如何在 Spring JPA 中回滚 OnetoOne 关系

Question

当我将数据插入数据库时​​，我有三个实体类如果抛出任何异常，那么所有表值都应该回滚

服务等级：

    @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);       
        }   
}

以上服务类是我的三个服务类之一

实体类：

@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
}

这里我用的是 OnetoOne 关系

有多种方法可以实现这一目标。 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 标记您的方法。 例如：

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