这几个值，都不为空。但下一句语句就抛异常
在return 那行下个断点看看，dao 和 entity 里有个为空吧。
2009-08-26 01:59 ERROR org.hibernate.property.BasicPropertyAccessor - IllegalArgumentException in class: net.cnyun.member.entity.base.BaseNational, getter method of property: naId
这个问题解决了，原因是National和Member表是有主外建的联系。而我在页面是这么写的
控件的名字是 member.meNational 这样虽然可以取到值，但会抛出异常而无法保存。只需将名字修改为member.meNational.naId就可以保存值了。
<select name="member.meNational" id="member.meNational">
<!-- <#if nationaList??>
<#list nationaList as mz> -->
<option value="${mz.naId}">${mz.national}</option>
<!-- </#list>
</#if>-->
</select>谢谢楼上的朋友，现在结贴。之前的异常也是由于dao没能实例化造成，粗心引起的。在此谢过你们的帮助。
