Как я могу исправить данные весенней загрузки jpa UnsatisfiedDependencyException

1 голос
/ 09 февраля 2020

Я создал одно весеннее загрузочное веб-приложение с использованием технологий Spring Web, jpa / hibernate и lombok. Но когда я бегу, я получаю следующую ошибку. Я создал пустую базу данных с именем 'lombokdb' для mysql и связал ее в разделе свойств приложения. Я искал ошибку, но не мог понять, что это было. Есть ли кто-нибудь, кто может сделать предложения?

Сообщение об исключении указывает на класс SchoolRepository, и я не вижу, чтобы вы добавили это в описание. Исключение гласит: 

Error creating bean with name 'schoolRepository': Invocation of init method failed; 
nested exception is java.lang.IllegalArgumentException: Failed to create query for 
method public abstract java.util.List
com.lombok.repository.SchoolRepository.findByPlateCode(java.lang.String)! 
No property plateCode found for type School!

В соответствии с вышеуказанной ошибкой говорится, что в школьном классе нет свойства с именем plateCode.

. Вы можете посмотреть на Spring Data. JPA документы для получения дополнительной справки
