Spring cvc-elt.1: Cannot find the declaration of element 'beans'. 

<script type="text/javascript"> document.body.oncopy = function () { if (window.clipboardData) { setTimeout(function () { var text = clipboardData.getData(&quot;text&quot;); if (text &amp;&amp; text.length &gt; 300) { text = text + &quot;\r\n\n本文来自CSDN博客，转载请标明出处：&quot; + location.href; clipboardData.setData(&quot;text&quot;, text); } }, 100); } } </script><script type="text/javascript"> function StorePage() { d = document; t = d.selection ? (d.selection.type != 'None' ? d.selection.createRange().text : '') : (d.getSelection ? d.getSelection() : ''); void (keyit = window.open('http://www.365key.com/storeit.aspx?t=' + escape(d.title) + '&amp;u=' + escape(d.location.href) + '&amp;c=' + escape(t), 'keyit', 'scrollbars=no,width=475,height=575,left=75,top=20,status=no,resizable=yes')); keyit.focus(); }</script>

这个的格式异常：比如spring-aop-2.0.xsd写成spring-aop.xsd 就会爆出Spring cvc-elt.1: Cannot find the declaration of element 'beans'.
