Hibernate Validator:违反消息语言 [英] Hibernate Validator: Violation Message Language

问题描述

我有一个测试类，用于测试一个域模型，该域模型带有例如@NotNull

I have a test class where I am testing a domain model which is annotated with e.g. @NotNull

在我的测试班中，我首先获得验证器

In my test class I am first getting the validator

private static Validator validator;

@BeforeClass
public static void setup() {
    validator = Validation.buildDefaultValidatorFactory().getValidator();
}

稍后我有一个JUnit测试，用于测试领域模型(比如说一个人)

Later I have a JUnit Test where I am testing the domain model (lets say a Person)

Set<ConstraintViolation<Person>> violations = validator.validate( aPerson );

让我们说，我想检索我做的第一条违规消息:

Lets say, I want to retrieve the first violation Message I do:

String violationMessage = violations.iterator().next().getMessage()

我没有在@NotNull批注上设置任何自定义违规消息.因此，休眠验证器将从hibernate-validator-jar中的资源包中拉出默认消息.我的路径如下所示:

I haven't set any custom violation message on the @NotNull annotation. So hibernate validator will pull the default message from the Resource Bundle which is in the hibernate-validator-jar. My path looks like this:

hibernate-validator-5.3.5.Final.jar
    - org
        - hibernate
            - validator
                ...
                ResourceBundle 'Validation Messages'

在此资源包中，支持多种语言(英语，德语，法语，...)

In this Resource Bundle there are quite a few languages supported (English, German, French, ...)

示例

@NotNull违反德语消息

@NotNull violation message in German

javax.validation.constraints.NotNull.message     = darf nicht null sein

@NotNull英文违规消息

@NotNull violation message in English

javax.validation.constraints.NotNull.message     = may not be null

问题:

在测试时，如何强制Hibernate Validator从资源包中为违规消息选择特定的语言?现在，我收到英语违规消息.但是，在另一台机器上是德语.

When I am testing, how can I enforce Hibernate Validator to choose a specific language for the violation message from the Resource Bundle? Right now, I am getting English violation messages. However, on another machine German.

推荐答案

参考文档摘要:

默认情况下，在查找包中的消息时将使用JVM的默认语言环境(Locale#getDefault()).

By default, the JVM's default locale (Locale#getDefault()) will be used when looking up messages in the bundle.

在不触动源代码的情况下，或者在不干扰操作系统/用户的情况下，尝试执行以下操作以解决西班牙语消息:

Without touching source code or fiddle with your OS/User seetings, try this for spanish messages:

java -Duser.country=ES -Duser.language=es
