最近公司老板有一个想法,请大家一起讨论一下
老板想用SSH架构做基盘,在这个基础上封装一下.现在有这么一个功能
以前struts是这样做验证的,首先就是在struts.xml里配一下
然后就是validation.xml的内容,如下
</formset>
老板想这样多麻烦,他想把这个validation.xml的内容放到数据库里去,表的结构如下图
[img]/upload/attachment/93237/42e00b8f-0f33-39bd-ae5a-73cde3512153.bmp[/img]
功能还是要和以前STRUTS一样，表单提交里要先验证一下，但是这个validation.xml文件是没有的
要到数据库里去取。
这样的话就有多种实现，要么就改改org.apache.struts.validator.ValidatorPlugIn这个类，
要么就写这和这个类一样功能的类，但它原来是读validation.xml文件，现在是读数据库。
大家能否给点实现方式，最好是能贴上代码，谢谢了
[b]问题补充：[/b]
没办法,做员工的只能听老板的话,要么我就写一个类似于ValidatorPlugIn这样的类吧,代替原来的STRUTS验证,用SPRING的AOP可行吗?
[b]问题补充：[/b]
我打算改一下ValidatorPlugin相关类的源代码,我用的是struts2.1.6,我下载了源代码,我把它放到我的工程里面,但是现在报这个错:

说我找不到struts-default.xml这个文件,确实我下的源码里是没有这个文件,但我把这个文件放到SRC目录下了啊,为什么会报错?????
[b]问题补充：[/b]
我知道啊,我们公司用的是STRUTS2.1.6,这里面也有像1.X版本里的验证框架吧,
帮我看看吧,我现在有上面的异常
我把struts-default.xml放到WEB-INF/下面之后又报下面的异常

这是为什么啊?
[b]问题补充：[/b]
王者之剑你好
这个问题怎么解决啊
我肯定少了什么文件没加上去,但我不知道
我就是把STRUTS1.2.6的源码放到我的工程里了,然后删掉原来的struts2-core-2.1.6.jar这个包.
[b]问题补充：[/b]
STRUTS2.1.6源码,上面写错了
[b]问题补充：[/b]
对了还有,没替换这个包之前,我的项目是能跑通的
我的JAR包肯定都有的
只不过源码里没有struts-default.xml这个文件
我还少什么没加上?加在哪儿?
[b]问题补充：[/b]
嗯,改源码确实很难.
STRUTS2.1.6太复杂了,STRUTS1.3的话还可以考虑
大家说说,有什么解决方案吗?
给提供一下
[b]问题补充：[/b]
不会吧,我什么时候说过两个框架要一起用
哎~
能不能提点好的意见,真服了你
我打算用拦截器去做
在ACTION的方法调用前做一把处理
[b]问题补充：[/b]
兄弟,我没说我要一起用啊 大哥
我说的是STRUTS1.3的话,改STRUTS源码比较容易
但我现在用的是STRUTS2.1.6啊
我用拦截器差不多实现这个功能了
[b]问题补充：[/b]
嗯,现在你知道了
不过,你能不能提点好的建议啥的啊
不要只是路过啊
