java - Spring MVC 3 I18N/MessageSource 不工作

Question

我正在尝试在 Spring MVC 中配置国际化(使用通过链接更改区域设置)，但是，它似乎根本不起作用:由于某种原因，默认区域设置始终为 ru，尽管默认设置为 en，它们不会使用链接进行更改，无论选择什么语言环境，Spring 消息都会显示为空(messages_de、messages_en 和 messages_ru.properties 确实存在于类路径(src/main/resources)中)。它们包含例如

label.test=Russian 

我将它们称为

<spring:message code="label.test" /> 

在我的 JSP 中。它们并没有这样显示。我认为即使没有错误或警告，也没有找到 messageSource。我真的很感激任何帮助，因为我很长时间都在努力解决这个问题。显然，我错过了一些细节，但我绝对无法捕获问题所在。这是我的配置文件(或最相关的部分)。

您不需要在 basename 值前添加“classpath:”前缀，请尝试按如下方式更改它:

<property name="basename" value="messages" />
