注释中消息的GWT验证框架国际化 [英] GWT validation framework internationalization for messages in annotations

问题描述

阅读此页面后，我发现了一种国际化的方式验证消息。这是通过将每种错误类型的翻译放入 ValidationMessages.properties 文件中完成的。

After having read this page I found a way of internationalizing validation messages. It is done by placing translations of each error type into ValidationMessages.properties files.

javax.validation.constraints.Size.message=The property must be between {min} and {max}
javax.validation.constraints.NotNull.message=The property must not be null

这是错误类型特定的，并不是我在我的应用程序中需要的。我需要验证的bean中每个字段的唯一消息。没有国际化可以使用注释完成。

It is error type-specific and it's not what I need in my app. I need a unique message for each of my fields in validated beans. With no internationalization it can be done using annotations.

@Pattern(regexp = UiLogicUtils.EMAIL_REGEX, message = "Email is invalid.")
private String requesterEmail;

那么，如何才能使这个特定字段的电子邮件无效文本翻译？

So how can I make translations of the "Email is invalid" text just for this specific field?

推荐答案

我不知道这是否是答案，因为我没有使用@Pattern，但在文档中，它说@Pattern的消息字段不是文本，而是消息文件的关键字。看这里：

I don't know if this is the answer, because I have not used @Pattern, but in the docs, it says that the message field of the @Pattern is not a text, but a key into the messages file. Look here:

http://docs.oracle.com/javaee/6/api/javax/validation/constraints/Pattern.html#message （）

默认情况下，message ={javax.validation.constraints.Pattern.message}，它看起来像是ValidationMessages.properties文件中的有效键。我想你只需要指定一个自定义键并使用它。

By default message="{javax.validation.constraints.Pattern.message}" which looks like a valid key in ValidationMessages.properties file. I suppose you only have to specify a custom key and use it.
