問題: 我在Dao層用了 Area findByProvinceAndCityAndDistrict(String province, String city,String district); 這種寫法方式是Repository默認的檢索方式, 記憶中只能返回一個對象, 但是這裏好像並不是這樣..

repository返回值超過一個

暫時態對象無法保存異常

No property toPredicate found for type User!報錯

repository返回值超過一個

.WebDelegatingSubject cannot be cast to cn.itcast.bos.domain.system.User
