我有一个Person类：

@Document(indexName = "person")
@Data
@EqualsAndHashCode(callSuper = true)
public class Person extends BaseEntity implements Serializable {

  @Field(type=FieldType.Keyword)
  private String firstName;

  @Field(type=FieldType.Keyword)
  private String lastName;

  @MultiField(
      mainField = @Field(type = FieldType.Keyword),
      otherFields = {
          @InnerField(type = FieldType.Text, suffix = "ngrams", analyzer = "ik_max_word", searchAnalyzer = "ik_smart")
      })
  private String fullName;

  @Field
  private String maidenName;
}

我有一个在启动时创建索引的现有代码：

final IndexOperations indexOperations = this.elasticsearchOperations.indexOps(clazz);
      indexOperations.putMapping();

现在，我有一个需求，从它生成Map，并创建Map一次。有人能帮助我如何将它与现有的代码集成，以包括字段的Map，使他们成为静态的？
