我正在使用Spring Boot 2.1.11，Spring DATA REST，休眠。我正在尝试使JRS 303与SDR一起使用，以便获取验证错误的JSON响应。
到目前为止，它仍然有效，但仅当我执行POST时，当我执行PATCH时，我才收到意外响应。似乎ConstraintViolationException已按照here的说明包装。
给出一个完整的场景，这是我的配置：

这是bean的第一部分：

@EntityListeners(ContactListener.class)
@Table(indexes = {@Index(name = "idx_enabled", columnList = "enabled"), @Index(name = "idx_name", columnList = "name")})
@ScriptAssert.List({
//CHECK TAX CODE VALIDITY
@ScriptAssert(lang = "javascript", script = "_.taxCode != null && _.taxCode != '' && _.personType=='NATURAL_PERSON'?_.isTaxCodeValid(_.taxCode,_.country):true", alias = "_", reportOn = "taxCode", message = "{contact.invalid.taxcode}"),
//CHECK VAT NUMBER VALIDITY
@ScriptAssert(lang = "javascript", script = "_.vatNumber != null && _.vatNumber != '' && _.personType=='LEGAL_PERSON'?_.isVatNumberValid(_.vatNumber,_.country):true", alias = "_", reportOn = "vatNumber", message = "{contact.invalid.vatNumber}")
})
@Data
@EqualsAndHashCode(callSuper = true, onlyExplicitlyIncluded = true)
@AllArgsConstructor
@Builder
@ToString(callSuper = true)
public class Contact extends AbstractEntity {
@Builder.Default
@Audited
@NotNull
@Column(nullable = false, columnDefinition = "VARCHAR(255) DEFAULT 'LEGAL_PERSON'")
@Enumerated(EnumType.STRING)
private PersonType personType = PersonType.LEGAL_PERSON;
@Audited
@NotEmpty
@Size(min = 3, max = 255)
@Column(nullable = false)
private String name;
@OneToOne(cascade = CascadeType.ALL, orphanRemoval = true, fetch = FetchType.EAGER)
private Account account;
@Audited
@NotBlank
private String address;
但是，当我执行POST保存该实体时出现一些错误时，我得到了类似这样的内容：
{"errors":[{"entity":"Contact","property":"address","invalidValue":null,"message":"Il campo non può essere vuoto. Inserire un valore valido e ripetere l'operazione."},{"entity":"Contact","property":"personType","invalidValue":null,"message":"Il campo non può essere vuoto. Inserire un valore valido e ripetere l'operazione."},{"entity":"Contact","property":"city","invalidValue":null,"message":"Il campo non può essere vuoto. Inserire un valore valido e ripetere l'operazione."}]}
很好。当我用表格中的一些错误进行PATCH时，我得到以下答复：
{"timestamp":"2020-01-08T19:42:31.633+0000","status":400,"error":"Bad Request","exception":"org.springframework.http.converter.HttpMessageNotReadableException","message":"Cod. errore [494-577].

这是错误的。在第一种情况下，异常是从@ExceptionHandler(DataIntegrityViolationException.class)的方法捕获的，在第二种情况下是从handleHttpMessageNotReadable()的方法捕获的。
您是否有任何提示以正确的方式向我指出解决问题？
您可以使用扩展名]的[C0 [使用ProblemHandling，ValidationAdviceTrait的MethodArgumentNotValidAdviceTrait。您可以使用ProblemBuilder和标题，状态代码，详细信息等自定义消息。还可以使用ConstraintViolationAdviceTrait处理其他异常。两种方法POST和PATCH都可以正常工作。
