我有两个桌子。一个是商人，另一个是地址。我正在验证地址表。商家和地址是一对多的关系。
这是我的商人表：
@Getter
@Setter
@Entity
@Table(name = "merchant")
public class Merchant extends Auditable<String> {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY) // Auto generate Id...
@Column(name = "id")
private Long id;
@NotBlank(message = "Id no is required")
@Size(min = 1, max = 20, message
= "Id No must be between 1 and 20 characters")
@Column(name = "id_no")
private String idNo;
@NotBlank(message = "Id type is required")
@Column(name = "id_type")
private String idType;
@NotBlank(message = "Email id is required")
@Email(message = "Email should be valid")
@Column(name = "email_id")
private String emailId;
@NotBlank(message = "Name is required")
@Size(min = 1, max = 40, message
= "Merchant name must be between 1 and 40 characters")
@Column(name = "name")
private String name;
@AssertTrue
@NotNull(message = "Status is required")
@Column(name = "status")
private boolean status;
@Column(name = "created_by")
private String createdBy;
@Column(name = "modified_by")
private String modifiedBy;
@ManyToMany(fetch = FetchType.LAZY, mappedBy="merchantSet")
@Getter(onMethod = @__( @JsonIgnore))
@Setter
private Set<Product> productSet = new HashSet<Product>();
@OneToMany(fetch = FetchType.LAZY,cascade = {CascadeType.MERGE}, mappedBy = "merchant")
@NotEmpty(message = "Contact is required")
private Set<Contact> contacts = new HashSet<Contact>(
0);
@OneToMany(fetch = FetchType.LAZY, cascade = {CascadeType.MERGE}, mappedBy = "merchant")
@NotEmpty(message = "Address is required")
private Set<Address> addresses = new HashSet<Address>(
0);
}
这是我的地址类别：
@Getter
@Setter
@Entity
public class Address extends Auditable<String> {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id")
private Long id;
@NotBlank(message = "Line1 is required")
@Column(name = "line_1")
private String line1;
@NotBlank(message = "Line2 is required")
@Column(name = "line_2")
private String line2;
@NotBlank(message = "Line3 is required")
@Column(name = "line_3")
private String line3;
@NotBlank(message = "City is required")
@Column(name = "city")
private String city;
@NotBlank(message = "Country is required")
@Column(name = "country")
private String country;
@NotBlank(message = "ZipCode is required")
@Column(name = "zip_code")
private String zipCode;
@NotBlank(message = "Type is required")
@Column(name = "type")
private String type;
@NotBlank(message = "Owner type is required")
@Column(name = "owner_type")
private String ownerType;
@Column(name = "created_by")
private Long createdBy;
@Column(name = "modified_by")
private Long modifiedBy;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "merchant_id", nullable = false)
@JsonIgnoreProperties({"hibernateLazyInitializer", "handler"})
@Getter(onMethod = @__( @JsonIgnore))
@Setter
private Merchant merchant;
}
当我将地址行更新为空值时，会引发错误：

我添加了句柄ConstraintViolationException来获取该异常消息。如何解决这个问题呢。我尝试了很多方法来处理此异常，但是没有用。抛出RollbackException。
我的商家更新服务是
public MerchantDTO updateMerchant(MerchantDTO merchantDTO, Long id) throws ClassNotFoundException, ConstraintViolationException {
Merchant merchant = (Merchant) transformService.convertToEntity(merchantDTO, Constant.MERCHANT_ENTITY_CLASS);
if(merchant.getAddresses().size() > 5) throw new MaximumValueExceptionHandler();
if(merchant.getAddresses().size() <= 0) throw new MinimumValueExceptionHandler();
if(merchant.getContacts().size() <= 0) throw new MinimumValueExceptionHandler();
if(merchant.getContacts().size() > 3) throw new MaximumValueExceptionHandler();
if (!merchantRepository.existsById(id)) throw new MerchantExceptionHandler();
Merchant oldMerchant = merchantRepository.findMerchantById(id);
if(merchantRepository.findByEmailId(merchant.getEmailId()) == null ||oldMerchant.getEmailId().equals(merchant.getEmailId())) {
oldMerchant.setCreatedBy(merchant.getCreatedBy());
oldMerchant.setEmailId(merchant.getEmailId());
oldMerchant.setIdNo(merchant.getIdNo());
oldMerchant.setIdType(merchant.getIdType());
oldMerchant.setModifiedBy(merchant.getModifiedBy());
oldMerchant.setName(merchant.getName());
oldMerchant.setStatus(merchant.isStatus());
merchant.getAddresses().forEach(address -> {
Merchant merchant1 = new Merchant();
if (address.getId() == null) {
merchant1.setId(id);
address.setMerchant(merchant1);
addressRepository.save(address);
}
if (!addressRepository.existsById(address.getId())) throw new AddressExceptionHandler();
Address oldAddress = addressRepository.findAddressById(address.getId());
oldAddress.setCity(address.getCity());
oldAddress.setCountry(address.getCountry());
oldAddress.setCreatedBy(address.getCreatedBy());
oldAddress.setLine1(address.getLine1());
oldAddress.setLine2(address.getLine2());
oldAddress.setLine3(address.getLine3());
oldAddress.setModifiedBy(address.getModifiedBy());
oldAddress.setOwnerType(address.getOwnerType());
oldAddress.setType(address.getType());
oldAddress.setZipCode(address.getZipCode());
merchant1.setId(id);
oldAddress.setMerchant(merchant1);
addressRepository.save(oldAddress);
});
merchant.getContacts().forEach(contact -> {
Merchant merchant1 = new Merchant();
if (contact.getId() == null) {
merchant1.setId(id);
contact.setMerchant(merchant1);
contactRepository.save(contact);
}
if (!contactRepository.existsById(contact.getId())) throw new ContactExceptionHandler();

oldContact.setContactNo(contact.getContactNo());
merchant1.setId(id);
oldContact.setMerchant(merchant1);
contactRepository.save(oldContact);
});
Merchant newMerchant = merchantRepository.save(oldMerchant);
return (MerchantDTO) transformService.convertToDto(newMerchant, Constant.MERCHANT_DTO_CLASS);
}
return null;
}
答案 0 :(得分：0)
@NotBlank（消息=“必须输入Line1”）抛出
javax.validation.ConstraintViolationException
但是从代码
catch (org.hibernate.exception.ConstraintViolationException e) {
System.out.println(e.getMessage());
}
您正在将其作为休眠异常捕获，因此将不会对其进行处理。
