Ошибка создания bean-компонента с именем «com.budthapa.StatusTest»: неудовлетворенная зависимость, выраженная через поле «statusUpdateDao»

Question

Я пытаюсь протестировать операцию сохранения с помощью JUnit в классе StatusUpdate, но получил следующую ошибку, указывающую на ошибку при создании компонента в тесте класс. Я изучаю весенний ботинок.

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.budthapa.StatusTest': Unsatisfied dependency expressed through field 'statusUpdateDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.budthapa.domain.StatusUpdateDao' available: expected at least 1 bean which qualifies as autowire candidate.

Answer 1

Попробуйте добавить @EnableJpaRepositories("com.budthapa.domain") в SocialNetworkApplication.class

@SpringBootApplication 
@EnableJpaRepositories("com.budthapa.domain") 
@EntityScan("com.budthapa.domain") 
public class SocialNetworkApplication {  
    public static void main(String[] args) { 
     SpringApplication.run(SocialNetworkApplication.class, args); 
    } 
}
