以前看见有人写过<s:select list='@com.test.PubUtil@getPapList("cardType")' name="cardType" listKey="pap_value" listValue="pap_value">
注：com.test.PubUtil.getPapList是个静态方法，
但是我今天这么写(<s:select list='#com.citic.util.PubUtils@getParaList("cardType")' name="documentType1" listKey="PAP_VALUE" listValue="PAP_SHOWCN"> </s:select>)却报了一个错如下（注：这个方法在页面中使用<%=com.citic.util.PubUtils.getParaList("cardType").size()%>取出的list的size确实有值）：
org.apache.jasper.JasperException: tag 'select', field 'list', name 'memberInfo.ctfType': The requested list key '@com.citic.util.PubUtils@getParaList("cardType")' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]

------解决方案--------------------
在struts.properties里面添加：struts.ognl.allowStaticMethodAccess=true，搞定，从此可以自由访问静态方法
