The content of element type "strutsconfig" must match "(displayname?,descr

配置struts-config.xml 时，出了异常信息：

The content of element type "struts-config" must match "(display-name?,description?,form-beans?,global-exceptions?,global-forwards?,action-mappings?,controller?,message-resources*,plug-in*)". 

解决办法：
struts-config.xml 中的元素顺序有严格的要求，它们的位置不能错位，不然就会报错.

<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">  
<struts-config>  
        <form-beans>  
        </form-beans>  
  
        <global-exceptions>  
        </global-exceptions>  
  
        <global-forwards>  
        </global-forwards>  
  
        <action-mappings>  
            <action path="/index" type="org.apache.struts.actions.ForwardAction" parameter="index-tiles"></action>  
        </action-mappings>  
  
        <controller>  
            <set-property property="processorClass" value="org.apache.struts.tiles.TilesRequestProcessor"/>  
        </controller>  
  
        <message-resources parameter="com.test.struts.ApplicationResources" />  
  
        <plug-in className="org.apache.struts.tiles.TilesPlugin">  
            <set-property value="/WEB-INF/tiles/tiles-defs.xml" property="definitions-config"></set-property>  
        </plug-in>  
</struts-config>  

注意： 
struts-config.xml必须按照 display-name --> description --> form-beans --> global-exceptions --> global-forwards --> action-mappings --> controller --> message-resources --> plug-in 的顺序书写 .
