春季数据mongo-在课程上找不到属性“状态” ...您是说：状态？

Question

我正在使用Spring mongo数据，并且没有任何原因出现很多此类错误。服务器启动后，三十分钟后开始引发这些错误。

该实体包含显然找不到的属性：

org.springframework.data.mapping.context.InvalidPersistentPropertyPath: No property 'status' found on class com.parozlabs.tx.api.books.Book! Did you mean: status?

实体：

 @Document(collection = "books")
 @JsonInclude(JsonInclude.Include.NON_NULL)
 public class Book implements Resource {

    @Id
    private ObjectId id;
    private long created;
    private long startDate;
    private BookStatus status;

 <getters and setters>
 ...
 }

存储库

public interface BooksRepositoryCustom extends
PagingAndSortingRepository<Book, String> {

    // Get all books, for admins
    List<Book> findByStatus(BookStatus statuss);

}
