Spring 4 Hibernate 验证器本地化消息

Question

我尝试使用自定义休眠消息进行本地化，但无法使其工作。我的经过验证的类如下所示:

@Entity
@Table(name = "USERS")
public class UserEntity extends AbstractBaseEntity implements UserDetails {

    @NotNull
    @Column(unique = true, nullable = false)
    @Size(min = 5, max = 30)
    private String username;

这是我的 spring 配置的一部分:

<!-- Localization of hibernate messages during validation!-->
<bean id="validationMessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:validation" />
</bean>

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

在资源中，我有两个验证文件:validation_en.properties 和validation_pl.properties 这是示例条目:

NotNull.UserEntity.username=Username can't be empty!

当我显示验证错误时，我看到标准消息“可能不为空”，而不是我的自定义和本地化消息。我做错了什么？预先感谢您的帮助，最诚挚的问候

您需要做的是@NotNull(message = "{error.username.required}")

@Entity
@Table(name = "USERS")
public class UserEntity extends AbstractBaseEntity implements UserDetails {

@NotNull(message = "{error.username.required}")
@Column(unique = true, nullable = false)
@Size(min = 5, max = 30)
private String username;

在资源文件夹中的 validation_en.properties 属性文件中

error.username.required=Username can't be empty!

在 Spring 配置中:

<mvc:annotation-driven validator="validator">
</mvc:annotation-driven>

 <!-- Localization of hibernate messages during validation!-->
 <bean id="validationMessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:validation" />
 </bean>

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