springmvc配置的国际化资源文件显示为???key???的错误原因

 问题概述：

在spring mvc 的jstl view 视图解析器中 使用jstl <fmt:message key=”“”></fmt> 不不要绑定也可以正常显示，这里却显示标题上的错误，

一般我们遇到乱码都是直接排查编码问题，为此我耽误接近3小时，真是可恨，这里直接绑定就好；

 

1 <fmt:bundle basename="messages">
2      <fmt:message key="messages.username"></fmt:message>
3      </fmt:bundle>

 

大纲图：

 

基本配置图：

这里只是起到对应作用，前提你要会spring mvc
