spring boot:ReactiveMongo未能将排序规则信息添加到索引规范以创建索引（@索引）

Question

我正在使用Spring Boot webflow和Spring data reactive mongob。我有一个用@Document注释的用户类，它实现了User细节。问题是我有一个带有@Indux（唯一=true）的username字段。当应用程序启动时，即使在数据库上创建索引，它也会抛出下面的错误。

以下是课程：

public abstract class GenericEntity<Tid> {
    
    abstract public Tid getId();
    
}

@Data
@Document(collection = "users")
@FieldDefaults(level = AccessLevel.PROTECTED)
@NoArgsConstructor
@AllArgsConstructor
public abstract class User extends GenericEntity<String> implements UserDetails {


    @Id
    String id;

    @Size(max = 63)
    @NotBlank(message = "First name is missing")
    String firstName;

    @Size(max = 63)
    @NotBlank(message = "Last name is missing")
    String lastName;

    @NotBlank
    @Size(min = 5, max = 40)
    @Email(message = "Invalid email address")
    @Indexed(unique = true)
    String username;

    @NotBlank
    @Size(min = 8, max = 255)
    @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
    String password;

    @NotNull
    Boolean enabled = true;

    @NotEmpty
    List<Role> roles;
}

@Data
@Document(collection = "users")
@TypeAlias(value = "com.abcd.photograph.Photograph")
public class Photograph extends User {

    @NotNull
    Date birthDate;
    
}

错误：

从错误消息"排序规则：{locale："用户"}"我假设您在某个地方设置了排序规则。尝试在您的代码中搜索。
