我有以下Dto类结构

public class MyDto {
    @Email
    private String mail;

    public String getMail() {
        return mail;
    }

    public void setMail(String mail) {
       this.mail = mail;
   }
}

@Generated(value = "org.openapitools.codegen.languages.SpringCodegen", date = "2023-11-01T17:12:49.075897700+03:00[Europe/Moscow]")
public class CustomUserPatchRequestDto {
    @JsonProperty("myDto")
    @Valid
    private JsonNullable<@Valid MyDto> myDto;
    // getter and setter
    ...

字符串
以及以下控制器

@RestController
@Validated
class MyController() {
  @RequestMapping(
        method = [PATCH],
        value = ["/userscustom/{id}"],
        produces = ["application/json"],
        consumes = ["application/merge-patch+json"]
    )
    fun patchUserCustom(
        @Parameter(name = "id", description = "", required = true,in= PATH) @PathVariable("id") id: String?
     @Valid @RequestBody userPatchRequestDto: CustomUserPatchRequestDto?
    ): ResponseEntity<String?>? {
        return ResponseEntity.ok("ok")
    }

型
当我发送身体请求时

{
  "myDto": {
    "mail": "12sdfdsf3"
  }
}

型
我得到错误响应：

{
  "code": 500,
  "reason": "JSR-303 validated property 'myDto.mail' does not have a corresponding accessor for Spring data binding - check your DataBinder's configuration (bean property versus direct field access)"
}

型
我该怎么补救？
我尝试在所有地方添加@Valid注解，但没有成功

更新

尝试在控制器中添加InitBinder：

@InitBinder
private fun activateDirectFieldAccess(dataBinder: DataBinder) {
    println("Working Inner")
    dataBinder.initDirectFieldAccess();
}

型
还尝试添加分隔类：

@ControllerAdvice
class CustomControllerAdvice {

    @InitBinder
    private fun activateDirectFieldAccess(dataBinder: DataBinder) {
        println("Working Inner")
        dataBinder.initDirectFieldAccess();
    }
}

型
在这两种情况下，

Working Inner

型
所以这段代码被执行了。
但不幸的是，我仍然有同样的问题。

附注

stacktrace是：

非常奇怪的事情，如果我传递正确的电子邮件，那么我看不到任何错误，一切都很好。所以问题只发生在我传递无效的电子邮件和异常文本和类型的问题

问题出在JsonNullable的某个地方。如果你简单地将一个字段声明为MyDto，那么spring将抛出正确的验证异常。
所以当出现验证错误时，spring会尝试获取myDto.mail字段的值，但是不能这样做，因为通过myDto字段的反射，它接收到JsonNullabl e类型而不是MyDto。您可以通过重写getRejectedValue方法来绕过此行为。最好将其余代码保留为原始代码ValidationAutoConfiguration.class个

@Configuration
class ValidationConfig {
    @Bean
    @Primary
    fun defaultValidator(applicationContext: ApplicationContext?): LocalValidatorFactoryBean? {
        val factoryBean = object : LocalValidatorFactoryBean() {
            override fun getRejectedValue(field: String, violation: ConstraintViolation<Any>, bindingResult: BindingResult): Any? {
                return violation.getInvalidValue()
            }
        }
        val interpolatorFactory = MessageInterpolatorFactory(applicationContext)
        factoryBean.messageInterpolator = interpolatorFactory.getObject()
        return factoryBean
    }
}

12sdfdsf3是一个无效的电子邮件，它会抛出一个错误，因为你有@Email注解，所以你的值应该看起来像**email protected(https://stackoverflow.com/cdn-cgi/l/email-protection)**。你需要向这个字段传递有效的值。
