英文:
detached entity passed to persist - springboot
问题
销售订单保存对于现有客户不起作用，但对于新客户起作用
@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 nextSequence = 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);}nextSequence = sequenceService.getNextSequence(branch.getId(), module.getId());salesOrder.setUid(nextSequence);}// 保存销售订单salesOrder = salesOrderRepository.save(salesOrder);
在保存时出现错误：
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
我漏掉了什么吗？
英文:
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 ordersalesOrder = 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?

尝试使用@Transactional注解您的方法。然后，Customer在方法内部将不会变为游离状态。
英文:
Try annotating your method with @Transactional. Then then Customer won't get detached within the method.

这种类型的错误是因为具有相同的id（@id列值）的多个条目被找到而引发的。
英文:
This type of error arise when more then one entry found with same id (@id column value) .
