如何在 Hibernate 验证器中添加自定义错误消息

我有一个像这样的简单类，

import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.Length;

public class Form implements Serializable {
   @NotNull
   @Length(min = 2, max = 20)
   private String lastName;
}

类路径中有 messages.properties 文件。然后它通过 Spring bean 加载，如下所示，

<bean name="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="validationMessageSource">
        <ref bean="resourceBundleLocator"/>
    </property>
</bean>

<bean name="resourceBundleLocator" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>classpath*:messages.properties</value>
        </list>
    </property>
</bean>

我想要的只是获取根据验证的 bean 定制的错误消息。换句话说，我想让每个 ConstraintViolation 对象返回我在属性文件中定义的错误消息，而不是默认消息。是否可以添加具有类似格式 {xxx.yyyy.zzzz} 的值的消息属性并从 messages.properties 文件引用该消息？

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    Set<ConstraintViolation<Form>> inputErrors = validator.validate(form);

如果我想自定义@NotNull和@Length的默认消息，我该怎么做？

我在 Hibernate 验证方面的经验是零，任何示例代码或分步指南将不胜感激。

I have a simple class like this,

import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.Length;

public class Form implements Serializable {
   @NotNull
   @Length(min = 2, max = 20)
   private String lastName;
}

I have messages.properties file in the classpath. It's then loaded via Spring bean as follows,

<bean name="validator"
      class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="validationMessageSource">
        <ref bean="resourceBundleLocator"/>
    </property>
</bean>

<bean name="resourceBundleLocator" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basenames">
        <list>
            <value>classpath*:messages.properties</value>
        </list>
    </property>
</bean>

All I want is to get error messages customized according to the bean validated. In other words I want to have each ConstraintViolation object return the error message I have defined in my property file instead of the default one. Is it possible to add message property with a value like this format {xxx.yyyy.zzzz} and refer that message from the messages.properties file ?

ValidatorFactory factory = Validation.buildDefaultValidatorFactory();
    Validator validator = factory.getValidator();
    Set<ConstraintViolation<Form>> inputErrors = validator.validate(form);

If I want to customize the default message for @NotNull and @Length, how can I do that?

My experience on Hibernate validation is zero, Any sample code or step by step guide would be appreciated.
