使用Spring为类级约束验证器启用国际化

我正在使用SpringBoot、SpringJPA、SpringDataREST、SpringHateOAS、HibernateValidator。 我创建了自己的约束验证器

注释：

    Target({ java.lang.annotation.ElementType.TYPE, java.lang.annotation.ElementType.ANNOTATION_TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = { TicketBundleValidator.class })
@Documented
public @interface ValidTicketBundle {

    String message() default "{server.validators.annotations.ValidTicketBundle.message}";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

我创建了测试用例，以验证是否一切正常：

 @Test
    @WithMockUser(roles = "ADMIN")
    public void saveTicketBundleWithWrongDateThrowsException() {
        TicketBundle ticketBundle = new TicketBundle();
        ticketBundle.setCustomer(customer);
        ticketBundle.setStartDate(Instant.now().plus(30, ChronoUnit.DAYS));
        ticketBundle.setEndDate(Instant.now());

        Set<ConstraintViolation<TicketBundle>> constraintViolations = validator.validate(ticketBundle);
        assertEquals(1, constraintViolations.size());
        ConstraintViolation<TicketBundle> constraintViolation = constraintViolations.iterator().next();
        assertEquals("I dati inseriti non sono validi. Verificare nuovamente e ripetere l'operazione.",
                constraintViolation.getMessage());
    }

我在代码中发现了问题。我错了，hibernate validator在根文件夹

validationmessages.properties

（）

我在那里设置了消息，一切正常。

在这个上下文中消息源是如何引用的？@RomanC我以为是Spring Boot自动引用的。嘿@drenda我问了你一个问题？如果你不能回答这个问题，你应该提供一个清晰的问题陈述，包括能够重现问题的代码，如果没有清晰的语句和限定的代码，问题就脱离主题，应该尽快删除，以便在不了解详细信息的情况下为您提供解决方案，或者删除您的帖子，以免干扰开发人员试图争论，而不是提供详细信息。@RomanC类消息源在此上下文中未被引用，无法对您的问题做出适当的响应。但是，你可以简单地避免回答，让知道如何回答的其他用户有空间，而不是要求删除一个记录良好的问题。该问题可能对其他有相同问题的用户有用。谢谢

server.validators.annotations.ValidTicketBundle.message = I dati inseriti non sono validi. Verificare nuovamente e ripetere l'operazione.

 @Test
    @WithMockUser(roles = "ADMIN")
    public void saveTicketBundleWithWrongDateThrowsException() {
        TicketBundle ticketBundle = new TicketBundle();
        ticketBundle.setCustomer(customer);
        ticketBundle.setStartDate(Instant.now().plus(30, ChronoUnit.DAYS));
        ticketBundle.setEndDate(Instant.now());

        Set<ConstraintViolation<TicketBundle>> constraintViolations = validator.validate(ticketBundle);
        assertEquals(1, constraintViolations.size());
        ConstraintViolation<TicketBundle> constraintViolation = constraintViolations.iterator().next();
        assertEquals("I dati inseriti non sono validi. Verificare nuovamente e ripetere l'operazione.",
                constraintViolation.getMessage());
    }

 org.junit.ComparisonFailure: expected:<[I dati inseriti non sono validi. Verificare nuovamente e ripetere l'operazione.]> but was:<[{server.validators.annotations.ValidTicketBundle.message}]>
    at org.junit.Assert.assertEquals(Assert.java:115)
