Java 原因：org.springframework.data.mapping.PropertyReferenceException:找不到类型日志的属性OrderByDateAddedEsc

我不断地发现这个错误：

原因：org.springframework.data.mapping.PropertyReferenceException:找不到类型日志的属性OrderByDateAddedEsc

我似乎不明白为什么它不起作用。findallogs（）方法工作正常

有什么想法吗？ 任何帮助都将不胜感激。多谢各位

LogRepository.java

package ma.polytechnique.cctv.repository;

import java.util.List;

import org.springframework.data.jpa.repository.JpaRepository;

import ma.polytechnique.cctv.model.Log;

public interface LogRepository extends JpaRepository<Log, Long> {
    public List<Log> findAllByOrderBydateaddedDesc();

}

你试过大写日期吗？findAllByOrderByDateaddedDesc@MaciejKowalski就这样！非常感谢。我认为该方法中必须包含实体attritibute的名称，这就是我将其写成小写的原因
