java - 仅在重构包名称之后，才考虑在配置中定义 * 类型的 bean

Question

这段代码一直工作得很好，我只是重构了包名称，spring 上下文不能再注入(inject)这个 bean。顺便说一句，我确信新的包名称仍然与 @ComponentScan 范围匹配

@Repository("tenantsConfigRepository")
public interface TenantsConfigRepository extends JpaRepository<TenantsConfig, Long> {
    public TenantsConfig deleteByName(String name);
}

@Service
public class TenantsConfigService {

    TenantsConfigRepository tenantsConfigRepository;


    @Autowired
    public TenantsConfigService(TenantsConfigRepository tenantsConfigRepository) {
        this.tenantsConfigRepository = tenantsConfigRepository;
    }

    public List<TenantsConfig> findAll() {
        return tenantsConfigRepository.findAll();
    }

    public Optional<TenantsConfig> find(long id) {
        return tenantsConfigRepository.findById(id);
    }

    public void saveOrUpdate(TenantsConfig tenantsConfig) {
        tenantsConfigRepository.save(tenantsConfig);
    }

    public void delete(TenantsConfig tenantsConfig) {
        tenantsConfigRepository.delete(tenantsConfig);
    }

    public void deleteByName(String name) {
        tenantsConfigRepository.deleteByName(name);
    }
}

应用程序无法启动并打印此文本

感谢大家的回复，我明白了，我正在使用配置类中的数据源，这些配置的范围仅限于用于特定的包，我只是更改了basePackages属性以匹配新的包名称。

@Configuration
@EnableJpaRepositories(basePackages = "com.example.admin", entityManagerFactoryRef = "adminEntityManager", transactionManagerRef = "adminTransactionManager")

和

em.setPackagesToScan("com.example.admin.entity");

em 指的是 EntityManager
