false)
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private long id;

        @Basic
        @Column(name = "CARD_NUMBER", length = 18)
        @Field(analyze = Analyze.NO, store = Store.YES)
        @SortableField
        private String cardNumber;

        @Basic
        @Column(name = "FULL_NAME", length = 60)
        @Field(analyze = Analyze.NO, store = Store.YES)
        @SortableField
        private String fullName;
        //Getters & setters

卡片数据以纯文本形式保存,但在显示给前台用户时会被屏蔽。但是,我想在索引时隐藏卡号。 目前,我的索引如下:

{
  "_index": "indexes_customer",
  "_type": "mypackage.Customer",
  "_id": "24",
  "_version": 3,
  "_score": 1,
  "_source": {
    "id": "24",
    "name": "Customer Name",
    "cardNumber": "1234567891011"
  }
}

我希望它看起来更像这样:

{
  "_index": "indexes_customer",
  "_type": "mypackage.Customer",
  "_id": "24",
  "_version": 3,
  "_score": 1,
  "_source": {
    "id": "24",
    "name": "Customer Name",
    "cardNumber": "1234******1011"
  }
}

谢谢
