Sales Order save not working for existing Customer but working for new Customer

@Entity
@Table(name = "sales_order")
@EntityListeners(AuditingEntityListener.class)
public class SalesOrder extends Auditable<String>  implements Serializable {
    

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private Long id;
    
    @OneToOne(fetch = FetchType.EAGER,cascade=CascadeType.ALL)
    @JoinColumn(name = "customer_id", nullable = false)
    private Customer customer;
    

@Entity
@Table(name = "customer")
@EntityListeners(AuditingEntityListener.class)
public class Customer extends Auditable<String>  implements Serializable {
    

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private Long id;
    
    @OneToOne(mappedBy="customer",cascade={CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST,CascadeType.REFRESH})
    private SalesOrder salesOrder;

SalesOrder salesOrder = new SalesOrder();
            Branch branch = BranchContextHolder.getCurrentBranch();
            String nextSequense = null;
            if(salesOrderDto.getId()==null) {
                salesOrder = new SalesOrder(salesOrderDto);
                salesOrder.setBranch(branch);
                if(customerRepository.existsByPhone(salesOrderDto.getCustomer().getPhone())) {
                    Customer customer = customerRepository.findCustomerByPhone(salesOrderDto.getCustomer().getPhone());
                    customer.setSalesOrder(salesOrder);
                    salesOrder.setCustomer(customer);
                }
                nextSequense = sequenceService.getNextSequense(branch.getId(),module.getId());
                salesOrder.setUid(nextSequense);
            }

//save sales order
salesOrder = salesOrderRepository.save(salesOrder);

On save getting error:

detached entity passed to persist: com.jee.cms.app.customer.model.Customer; nested exception is org.hibernate.PersistentObjectException: detached entity passed to persist: com.jee.cms.app.customer.model.Customer

Anything I am missing?

CodePudding user response：

Try annotating your method with @Transactional. Then then Customer won't get detached within the method.
