Java Pojo验证工作。博科（科特林）没有'；T为什么？

我有一个POJO并启用了JSR验证

出于演示的原因，我已经将整个项目重新实现为Kotlin，我想演示一下验证方面。除了，在科特林，它根本不起作用，原因也不清楚。有人能解释一下我遗漏了什么吗

要启用验证，请使用Java：

@Configuration
@RequiredArgsConstructor
public static class ValidationConfiguration extends RepositoryRestConfigurerAdapter {

    private final Validator jsr303Validator;

    @Override
    public void configureValidatingRepositoryEventListener(ValidatingRepositoryEventListener validatingListener) {
        //bean validation always before save and create
        validatingListener.addValidator("beforeCreate", jsr303Validator);
        validatingListener.addValidator("beforeSave", jsr303Validator);

    }


}

POJO：

结果（预期的java版本）：

现在，作为Kotlin Poko：

职位/雇员

结果（201已创建）：

在

数据类A（@Email val Email:String）

中，默认情况下，注释应用于构造函数参数。换句话说，它相当于：

class A{
  public A(@Email String email) { ... }
}

在本例中，您希望将注释应用于字段，因此需要编写：

data class A(@field:Email val email: String)

@Entity
data class Employee(@Pattern(regexp = "[A-Za-z0-9]+")
                    @Size(min = 6, max = 32)
                    val name: String,
                    @Email
                    @NotNull
