title: Why I can't use tag of <spring:message?
body: <p>Using in my jsp like:<br>
   <code>&lt;spring:message code="key1"/&gt;</code> ,
  I got error:
    ** <code>Root cause is: No message found under code 'key1' for locale 'zh_CN'. javax.servlet.jsp.JspTagException: No message found under code 'key1' for locale 'zh_CN'. at org.springframework.web.servlet.tags.MessageTag.doStartTagInternal(MessageTag.java:184) at org.springframework.web.servlet.tags.RequestContextAwareTag.doStartTag(RequestContextAwareTag.java:79) at</code> </p>
  
  <p>And the following is my code:</p>
  
  <pre><code>&lt;bean id="messageSource"        class="org.springframework.context.support.ReloadableResourceBundleMessageSource"&gt;
          &lt;property name="basename" value="com.bk.message.Message" /&gt;
          &lt;property name="defaultEncoding" value="UTF-8" /&gt;
          &lt;property name="useCodeAsDefaultMessage" value="false" /&gt;
      &lt;/bean&gt;
  </code></pre>
  
  <p>here is my properties:</p>
  
  <pre><code>Message_zh_CN.properties under folder src/com/bk/message  
  key1=This
  </code></pre>
