为什么在使用 HibernateValidator 时无法获取 ${validatedValue}

如何解决为什么在使用 HibernateValidator 时无法获取 ${validatedValue}

我想通过使用 ${validatedValue} 获取验证消息中的无效值。 但我遇到了这样的例外。

例外

我在这样的 java 对象中使用了验证注解。

@DateTimeFormat(pattern = "yyyy:MM:dd")
protected Date birthday;

validation_err_message.properties 中的消息定义是这样的。

typeMismatch.birthday=input value of birthday is not valid. ({0}:  ${validatedValue} ).

@Override
@Bean("messageSource")
public MessageSource messageSource() {
    final ResourceBundleMessageSource resourceBundleMessageSource = new ResourceBundleMessageSource();
    resourceBundleMessageSource.setBasename("validation_err_message");
    resourceBundleMessageSource.setDefaultEncoding(StandardCharsets.UTF_8.name());
    resourceBundleMessageSource.setDefaultLocale(Locale.CHINA);
    return resourceBundleMessageSource;
}

验证者的定义：

@Override
public Validator getValidator() {
    final OptionalValidatorFactoryBean validatorFactoryBean = new OptionalValidatorFactoryBean();
    validatorFactoryBean.setProviderClass(org.hibernate.validator.HibernateValidator.class);
    validatorFactoryBean.setValidationMessageSource(this.messageSource);
    return validatorFactoryBean;
}

MessageInterpolator 将是

org.hibernate.validator.messageinterpolation.ResourceBundleMessageInterpolator

自动。
