Я столкнулся со следующей ошибкой во время запуска моего приложения Spring Boot: < /p>
Error starting ApplicationContext.
org.springframework.beans.factory.UnsatisfiedDependencyException:Error creating bean with name 'feedController'
Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'productService'
Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'productRepository' defined in team.capybara.backend.spring.controllers.repositories.ProductRepository defined in @EnableJpaRepositories declared on Main: Cannot resolve reference to bean 'jpaSharedEM_entityManagerFactory' while setting bean property 'entityManager'
< /code>
Я прочитал много статей и нашел информацию, которую я должен вручную настроить 'EntityManagerFactory', и это помогло мне с моей первоначальной проблемой: < /p>
Error starting ApplicationContext.
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: jakarta/persistence/PersistenceUnitTransactionType
< /code>
Но я должен сказать, что мои классы организации написаны неправильно. По -видимому, есть проблемы в OneTomany и других связях.@Entity
@Table(name="Products")
public class Product {
@Id
@Column(name="id", nullable = false, unique = true)
private String id;
@OneToOne
@JoinColumn(name = "product_type_id")
private ProductType productType;
@Column(name="shelf_life", nullable = false)
private Date shelfLife; //last day of life
@Column(name="price", nullable = false)
private int price; // final price of product
@Column(name="discount", nullable = false)
private int discount; // discount amount in monetary units
@Column(name="is_sold", nullable = false)
private int isSold; //0 - false; 1 - true
public Product() {
}
public Product(ProductType productType,Date shelfLife,int price,int discount,int isSold){
this.id = (UUID.randomUUID()).toString();
this.productType = productType;
this.shelfLife = shelfLife;
this.price = price;
this.discount = discount;
this.isSold = isSold;
}

Класс конфигурации, который помог мне сделать Advance < /p>
@Configuration
public class AppConfig {
@Bean(name="entityManagerFactory")
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
return sessionFactory;
}

Just Repository: < /p>
@Repository
public interface ProductRepository extends JpaRepository {
}
