问题：18:45:28,477 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspException: You must specify the value attribute or nested tag content
at org.apache.struts.taglib.html.MultiboxTag.prepareValue(MultiboxTag.java:195)
at org.apache.struts.taglib.html.MultiboxTag.doEndTag(MultiboxTag.java:162)
解决：
这个错误是由于<html:multibox这个标签空所致
<html:multibox property="kk_CheckBox">
<bean:write name="element" property="idbmqx" />
</html:multibox>
如果idbmqx为空，那么就会报异常的，解决办法就是不要让multibox 为空，或者用<c:if控制一下，为空就不执行
<logic:notEmpty name="element" property="idbmqx">
<html:multibox property="kk_BlacklistVehicle_UserManage_BMQX_SC_CheckBox">
<bean:write name="element" property="idbmqx" />
</html:multibox>
</logic:notEmpty>
<logic:notEmpty 非空判断，不为空时才执行标签体里的内容
