如何在 Spring JPA 中回滚 OnetoOne 关系

Question

I Have Three Entity Classes while I'm Inserting Data into Database If Any Exception is Thrown then All table Values are Should be Rollback

Service Class:

    @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);       
        }   
}

The Above Service Class is One of my Three Service class

Entity Class:

@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
}

Here I'm used OnetoOne Relationship

There are multiple ways you can achieve this. Something like :

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

Or you can mark your method with Transactional. Eg:

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