struts2笔记

如果要通过ognl访问静态方法，必须在struts.properties或者struts.xml中将选项struts.ognl.allowStaticMethodAccess设置为true .

例如:
<s:property value="@java.lang.String@format('foo %s', 'bar')"/>
<s:property value="@com.dw.knowledge.global.GGlobals$SYSTEM@WEB_ROOT"/>
<s:property value="@com.dw.knowledge.global.GGlobals$SYSTEM$SystemCodeStyle@MAIL_SERVER.name()"/>
<s:property value="@com.dw.knowledge.global.GGlobals$SYSTEM$SystemCodeStyle@MAIL_SERVER.ordinal()"/>
<s:property value="@com.dw.knowledge.global.GGlobals@SYSTEM@containsLimitWord('22')"/>
<s:property value="@com.dw.knowledge.util.CalendarUtil@getCalenDarUtilDate('1')"/>
<s:property value="@com.dw.knowledge.util.CalendarUtil@format0"/>
<s:property value="@com.dw.knowledge.util.CalendarUtil@format1"/>
