MongoDB方法抛出'org.springframework.data.mapping.MappingException'异常

Question

我有以下模型

@Builder
@Data
@Document(collection = "overdue")
public class MGOverdue {
@Id
private String id;
private HashMap<Integer, HashMap<Integer, Overdue>> overdueList;
}

repository.findById()抛出以下异常

Method threw 'org.springframework.data.mapping.MappingException' exception

Caused by: org.springframework.data.mapping.MappingException: No property b found on entity class .<package>.receipt.Overdue to bind constructor parameter to!

有什么建议请提
