The content of element type "struts-config" must match "(display-name?,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 .
