如何在 Spring JPA 中回滾 OnetoOne 關系

Question

當我將數據插入數據庫時​​，我有三個實體類如果拋出任何異常，那么所有表值都應該回滾

服務等級：

    @Service
    @Transactional
    public class CustomerService  {
    
        private final CustomerDetailsRepo cdRepo;
        
        @Autowired
        public CustomerService(CustomerDetailsRepo cdRepo) {
            
            this.cdRepo = cdRepo;
            
        }
        public void saveCustomer(CustomerDetails customerDetails) 
        {   
            cdRepo.save(customerDetails);       
        }   
}

以上服務類是我的三個服務類之一

實體類：

@Entity
@Table(name = "tbl_Customer")
public class CustomerDetails {

    @Id
    @GeneratedValue
    @Column(name="Customer_Id")
    private Long custid;

    @Column(name="Customer_Name")
    private String customerName;
    
    @Column(name="Email")
    private String email;
    
    @Column(name="Address")
    private String address;
    
    @Column(name="Phone")
    private String phoneno;
    
    public CustomerDetails() {
    }
      
    @OneToOne(mappedBy = "customerDetails", fetch = FetchType.LAZY,
            cascade = CascadeType.ALL)
    private Product product;

//getters and setters
}

這里我用的是 OnetoOne 關系

Answer 1

有多種方法可以實現這一目標。 就像是 ：

public void saveCustomer(CustomerDetails customerDetails) {
  try {
    cdRepo.save(customerDetails);
  } catch (Exception e) {
    TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
  }
}

或者您可以使用 Transactional 標記您的方法。 例如：

@Transactional(rollbackFor = SQLException.class)
public void saveCustomer(CustomerDetails customerDetails) throws SQLException{   
 cdRepo.save(customerDetails);
throw new SQLException("Some error when saving");       
}
