我正在尝试运行一个简单的spring应用程序但是遇到以下异常:

  

javax.servlet.ServletException:javax.servlet.jsp.JspTagException:否   在代码'label.firstname'下找到的有关区域设置'en_US'的消息。

解决问题的步骤:

  1. 仅将messages_en.properties文件放在src / main / resource文件夹中
  2. 确保文件名正确为messages_en.properties而不是 message_en.properties
  3. 使用mvn clean install进行maven构建时 messages_en.properties文件将出现在 目标/项目名称/ WEB-INF /类/ messages.properties
  4. 签入spring-servlet.xml(名称可能有所不同)并使用     classpath:消息作为messageSource中的基本名称
  5. 它应该可以解决我的问题。

    <bean id="messageSource"
        class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
        <property name="basename" value="classpath:messages" />
        <property name="defaultEncoding" value="UTF-8" />
    </bean>

答案 0 :(得分:11)

您的MessageSource bean定义有点令人困惑。通常,basename是要用于消息解析的文件名的前缀(减去.properties),Spring和JDK ResourceBundle类将附加语言和/或国家/地区缩写。

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="WEB-INF/message_en.properties/Message" />
    <property name="defaultEncoding" value="UTF-8" />
</bean>

例如,如果您打算拥有messages.propertiesmessages_es.propertiesmessages_de.properties等资源文件,则应指定基本名称WEB-INF/messages

邮件包文件的实际名称是什么?

答案 1 :(得分:2)

我有同样的问题,解决方案是:

  1. messages.properties 文件放在源文件夹 src / main / resources

  2. 将Bean定义如下:

    <bean id="messageSource"
             class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:messages" />
    <property name="defaultEncoding" value="UTF-8" />
    

  3. 您看到我在属性中添加了 messages.properties 文件的相同名称而没有 .properties

    那是问题^^

答案 2 :(得分:1)

您必须将“resources”文件夹添加到“Web部署程序集”。之后,将“classpath:messages”替换为“messages”。您需要做的最后一项更改是清理您的项目。

示例:

<bean id="messageSource"
    class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="messages" />
    <property name="defaultEncoding" value="UTF-8"/>
</bean>

这就足够了。 :)

答案 3 :(得分:1)

一个重要的考虑因素是,为了自动重新加载,属性文件不应该在类路径中。服务器通常会缓存属性,所以如果它在classes文件夹中,它就不会真正有效。对于每个Spring文档,在classpath:messages的情况下,cachedSeconds不是-1将不会有任何效果。

答案 4 :(得分:0)

迟到总比没有好。我有同样的问题。这是我如何解决它。 我的文件名是:

messages_的 FR 的.properties

对于法国,因为它是法国春天Tutotrial。但是,我住在荷兰。所以我试图将其重命名为

messages_的 NL 的.properties

它有效。不确定这是否是一个长期的解决方法,但我们会看到。

答案 5 :(得分:0)

要面对这个问题的其他人。

除了所有答案之外,请确保您让.jsp文件由Spring Framework处理。如果直接访问.jsp,则不会处理spring标记,并且您将看到完全相同的错误。简而言之,通过控制器公开.jsps

答案 6 :(得分:-4)

我遇到了同样的问题,但我只是把它留作了messages_properties,它解决了问题
