Spring boot MessageSource在应用程序中不工作。属性

Question

我正在将spring MVC转换为spring boot（2.0.3版本）项目。

我在spring boot中使用此功能，它可以工作：

@Bean
public MessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasenames("classpath:/locale/normal/message", "classpath:/locale/validation/message");
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
}

我尝试使用Spring引导自动配置（通过application.properties）如下（删除上面的手动bean配置）：

spring.messages.basename=classpath:/locale/normal/message,classpath:/locale/validation/message

我在下面试过了，它也不起作用：

spring.messages.basename=/locale/normal/message,/locale/validation/message

我看了他们的留档：

# INTERNATIONALIZATION (MessageSourceProperties)
spring.messages.always-use-message-format=false # Whether to always apply the MessageFormat rules, parsing even messages without arguments.
spring.messages.basename=messages # Comma-separated list of basenames (essentially a fully-qualified classpath location), each following the ResourceBundle convention with relaxed support for slash based locations.
spring.messages.cache-duration= # Loaded resource bundle files cache duration. When not set, bundles are cached forever. If a duration suffix is not specified, seconds will be used.
spring.messages.encoding=UTF-8 # Message bundles encoding.
spring.messages.fallback-to-system-locale=true # Whether to fall back to the system Locale if no files for a specific Locale have been found.
spring.messages.use-code-as-default-message=false # Whether to use the message code as the default message instead of throwing a "NoSuchMessageException". Recommended during development only.

我将消息属性文件放在类路径中：

src\main\resources\locale\normal
src\main\resources\locale\validation

我尝试了很多组合，但都不起作用，为什么？

我遇到的错误：

javax.servlet.jsp.JspTagException: No message found under code 'login.timeout' for locale 'en'.

（我很确定消息代码在我的所有语言环境的属性文件中。）

我正在使用Spring标签加载本地化消息：

<spring:message code="${param.error}" />

Answer 1

确保除了特定于语言环境的messages.properties之外，还有默认messages.properties

Answer 2

尝试使用#代替$-
