java - 资源包 Spring

Question

如何在从 AbstractController 扩展的类中访问 Spring MVC 资源包中的消息？

我试过 getMessageSourceAccessor().getMessage("a.message");但它抛出了这个异常:

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.context.NoSuchMessageException: No message found under code 'a.message' for locale 'en'.

当我在 jsp 中执行相同的操作时，它会起作用

<spring:message code="a.message"/>

您可以在 org.springframework.web.servlet.support.RequestContext 类上使用 getMessage() 方法变体之一。像这样的东西有效:

protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {
    RequestContext ctx = new RequestContext(request);
    String messageFromBundle = ctx.getMessage("a.message");
}
