Mam problem z zapytaniem @Query z wykorzystaniem Join
Do rzeczy:
Takie zapytanie :
@Query("SELECT new pl.tabele.feature.product.DTO.ProductDetailsDTO(c.customerId, c.name, p.unit, p.price, od.quantity, sum(p.price * od.quantity)) " +
"FROM Customer c, Product p, Orders o, OrderDetails od " +
"WHERE c.customerId = :id " +
"AND c.customerId = o.customerId " +
"AND p.productId = od.productId " +
"AND o.orderId = od.orderId " +
"GROUP BY c.customerId, c.name, c.contactName, c.city, c.country, " +
"p.productId, p.name, p.unit, p.price, od.quantity")
List<ProductDetailsDTO> findProductDetailsList(@Param("id") Long id);
To zapytanie działa pięknie zwraca mi Liste ProductDetailsDTO
Ale chciałem stworzyć to samo zapytanie z wykorzystaniem funkcji JOIN
I niestety nie umiem sobie z tym poradzić ponieważ :
@Query("SELECT new pl.tabele.feature.product.DTO.ProductDetailsDTO(c.customerId, c.name, product.unit, product.price, orderDetails.quantity, sum(product.price * orderDetails.quantity)) " +
"FROM Customer c " +
"JOIN c.customerId orders " +
"JOIN product.productId orderDetails " +
"JOIN orders.orderId orderDetails " +
"WHERE c.customerId = :id " +
"GROUP BY c.customerId, c.name, c.contactName, c.city, c.country, " +
"product.productId, product.name, product.unit, product.price, orderDetails.quantity, (product.price * orderDetails.quantity)")
List<ProductDetailsDTO> findProductDetailsList(@Param("id") Long id);
Takie zapytanie zwraca mi błąd:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customerController' defined in file [D:\Projekty\3\tabele\target\classes\pl\tabele\controller\CustomerController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'customerService' defined in file [D:\Projekty\3\tabele\target\classes\pl\tabele\feature\customer\service\CustomerService.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List pl.tabele.feature.customer.repository.CustomerRepository.findProductDetailsList(java.lang.Long)!
